Right, that's what I figured. The example is correct, but it's just a fragment and assumes the rest of your page is correct. Without the form tag, I can all but guarentee that your page IS NOT correct.
This is why I suggested using the demo source as a starting point. The problem here is that we told you multiple times what to try. Myself and others said to add the tr;form and you argued that it wasn't needed. I then suggested ways to debug your current JSP and you told me that you didn't need help in debugging you jus wanted it to work. Finally, I even asked you look at the demo source which has a real working example, and you tell me that you shouldn't have to do that.. At this point, I'm not sure what other help you expect?
