WebLogic throws java.lang.ClassNotFoundException when I compile and deploy a change in my eclipse maven project

I just started using Maven with eclipse and deployed my application to WebLogic.

When I do a clean install for the first time, my Maven project builds and deploys successfully.

After that, when I make any change to the source code or jsps, I do a pre-clean install to update the project. Now, everytime I do pre-clean install and restart WebLogic I get the following exception:

java.lang.ClassNotFoundException:
at weblogic.utils.classloaders.GenericClassLoader.findLocalClass(GenericClassLoader.java:283)
at weblogic.utils.classloaders.GenericClassLoader.findClass(GenericClassLoader.java:256)
at weblogic.utils.classloaders.ChangeAwareClassLoader.findClass(ChangeAwareClassLoader.java:54)
at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at java.lang.ClassLoader.loadClass(ClassLoader.java:251)

I did some researches and for some reasons, No one complained about that error before.

Any suggestion what can开发者_Go百科 be the problem ?

This only occurs after I make a change and run "pre-clean install" from within eclipse.

How is it deployed exactly? Do you use WTP and the Weblogic adapter? Do you use m2eclipse?

after that, when I make any change to the source code or jsps.. I do a pre-clean install to update the project.

Why do you run pre-clean? Do you have anything special bound to pre-clean (there is nothing bound to this phase by default). What is the expected result?

Now, everytime I do pre-clean install and restart weblogic I get the following exception:

What is FeatureForm, it it yours? Could this be something you removed that is still referenced by a temporary file generated by WebLogic (e.g. a Servlet generated for a JSP). Does the problem happen with this class only? Did you try to remove the work dir of WebLogic?

Any suggestion what can be the problem?

I'm not sure I'll be able to answer this question but you need to provide more details about your context and the way you use tools.
