Sorry Rita my explaination was a little brief. I am using Tomcat 4.0.4 on Debian with JDK 1.3.1 and will be upgrading to JDK 1.4 soon.
I have searched the web for an answer on this but no one seems to have posted any information regarding setting up a custom class loader in Tomcat. I have looked at the loader.html page on the jakarta site; http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/loader.html And it explains how this should be done. However when I restart tomcat it appears that my loader does not get executed. I have based this on the fact that my execution code that includes writing to a file in the constructor does not get executed. I only get an error when I also include a class which extends WebappLoader for the loader using the 'className' attribute in my <Loader> tag. Other than this Tomcat compiles and runs successfully, which makes me wonder whether there is another way to test whether my ClassLoader is being executed or not.
