IRIS BPL iteration

Example of a Business Process with an arbitrary number of call requests.

What does this example showcase?

Requests passing through an IRIS production may cause a Business Process to execute a certain call action repeatedly, with the number of repetitions unknown. This example shows how to deal with that.

The production in this example reads a file with an arbitrary number of questions, each with a varying number of possible answers. The questions are forwarded to a workflow operation, where the IRIS user SuperUser picks one of the choices as an answer. Each answer is written to a file, as is the summary of all the answers.

How do I get this example to run?

1. Clone this repository and import the ObjectScript classes into an IRIS instance.
2. Configure the File Path settings of both the FileService and FileOperation components to point to existing directories on your machine.
3. Start BPLIteration.Production.
4. Copy the QuestionsSamples.txt file into the File Path directory of FileService
5. Look at the visual trace.
6. Log in as SuperUser, open the workflow dashboard and process the workflow tasks.
7. Refresh the visual trace to see the effect.
8. Have a look at BPLIteration.MultipleQuestionsBLP and BPLIteration.SingleQuestionBPL to see how the variable number of call requests is handled.

Additional remarks

Upon compilation, the Setup class does a few preparatory things:

• it makes the current namespace interoperability-enabled;
• it promotes the standard IRIS user SuperUser to a workflow user;
• it creates a workflow role Guru and assigns it to SuperUser;
• it activates Analytics for the current namespace and sets password authentication for the current namespace, so SuperUser can access the workflow dashboard.
