Hello
Do you need this sequence to be full JSP ?? Because JavaScript librairies exist to let you directly sort tables. Thus, no page reload is needed.

I did it totally differentlty. I had a report generate action and generic form `ViewReport' and `ViewReportForm' respectively. The business report action form was stored in the SESSION scope. This generated a report. My action form stored a list of rows as a Java collection in a nested attribue "rows". I rendered the report using HTML Tables in a bog standard JSP. For each column I designed two up and down arrow gifs and generated two html link using the gifs I wrote a new action `SortReport' and form `SortReportForm' with two attributes "column" and "order" (ascending and descending). The sort action just sorted the existing rows retrieved from the `ViewReportForm' (action form in the session) and forward dispatches back to the report jsp. Of course I realised, back then, that I could move the actual sorting in to the `SortReport' in to `ViewReport' action, but I had a brainstorm, I could write the SortReport to sort any sort of data stored in rows. However I never got around to figuring out the code to do it. It involved a lot of `String' to actual Java Object instantiation ie reflection.
