68 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:

Lazy Lazarus 21.1 70 {{noformat}}
71 APPROOT/WebServerResources/Java/MyFramework.jar
72 {{/noformat}}
David Avendasora 18.1 73
Lazy Lazarus 21.1 74 {{note title="WOROOT path"}}
David Avendasora 18.1 75 Don't use the WOROOT path of the framework (WOROOT/Library/Frameworks/MyFramework.framework/WebServerResources/Java/MyFramework.jar)
76 because this is only valid for the core WebObjects frameworks. Any other frameworks (yours, Wonder, etc) need to be located in the APPROOT.

80 **Deployment**
81
82 When deploying keep in mind you must not use the full sized WebObjects frameworks/jar files. These are meant for the server side.
83
84 For client deployment always use the jar files located within the ##WebServerResources## directory of the frameworks. This will save from quite some errors.
