Page Displays server directory listing

I have just created a page that upon pressing a button submits a form and returns to same to display again teh same contents. After my changes the page instead of showing again the values is showing the directory listing of files in the same location.

I have tested same and I am sure that after pressing teh button, it is setting everythign ready for display, but seems like it is failing to do so.

Does anybody have any idea why such thing is happening.

Without details of how you are navigating back to the page. I'm not sure anyone can say.

Hi thanks for replying. The issue is that first I call the page from another and let the user perform some changes. When pressing the save button, the a form with a "POST" action, calls the same jps page with parameter save to save the details at server level. Form what I have seen this is workign correctly, tha changes performed and the form is re-built at server level, but it seems that Tomcat, the application server I am using, is not sending the re-built page to the browser and everything stops there.

How are you redirecting from your servlet to your web page ?
You may have set the redirection towards a directory.
