Returning image and setting http headers

[sshetty]

Hi,

We have an existing system that uses servlets. We are replacing the system to use JBoss ESB.

One of our servlets, sets http headers on the response. And also returns a jpeg image (written to the OutputStream of response).

The current code does something on these lines:

 response.setHeader("Cache-Control", "no-store");
 response.setDateHeader("Expires", 0);
 response.setContentType("image/jpeg");
 ServletOutputStream responseOutputStream = response.getOutputStream();
 responseOutputStream.write(jprgImage);
 responseOutputStream.flush();
 responseOutputStream.close();

Can this be done using the jbr-provider ?

I tried to set the header params using HttpResponse. but that doesnt appear to work.

 HttpResponse resp = new HttpResponse(200);
 resp.addHeader(new HttpHeader("Expires", "0"));
 message.getBody().add(HttpResponse.RESPONSE_KEY, resp);
 return message;

Any help appreciated.

Thanks

:)

Try this:

message.getProperties().setProperty("Content-Type", new ResponseHeader("Content-Type", "image/jpeg"));

Thanks Scott,

That fixed the Content-Type issue.

I am still unable to send back binary data from the esb. Is that possible with the jbr-provider?

Thanks

Have you tried setting the payload as a byte[]?

The payload is returned to JBoss Remoting 'as is' and it looks like the marshaller should write the contents of the byte[] directly to the output stream.
