If the client-side application is complaining about not being able to find classes that are part of a framework when run from within Eclipse, it means the the ClasspathClient.txt is missing classpath entries. This file is not automatically maintained by WOLips (yet). Any frameworks that you import into your project must have a corrosponding entry formatted as follows:
monspaced
APPROOT/WebServerResources/Java/MyFramework.jar
