Why do we sometimes need an integration tooling like OpenESB when using drools ?

When working with drools project, the drools that need to be implemented apply on a data model. Most of the times, a lot of data need to be retrieved from different applications or third parties. To avoid writing to much java code, we try to use tools where we can fetch all those data not by writing code (like java) but by writing configuration integration code. It is here where OpenESB comes in.

Here is the documentation to start with OenESB. The OpenESB site is here. There are very good tutorials on the Pymma web site
