Hi Dirk: Sounds like you're talking about client-side issues here. If you're just trying to populate form-fields with values from a child window (i.e. popup), use javascript to try something like this in the popup:
function updateParent(){ popUpValue = document.getElementById("whateverThePopupFormFieldIdIs").value; parentField = opener.document.getElementById("whateverTheParentFormFieldIdIs"); parentField.value = popUpValue; close(); Then set the form tag's onSubmit="updateParent()" or set the submit button's onclick="updateParent()" in the popup window. Make sure you set the required fields' id properties. Now if what you require is some processing of the popup's data by the server, then a subsequent update of the parent... Submit the popup form to whatever Action you require, then map the successful completion of the Action to a simple html page or jsp, which need only contain the following script: function updateParent(){ opener.location.reload(true) close(); } and set the body tag's onLoad="updateParent()". If you're talking about all server-side manipulation, Mark Lowe's answer was just fine. Hope that helps.
