MQSeries.net :: View topic - JavaScript or JMS interface to Websphere MQ HttpBridge

I am trying to 'get a clue' with regards to doing a PUT and a destructive GET to MQHttpBridge from a CGI script.

I have searched to the end of the Internet for a barebones snippet of code that shows me how to do what I need to do.

I currently have 3 things that basically work with some issues. I have a CGI/PERL script and 2 java classes.

The java classes are compliations of butchered versions of HTTPPOST.java and HTTPDELETE.java renamed as MQPingPut.java and MQPingGet.java.

In the CGI, I call the java classes using system('my java call').

I am hoping to replace that "system('my java call')" with javascript or ajax to make this easier to use.

What I have works, but it not robust in RE to error handling and thus has to much likelihood of a false positive.

My objecting is to have a process by which in one click on ouor Wiki, production support can prove that MQ is not the cause of the problem. When the link is followed, the CGI runs and puts a ping message on a queue and that message is routed around a certain MQ circuit until it winds up on the response queue (same queue manager as request queue).

Does anyone have any code they don't mind sharing that I can put in my CGI script for the HttpBridge interface?

My java currently has something like this, but I do not know how to get it where it is useful in javascript. The java below actually works. I just can't get a "success indicator" back to the CGI.

HttpURLConnection connection = (HttpURLConnection) url.openConnection();

connection.setRequestMethod("POST");

String thisCorrelID = "hello11";
String thisExpiry = "30000"; // ten seconds

connection.setRequestProperty("content-type", "text/plain");
connection.setRequestProperty("x-msg-priority", "LOW");
connection.setRequestProperty("x-msg-expiry", thisExpiry);
connection.setRequestProperty("x-msg-correlID", thisCorrelID);

connection.setDoOutput(true);

OutputStream outputStream = connection.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(
outputStream));

writer.write(message + CRLF + CRLF);
writer.flush();

connection.connect();
