java.lang.NoClassDefFoundError problem

289 Views

Hi everyone

I have developed a login module class. In this class I call a webservice, so I have imported some external classes. And I export the jar file, create a library project and deploy the library project on to the server following the help document. After that I add my login module into the ticket template. When I want to logon to the portal, I always meet the "java.lang.NoClassDefFoundError: javax/xml/rpc/ServiceException" exception after I inputed the id and password.

I have tried many ways. For example in my login module project, I import the jars I used into my project and in build path choose "add jar..." not "add external jar...". Then export my project including all the jars I used. I also try to copy all the jars I used onto the server, under the <java home>/jre/lib/ext directory. I also have changed the MANIFEST.MF file of my project by adding the classpath to it. But nothing helps me.

So do you have any more method to solve my problem?

Thanks
