Can anyone please help me on putting the message directly on the output queue from java compute node? I am talking about the string message. After logic in JCN, i am storing the result in string variable. I want to put this string value in string variable directly to the output queue or defined queue name.
I would appreciate if any sample code help here |

Do not do this. Broker mediates all connectivity between itself and the queue manager. At best you'll break the transactional integrity of the flow, at worst you'll bring the broker down.
Use the MQOutput node to write this value to a queue. Likewise only use the MQInput or MQGet nodes to read from a queue.

Something like this:
1. Convert the string to a byte array, specifying the encoding:
| Code: |
| byte[] myByteArrray = myStringValue.getBytes(theEncodingExpectedByTheReceiver); |
2. Create a message body in the BLOB domain, create the only allowable child element 'BLOB' and assign the byte array to it:
| Code: |
| root.createElementAsLastChild(MbBLOB.PARSER_NAME).createElementAsLastChild(MbElement.TYPE_NAME, 'BLOB', myByteArray); |
3. Propagate that message tree to an MQOutput node, where it will be written to the queue. Don't try to implement that part in Java. |
