Hello,
Don't know if this will help you, but I will throw some ideas.
I ran into a similar "locking" problem a few months ago - not with Struts.jar
but some other file.
Are you using ANT for auto deploying? Is Struts.jar in your classpath at
the time of auto deploying? How about the local DTDs for struts config
and web.xml - are they in the classpath? If they are then - humor me -
remove them from your classpath and see what happens.
Anyway, that's all I can come up with right now - from the department of
useless ideas :) :)
HTH!
