I am a WMB administrator with no development knowledge. I am testing message flow monitoring with a flow that contains many different type of nodes. The very basic test is to make sure an event generated when a message arrived to a node. So all I need is as simple as passing a message straight through the node. In the flow I have compute node and Java compute node and many others. I have no problem with compute node because it has the CopyEntireMessage(). All I need is just to un-comment the ESQL. But I cannot find the equivalent in the JCN. I follow the wizard, select Creating message class and get to the skeleton code
| Code: |
// create new empty message
MbMessage outMessage = new MbMessage();
MbMessageAssembly outAssembly = new MbMessageAssembly(contact admin,
outMessage);
try {
// optionally copy message headers
copyMessageHeaders(inMessage, outMessage);
// ----------------------------------------------------------
// Add user code below
// End of user code
// ---------------------------------------------------------- |
What should I put after Add user code below to get the equivalent of
CopyEntireMessage() as in regular compute node.
I use a simple flow for testing
MQINPUT -->JCN--> MQOUTPUT
I only get the MQMD if I do not add any code or if I just add the line outMessage = inMessage; (get this line by looking through this forum)
I am not a developer and do not know Java. I need some one who can help me out with this.
The code has to work with blob message also |

You followed the wrong wizard. Try following the one about changing / modifying the message

Try reviewing the javadocs on constructors for MBMessage.

Thanks fjb_saper, that works. I don't even have to add any code.
Thanks mqjeff for pointing out the Javadoc. I will try to read that when I have some time for my learning purpose. BTW , the javadoc you refer to is it in the infocenter or it is somewhere in the install path ? |

sort of both. If you have the local help installed/started/ then it's there, otherwise - https://www.ibm.com/support/knowledgecenter/SSMKHH_9.0.0/com.ibm.etools.mft.doc/as07392_.htm and click on "Java user-defined extensions API"
finding and using Javadocs is vital to using Java in general. So you should get familiar with it very early in your learning.
