Hello all ,
I am new to WMB and Java. I have a Java code for which I am using RAD. Can I import this Java code into WMB and with some required change can we use this code for executing through WMB.
Thanks |

The WMB Java Compute Node (JCN) runs any Java. This is its strength and its weakness; many people (especially new to WMB people) start out thinking WMB is an application server like WAS and write JCN code like it's an MDB.
Or take an existing MDB and fit it in with a few changes.
This always leads to problems. Don't do it. Write Java that conforms to the expectations and framework WMB exposes.

You don't need Java in 95% of cases. Look at all the WMB nodes and ask an expert (in WMB) how to use the standard WMB features.
Don't use Java unless there is no other choice. WMB is meant to be a non or low programming solution. It is not meant to be a place to host java code.
WMB existed for 10 years without hosting any user-definable Java code - are you really sure that your requirement can't be done in the standard way - I seriously doubt it.
Advice from an experienced WMB developer is essential for those new to WMB and who (in our modern world) have been given no training (how did we come to this terrible amateurish approach?). |

WMB is not the only option.
I need to do it in a standard way only however since I know WMB (somewhat) better and find it more easy than Java so I thought of this approach.
Thanks all for suggestions. |

RAD provides no functions for working with WMB.
WMB Toolkit provides functions for working with Java code.
The place you need to start is to make sure you understand what the Java code actually does. Once you know that, you can consider whether to run it in a JCN or rewrite it in other functions of MB (esql, mapping, etc.), or not run it in Broker at all.
If the code is primarily designed to support user interface actions, you should not run it in Broker. |

Maybe not quite that long. MQSI had Java custom nodes long before WMB introduced Java Compute nodes, and many developers were equally happy to abuse those at the time.

Well, it were considerably more messy to write them before v5 came along and gave us eclipse-y things to play with.
It's always nice to look back on things like that and be thankful for the opportunities to have made mistakes and twice as thankful that they are no longer in production. |
