Windows XP SP 3 Tomcat 6.0.1 JVM 1.6.0
Must all conflicting classes be sorted out on one instance of Tomcat?
I have learned not to put application jars (classes) in the jre lib,
since they then become common to all applications and if there is a
duplicate, but not exact duplicate, then things crash. What I am
wondering is, are all the classes loaded into the _same_ JVM? Here is
the problem I ran into. Application #1 uses some Quartz scheduling
classes. Application #2 also uses Quartz, but apparently a different
version. Can these applications live on the same Tomcat instance? In
other words if each of the applications has it's own lib, can the
classes overlap? I get the feeling the applications will have to be
sorted out to use the same Quart library. I read the documentation
regarding Class Loader and understand the order in which libraries are
searched, but do the classes end up in one single aggregated JVM memory?
