Re: Class loader problem with Tomcat 4.1.12 ...

[Jean-Francois Arcand]

Well, his bug is more related to where the xerces.jar should go, I think. Under 4.1.12, place your jar file under the common/endorsed folder. Tomcat uses that directory at startup: -Djava.endorsed.dirs. More info at:

Yes, I did and it got answered here :-)

By default, the settings in $CATALINA_HOME/conf/catalina.policy
exclude the local directories from the Class Loader hierarchy,
for security reasons. You have to grant EACH codebase that
is a WEB-INF subdirectory explicit permissions (use other
entries in that file as a model) to execute java code.

I've opened a documentation bug suggesting that this be
documented in the class loader HOWTO.

Hi,

I have developed a servlet that works with a specific version of 'xerces.jar' and want to ensure that the class loaded picks this version of xerces.jar when the servlet is invoked.

The Class Loader INFO note that explains how the class loader works in Tomcat 4 says that the local repositories (WEB-INF/classes & WEB-INF/lib of the web application) are always looked first. This works fine with Tomcat 4.0.5. However it is apparently not working with the latest Tomcat build 4.1.12.

Anyone faced this problem ? I would appreciate your response.

thanks
vijay
