Tomcat 3.3.1 - Tomcat 4.1.x (Xerces), WebAppClassloader debug level
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?

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? What is your third party software that uses xerces-1.4.4? This solution certainly works for most cases, but you may run into trouble if other apps expect Xerces2.

I'm just wondering if Tomcat itself could run into a problem when I replace the xerces version. Yep, it should be able to. Further, it's documented in the classloader-howo paper that I can deploy my own xerces version into web-inf\lib. But that doesn't work. Probably Tomcat loads some classes from xerces 2.x (common/endorsed) and some from web-inf\lib. Any documentation that says this is dead wrong. Ask any Tomcat developer and they will tell you this. I'm not sure why the docs haven't been updated, but you shouldn't put Xerces or any endorsed packages in WEB-INF/lib. The latter violate the Sun classloading spec and the former is just too problematic to support. Weird classloader stuff that you don't want to mess with. Putting these packages in a parent classloader including common/endorsed, common/lib, and shared/lib is the correct way to do things. Do you know how I can increase the debug level of the WebAppClassloader? I'm interested in which classes are loaded from which classloader. Not sure. Hopefully someone else will have more info about this.
