Use this variable if you want to the JDE to use the same classpath for

of this variable is a list of strings, each of which specifies a
path. The JDE converts this list to a colon- or semicolon-separated
list before inserting in the compiler or vm command line. 

The path may start with a tilde (~) or period (.) and may include
environment variables. The JDEE replaces a ~ with your home directory.
If `jde-resolve-relative-paths-p' is nonnil, the JDEE replaces the
. with the path of the current project file. The JDEE replaces each
instance of an environment variable with its value before inserting it
into the command line.

You can specify different classpaths for compiling, running and
debugging applicaitons. Use `jde-compile-option-classpath' to specify
the compilation classpath, `jde-run-option-classpath' to specify the
run classpath, and/or `jde-db-option-classpath' to specify the debug
classpath. You can use these variables together. For example, suppose
that you need to use one classpath for compilation and other for
running and debugging. You could do this by setting
`jde-compile-option-classpath' to the compile classpath and
`jde-global-classpath' to the run and debug classpath. If you set
`jde-global-classpath', the JDE uses it to construct the classpath for
any operation for which you do not set the operation-specific
classpath variable (e.g., `jde-compile-option-classpath'). 

If you do not set `jde-global-classpath', the JDE uses the operation-specific
classpath if it is set. If neither the global nor the
operation-specific classpath is set, the JDE does not generate a
-classpath argument for the operation, e.g., compile or run a Java
class. In this case, the operation uses the value of the CLASSPATH variable

;; Revision 1.321  2003/11/29 05:28:26  paulk
;; Change abbreviation for throws from throw to thro to avoid inadvertent completion of throw to throws.
;;
;; Revision 1.320  2003/11/25 06:48:02  paulk
;; Fix regression that was causing abbrev-mode to be enabled for JDEE buffers even when jde-enable-abbrev-mode was set to nil. Also, enable abbrev-mode in all open JDEE buffers for the current project as a side effect of setting jde-enable-abbrev-mode on.
;;
;; Revision 1.319  2003/10/23 03:53:22  paulk
;; Added fix for compatibility with old versions of XEmacs. Thanks to Len Trigg.
;;
;; Revision 1.318  2003/10/14 05:07:40  paulk
;; jde-count-open-java-buffers now saves match data before doing a string-match. This fixes compatibility problem with emacs-w3m.
;;
;; Revision 1.317  2003/09/28 05:09:38  paulk
;; Created a new buffer-local variable, jde-buffer-project-file, that stores
;; the path of the project file for the current Java buffer. Updated
;; jde-get-current-project-buffers to use this variable to test whether
;; a given buffer is part of the current project. This should improve
;; the performance of this function and hence loading of project files,
;; which depends on it.
;;
;; Revision 1.316  2003/09/24 05:13:15  paulk
;; Changed jde-normalize-path to support use of relative paths in .emacs
;; files.  Previously, if a relative path appeared in a variable, e.g.,
;; jde-global-path, that was set for the current project by the user's
;; .emacs file (as opposed to a project file), jde-normalize-path would
;; resolve the variable relative to the source buffer directory. Now
;; jde-normalize-path resolves it relative to the location of the nearest
;; project file in the source buffer directory tree. If the directory
;; tree does not contain a project file, jde-normalize-path resolves the
;; path relative to the source buffer directory.
;;
;; Revision 1.315  2003/08/25 05:33:13  paulk
;; Added item to the Documentation submenu to display the Javadoc Tool Reference.

