I can't get MbElement.toBitstream() to work properly.
The following code snippet (Java Compute Node) returns en empty array:
| Code: |
public class JavaGdsVcomCsCall extends MbJavaComputeNode {
private MbElementUtil util = new MbElementUtil();
public void evaluate(MbMessageAssembly contact admin) throws MbException {
try {
// Get rootElement
MbElement rootElement = contact admin.getMessage().getRootElement();
// Get the data as a bitstream
String requestMessageSet = "EGCJ700002001";
String requestMessageType = "msg_R9I34101";
String requestMessageFormat = "CWF";
byte [] msgAsBytes = rootElement.getLastChild().toBitstream(requestMessageType,requestMessageSet,requestMessageFormat,0,0,0);
|
I have verified that the message sent into the Java Compute Node is of the Set and Type as specified above.
WMB version is 6.0.0.1.
Any clue on what I'm doing wrong?
Regards,
Magnus. |

Thanks for your advice but I have actually named the Physical Format "CWF".
Are there any working examples on calling toBitstream() available?
Starting from something that actually works is maybe the easiest way forward...

Magnus. |

| Have you tried searching for 'toBitstream()' on this forum? |

Absolutelty, I read all 14 topics carefully 
However, I got an suggestion to temporary replace the Java compute node by a MQ Output node to see what happens. The ideas was that if the message is successfully written to the MQ queue then the call to toBitstream() "should" work.
As you probably can imagine the message written to the queue also contained 0 bytes of data.
After finding the problem using the temporary MQ Output node I switched back to the Java Compute node...
...and the call to toBitstream() now works (of course)
So it was all a matter of finding a proper method for isolating the problem.
Thanks anyhow for your suggestions!
Regards,
Magnus. |
