Hi,
I want to run user defined java classes when broker starts up to initialize the environment for all message flows deployed in the broker , can anyone tell me how to do that?
Thanks! |

Can't be done.
The best you can get is a constructor on a JCN or a custom-plugin.

Can I use java classloader, or static initializer in a referenced java class from JCN (Java Compute Node) ?
Thanks! |

What do you think you want to do, by using one of these mechanisms?
I'm sure there's a better way.

I have a broker with many message flows deployed in it, I want to load information from database at broker startup, and cache it in memory, so all message flows in the broker can share and access the information without visiting the database every time
What better way do you think?
Thanks! |

Use IA91.
Also, remember that each ExecutionGroup is it's own JVM. So there's no way - without using IA91! - to share data between ALL message flows.
