Hi,
I have defined an activity which is assigned to a user "USER".
The activity is to start automatically and end automatically too.The USER has been given admin privilages.
When the data container comes to this activity it fails to start automatically.It is in ready state....On some searching i came to know that the user needs to be logged in to make the program start automatically....
So what i'm doing now is that,I first logon the USER using Java api's, and then submit the inContainer to it.....but this is not working too.....If i do a login from the WF client for the first time and then use these api's, it starts working....but i cannot expect someone to do this in a realtime scenario after every server crash,.....
Can someone suggest where i could be going wrong......
Is it possible to avoid this USER assigning to the workItem.....
Also,when the system shuts down or something this activity will get completed successfully. How do i prevent this, and make it start again. |

It is recommended to use UPES for all automatic activities. This will get you around having to have the user logged in.

ok, all i know about UPES is that it stands for user-defined program execution servers....
Can u tell me where i can learn about implementing this,or if u could take the time, can u tell me how to implement running a java program in an activity which should start and end automatically.
Anything would be helpful.thx. |

A crude explanation : You have to define your task as a UPES task and associate the UPES with a queue. When the activity executes in Workflow, an ActivityImpl message will be put into this queue. You could run your java application to get this message and retrieve the input container values from it. After processing the message, populate the output container values inside an ActivityImplResponse message and put it into the queue EXEXMLINPUTQ. The activity will resume with its output container values sourced from the message you sent.
You could use the UPES Framework classes in your java application. These come as part of Workflow installation or as a supportpac.
Refer to Chapter 33 of the Programming Guide to know how to implement an UPES, XML interace and error handling. |

I tried the UPES functionality but have realised that i cannot have mutiple cmd's running for each message( for each Java program that i will have to run) and also since the programs have a dynamic timeout i cannot use the initiation queue cmd for each program.
Can some one tell me what i could be doing wrong in the present scenario...
I have three activities and a user for each.....2 activities have manual start and the third is automatic.....
I am logging in all the three users and get a successful logon2....
Both the manual activities are running properly but this automatic activity fails to start automaticaly...the workItem comes there and is in Ready state......
There is nothing wrong with the code since, if for the first time i keep the user logged on( of the automatic activity ) the workItem starts automatically......
Is this a dependancy..??
Is there something i havent set ???
I have set the program must run unattended and the start automatic features |

So When do you see the problem?
Do you have any exit conditions set?

to produce a real life scenario,i stop and start the services to make sure no users are logged in......
After this i run the workflow using the Java Api's....
The activity supposed to start automatically receives the workItem in ready state but does not start the Java application set in the program implementation for this activity.....
Note : the Java application runs if i go to the workflow client and log in the user for the first time....
My logon statement is :
service.logon2( userid, password, SessionMode.PRESENT, AbsenceIndicator.LEAVE)
Are any of the settings a problem ????? |

What is the exact logon command you are using in the Java program?

If you donot have a PEA running for the user assigned to an automatic activity ( when not using UPES), there is no way for the activity to run. So I believe what you see is how Workflow works.
To get around this, keep the PEA for that user always running, or BETTER YET USE A UPES.

Using this command you can log on any user multiple times. But that user will not be running automatic activities.
