Hi Dave, Thanks for your reply. Sorry, I was away a few days for the midsummer holidays (here in Sweden).
I couldn't find any instructions regarding being allowed to attach files to such mails. So I didn't take the risk. Also copying the content of the files here was probably not proper either, was it? Please tell me if it is possible to attach files and I'll send you the files. Here is some more explanations about the issue: In my HellowWorldAction.java I used a private static variable helloCount with belonging get/set methods. As you see in the examples it returned empty in the jsp when invoked inside <p> tags and correct value when outside the tags, while the static variable for DAY-OF-WEEK could return its value when invoked inside <p> tags. Just in order to test the situation about static variables in actions, I defined an instance variable instanceCount set to the value of helloCount in the execute method, and with its own get/set methods. This returned its value even inside <p> tags as expected. So, my question was: Why a difference between two static variables in Java? also the reason to the difference between static and instance variables in the same action class?
