Hi,
A java service lets you write and execute java code on the Integration Server.
The Service Development help at Building Java Services is a good starting point to understand more. Please feel free to reach out if you get into any issues.

Why do you want to avoid using wMPublic package services?

A rule of thumb for IS development that you’ll want to consider: avoid creating Java services unless the desired function cannot be achieved using FLOW.

@reamon,
I believe the intention is perhaps to explore the Integration Server and get familiar. Completely agree with your point about using FLOW.

P.S: Thoroughly enjoyed the topic - Integration Server and Java started by someone , a very good read indeed.