;; Makes jde-cygpath a noop if system-type is not cygwin.
;;
;; Revision 1.313  2003/07/08 05:54:16  paulk
;; Add documentation for jde-jeval- functions.
;;
;; Revision 1.312  2003/07/01 05:10:58  paulk
;; Adds a jde-bsh-compile-mode-eval function. This function
;; is intended to be used by plugins to invoke Java development
;; utilities, such as source code style checkers, that emit
;; compiler-like error messages.  Displaying the output in a
;; compilation-mode buffer enables the user to use compilation-mode's
;; error message navigation and hyperlinking capabilities.
;;
;; Revision 1.311  2003/06/26 05:36:13  paulk
;; Fix regression introduced by changes to jde-root-dir-p in previous version.
;;
;; Revision 1.310  2003/06/26 04:45:36  paulk
;; - Now requires jde-autoloads for XEmacs installations that use
;;   the independently distributed version of the JDEE rather than
;;   the version that is packaged with XEmacs.
;;
;; - Provides a workaround for a bug in file-exists-p in the cygwin
;;   version of XEmacs that prevented the JDEE from finding project
;;   files. The bug is that file-exists-p denies the existence of
;;   files whose native Windows paths (file-truename) end in a slash.
;;
;; Revision 1.309  2003/06/24 04:08:44  paulk
;; - Update jde-symbol-p to recognize variables defined by autoloaded packages
;;   that have not yet been loaded. Thanks to Martin Schwamberger.
;;
;; - Fix jde-compile-jde to compile jde-xemacs.el only on Xemacs.
;;
;; Revision 1.308  2003/06/18 10:49:20  paulk
;; Enhance jde-autoload-update to save and kill jde-autload.el buffer.
;;
;; Revision 1.307  2003/06/17 06:11:45  paulk
;; - Change JDE->Documentation->Generate to Generate All.
;; - Add JDE->Documentation->Generate Buffer.
;;
;; Revision 1.306  2003/05/03 09:01:55  paulk
;; Require jde-class package.
;;
;; Revision 1.305  2003/04/28 04:49:57  paulk
;; jde-mode now installs plugin menu if any plugins are installed on the user's system and the plugins have menus. beanshell startup now includes plugin classpaths in the beanshell classpath.
;;
;; Revision 1.304  2003/04/17 16:56:39  jslopez
;; Points C-c C-v C-k from jde-bsh to jde-bsh-run.
;;
;; Revision 1.303  2003/04/16 04:15:26  paulk
;; Restore require for jde-plugins package. This package is now in the CVS repository.
;;
;; Revision 1.302  2003/04/11 22:53:08  jslopez
;; Removes require clause for missing library, jde-plugins. It was
;; breaking the byte compilation.
;;
;; Revision 1.301  2003/04/09 04:03:23  paulk
;; Moved jde-find-jde-data-directory to jde-util package.

;; Revision 1.299  2003/03/28 05:33:30  andyp
;; XEmacs optimizations for JDEbug and efc.
;;
;; Revision 1.298  2003/03/04 10:15:07  paulk
;; Updated to use the new bsh-get-process method provided
;; by bsh to get its process. This is necessary to insulate
;; clients from the fact that bsh now uses a bsh-buffer
;; object to wrap the Emacs Lisp buffer object that specifies
;; the associated process.
;;
;; Revision 1.297  2003/02/25 16:00:30  jslopez
;; Fixes typo.
;;
;; Revision 1.296  2003/02/25 06:58:07  paulk
;; - Moved jde-debug command to jde-db.el and reimplemented it so that

;;
;; - Changing jde-mode-abbreviations now updates all the Java source

;; jde-get-jdk-dir now uses javac instead of java as the JDK program to look

;; instances of java that were not installed as part of a JDK.
;;
;; Revision 1.291  2003/01/26 16:40:37  paulk
;; Fix jde-get-global-classpath to normalize the value of CLASSPATH using

