Querying BPEL Process Instances

The Oracle BPEL Console provides a great tool for monitoring the status of in-flight and completed process.

However it is often a requirement to present this information to a business user within a business specific view. One way of achieving this is to use the Oracle BPEL Portlets.

This is fine where you want to give the user a specific list of process instances, for example a list of all currently running Purchase Order processes. But what about when you need to give them a list more filtered to their specific business requirements.
In addition once you’ve located a process instance, how do I provide the user with access to relevant data contained within the process? Again the BPEL Console provides a mechanism for drilling into the process and looking at the audit trail for the data. But often we want to provide this data in a summarised business view designed specifically for the needs of the business user.

The Oracle BPEL PM Server provides a series of API’s that enable you to meet these requirements.

In fact what is not often realised is that the BPEL Console itself makes use of these API’s, giving you the flexibility to completely re-write the console if that is what’s required!!!

In reality this is rarely if ever the case, typically the requirement is to provide business users with a simplified view tailored to their specific needs. A simple way of achieving this is through the use of these API’s;
