The bean accepts a "type" attribute that you can use to set the fully qualified Java classname of the actual bean. If you don't specify it, the corresponding bean type is looked up based on the corresponding action mapping -- at least with recent nightly versions. > Keep on digging, > Scott > Craig

RE: Problem finding classes after forward (resend)
Ummm, I'm not using WebLogic ;-) I've figured out some of the problem. I can't do a of my formBean because (in ActionServlet.processActionForm() ) the bean is put into the request as an ActionForm, not as my class. So I can cast it to ActionForm, but not to my class (com.propel.webapp.actions.AddressForm). I can probably figure out a way around that (maybe by using the bean tags?), but the other problem I'm having is still confusing me Keep on digging, Scott > -Original Message- > From: Abraham Kang [mailto:[EMAIL PROTECTED]] > Sent: Thursday, April 05, 2001 11:07 AM > To: [EMAIL PROTECTED] > Subject: RE: Problem finding classes after forward (resend) > > > Hi Scott, > > This might be a problem with WebLogic.

RE: Problem finding classes after forward (resend)
Hi Scott,
This might be a problem with WebLogic. I think this problem is prevelant in
WebLogic 5.1. You might want to do a search on ClassCastException in the
WebLogic 5.1 docs and newsgroups.