;;
;; Revision 1.290  2003/01/26 08:09:46  paulk

;;
;; Revision 1.288  2003/01/21 05:37:01  paulk

;;
;; - Replaces Speedbar menu item with a Browse submenu

;; Revision 1.257  2002/08/27 05:28:02  paulk
;; Fixed cygwin support bug in jde-root-dir-p. Thanks to Andy Piper.
;;
;; Revision 1.256  2002/08/07 06:36:14  paulk
;; Removed code intended to eliminate spurious warnings when byte-compiling the JDEE. The
;; removed code now resides in a separate package, jde-compat.el. Thanks to Andy Piper
;; for suggesting this restructuring. Also fixed a number of compiler warnings caused
;; by genuine bugs.
;;
;; Revision 1.255  2002/06/21 05:15:19  paulk
;; Conditioned the :set-after option out of jde-jdk for versions of Emacs
;; earlier than Emacs 21. This is so users will not need Emacs 21 to run
;; the JDEE. Thanks to YAMANO Yuji.
;;
;; Revision 1.254  2002/06/21 04:52:27  paulk
;; XEmacs compatibility fix: set directory sep character to be a forward slash
;; for project files. This fixes a project file save bug that corrupted
;; project files under some circumstances. Thanks to Hanson Char <HChar@realm.com>
;; for diagnosing this bug.
;;
;; Revision 1.253  2002/06/17 07:41:37  paulk
;; Updated version number.
;;
;; Revision 1.252  2002/06/17 07:24:07  paulk
;; Updated the JDEE's applet debugging command to
;; work with its new jdb interface.
;;
;; Revision 1.251  2002/06/12 06:58:42  paulk
;; XEmacs compatibility fix: removed unsupported :set-after clause from
;; the definition of jde-jdk. The result may be that JDK registry settings
;; may not persist in some cases on XEmacs. I will restore this clause
;; as soon as XEmacs supports it.
;;
;; Revision 1.250  2002/06/04 20:13:26  mnl
;; JDE menus are now defined by custom-variables. This allows especially
;; project specific menus that are automatically switched when changing
;; projects (as is usual with jde-... custom variables).
;;
;; Revision 1.249  2002/05/31 19:02:27  mnl
;; Added new template to generate a new interface from scratch.
;;
;; Revision 1.248  2002/05/29 04:47:30  paulk

;; Revision 1.246  2002/05/23 05:28:47  paulk
;; Patch jde-root-dir-p to support the Cygwin version of Xemacs 21.4.6, which
;; accepts native Windows path names. Thanks to Michael Lipp.
;;
;; Revision 1.245  2002/05/20 05:03:31  paulk
;; Used defcustom's :set-after option to specify that jde-jdk should be
;; set after jde-jdk-registry. This is necessary to prevent jde-jdk-registry
;; from resetting jde-jdk to the first registered jdk rather than the JDK
;; selected by the user.
;;
;; Revision 1.244  2002/05/11 23:02:40  jslopez
;; Removes control characters.
;;
;; Revision 1.243  2002/04/18 04:21:07  paulk

;; Renamed jde-db-source-directories. The new name is jde-sourcepath.
;;
;; Revision 1.238  2002/03/24 05:34:55  paulk
;; Patched jde-save-close-buffer and jde-save-variable to use find-buffer-visiting
;; to find the buffer containing the prj.elf file instead of looping through
;; the buffer list.
;;
;; Revision 1.237  2002/03/22 05:28:59  paulk
;; Updated doc for jde-build-function variable.
;; Updated my email address.
;;
;; Revision 1.236  2002/03/21 12:34:53  paulk
;; Fixes the jde-build-function variable to default to jde-make.
;;
;; Revision 1.235  2002/03/21 12:30:51  paulk
;; Removed jde-java-build-function. It never worked reliably.
;;
;; Revision 1.234  2002/03/12 04:40:44  paulk
;; Corrected minimum eieio version number.
;; Removed initarg for class slots to silence eieio warning.

;; Updates to reflect changes made to beanshell.el
;;
;; Revision 1.230  2002/02/21 05:32:04  paulk
;; Adds the following enhancements to the JDEE's expression
;; search functionality.
;;
;;   - A new customization variable, jde-find-granularity,
;;     that allows you to specify the granularity of the
;;     search (character, word, or line).
;;
;;   - A new command, JDE->Search->Expression... (jde-find-dlg),
;;     that allows you to set all search options interactively
;;     in a popup dialog buffer.
;;
;; Revision 1.229  2002/02/17 13:42:20  paulk
;; jde-submit-problem-report command now includes versions of required packages.

