Jakarta Tomcat Manager - Problem with redeploy war file

[June Moore]

Hi,

We had a problem where Tomcat Manager is not able to (re)deploy a
war file after a manager remove. The problem was traced to the
situation when a servlet (or tomcat) has one or more of the servlet's
jar libs locked (in use). If this is the case, tomcat manager is not
able to delete it during the remove and any subsequent deploy fails
because the locked jar cannot be replaced by the manager.

We were not able to discover a method to prevent the jar from being
locked or a method to unlock the jar other than restarting tomcat (an
undesirable solution) and then deleting it by hand.

Any suggestions on how to resolve this problem?

Much appreciated.....
June.
