loadClass method, and it is not reporting anything, and to the best of
my knowledge, an error should terminate the JVM right?
No, it shouldn't. You can catch errors also by catching Throwable
instead of Exception.
Thanks very much for this bit of advice, as it turns out it was throwing
My attempts to abate this error are proving quite fruitless. So I was
wondering... what is the preferred method to programatically reload a
class in Tomcat? I've searched the web but I am stuck.
Thanks

You can simply set reloadable=true for your Context and Tomcat will
monitor your classes and reload the webapp (not just the class) as
needed. You can also programmatically invoke the Manager webapp and use
its reload feature.
What if these classes aren't located in the Tomcat directory?

Why must I write a custom Loader, isn't URLClassLoader already suited
for this task? What is it about URLClassLoader that makes it
incompatable with Tomcat?
Then you have to write your own custom
I apologize for not being clear the first time. My class loading scheme
works by first loading classes with a URLClassLoader and then when the
program wants to reload them, it creates a new URLClassLoader whose
parent is the first URLClassLoader, thus staying within the delegation

Hi,
If you get a thread dump of the JVM while it's hanging, what does it
show?
The URLClassLoader is intended for use within Tomcat. It's nice that
you have a program using outside Tomcat, but it's not that meaningful
for comparison testing. The ClassLoading scheme and hierarchy inside a

I know this is naive of me, but how does one get a thread dump of the

different to use URLClassLoader under Tomcat than I do in a console

I was creating
