I have a MQinput, a Java compute node, and a MQoutput node.
i put some XML message in the queue of MQinput node and because of that flow gets triggred.
i want the flow to be executed after java compute node only if the message satisfes some condition, otherwise not.
How can i do this. |

Message is propagated by:
out.propagate(assembly);
So condition that statement in your java. |

i have to do this in java compute node.
i can't use ESQL code. and in filter node we use ESQL. so i cant use Filter node. |

hey
U can use Java Compute Node as a filter Node...
In JCN there are two terminals.. Out and alt....
just propagate thru 'out' when condition is met ,otherwise thru 'alt' ...
hope this is what u want.........
cheers

Spidy,
What pravin meant from his question is
if the condition met he want to extract and propagate the message in JCN else he does not want to do nothing. Am i right pravin.
In ESQL there is option
Propagate NOWHERE.

Hi prakusi,

In that case, do an out.propagate(assembly)(to whichever terminal) and don't connect that terminal in the flow

or simply do not do out.propagate(assembly).

I thought of that after I posted the reply  Didn't want to take the pain of editing, plus wouldn't it be better that, if tomorrow prakusi decides to take the "false" of the filter, he wouldn't have to change code..  Do u think performance difference will be noticable ?
Regards. |

Performance difference? Between calling an undefined subroutine, and not calling an undefined subroutine?
I suppose someone *could* measure a difference. I don't know why they'd bother.