;;
;; Revision 1.226  2002/01/19 06:42:22  paulk
;; Minor updates.
;;
;; Revision 1.225  2002/01/18 12:49:42  paulk
;; Added a new hook, jde-project-hooks. This variable lists functions to be run
;; when the JDEE switches to a new project.
;;
;; Revision 1.224  2002/01/15 05:53:58  paulk
;; Now requires comint.
;;
;; Revision 1.223  2001/12/19 08:00:43  paulk
;; Update jde-semantic-max-version to allow 1.4beta13.
;;
;; Revision 1.222  2001/12/04 05:39:22  paulk
;; Fixed JDEbug menu related bug.
;;
;; Revision 1.221  2001/11/30 10:46:08  jslopez
;; Fixes the definition of jde-emacs21p.
;; Changes the name from jde-emacs21-p to jde-emacs21p.
;;
;; Revision 1.220  2001/11/30 04:22:13  jslopez
;; Fixes another compilation warning...

;; Fixes compilations warnings in emacs 21.
;;
;; Revision 1.217  2001/11/28 08:25:29  paulk
;; Updated jde-cygwin-path-converter-cygpath to minimize calls to cygpath command. This function now invokes cygpath only if the cygwin path does not begin with /cygdrive and has a root that has not previously been converted.
;;
;; Revision 1.216  2001/11/25 20:56:45  paulk
;; Added functions jde-java-major-version and jde-java-minor-version.
;;
;; Revision 1.215  2001/11/24 15:00:48  paulk
;; Expanded doc strings for jde-jdk-registry and jde-jdk to clarify their usage.
;;
;; Revision 1.214  2001/11/13 07:31:26  paulk
;; Fixed jde-java-version to return the version of Java on the system command path
;; when the user does not specify the version and the Beanshell is not running.
;; This eliminates the infinite recursion caused by starting the Beanshell to
;; find the version, which is needed to start the Beanshell.
;;
;; Revision 1.213  2001/11/12 12:09:30  jslopez
;; Adds a new option `jde-check-version-flag'
;; to customize the behavior of the new
;; `jde-check-versions' feature.
;;
;; When `jde-check-version-flag' is non-nil
;; `jde-check-versions' will check for correct
;; versions of the CEDET libraries required
;; by the JDE.
;; If nil it only checks if these libraries
;; are available.
;;
;; Fixes some doc strings to follow
;; Emacs conventions and removed the set up
;; of the `jde-which-method-idle-timer'
;; in `jde-mode' because it has been
;; moved in jde-java-grammar.el with the
;; other stuff which need Semantic.
;;
;; Submitted by David Ponce
;;
;; Revision 1.212  2001/11/11 23:00:26  jslopez
;; Fixing typo.
;;
;; Revision 1.211  2001/11/11 18:10:44  jslopez
;; Adds version checking to jde for speedbar, semantic, and eieio.
;; If the wrong version of one of the packages is installed, it
;; shows an error to the user and stops loading jde.
;;
;; Revision 1.210  2001/11/11 07:18:17  paulk
;; Moves all the `jde-mode' code depending on Semantic
;; into `jde-parse-semantic-default-setup' which is now run as a
;; `semantic-init-hooks' ensuring that at this point the buffer is ready
;; for parsing.
;;
;; This solves a nasty problem of synchronization between `jde-mode' and
;; Semantic initialization.  This problem was particularly annoying in
;; XEmacs where `jde-mode' buffers were not parsed the first time.  In
;; some rare conditions the problem occurred with Emacs too.
;;
;; Thanks to David Ponce.
;;
;; Revision 1.209  2001/11/08 06:14:23  paulk
;; Updated to support semantic 1.4 beta 12. Thanks to David Ponce.
;;
;; Revision 1.208  2001/11/04 04:43:53  paulk

