    In some cases, Petals can loose end-points and not be able to restore them.
    Here is a scenario:

    • Configure the EIP SE 2.5 with the attached properties files (it must be referenced as an URL in its jbi.xml file).
    • Install the EIP SE 2.5 nd the SOAP BC 4.0.4.
    • Install the attached SA.
    • Launch the Petals web console. Stop the SA and sutdown it.
    • Still in the console, stop the components and shutdown them.
    • Restart the components and the SA. Take a look at the list of end-points...


    The SA's end-points do not appear anymore.
    You can also try listing them with the Petals command line ("l" command).

Fixed in branch petals-entreprise-3.1.x

Unregistration of all endpoints has been moved from DeliveryChannelImpl.close() to Installer.doUninstall. So, if endpoints are remaining, they will be unregistered when uninstalling the component.

IMO, endpoints registered through a service unit MUST be only deregistered when undeploying the service unit.

Analysis:

  • Endpoint are deregistered when closing the delivery channel.
  • The delivery channel is closed when shut-downing the component.

Using the petals-samples-client at each step to check the registered endpoint, we can see that the endpoint is deregister when shutdowning the SE EIP.

Moreover, undeploying the SA just after to have restart the component, we get the following error:
