public methods
---------------------------------------------------------------------------------------------
Key: AXIS2-465
URL: http://issues.apache.org/jira/browse/AXIS2-465
Project: Apache Axis 2.0 (Axis2)
Type: Bug
Reporter: Noah Levitt
Priority: Minor
I created a service class with one method and I forgot to scope it public, and
I got this response when attempting to view the wsdl, which didn't really help
me identify the problem:
