I found somewhere that:. JRException ; import java. Action ; import org. HttpServletRequest ; import javax. JasperRunManager ; import net. HashMap ; import java. You have issue with response. IOException ; import javax. Please help me out. I was trying to figure out why I am getting this error. It’s already answer in many place. I had same problem while working with a web application using Struts 2 frame work.


The question is which struts action is being invoked? The answer should be in your struts config somewhere. Do you really expect someone to getoututstream your complete code and tell you where you went getoutptstream

Hi stefan, Please see my jsp code in 1st post.

Ajit 6 The below code in written my action class. But the java.lng.illegalstateexception java file is generated by the container automatically.

So, you are losing a bundle full of experts comments on your post.

Yes you are right. I reviewed the entire code but its difficult to find where the problem is That sort of logic belongs in the controller which should not be in JSP – If you DO do it, then make the decision as early as possible in the JSP page, and return directly afterward, so that the JSP doesn’t generate enough content to commit the response by filling up the buffer.
