[Trinidad] NPE from Googlebot user agent
Hello,
The web app I'm using Trinidad on needs to be indexed by Google
correctly and the Googlebot has just started crawling it. I've noticed
that every time the Googlebot makes a request to the web app a NPE is
generated and I don't want Google indexing the stack trace error.
I've been testing our web app today using the latest nightly build of
Trinidad & Firefox's User Agent Switcher extension along with the
following user agent:
Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
The stack trace generated on the first request is:
Sep 8, 2008 12:38:05 PM com.sun.facelets.FaceletViewHandler handleRenderException

How can I stop a 500 error page being shown to requests made by the Googlebot?

Re: [Trinidad] NPE from Googlebot user agent
Posted by Jonathan Bullock <jo...@fugro-data.com>.
Hi Matthias,
Thanks for confirming the situation for me. Is anyone working on a fix
at the moment? I might try to look into it if no one already is?
I've created a jsp index page so I can detect the Googlebot user-agent
and create content for Google to index to get round the bug for now.

The stacktracec was here:
https://issues.apache.org/jira/browse/TRINIDAD-1146
This bug is different, and already know... introduced when the "versioning"

https://issues.apache.org/jira/browse/TRINIDAD-1109
So, yeah this is unfortunatly a known bug.
