can I move struts.jar?

[Qiqi Dong]

I have a problem need help.

I have many webapps. Everytime I update struts.jar, I have to do it for
every WEB-INFs, it's . I tried to place the struts.jar in Tomcat's lib, got
the following. Is there a way to have just one copy of struts.jar somewhere
for all the applications?
