Hi all,

I am running an application and the error that I get I think has little
to do with my application. The error is as follows:

java.lang.NullPointerException

I am using a Linux machine and java 1.4.2. My application deals with
XML extensively. Hence the SAXException in the stack trace above.

Thanks in advance for any help

regards,

ASD

Can you try another version of Java (e.g. Sun's or Blackdown's JDK) and
see what happens?

Hello again.

This is now the second time* I have seen you
multi-post to these groups.  

* ..now I notice a third.

Do you understand what multi-posting is?

[ Please note that while I usually make a point of leaving
at least one thread with no "please don't multi-post" message
on it, if it is something you intend doing habitually, I
will find it necessary to warn *all* potentianl posters of the
time you are wasting. ]
