  • Thread-topic: Blank page after deploy on Ubuntu
Hi,

There is nothing in the page, no code after "View Code". No exception
throw. No R-R loop
I'm just wondering something wrong in my apache config, but don't know
what's wrong...

I did search in the archive list, somebody said might be something wrong
in the classpath, so that's why I post them in the email.
I could n't see anything wrong, and app is launched.

Help! maybe somebody in deployment list?

Your app is throwing an exception very early or very late in the R-R
loop.  Override dispatchRequest in Application and performAction in
DirectAction to catch and log Throwable.  That should show what is
failing.  You _will_ need to have the Output Path configured for the
application.
