Hi...
I am working with WBIMB v6.1.
I want know whether there is a way to call a external script or say an .exe file from within a message flow. |

Yes.
By using Java mechanisms for launching external programs from within a Java Compute node.
Or by using MQ Triggering.
You really need to think about this about ten times before you actually do it, though.

I am doing this using javacompute node.
But is there no way one can do it using esql?
By using triggering, you mean that..put the message to a queue which triggers the script? |

It's a really bad idea to do this at all.

Did you look for one? Did you find one?
No. ESQL can't do this.

I'm not sure what else "MQ Triggering" could mean.
It's a really bad idea to do this from within Broker! Unless there's a really good reason.

hmm...
but it is very much required to call the script.
It is a part of my error handling flow, that is required to raise a remedy ticket, which is done by invoking a script. |

Is'nt it better to change you error handling flow.
I suggest in this error handling flow sending simple message to some queue.
Then you can write application which just reads messages from this queue and raise a remedy ticket.

But that other application that reads the error message could be a java code as well right... So why cant we have it in the message flow itself?
I just want to know why is it bad to call the script from the message flow itself. Is there any particular reason? |
