First, when posting more than a line or two of your code, it is a good idea to wrap the code in UBB CODE tags. This will preserve your indenting and make it much easier to read. If it's easier to read, more people will read it which means you are more likely to get help.
As to your question, if you want to the user to be able to fill the form out multiple times within one session, you will want to create a method that will generate a new userBean for each form submission and add those beans to a list. You can then use JSTL to iterate through the list for display purposes.
