Hi,
I have to transform some COBOL data to Java using WBIMB 6.0. Can I direcly map the data and use Java nodes to import thecopybook and filter data for transformation or should I first convert it into XML?
Thank You |

You "can" do whatever you want, works for you and is efficient.
If it is best practices you seek....
you might want to get the cobol msg using a message set created from the copybook and map it to your output structure...
Have fun...

What do you mean by 'to Java'? What's the output format?
as fjp_saper said, WMB has excellent support for transforming COBOL data using the MRM parser. Can you explain why that does not meet your needs? |

| 'Java' as in J2EE applications......MDBs for DB queries |

I presume ''MDBs' are Message-Driven Beans. Most people do the DB queries direct from their message flow, rather than creating an MDB and sending it to a J2EE app.
I think your best solution is to parse the COBOL message using the MRM parser ( so you'll need to create a message set and import the copybooks to create message definitions ). That will give you a message tree containing the parsed data. Then you can use a JavaCompute node to construct your MDB and do the query.
Somebody else may be able to suggest a better solution. |

Kimbert; we are using a construct like Giridhar is suggesting. However the message is transformed into a SOAP message by the broker. The MDB reads the SOAP message, transforms it into java objects (JAXB/JAXP/Axis) and performs the DB operations.
Advantage: your DB operations are scalable independently from the flow.
You could have 1 flow satisfy the volume but need 5 MDB instances to keep up with the volume for the DB operations...
Enjoy

Which is all well and good if you already have a J2EE App Server in the environment, and have staff and time to build an entirely separate application to do a database insert.

How do we enable the broker & MDB link ?
One approach is we can connect the WAS JMS queue using broker jms nodes or WAS websphere link.
Is it any other way ?
TIA
