Subject A suspectable bug of 1.3.3 - AxisFault: Two services cannot have same name
Date Mon, 10 Aug 2009 10:19:33 GMT
Hello,  

  With ODE 1.3.3, it seems that multiple consecutive invocations to a same component service
will incur the following exception:

ERROR - GeronimoLog.error(108) | Error sending message to Axis2 for ODE mex {PartnerRoleMex#hqejbhcnphr4i3dscxlf10
[PID {http://scqr.bupt.edu.cn/solution}process_SyntheticBookService_sol2-12] calling null.operation1(...)}
org.apache.axis2.AxisFault: Two services cannot have same name.  A service with the axis_service_for_{http://example.org/writerInfo}writerInfoService#writerInfoPort_hqejbhcnphr4i3dscxlf0r
name already exists in the system.

But the same actions doesn't incur any exception in with 1.3.2 or 2.0. So I think this maybe
is a bug, isn't it? 

And I noted that a similar problem has been discussed in 2007( https://issues.apache.org/jira/browse/AXIS2-1182?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12476874
). 

The attached is almost all the needed to replay the exception - the process, 2 component services(running
in Axis2), and the SOAP request message of the process.  There is another coponent service
which is omitted for space reason. But in most cases, the previous exception will occur before
it is invoked.
