Does user trace not work?
MbService has log methods.

Hi Jeff,
All I see is:
| Quote: |
2007-05-04 14:49:50.320873 4212 UserTrace BIP3904I: Invoking the evaluate() method of node (class='ComIbmJavaComputeNode', name='mfJavaTest01#FCMComposite_1_3').
About to pass a message to the evaluate() method of the specified node.
No user action required.

I would like to see what went on in there ... as you can see I am a Java novice! |

Okay, user trace doesn't work... That was at debug level?
The Java code will have to be changed, then.
Unfortunately, there's currently no way to detect if user trace is enabled from within your code.

Hi TonyD,
by using the following command u can debug ur javacode using flow debugger
| Code: |
mqsichangeproperties <broker-name> -e <execution-group-name> -o ComIbmJVMManager -n jvmDebugPort -v <port-number>
|
In debugger u have enable the javadebugger and give the port no which u gave the port in the above command.
For more info go thru the Toolkit--->Help
Cheers,
Vijji. |

one option would be to use log4j logging. If you are using the logging using the logging api provided by MB then that could result in a flood of trace messages on the syslog unless logic is written in to switch the tracing on/off or change logging levels dynamically.
Both would however involve change in existing code. |
