As I recall, I think the first thing you need to do is ensure in your weblogic.xml descriptor the following value is set
So that the java src files for the jsps are saved.
I can't remember exactly where it saves them, but somewhere under user_projects/domains/yourdomain/servers/yourserver/tmp/_WL_user/yourappname/
seems to ring a bell.
Look for a sub-dir named jsp_servlet a a dir or two below that,
oh almost forgot, you can specify keepgenerated at the app config in the WL10 console as well.
And, the root level package can be defined as well (aka directory), just defaults to jsp_servlet I think.
