Hi to all,
After crossing by a sea of tears trying to develop a plugin node in Java (due to documentation bugs and other problems) I have the clue about the way to do it without taking into account some doubts about exception propagation in the message flow. This can be expressed as follow:
1) In the API definition of all the Exceptions (Java PlugIn exceptions) such as MbFatalException, MbRecoverableException, etc; the constructor is defined:
| Quote: |
| MbRecoverableException(String className, String methodName, String messageSource, String messageKey, String traceText, Object[] inserts) |
But no further explanation is made about the meaning of each one of this parameters.
What is the meaning and use of the parameters messageSource and
messageKey?
How could I obtain it?
What about the last parameter?
What is it used for?
2) In my plugin node I have some code appart the typycal one relevant with the MQ architecture (for example to open a file). When I control the Exceptions (not WQMSI exception) ,for example in this case the IOException, I throw a new MbRecoverableException passing the exception cause in the parameter traceText like this:
| Quote: |
catch(IOException ioe)
{
throw new MbRecoverableException("SendMail","evaluate","","","Exception Produced",null);
} |
but, nevertheless, when I check the ExceptionList generated I obtain a following message:
| Quote: |
(0x1000000)Insert = (
(0x3000000)Type = 5
(0x3000000)Text = '<com.ibm.broker.plugin.MbRecoverableException class:SendMail method:evaluate source: key:message: Unable to resolve message: Source: Key: >' |
But I can not understand the reason why the 'ExceptionList' (better said the Broker) is not able to resolve message.
Could anybody please help me?
Has anybody worked over this sorts of problems?
Does the exception generated by a plugin node work prooperly?
Thanks in advance,
Regards |

Hi,
you can find ( indirectly  ) some usefull information in WMQI Programming Guide, "Implementing a plug-in node or parser" / "Using event logging from a plug-in".
Generally, you have to package your exception messages into a standard Java resource bundle. WMQI will resolve the message using messageSource ( name of your resource bundle ), messageKey ( key in the resource bundle ) and inserts ( parameters for your exception message ), and then insert it as a single text insert into the appropriate broker exception ( I think BIP4367 ). |

Can you please tell me the code you have used to develop this?

Hi,
I am having the same problem. Please could you (Bolek, Danielaphex or anybody else who can help) post an example of the code used to create an instance of MbRecoverableException.
In particular, do you create a java.util.ResourceBundle? What do you put in the Object[]?
Many thanks,
John |

Hi,
I am also facing the same problem can anybody help me out ?
here is the code;
public void evaluate(MbMessageAssembly arg0, MbInputTerminal arg1)
throws MbException {
try
{
MbMessage msg = arg0.getMessage();
MbElement rootElement = msg.getRootElement();
byte[] msgdata = msg.getBuffer();
String data = new String(msgdata);
int pos = data.indexOf("1,");
data = data.substring(pos);
byte[] bitstream = data.getBytes();
FTPClientTest obj = new FTPClientTest();
obj.FTPMessage(
attHost,
attUserName,
attPassword,
attLocalPathFile,
attRemoteFileName,
attRemotePathFile,
attTransferType,
attFTPType,
bitstream);
}
catch(IOException ioex)
{
throw new MbRecoverableException("FTPSend","evaluate","","","IOException Produced",null);
}
catch(FTPException ftpex)
{
throw new MbRecoverableException("FTPSend","evaluate","","","FTPException Produced",null);
}
catch(Exception _ex)
{
throw new MbRecoverableException("FTPSend","evaluate","","","Exception Produced",null);
}

It'd help others if you could share your solution to this problem.
