tools.jar & JCompiler

Submitted by rharlos on Wednesday, 7 April, 2004 - 21:50

I'm a relatively new JEdit user and I enjoy it very much. One point I'm struggling with is the visibility of tools.jar for the JCompiler plug-in.

I know I can just copy it into the jedit/jars folder (because I did this on a friends laptop just to get it working) but i really, REALLY want to solve this problem using JAVA_HOME and/or CLASSPATH.

When I installed the SDK (1.4.02), I opted to allow it to install the public JRE as well (was this my bad?). Without having set any environment variables (did I mention I'm using Windows XP Pro?), the plug-in reports that it can't find tools.jar ... that my java.home is the public install (c:\program files\java\j2re1.4.2_04\bin) ... the the tools.jar file is usually found (relative to java.home) in ..\lib, so...

I've tried creating a CLASSPATH env var that points specifically to the tools.jar in the SDK/lib directory... I've tried adding a JAVA_HOME env var that points to the SDK's \bin directory, and to the actual root/home directory... none of these things seems to work.

I feel as if I'm going to HAVE to copy tools.jar into jedit/jar in order to get this to work but I can't help but wonder if I'm just overlooking some simple step/idea that would allow me to get this working WITHOUT having to do the copy.

Any help much appreciated!

Simple and robust solution to running tools.jar

If you use the "shortcut" approach, on Win98 you get an MS-DOS window that kills jEdit when you close it - not good.

A better solution is to run jar files using the SDK rather than the JRE:
1. Open My Documents.
2. Click View > Folder Options.
3. Click on the File Types tab.
4. Select the Executable Jar File from Registered File Types.
5. Click Edit button.
6. Select "open" from Actions.
7. Click Edit button.
8. Change the "application used" from

"C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe" -jar "%1" %*

to

"C:\j2sdk1.4.2_04\bin\javaw.exe" -jar "%1" %*

Obviously you'll have to check that the paths match those on your computer.

9. Click OK or Close on the various dialogue boxes.

Now when you double-click the jedit.jar file (or any shortcut link to it), JCompiler and other tools will work fine.

Enjoy.

You could try starting jEdit

You could try starting jEdit with a JDK JVM like so:

C:\j2sdk1.4.2_02\bin\java -jar jedit.jar

If you're using jEditLauncher, you'd need to change its configuration.
