Re: Axis2 1.5 + EclipseLink + Tomcat 6 = Exceptions, but only
sometimes
This may be caused by a missing getter method for one of the
properties in the class(es) returned by your service. Can you check
this?
Can you also open a JIRA report, please?

Re: Axis2 1.5 + EclipseLink + Tomcat 6 = Exceptions, but only sometimes
Posted by Greg Logan <gr...@usask.ca>.
There was a missing getter, but adding it in had no effect on the
exception. Any other suggestions?
I've created the JIRA report at
https://issues.apache.org/jira/browse/AXIS2-4389
Thanks,
G
