Subject Antwort: Tomcat 3.3.1 -> Tomcat 4.1.x (Xerces), WebAppClassloader debug level
Date Tue, 12 Aug 2003 04:52:39 GMT




It did run well with Tomcat 3.3.1
I found out that the included xerces version of this third party software
uses xerces 1.4.x. So, I removed the xerces jars in common/endorsed and put
the version 1.4.4 in there. Then, my application works again.
Is that the correct way to solve my problem or am I running in other
problems now?

Hi

I've got a big problem running my web application inside Tomcat 4.1. I'm
using a third party software in my servlet implementation. This third-party
jar contains xerces classes. But my web application is not running anymore
(VerifyError).

I don't know if there is a versioning conflict with Xerces. So I wanted to
increase the debug level of the webappclassloader to see whether some
classes from Xerces are loaded through the parent classloader and some by
the webappclassloader.
<Context path="/k__offerten" docBase="k__offerten" debug="4"
                 reloadable="true" crossContext="true">

                 <Logger className="org.apache.catalina.logger.FileLogger"
                                  prefix="kloff_log." suffix=".txt"
              timestamp="true" debug="4"/>

      </Context>


But there are no logging information. How can I log the webappclassloader
logevents?

Does anybody have an idea how to solve my xerces problem?

Regards
Oliver
