Subject RE: destroy() is not called when Context is reloaded
Date Wed, 24 Sep 2003 13:46:59 GMT

Howdy,
Then I don't know why destroy() is not being called.  I certainly can't reproduce it, as I
have many servlet in many webapps whose destroy method properly gets called on context reload,
in both tomcat 4.1.x and 5.0.x.  Sorry...
