WMQhttp

Standalone Websphere MQ http-bridge with zero configuration.

Why

The official implementation of the IBM requires an application server and JMS settings for the application. Here everything is simpler, it's enough just to start the service and send a request with a header containing information about the queue, the service itself will try to connect and cache this connection with the queue. It is also possible to read messages by cursor without deleting messages.

Examples

You need to write a wmq-params header with the parameters of the queue manager and the queue.

• Receive a message or wait while it appears:

curl -X GET -H 'wmq-params: {"type":"rm","host":"127.0.0.1","port":1414,"channel":"CH1","queue":"q1","manager":"QM1","message":{"wait":true}}' http://localhost:3000/wmq

• Upload message:

curl -X POST -d 'message test' -H 'wmq-params: {"type":"wr","host":"127.0.0.1","port":1414,"channel":"CH1","queue":"q1","manager":"QM1","message":{"wait":true}}' http://localhost:3000/wmq

• Read messages by cursor, without removal. You will need to set a unique id for your reading session, in the "cursor":

curl -X GET -H 'wmq-params: {"type":"rd","host":"127.0.0.1","port":1414,"channel":"CH1","queue":"q1","manager":"QM1", "message":{"wait":true, "cursor":"a6aa55bb"}}' http://localhost:3000/wmq

Build

The application uses IBM proprietary libraries for work, I can not upload them here. So you need to put them in the folder libs/ibm. List of necessary jars:

• com.ibm.mq.commonservices.jar
• com.ibm.mq.headers.jar
• com.ibm.mq.jar
• com.ibm.mq.jmqi.jar
• connector.jar

Then just run the "gradle build" and execute jar with port number:
java -jar wmqhttp.jar 8080
