BPM Authentication On Behalf Business User from ADF

This is the next post in the series of ADF/BPM integration, check previous post available here - Dynamic ADF Buttons Solution for Oracle BPM Outcomes. Here I'm going to describe how you could authenticate with BPM from ADF through a proxy user, on top you could apply only business user name, password will not be required.

There is API method available - authenticateOnBehalf(context, userName), you must have a valid connection context created and with authenticateOnBehalf method you could set to use any valid user name, instead of proxy user. Here is the example for Workflow Context:


Similar example for BPM Context, same authenticateOnBehalf method:


As a proxy user I'm using weblogic. You could set to use any different user and consider it as a proxy user.

Tasks assigned for redsam1, connected through proxy user weblogic, are retrieved and displayed in the table:


This is how you could avoid using password for each business user and simply create initial connection through a proxy user. Download sample application - adfbpm11gr4.zip.

It looks like server config issue, can't point to Task Query service client.
