Hmm. At worst, if your app is configured (and it simply doesn't recognize your tile) you should get either a 404 or a "white screen of death". With the trace provided, I would suspect some other unrelated problem in LogonAction.execute() such as a null form or something similar. Walk through the action with a debugger and see where the error really occurs.

See > http://jakarta.apache.org/struts/api/org/apache/struts/tiles/a ctions/Definit ionDispatcherAction.html Otherwise you end up with a basic link to a document with your tile name, which if you stop and think about it makes sense. So you'll end up with a 404. > This didn't seem to work and I had to use: > > <html:link href="/ToExtract" > > > and: > > <action path="/ToExtract" forward="app.extractDefinition" /> That'll work, too. You also can't declare a global forward to a tile and expect to have it work correctly, though, so don't try it. =) > I have read a lot but haven't found a clear outline to using > defintions in Struts. Yeah, I noticed that, too. But I managed to figure it out--and it looks like you're halfway there. =) David Hibbs, ACS Staff Programmer / Analyst American National Insurance Company --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
