      org.osesb.msgrouting.test.deployabletestpackage1.EchoMessageWithRandomPipelineStageExceptionPipelineStage

public class EchoMessageWithRandomPipelineStageExceptionPipelineStage
extends PipelineStage

Test PipelineStage configured by message-pipeline-4-test-config.xml.

See Also:

EchoMessageWithRandomPipelineStageExceptionPipelineStage#runStage() generates a random number. If the number is even, runStage() parses the input message using a pooled SAX parser and sets the result message for it's MessagePipeline to the content of the input message. If the number is odd, runStage() throws a PipelineStageException with the 'exceptionClassification' property set to 'testException'.

Creates a new instance of EchoMessageWithRandomPipelineStageExceptionPipelineStage.

Parameters:

parentMessagePipeline - The MessagePipeline that constructed this PipelineStage.

pipelineStageConfiguration - A PipelineStageConfiguration for this PipelineStage.

Throws:

java.lang.Exception - if constructed with a null parentMessagePipeline or a null pipelineStageConfiguration.

Method Detail

runStage

public boolean runStage(EAIMessage eaiMessage)
                 throws PipelineStageException

Run PipelineStage logic.

The runStage() method expects an IXMLMessage with XML text as the payload.

runStage() gennerates a random number. If the number is even, runStage() parses the input message using a pooled SAX parser and sets the result message for it's MessagePipeline to the content of the input message. If the number is odd, runStage() throws a PipelineStageException with the 'exceptionClassification' property set to 'testException'.

Overrides:

runStage in class PipelineStage

Parameters:

eaiMessage - The EAI message, which is the output of the last PipeLineStage that invoked setOutputMessage(), or, if this is the first PiplelineStage, then this is the EAIMessage that the MessagePipeline was invoked with.

Returns:

true to continue pipeline processing or false to terminate pipeline processing.

Throws:

a - PipelineStageException if any errors occur.