;;
;; Revision 1.207  2001/10/31 08:58:43  paulk
;; Emacs 21 compatibility fix: added support for browse-url-new-window-flag variable (replaces browse-url-new-window-p in Emacs 21).
;;
;; Revision 1.206  2001/10/30 06:44:48  paulk
;; Added the Event Source wizard to the JDE menu.
;;
;; Revision 1.205  2001/10/27 22:30:38  paulk
;; Eliminated jde-mode-internal as its only purpose was to facilitate debugging jde-mode. Moved the invocation of the hook functions to be the last form in jde-mode. Thanks to David Ponce for noticing this latter bug.
;;
;; Revision 1.204  2001/10/22 02:45:35  paulk
;; Bumped version number to 2.2.9beta5.
;;
;; Revision 1.203  2001/10/21 14:49:54  jslopez
;; Added require jde-ant.
;; Added jde-show-complete-options
;; Added jde-show-wiz-options
;; Added jde-show-ant-options
;; Added wiz, complete, and ant to the menu under JDE -> Project -> Options
;;
;; Revision 1.202  2001/10/21 14:19:11  jslopez
;; Added require jde-ant; now the use of ant does not require any
;; extra customization.
;;
;; Revision 1.201  2001/10/19 09:53:21  paulk
;; Cygwin/XEmacs compatibility fix: Now uses
;; mswindows-cygwin-to-win32-path function if defined.
;; Thanks to Andy Piper.
;;
;; Revision 1.200  2001/10/16 05:06:44  paulk
;; Fixed bug in jde-java-version command. Thanks to Jim Davidson.
;;
;; Revision 1.199  2001/10/15 03:37:11  paulk
;; - XEmacs compatibility fix. Fixed bug that caused the JDE
;;   to append "(jde-save-variable " to every line of a prj.el
;;   file. This bug was due to a conditional expression that
;;   depended on the file sep char being a forward slash when
;;   by default it is a backslash on XEmacs.
;;
;; - XEmacs cygwin compatibility fix. Fixed bug in the
;;   code that builds classpaths that garbled the resulting
;;   classpath.
;;
;; - Fixed all compiler warnings in both Emacs and XEmacs.
;;
;; Revision 1.198  2001/10/04 11:18:27  paulk
;; Fixes bug in jde-get-jdk-dir that caused it to return
;; an incorrect path when looking for the directory on
;; the PATH environment variable.
;;
;; Revision 1.197  2001/10/01 12:08:38  paulk
;; Fixes bugs in jde-java-version function.

;; Added the following variables: jde-jdk-registry and jde-java-environment-variables.
;;
;; Revision 1.194  2001/09/27 14:57:44  jslopez
;; Updated the menu to reflect new method name, jde-help-browse-jdk-doc.
;;
;; Revision 1.193  2001/09/16 17:47:33  paulk
;; - Replaced jde-jdk-directory with jde-jdk. The new variable specifies both the version
;; and the location of the JDK currently being used by the JDE.
;;
;; - Semantic setup code moved to jde-java-grammar.el. Thanks to David Ponce.
;;
;; - In `jde-mode-internal', `jde-current-project' set to "" instead of nil
;; when there is no project file.  This avoid setting twice the startup
;; values because `jde-reload-project-file' assumes that
;; `jde-current-project' is "" when not found. Thanks to David Ponce.
;;
;; Revision 1.192  2001/09/05 06:09:50  paulk
;; Added the function/command jde-get-jdk-dir. This command gets the root
;; directory of the JDK currently being used by the JDE. The JDK used
;; by the JDE is either the directory specified by jde-jdk-directory
;; or by the path environment variable.
;;
;; Revision 1.191  2001/09/05 04:44:30  paulk
;; * Add a new command jde-java-version that gets the version of Java being used by the JDE. Note that this command uses the BeanShell.

;;
;; Revision 1.184  2001/08/04 05:34:18  paulk
;; Reorganized JDE menu somewhat.
;;

;; Fixes JDE->Help->JDE User Guide function so that it works on XEmacs.
;;
;; Revision 1.180  2001/07/18 02:41:27  paulk
;; NT/XEmacs compatibility fix: jde-find-project-file now returns paths with forward slashes as directory sep characters on NT/XEmacs.
;;
;; Revision 1.179  2001/07/17 05:42:15  paulk
;; Bump version number.
;;
;; Revision 1.178  2001/07/16 13:36:30  paulk
;; Adds jde-enable-senator variable.
;;
;; Revision 1.177  2001/07/16 13:23:48  paulk
;; Fixed bug in jde-save-needs-saving-p that caused the JDE not to save variables whose customized value is nil.
;;
;; Revision 1.176  2001/07/08 04:37:28  paulk
;; Added compatibility fixes for NT/XEmacs use of backslash as the
;; default directory sep character. Thanks to William Griswold <wgg@cs.ucsd.edu>

