We recently upgraded to Axis 1.2.1 (from 1.1) and are seeing error like the one
shown below. We'll get from 1 to 3 of them (axis:type=server, axis:type=deploy,
axis:type=query) for each of the MBeans that the AxisServlet tries to register
on startup. In our configuration we have two separate webapps (separate .wars )
that each deploys an AxisServlet, so what appears to be happening is that there
is a naming clash when Axis tries register the MBeans. We don't always see the
error, and when we do don't always see it for all three Mbeans, for which I
don't have an good explanations.
Does anyone understand this issue better? Is there a way of configuring Axis
that we can avoid this problem (and still deploy multiple Axis enabled webapps)?
Thanks,
