Hi,
Look at Java Service Wrapper project. I think you can extend there
logging trigger filter API.
http://wrapper.tanukisoftware.org/doc/english/prop-filter-x-n.html
As you detect the OME then you can use the jkstatus mod_jk interface
to deactivate the worker from list.
http://tomcat.apache.org/connectors-doc/reference/status.html
I don't see that a real jvm hook exists for OME's.
Please, use the user list for those questions first.
Thanks
Peter

hi there everyone,
I'm new to the list.
I would like mod_jk to detect when the Tomcat JVM got into an
OutOfMemoryException
so that mod_jk avoid to forward request to that Tomcat.
If I'm not wrong, it could happen that the mod_jk balancer forward
a request to a JVM in such a state,
since the mod_jk isn't able to recognize as crashed a Tomcat in
OutOfMemory.
I would like to write a patch for the mod_jk to add such feature,
but I don't know the code at all,
could someone get me introduced to it?
Any suggestions? Mini how-to? Support?
I would appreciate them so much and I promise to try any attempt to
add this feature,
if I can figure out how things work in the mod_jk core and in its
load_balancer.
