JR61320: CONVERTING AN INTEGRATION SERVICE THAT HAS A JAVA INTEGRATION FAILS IF THE JAVA CLASS HAS OVERLOADED METHODS

workflow.20001.delta.repository

APAR status

• Closed as program error.

Error description

• In the web IBM Process Designer, when you convert a heritage
  integration service that contains a Java integration step the
  conversion completes but shows the following message:
  
  "The following converted service flows have unsupported
  artifacts that are converted into placeholder service tasks.
  Test and edit the service flows in the web Process Designer to
  ensure they work correctly."
  
  When you open the converted service flow, you notice the Java
  integration step is annotated with the following text: "An error
  occurred while trying to convert the 'Call SOAP w/Auth' Java
  Integration component. See SystemOut.log for details."
  
  In the SystemOut.log file, you see that a
  java.lang.IndexOutOfBoundsException error is logged. You might
  also notice one or all of the issues after the conversion:
  - There are two or more newly created external services that are
  named similar (such as with a number appended to the name) and
  each of the external services wrap the same Java class.
  - At the service activity that has the converted Java
  integration, the operation binding is lost.
  - At the service activity that has the converted Java
  integration, the parameter mapping is lost.
  
  For reference, this is the stack trace of the
  java.lang.IndexOutOfBoundsException:

Local fix

• Before you convert the services, ensure that you have a backup
  (snapshot) that you can view in the desktop Process Designer.
  
  After the services are converted, go through each of the
  services and each of the activities that has an error
  annotation, choose the intended method, re-enter the data
  mapping from the values in the backup in the desktop Process
  Designer, change the color of the activity to gray, and remove
  the error annotation from the diagram.
  

Problem summary

•   During a service conversion, the Java integration step is
    replaced by a new external service with Java binding and a
    service task bound to the external service. The operation and
    parameter mappings of the service task are based on the newly
    created external service. The assignment might fail if the
    Java class has two methods with the same name but only the
    method parameters are different.

Problem conclusion

• A fix that corrects the algorithm used during service conversion
   will be available in a future release of Business Automation
  Workflow.