;;
;; Removes the customization variable, jde-build-use-make.
;;
;; Thanks to Jason Stell jason.stell@globalone.net.
;;
;; Revision 1.172  2001/06/07 04:08:12  paulk

;; Revision 1.163  2001/04/24 08:01:21  paulk
;; Define new function jde-toggle-project-switching.
;;
;; Revision 1.162  2001/04/20 20:52:13  paulk
;; Bug fix: JDE no longer overwrites local version of after-change-functions. Thanks to David Ponce.
;;
;; Revision 1.161  2001/04/19 04:40:57  paulk
;; Updated version number.
;;
;; Revision 1.160  2001/04/17 04:18:03  paulk
;; XEmacs compatibility fix: pass nil third argument to local-variable-if-set-p. Thanks to Nick Sieger.
;;
;; Revision 1.159  2001/04/16 05:41:27  paulk
;; - jde-build-classpath now optionally takes a symbol representing a string of paths.
;; - Normalized JDK doc path.
;;   Thanks to Nick Sieger for both enhancements.
;;
;; Revision 1.158  2001/04/11 03:13:55  paulk
;; This is a major update to the JDE project file system to support hierarchical
;; project files. The enhanced  code remembers which project files set
;; options and will save them back to the appropriate project
;; file when the project is saved.
;;
;; When the values of variables are newly customized, the new value is saved in
;; the deepest project file found relative to the buffer where
;; `jde-save-project' is invoked.  Thus, the buffer where you save the project
;; controls in whic project file newly customized values are saved.
;;
;; The implementation boils down to associating a new property `jde-project'
;; with each symbol that has been saved to a project file.   The property's
;; content is an alist of cons cells that look like ("<project file path>"
;; <saved value>).
;;
;; A  side-effect of the changes is where do relative paths resolve to now
;; that path-related options can be set by multiple project files?  The project
;; system solves that problem by resolving relative paths relative to the project
;; file that defines the option.
;;
;; Thanks to "Nick Sieger" <nsieger@bitstream.net> for contributing this
;; enhancement.
;;
;; Revision 1.157  2001/04/11 02:33:42  paulk
;; The JDE now replaces occurrences of lib directories in  classpaths
;; with the jar and zip files that those directories
;; contain. This means that you no longer have to include
;; jar and zip files explicitly in classpaths. See
;; jde-expand-classpath-p and jde-lib-directory-name for details.
;;
;; Revision 1.156  2001/03/30 18:04:28  paulk
;; Fix jde-save-variables to save overrides of variables customized in the user's .emacs file. Thanks to Nick Sieger <nsieger@bitstream.net> for providing this fix.
;;
;; Revision 1.155  2001/03/30 08:46:29  paulk
;; Implements hierarchical project files. The JDE saves only variables that have been customized for the current session in project files. The JDE now loads project files in the following manner. It first sets all the JDE variables to their Emacs startup values (i.e., the default value or the value saved in your .emacs file). It then loads all the project files in the directory tree containing the current source buffer, starting with the topmost file. Thanks to Nick Sieger for contributing to this enhancement.
;;
;; Revision 1.154  2001/03/29 06:19:15  paulk
;; - jde-save-project now prompts you to enter the directory in which to save a new project file.
;;
;; - jde-save-project-in prompts you to enter the directory in which to save a new or existing project file.
;;
;; Revision 1.153  2001/03/29 04:16:16  paulk
;; Adds support for relative paths. The JDE now converts relative paths to absolute paths by appending the relative path to the path of the project file for the current source buffer.
;;
;; Revision 1.152  2001/03/29 02:44:32  paulk
;; Replaced jde-find-exec with executable-find, which is defined by executable.el available with both the Emacs and XEmacs distributions.
;;
;; Revision 1.151  2001/03/27 17:47:45  paulk
;; Eliminate dependency on which package by including the function jde-find-exec and replacing references to the which command with jde-find-exec. Thanks to klaus.berndl@sdm.de for suggesting this change and providing the implementation of jde-find-exec.
;;
;; Revision 1.150  2001/03/23 09:04:06  paulk
