First I would like to know what i should enter in the fields,
[b]Path and file Name:
Command Line Parameters:[/b]
If i want to run a JAVA program................
How can i find the name of this workitem which is running this program....
If i do a workitem.name,it will return all the existing workitem names,isn't it ?????
I want to get only this name which is responsible for running this program. |

Note that this is not really a good way to run things, since you will be constantly creating processes and JVMs. This is a fat client implementation and is fine for experimenting or for a utilitity program, but you really should use a thin (Web) client implementation for client use.

No it gets you the name of the current workitem
I.E.
WorkItem [] wi = es.queryWorkItems(, , ,)
Any item name is wi[i].name();

I havent got it,sorry.....
If i have one processInstance.......even if 10 workitems are created they will call 10 instances of the common JAVA program.
All the 10 started JAVA programs on doing "es.queryWorkItems( , , ,)" will return the array of all 10 workItems.......
I dont want this.....i want each program to know which was the workItem which called it......so i mean it will return its unique workItem.
I hope i'm making sense....... |

I am assuming that you mean that you have one activity assigned to 10 different people. The flaw in your logic is that although only one of those workitems will ever run, there are indeed 10 workitems with the exact same Activity name and the exact same Process Instance Name.
I am not certain exactly what your question is.

Ya, you have got my problem......but i think i have figured out a solution for myself.....How is this.....
My data container has a code field which is unique in each work item,so i can pass this as a command line parameter......
This program is actually for waiting on a queue....so i will get this same code value from the Queue message and compare will all the workitems to identify which my workitem is 
is it possible to pass workItem name or some unique detail like that in the parameter field ???? This will help me pick the workItem easily |

Sound like you are doing a brain surgery on something this is pretty simple. If you can let us know what you are trying to achieve, may be we can figure out an easy solution.

ok i'll explain...............
I've started a process instance with the help of a JAVA standalone application which is continuously waiting on a queue.....The data from the queue is made the input container....I can have same identical details coming for different workItems.
Once the instance is started,the first work item is running another JAVA program (Automatically) which should wait on another queue to get some new information related to the message from the first queue
i.e both the messages have to be compared to be sisters......
Now the problem was that,if i have same data in multiple workItems.....I would pick the message from 2nd queue,and do the compare to the first successfully compared workItem,and finish it,even though it was not the one which started this JAVA program....
I hope u got it......this is why i had to introduce a unique id for each workItem to identify workItems uniquely.....
Plz forget it if i'm not making any sense  |

How?
Using XML interface or using Java API's
Either way, you should be able to create (or get) the process instance name. That itself is your unique identifier.

Infact it doesn't. Maybe you are missing some more pieces of it. I don't understand the whole concept of waiting on queues. |

MQSI is communicating to WorkFlow.....so i am getting data messages(message1, message2) on 2 queues (queue1, queue2) from MQSI.
Both the data messages must have arrived to continue the workflow at a point say "A"......
there is no unique field in the message2 in queue2 to identify it as the sister concern of the first message1 in queue1 that has arrived first,since they come from totally unrelated places.....
so if i start the workflow with message1 from queue1,i wait now at point "A" for message2 from queue2,now even if i have the processInstance Name,it dosent help me in identification of the correct sister message2.......
I could only figure out that i have to introduce a id in both messages....... |

Looks like that's the only way.
If the messages are external and not controlled by workflow, then you have to find a way for yourself |
