Security QOS Usage in BPM V7.5.1


To demonstrate Security QOS  I had taken customer validation scenario.In this scenario customer details are sent to java component and its validates customer details based on customer name and send status back to BPEL.

 Security QOS have two options.

Security identity qualifier
The security identity qualifier is a privilege specification that you can use to provide a logical name for the identity under which the implementation executes at run time.

Location: A security identity qualifier is set on an implementation.

Security permission qualifier

The security permission qualifier specifies a role, which is a semantic grouping of permissions that a given type of users must have to use an operation in an interface.
Location: You can apply the qualifier at three levels of a component or import:
  • For all of its interfaces
  • For an individual interface
  • For an individual operation of an interface

Configuration for  security permission Qualifier:-

Here “Caller” is role name

Configuration for  security identity Qualifier:-

Then Save the flow and test it to then you got  the exception.like below

Error Message:-

If you observe the above message it was clear that username admin  have no permission to access component implementation .So to overcome this we need to follow below steps

  • Log on to admin console
  • Go to Websphere Enterprise Application.
  • Click on SecurityPOCApp and select “security role to user and GroupMapping “ as shown below.

  • Add  “admin” user to  Caller role as shown below .Select  Caller check box and click on Mapusers tab.

Test flow it works fine now.
