Opening new JSP page with parameters of parent page.

[Zak Nixon]

<nods head>
I have two pages, one called Search.jsp and DisplayResults.jsp.
Search.jsp collects all the information that a user wants to search
for, and after they press a 'search' button, the DisplayResults.jsp
displays the search results. This means that all of the data that
I collected within the search page needs to be sent to the
results page.
I have an initial idea, does it work?
window.open("DisplayResults.jsp?....(all of the parameters collected within Search.jsp");
is there a simpler way of sending all of the parameter collected within
search.jsp to displayresults.jsp?
Thanks

Since you can only stuff so much on the URL, you could run into a problem if the list of params gets long.

[Zak Nixon]

Is there a limit on the number of parameters a URL can have?
Also, do you have a possible solution to my problem?
THanks

You are most likely collecting the user information with a FORM? Why not just submit the form to the displayResults.jsp?
Example:

<FORM name="fooForm" action="displayResults.jsp" method="post">
  
  <%-- all your input fields --%>
  
</FORM>  

Then you just have a button which will submit the form. Ideally, you'd want to submit the form to a Servlet, which grabs the results from the database, then forwards these results to the proper page for display.

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.

Ok,
I have the following:

 function test(){
   var resultsWin = window.open("http://localhost:8100/DisplaySearchResults.jsp");
document.searchForm.target = "resultsWin";
}

 

My form is on a page called SearchRecords.jsp, and my form is called
searchForm.
Whenever the submit button is pressed, test() runs successfully, but
pops up DisplayResults.jsp (no params passed) and another page
which is my SearchRecords.jsp page with all the parameters.
Can someone lead me in the right direction?
Thanks
