Suppose there are 10 workitems on the worklist. How do we know which workitems input or output container we are accessing. Is there a way to identify a particular workitem with some kind of id using Java API.
Thanks in Advance

You should do some real simple programming to know this otherwise whatever we tell you you will not be able to get. I'll still try but then again...
A work list contains work items.
Each work item has an INPUT container and an OUTPUT container. Now what is your problem.
Some of the samples at

Hey Dragon,
There's a persistentOID associated with every workitem and this is unique. You can access this OID via the API call getPersistentOID().
Since u use java i am assuming that u use value objects (java beans) to map the workitem attributes and the input container, so map the OID also in u r java bean.
When a user cherry picks a workitem u 've to pass the correct OID to API setPersistentOID() so that the same workitem is reconstructed. Now u can call methods on that workitem to access the input/output containers.
One caution u 've to take is the OID might contain wild card charectors (e.g +) so if u use web interface and if u pass the OID as querystring to server u will 've to encode it.
Best of luck

Yes, one way is to use the name of the program assigned to the activity.

No, you cant use this, as there will be multiple Workitems for the same program derived from different Process Instances.
Manoj's solution is the way to go.

Ratan,
It depends on how you read the initial post;
A single question that I believe was DF's intention:
- Supposing there are 10 different workitems on the worklist, is there a way to identify what are the input and output containers for particular workitem with some kind of id ?
Two distinct questions:
- Supposing there are 10 different workitems on the worklist, how do we know which workitems input or output container we are accessing ?
- Supposing there are 10 different workitems on the worklist, is there a way to identify a particular workitem with some kind of id using Java API ?
I replied as to the single question and I think the answer is right.

We are getting the object does not exist error and found it is because of '+' in oid.

Manoj, We are facing the same problem. What do u mean by encoding the OId? How we can do it? Can u give me an example please.
Anybody who has handled it, I would appreciate their comments.
Thanks,

Mahesh,
I believe Manoj was talking about using the static methods of java.net.URLEncoder and java.net.URLDecoder to encode/decode the object IDs when these IDs are used as URL parameters.
