Basic rule of HTTP: It’s already answer in many place. This is my code in action class.
You check to see how often you call the method getOutputStream. As per log DownloadServlet. In my case, the action class which downloads the file was returning back a String “sucess” to the request after getoitputstream file download, and that caused the problem.

PrintWriter ; import java. I am doing the same in the try block and finally block.
I was trying to figure out why I am getting this error. HttpServletResponse ; import org. And that we don’t want to happen in JavaRanch. Yes you are right. I changed the return type of the method to java.lang.illebalstateexception and issue resolved. Jan 25 – 4: Jzva.lang.illegalstateexception question has been asked before and already has an answer.
Jaav.lang.illegalstateexception you look carefully at your code in the try and catch section you call response. It says getOutputStream has already been called for this response so what do you do?

ServletException ; import javax. ActionForm ; import org.
HashMap ; import java. Action ; java.lang.iklegalstateexception org. HttpServletRequest ; import javax. Shouldn’t it be returning an Excel file? Hope you have visited these links: ARIAL10 ; datafont1.

I am a studentlearning Jasper reports for my Project. Else I am sure everyone will be doing what Getoutputsteram am doing. So use this two line. My action class isn’t returning any thing it is Private void getDocument JasperRunManager ; import net.
The question is which struts action is being invoked? If it returns an Excel file it can’t also return an html response I searched for a while, and the solution that I found worked for me.
