handle

public void handle(ExecutionImpl execution,
                   java.lang.Exception exception,
                   ProcessElementImpl processElementImpl)

Handles the exception. This method will execute compensating code in the same TX or in another TX (depending on the value of isTransactional field). The compensating code is not in this method, but in executeHandler(ExecutionImpl, Exception, ProcessElementImpl) method.

Parameters:

execution - the execution which produced the exception

exception - the exception to handle

processElementImpl - the process element the exception handler was triggered from.

executeHandler

protected void executeHandler(ExecutionImpl execution,
                              java.lang.Exception exception,
                              ProcessElementImpl processElementImpl)

Compensating code for the exception. This method is called from handle(ExecutionImpl, Exception, ProcessElementImpl) or from ExceptionHandlerSynchronization and should not be called directly. Extensions should overwrite this method.

Parameters:

execution - the execution which produced the exception

exception - the exception to handle

processElementImpl - the process element the exception handler was triggered from.

rethrow

public static void rethrow(java.lang.Exception exception,
                           java.lang.String prefixMessage)
