Problem in using SimpleStream example with jsp

[nick sharma]

Hi
I am facing problems in using the SimpleStream example given in the servlets section for securely getting images on our webpages. i am using the following code in jsp file in order to call the SimpleStream servlet

  rd=request.getRequestDispatcher("/images/"+username+".jpeg");
rd.include(request,response);
  

it gives me the following error when i run the jsp page

java.lang.IllegalStateException: getOutputStream() has already been called for this response
org.apache.catalina.connector.Response.getWriter(Response.java:607)

now i understand that the problem is with the response object that i send from the jsp file which has already called an outputstream. can anyone tell me how i can overcome the problem and get the image on my page.another thing is it possible to place the image using the image tag when i get it using the SimpleStream servlet???

That is the only way to do it. You can't send the image and its page in the same response. The page will request the image using an <img> tag that references the servlet that will serve the image, and only the image.

sorry but i did not understand the reply.are you telling me that the request dispatcher need not be called and that i should give the servlets address as the location of the image???

It sounds from your first post that you are trying to send the image data and the HTML page in the same response. This you cannot do. If that's not what you are doing, you'll need to explain what it is that you are doing a bit more clearly.

thanks i got the reply.that was very stupid of me not to try the image source in the first place
:p

i was trying to get the image from the servlet using the include directive.i know pretty dumb when i should actually use the src variable in the image tag to make life easier sorry for bothering with such a simple thing
