Axis servlet throws null pointer when SOAPAction is ""
------------------------------------------------------
Key: AXIS2-1124
URL: http://issues.apache.org/jira/browse/AXIS2-1124
Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Components: core
Environment: Java 1.4.2, Tomcat 4, Axis 2 nightly build from 9/7/2006
Reporter: Todd Doolittle
Priority: Blocker
This problem occurs with the latest nightly build.
In issue 1103 a bug was fixed that was causing a SOAP client to set the
SOAPAction header to the operation name even though the WSDL used to create the
stub specified that the SOAPAction was to be "" (empy string). This worked and
now when the WSDL specifies a SOAPAction of "", the client sets the header
appropriately.
However now an Axis 2 service generated from the same WSDL receiving a message
with a SOAPAction of "" throws a null pointer exception. To illustrate the
problem I created some simple WSDL for an "echo" service that specifies a
soapaction="". If you use the latest nightly build to generate a service and
client from the WSDL and don't change anything else you should receive an
UnsupportedOperationException thrown by the skeleton since you never
implemented the business logic. Instead when the service receives the SOAP
message, it will puke on the empty SOAPAction header and throw a
NullPointerException. Below is the WSDL. Below that is a stack trace.
