Bug and improvement in OpenESB



If you find a bug or want to suggest an improvement or a new feature in OpenESB, please report them in the OpenESB JIRA

Please notice:OpenESB is an integration product which by definition, works with many other products, applications and platforms. Your background showed us that in a large majority of the bug in OpenESB are due to the interaction with the third parties and does not come from OpenESB itself. So, when a bug occurs, we strongly advise the OpenESB user to simplify the context and create a very simple project we can use and try to run in our labs to reproduce the bug. Otherwise, we could not help you.
