NullPointerException in Tomcat
I am getting a NullPointerException, and the stack trace says it is down in
the bowels of Tomcat somewhere. Can anyone give me any ideas of what might
be wrong?
Thanks
Here is the stack trace:

It's more a Netbeans error than a Tomcat error. I'm sure you will
receive a better answer in the Netbeans users mailling list.
Sorry :-(

The Netbeans team have added listener to Tomcat. The exception is
occuring when Tomcat call those listeners. So you just have to read
Netbeans code ;-)....Can you give more information on how you produce
the error. I suspect a bug in your code....

RE: NullPointerException in Tomcat
Posted by Bradley Ward <bw...@riverdrop.com>.
I see that it is in the netbeans level, but I was hoping someone in the
Tomcat world would know what is going on. None of my modules are in the call
stack; it is all within some internal Tomcat call. Since there is none of
my code involved, it would appear that Tomcat is calling netbeans in some
invalid manner.
Does this mean in order to work with Tomcat I will have to diagnose Tomcat
source code AND Netbeans also? I surely hope not...

RE: NullPointerException in Tomcat
Posted by Bradley Ward <bw...@riverdrop.com>.
When you mentioned the filters "in my web app", I thought "but I don't use
any filters". Heck, I don't even know for sure what they are. But (and
this is a big but), I am using the Tomcat that comes bundled with the Sun
One IDE, and IT was putting both a filter and a valve into the server.xml
file. I removed these and have been able to proceed. So it would assume
there is some sort of problem with the Sun One IDE in this regard.
Thanks!

The NPE is occurring here, not inside Tomcat. Check at line 979 of this
class.
