     strOffset=request.getParameter("pagination");
     else
    strOffset ="0";
    String strLength = "2";
    int increment = Integer.parseInt(strOffset) + Integer.parseInt(strLength)
;
    String strIncOffset = String.valueOf(increment);
      ArrayList list  =(ArrayList)request.getAttribute("pattern");
 int size= list.size();

    if((Integer.parseInt(strIncOffset)>= size))
     strIncOffset ="0";

One reason you may not be getting an answer is that
this has nothing to do with Struts.

(The following is my opinion and probably does not
reflect the views of the rest of the Struts mailing
list.)

I started to look at the code, but it was too weird
for me--it would not have survived even the most
cursory of code reviews. That made me even less likely
to want to answer the question.

What I would suggest doing (besides cleaning up the
code) is, on paper, write down a few test cases,
focusing on the edge case which is giving you problems
at the moment.

Build a truth table using your values and the logical
conditions you have and see why they might be failing.
If I don't have anything else to do at work today
perhaps I'll suck it up and take another look at it
and you can buy me a Kingfisher.
