Please use [code] tags [/code] when posting code.
That lot is almost unreadable without them.

Highlight the line of code that the exception is being thrown from as well, so we know where we should be looking.

That exception is thrown because at some point in your code you have already committed the response. Once you do that you cannot then forward to another JSP/Servlet.

In fact:

final java.io.OutputStream os = response.getOutputStream();
os.flush();

Why are you doing that?
As soon as you call flush() you cannot forward bvecause the flush() call (as per the API for getOutputStream()) commits the response.

Hi Tolls ,
Thanks for the reply....
Java Code
final java.io.OutputStream os = response.getOutputStream();
os.flush();
Without this code i got this exception Servlet.service() for servlet jsp threw exception: java.lang.IllegalStateException: getOutputStream() has already been called for this response
i googled about this issue i found the above code that's why i inserted that code.these type of errors i didn't face when i am using jboss 4.2.2.
pls help me how to solve this issue?

[Tolls]

So don't call getOutputStream.
It's not as if you're using it...

You cannot start sending stuff back on the response stream and then forward to a JSP (which is what struts will be doing after the Action has finished).
And the way the response identifies if you;ve started sending things is by marking whether getOutputStream has been called.

[raghu88]

pls see my code i am not calling getOutputStream() anywhere [Remove the above code don't think about it].

i am not clear about this ....change my code and again post

Thanks alot for your reply.

[Tolls]

Line 184 in the code in the first post.
If that code is no longer there then you'll need to give us any new errors/exceptions and where they are being thrown from.

[raghu88]

sorry i was edited my post i didn't found the exact line and i think line 184 is showing an import statement .
dont mind pls tell me where it is exactly?

[Tolls]

Look up there at the first post!
Line 184!

[raghu88]

sorry! can't found pls post the code at line 184
Thanks,
Raghu.

[Tolls]

final java.io.OutputStream os = response.getOutputStream();  // <-- LINE 184
os.flush();

This is in your code in the original post.
Neither line should be there.

[raghu88]

i already post the error if you remove the above 2 lines code...i am getting the following exception....

pls give me the solution its a great help for me.....

So look for anywhere else in your code you are calling getOutputStream.
And I'm not sure why you're setting the response headers etc either.

You have your code...we don't (or the desire to debug all your code for you).
I've explained what that error means, so you should now have the ammunition to go and find the source of the problem.

My problem is i didn't find where getOutputStream() is calling.It is working fine jboss 4.2.2 without any exceptions and problem with jboss 6.1.0

any how thanks for your suggestions.

Maybe JBoss 422 is more forgiving, or there is something else going on that we cannot see here.
Forget about "it works on 422" and simply look for anywhere you are getting the output stream.
Debug the code.
