I'm getting IllegalStateException from Tomcat server, when I try to save a JSP's data in EXCEL. IllegalStateException can occur in any of the following condition:
sendRedirect().Other than this, is there any causes for IllegalStateException?
My code:
response.sendRedirect(response.encodeRedirectURL(request.getRequestURI() + "?saveToFile=true&action=" + ReportsManager.ACTION_SAVE_AS_XLS + "&saveFileName=" + saveFileName + "&returnPage=" + StringFunctions.encodeUrlParameter(returnPage)));
return;
I'm getting IllegalStateException at sendRedirect().
Also if there are only few records (say 100 rows) in JSP, then there is no error in saving as Excel. If there is 1000 records, then I'm getting IllegalStateException.

If I set page buffer size, then it worlks fine for 1000 records. But if it reaches 2000 records, then again I'm getting issue.
<%@ page buffer = "2048kb" autoFlush = "true" %>
The Documentation states:
sendRedirect Throws: IllegalStateException - if this response has already been committed
Since disabling the maxPostSize does not solve the problem (according to OP comments) it seems that at an earlier point the responce is beeing commited.
You can verify this by checking the isCommited flag.
