Is there a limit on the number of parameters a URL can have?
No, but there
is a limit on the number of characters, and more params means more characters.
Why not just submit the form to the displayResults.jsp?
I believe the problem is that he wants displayResults.jsp to appear in a new window rather than the same window as the submitting
JSP.
What I believe you can do is to, using a submit handler, open a window using window.open, assign it a name, and use that name in the
target attribute of the form.
In any case, this has ceased to be a JSP question and is now a Javascript question, so I'm going to move this over to the
HTML/Javascript forum for further discussion.
