Are you sure your labelname field is holding a valid label name?

It's probably worth removing it from shared-classes and restarting.
It might not be loading them from the BAR in EGShared because it already finds them in shared-classes.
It seems EgSharedClassL ... |

There may be classes that are required for the framework that aren't in the jar file for the framework.
I posted a link to the InfoCenter documentation that shows you the different classloaders, in ... |

The stuff you've put in the BAR file may depend on things that aren't in any of the JARs.
I saw three classLoaders in debug view, DummyClassLoader, EgSharedClassLoader, and SharedClassLoader

If you're still getting this error, then you don't have everything you need in the BAR file.
You put everything in one classloader by putting it all in the BAR.
I did put it into Bar file, I can ... |

No, I'm not suggesting it one way or another.
I'm suggesting that you keep track of which classloader is going to be asked to load which classes - and make sure that the necessary classes are visib ... |

So is the JCN creating the instance of the concrete class, or the framework?
The JCN is going to be under a different classloader. It will be able to see anything that's in shared-classes. But sh ... |

It's either a classloader problem or a simple problem of not having the right class on the classpath.
*where* on the "workpath" did you put the jar file?
Did you restart broker after d ... |

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 databas ... |

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) ?

Oddly enough, the documentation tells you where to find the samples.
Actually, the link to the sample in the documentation is broken, I tried it |

Looks like you may need some training, or at least a 6.0 refresher course... 
Read up in the documentation and look at the samples...
Enjoy
Thanks! Where to find the sample? |
