| I am helping IBM to establish message broker in a Java only shop. The company were sold on the benefit of WMB and have V7 installed. However the company has only Java developers and strongly against the use of WMB. I have read reports on JCN and ESQL transform and the performance difference is getting really close. So they can code in Java. However they always want to call external Java classes when ever the broker allows instead of coding Java code inside JCN. For example I explain to them that they can use mapping node and JCN to do transformation. However they want to code transformation using Java outside of the broker and have the broker call the Java function. I am not a Java person, I think that they are not taking advantages of features provided by the broker and this may be quite inefficient. But I may be wrong. I need some helps on how I can convince them to use WMB. |

Sort of. Less risk of being eaten by sharks, though. |

Thanks for the advice. I read a similar recent post regarding ESQL and Java. I think my situation is quite similar. Development manager and developers are not paying for the Software , so they don't care how much WMB is. They have a dead line to meet and no training budget. Calling Java everywhere from the broker will meet their requirement of making senior management happy by using what they paid for and getting things done fast with no additional training cost.
There are some good points from the other entry. Such as on demand Parsing and bridging CWF programs ,such as COBOL, is probably Java is not able to do or do efficiently. Please correct me if Java can also do the same. |

You can almost do anything in Java. Will it be done in the most efficient manner, will it leverage the capabilities of WMB 7 and give the company a decent ROI?
Will they get support for the code parts that do not leverage the broker's capabilities? Those are the questions they need to ask themselves...
Have fun

It may well do until....
the Java fanbois try to code as it they are woring in a J2EE Environment.
If they also go mad with class abstraction they may end up chasing their tails.
Tell them to
Keep it simple
Then you might get somewhere.
I once challenged a Java developer to a race. We had to develop a flow that received a WebService call and send some data to SAP. I did the job (ok fairly crudely) without writing a line of ESQL (thanks to the mapping node). The white flag was soon raised by the competition. That made him a convert to the abilities of broker to 'just do stuff'.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |
