In a web application running under Tomcat, I have defined a filter in the web.xml
file. The filter is pointing to a class that is packed in a jar-file, and the jar-file
is kept in the $CATALINA_HOME/shared/lib directory.
In Tomcat 4.1.x the application is working without any problems. When trying to run
the same application under Tomcat 5.0.28 a java.lang.ClassNotFoundException is thrown.
If the jar-file is placed in $CATALINA_HOME/common/lib, then the class is found and
the application runs without problem.
The same issue appears when using Listeners in the web.xml file.
I have also tried the same setup with 5.0.27 which leads to the same result.
What is it that has changed between 4.1x and 5.0.x, in regards to classloading, in
order to cause this problem ?
Any help in understanding this problem is appreciated.
Regards
Erik
