Hi,

I have a Tomcat 5.0 installed on an XP machine, but I have trouble to run a web application. It might be the classpath too long, but I'm not so sure. Error from the log:

java.io.IOException: CreateProcess: javac.exe -classpath "C:\Program Files\Documentum\shared\dfc.jar;C:\Program Files\Documentum\shared\dfcbase.jar;C:\Program Files\Documentum\shared\xtrim-api.jar;C:\Program Files\Documentum\shared\All-MB.jar;C:\Program Files\Documentum\shared\bsf.jar;C:\Program Files\Documentum\shared\log4j.jar;C:\Program Files\Documentum\shared\xalan.jar;C:\Program Files\Documentum\shared\xml-apis.jar;C:\Program Files\Documentum\shared\workflow.jar;C:\Program Files\Documentum\shared\subscription.jar;C:\Program Files\Documentum\shared\xforms.jar;C:\Program Files\Documentum\shared\XformsCommon.jar;C:\Program Files\Documentum\shared\commons-jxpath-1.1.jar;C:\Program Files\Documentum\shared\castor-0.9.5.2.jar;C:\Program Files\Documentum\shared\ci.jar;C:\Program Files\Documentum\shared\collaboration.jar;C:\Program Files\Documentum\shared\ctsTransform.jar;C:\Program Files\Documentum\shared\ctsTransformImpl.jar;C:\Program Files\Documentum\shared\bpmutil.jar;C:\Program Files\Documentum\shared\messageService.jar;C:\Prog”
      at java.lang.Win32Process.create(Native Method)
      at java.lang.Win32Process.<init>(Unknown Source)
...

Since I ddi not see all the jar files listed in classpath, I doubt it's related to classpath. But how can we shorten the classpath? It's big application.

Thanks a lot!

Hi

There is one manual way to reduce the classpath lengh.

It is some what tricky.

Steps:

List what are all the jar files in your classpath.(write down on paper or any text file)

Use any Graphical user interface to create one final jar file with all jar's.

you can create jar with jar -cvf also  but you need to made changes to MANIFEST.MF file to make internal jar's available. Its a lenghty process.

So i suggest you to use any free ware to create big jar file with all your small jar files like xalan.jar,xml-apis.jar ect..

after that add that generated jar file to your classpath and remove all above listed jar fiels from class path.

Follwing link is one GUI based jar designer. Make use of that that will solve your problem

Hope this will help:)
