You are embedding Runtime Engine in an application using the Java SDK. When you run the transformation that was saved in Scenario 1 on the command line, the console displays error 25531. In this case, the Java application must print the return code and error message to its console (this is not done automatically, but must be configured using the SDK).

As you can see from the three scenarios, the error return codes originate from the Runtime Engine and are displayed in various formats, depending upon the user interface. Errors generated from the editors are written to a log file, while errors that occur on the command line are printed to the console. The error in Scenario 1 was a design time error, while the errors in Scenario 2 and 3 were errors that were generated at run-time.
