My Aim:
=======
My Process Component is using an Import Component configured for MQJMS. All is working well when I select one of the out the box data binding configurations.
But I need to send a custom format of XML to MQ so I have attempted to create my own data binding class to do the conversion from SDO to MQ Message.
I have created my own data binder in a library project which is correctly set up as a dependency as I can browser and select my class in the property fields in the
Import properties component. I have attempted to follow the help guide and have some issues ( or mis understandings ) - as over riding the binding does not seem to work.
I believe my problems may be due two either:
1) Help Guide Example of custom MQ data bindings section: I cant find class WMQBodyDataBinding as listed in the example of overriding the body? So in my class I "extends MQDataBindingImplJava" and overide this public void write(MQMD md, List headers, MQDataOutputStream output).
2) I have changed all the place that reference data bindings to reference my binding class both in the binding tab and the methods task, is there any more places I need to change?
thanks in advance,
JOhn |

Yep , solved my issue ( and forgot to update this-apologies).
Basically it was a sort of classpath issue.
I was trying to override:
public void write(MQMD md, List headers, MQDataOutputStream output).
but when I was doing the import ( i.e. ctrl-space + select in the dropdown in java editor )I imported the MQMD class say for illustration com.ibm.mq.MQMD, but the class used in the method signature was com.ibm.processserver.MQMD, so I was overloading the method as opposed to overwriting- hence picking up the OOTB data binding classes. DOH
The actual package names I cant remember - but hopefully clear..
cheers,
John |
