[jira] Commented: (AXIS2-1964) Null Pointer Exception in Service
STUB class at _operationClient.execute(true); line for AXIS2 1.1.1
[ https://issues.apache.org/jira/browse/AXIS2-1964?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12474072 ]
Eric Deshayes commented on AXIS2-1964:
--------------------------------------
if that can help, the problem seems to be the fact that the response type inherits from another type.
I have had the same issue, and, with my wsdl, the elements of the inherited type are set with an empty namespace.
To check that empty namespace value, set a breakpoint when the sendUsingOutputStream method is called from the invokeMessage method of the CommonsHTTPTransportSender class (line 208 of axis2-1.1.1 release).
a work around (the one i use) is not to use any inheritance for the return type...
I will try to investigate that issue this week.
Regards,
Eric
