oracle.apps.fnd.applcp.request.exec
Class ExecutableWrapper

java.lang.Object
  oracle.apps.fnd.applcp.request.exec.ExecWrapperBase
      oracle.apps.fnd.applcp.request.exec.ExecutableWrapper

All Implemented Interfaces:

oracle.as.scheduler.Cancellable, oracle.as.scheduler.Executable

public class ExecutableWrapper
extends ExecWrapperBase
implements oracle.as.scheduler.Executable, oracle.as.scheduler.Cancellable

This class is used to wrap the program executable to perform certain important tasks before control is handed off to the program executable and after control is returned from it.

This class replaces the program executable class as the ESS executable in the pre-processing phase. When ESS enters the execution stage, it run this class. At this point, this class performs two actions:

• Setup the RequestInfoMap for support classes
• Run the program executable

This class also implements the Cancellable interface. When cancel() is called on this class, it in turn inspects to see if the underlying program executable implements Cancellable and if yes, invokes it. Else no action is performed.

At the end of the execution, all open resources are closed and control is is returned back to ESS. If an unexpected error occurs during program execution, this error is caught, logged (to the request log file) and re-thrown appropriately.
