I don't have a "common/endorsed" folder. Is this specific to more
recent versions of Tomcat ? I'll create it anyway.
Also, I've got a jaxp.jar and jaxp-api.jar file but what is
jaxp-ri.jar ?
I'd still like to keep jaxp installed on my machine for other
java applications. This won't affect Tomcat at all, will it ?
Thank you again.
