Displaying results of a jsp provider in it's channel not in a new page

I have a jsp provider with a form that sorts the results of a database query. However when I submit the form to sort the results, they are displayed in a new page. How can I make it refresh the channel in the existing desktop? I intend to do this in a jsp not a Servlet. Please include examples if you have any.

Thanks!

This is the form that I am using:

<FORM NAME="myForm" ACTION="/DesktopServlet" METHOD="get">

<INPUT type="hidden" name="action" value="content">

<INPUT type="hidden" name="provider" value="protonSampleJSP">

<select name="sort">

<option value="CATEGORY_ID" SELECTED>Category</option>

<option value="TYPE_ID">Document Type</option>

<option value="TITLE">Document Title</option>

</select>

<input type="submit" name="submit" value="Sort">

</FORM>

Thanks
