Hi,
As Struts Action classes are Not Thread Safe, in order to make them thread safety, they will be catched , once they are created and then onwards no more Action class instances would be created.
Please correct me if i am worng and please let me know how does this catching happens? i mean whether server will catch them or Struts itself has a built in mechanism to do it?
Thanks.

It's not really caching, it's just that only one is created.

Thread safety has to do with instance variables: since there's only one instance created, actions should either (a) avoid instance variables, and/or (b) make sure that instance variable access is made thread-safe through whatever mechanism.
 
I agree. Here's the link: http://aspose.com/file-tools
