This example was greatly inspired by the Stripes and jQuery AJAX Forms article from Freddy Daoud, but with some nice improvements

Last week I was working on a new Stripes / AJAX example. It involves having a table listing entities, being the last row of the table a form for adding new ones. The form gets submitted via AJAX, using jQuery, and the response is validated in order to check if the HTTP session is still valid.

If everything is OK, the list is refreshed and a success message appears. On the other hand, if validation errors occur, the list is refreshed and an error message appears. Also, if the user’s session has expired on the server, an alert is shown to inform the user that his session is invalid, and the page is reloaded so the user can login once more.

After googling a bit for error “java.lang.OutOfMemoryError: PermGen space” I found many sites talking about that problem. Some tried passing command line arguments to the JVM or changing the size of the PermGen space, others end up recommending using a VM from BEA or IBM, all without success. But after a closer look at their comments I ended up at Frank Kieviet blog. Frank explains what really is a PermGen error…

Coding conventions are rules that computer programmers follow to ensure that their source code is easy to read and maintain. Why is that important? Sun Microsystems provides the following rationale for the Java Programming Language: Code conventions are important to programmers for a number of reasons: 80% of the lifetime cost of a piece of software goes to maintenance. Hardly any software is maintained for its whole life by the original author.…
