Sorry, I looked at the JSP 2.0 specs, I tried to invoke it on my tag files, but still I don't understand how jsp:invoke works. Is there anyone who can explain this to me?

Thanks.

I visited the link but still I couldn't have an example to run.

I wrote the Tag file as follows:

I don't know much about jsp:invoke and I am taking the exam tomorrow! Anyway, I found this example in the web.See if this makes sense.
