I've had some troubles to cleanly undeploy an hibernate-powered webapp (either from tomcat manager application or ant-task)

When the application already had any hibernate activity, the ehcache.jar remains in .../webapps/myapp/lib

I did'nt find any information on this behaviour, but I think that the tomcat server via the configured connection pooling has loaded the ehcache.jar and therefore it cannot be deleted ...

any hints are welcome, because stoping tomcat, removing files and directories via script and starting tomcat get's annoying ... ;)

I'm using:

Tomcat version: 5.5.7 (stable) on WinXP (for development)
Hibernate version: 2.1.8
Name and version of the database you are using: MySQL 4.1.10

thx in advance
