I am sorry. The above is true only for MBService's log information. This may not be true for system.out.println

In general, do not use System.out.println from Java nodes in Broker.
Use MbService or log4j instead.

I copiing the previous discussion for you:
The MB Logging API sure does contain methods logInformation() and logWarning() which could make people think otherwise. As Jeff said, the only logical use of it is to throw up errors from within java code to the MB log.
Generally, you're better off using MbService methods to do logging.
I checked the "java.io.tmpdir" and couldn't find anything there
If you really, somehow, need statement-by-statement logging, then you can use log4j without much trouble.

i also saw the below:
When you start your broker from windows services, check the option "Allow services to interact with Desktop" and you will be able to see the System.out.println calls printed on your DataFlowEngine console.

Hi,
I am unable to find the option anywhere when starting the broker from the services window.
Please explain a bit.
Thanks.

Actually, the option is available for Local System id.
If you are running the service under a different id you can't use the option, which is the case with me.
So, how/where do we find the output of a println() statement in a JCN if I am running the broker service under a different id ?
Thanks.

In general, you SHOULD NOT USE println from a JCN.
