Hi All,

I am working on Http service in message broker which will receives a request from the browser.
Based on the request type , It need to retrieve the document from the file system and send the response as pdf to the caller(Need to be displayed as pdf in browser).

For this Req I have created a flow with HTTPinputNode-->compute Node-->HttpReply Node.

please give some suggestions on the below.

Is it possible to implement the above using message broker?

If yes what are all the HTTP Reply headers that i need to set?

What is the format of the http Payload?

I tried with the below code but it did't work

SET OutputRoot.HTTPReplyHeader."Content-Type"='application/pdf';
SET OutputRoot.BLOB.BLOB=CAST(SomeString as BLOB);

Thanks in Advance..

How do you think you will read from the File system in a Compute node?

I see two main issues that you face.
1) Getting the HTTPReply message formatted correctly
2) Getting the PDF properly cast to a BLOB

The first can be acheived by importing the relevant sample flow into your Toolkit, deploying it after inserting TraceNodes at the relevant parts of the flow and examining the usertrace output.

The second is a pretty common issue. There are many posts in this forum where casting something to a BLOB is discussed. Take a look at them and see what you learn.

Try these and then by all means come back to us with more questions.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.
