Hi! I was wondering if someone could help me figure this out:
We are trying to migrate some minor user-defined nodes we have written from version 5 to 6.1. In order not to drag anything problematic with us from the old workspace, we did a clean rewrite using the instructions in the help files.
We can get them to appear OK in the toolkit by installing the resulting jar file in it, but we are having problems installing the jar in the broker.
We did create a separate directory for the jar file, did add it to the lil path with "mqsichangebroker -l", but when we start the broker again, we get null pointer exceptions in it:

The exceptions seem to indicate navive code being involved, but out jar only contains java classes, so we are a bit confused... |

I have similar type of problem but not exactly the same.
What i did was i copied all the code from the user defined node(from .java file) and pasted into the JavaComputeNode.
It worked good.Without any extra efforts.
