Subject RE: Tomcat 7.0.50 on IBM i series - System i V7R1 - Installation errors
Date Tue, 04 Feb 2014 03:08:12 GMT
Hi Konstantin/Daniel,

We are using Java 1.6.  The gnu.xml has not been installed separately. It must have been a
part of the Tomcat installation.

The XML parser is whatever comes default with Tomcat.  
  We did a copy of the working copy of Tomcat (7.0.50) from the Development box to the production
box.  Both are running on the same release of the software V7R1 and the patches are also similar
as they get applied simultaneously.
The only difference in libraries is a library provided by Robot on the  production box which
is RBTSYSLIB.LIB. 

Not sure what is happening on the production box with Tomcat as we are still not too familiar
with the startup requirements of Tomcat. We have not even copied our application.  All indications
seem to be a JVM and Java or path problem like you indicated but not sure how to get to the
bottom of the problem. Is there a verbose way of starting up Tomcat where we can exactly see
where it gets stuck up other than the log file. We are not getting much information on this
log file at all.


Regards

Shekar

"gnu.xml" package?!

What JVM and XML parser are you using?

The above in 7.0.50 is usually caused by missing jsp-api.jar.
