Exception with displaying image

[Simpson Kumar]

In our requirement we need to display the images on a JSP and these images are stored in database. I can get the image from database uwing rs.getBinaryStream() and I can see the image on the jsp page.
but I get the exceptions on server console

   
java.lang.IllegalStateException: Cannot forward. Response already committed.
 

and on jsp I see two kinds of exception

   
1)Original Exception:
Error Message: Cannot forward. Response already committed.
 
2)Error Page Exception:
Error Message: SRVE0199E: OutputStream already obtained
Error Code: 0
 

what could be the reason? how we can avoid them?
could some one please give me solution.

Oh I forget to attach my servlet code

 ResultSet rs =stmt.executeQuery("select Q1IMG from Q1A1 where Q1A1='qw1'");
        String imgLen="";
        if(rs.next()){
       imgLen = rs.getString(1);  
        }  
      rs =stmt.executeQuery("select Q1IMG from Q1A1 where Q1A1='qw1'");
if(rs.next()) { 
int len = imgLen.length();
        byte [] rb = new byte[len];
        InputStream readImg = rs.getBinaryStream(1);
        int index=readImg.read(rb, 0, len);  
        response.getOutputStream().write(rb);
        response.getOutputStream().flush();
}

I got it..

My solution is don't ever use Struts while streaming images from database....

I just created a Servlet and copied the same code from Struts Action class to this Servlet and worked. I don't know what is the exact issue behind Struts action and I will find it soon. However, I got the solution thats it.
