Hi I am a newbie.
How can I fetch messages present in MQ from a java compute node. i.e., I need the java code to fetch messages from MQ . I need to refine these messages in java compute node and then send that as an email content.
Could you please help me with it.
Thanks in advance |

don't do it.
Broker is not a J2EE environment.
how are you getting into the JCN in the first place? What event / piece of magic happened to allow your flow to cal use the JCN in the first place?

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

The message flow will get each message using the MQINPUT node, it can manipulate the content (as needed) in a mapping node or compute node (preferable to JCN) and then send it as email using EMAIL output node.
Do nothing other than field manipulation in a compute node (and only then if a mapping node can't be used).

And if your design absolutely requires you to pickup a message from a different queue, think MQGET node!
And please, please don't  wire any nodes in a loop

| Issue that I face is I am able to view the messages from MQExplorer. But I am not able to get that to next level. I will give it a try with your suggestion now and reply soon. |

No you don't, no more than you needed to do an sftp from your JCN. You were advised in your earlier thread here to use the features of IIB and not just pretend IIB = WAS.

What "next level"? If you're staring at the Toolkit pallet wondering how to get messages into a flow, that's the first level not the next level!

IIB comes with many sample applications.
They have lots of documentation and description of what they do.
They have full source available with them - the entire flow including the wired up nodes and all of the source for all of the transformation nodes in that flow.
They can be easily imported into your toolkit.
They can even easier be imported and RAN in your local testing environment. One Click Happiness!

Thank you all. MQGet node solved my problem(Initially I was playing around with my MQ Input Node...and I don't know why I was not able to get it through...). Only issue that I face now is that I am just able to get the MQ message as an attachment to my mail and not in the subject. I will have to figure that out some how. Anyway I am able to get the MQ message in my email attachment now.
Thank you all |

I think you mean the body.

Fix your code. Seriously. The message contents go where you put them.

So what starts your flow running?
I do hope you're not reading one message after the other in the same flow instance with the MQGet node. My worthy associate explicitly warned you against doing that for good reason.

| Based on this thread, it sounds like your effort has the potential to be problematic. So much so, that I am concerned you won't realize what problems exist before it is deemed complete. Perhaps it would be best if you posted a description of the requirements so you could get appropriate help. |
