NullPointerException when generating WSDL for service with an empty
TransportToken policy
-----------------------------------------------------------------------------------------
Key: RAMPART-176
URL: https://issues.apache.org/jira/browse/RAMPART-176
Project: Rampart
Issue Type: Bug
Components: rampart-policy
Reporter: Predrag Knezevic
Assignee: Ruchith Udayanga Fernando
Fix For: 1.4
As the example located in samples/policy/sample01 suggests, the policy of
TransportToken might be empty. Here is the snippet from the service.xml file:
{noformat}
<sp:TransportBinding
xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy";>
<wsp:Policy>
<sp:TransportToken>
<wsp:Policy>
<!-- <sp:HttpsToken
RequireClientCertificate="false"/> -->
</wsp:Policy>
</sp:TransportToken>
<sp:AlgorithmSuite>
<wsp:Policy>
<sp:Basic256/>
</wsp:Policy>
</sp:AlgorithmSuite>
<sp:Layout>
<wsp:Policy>
<sp:Lax/>
</wsp:Policy>
</sp:Layout>
<sp:IncludeTimestamp/>
</wsp:Policy>
</sp:TransportBinding>
{noformat}
Deploying a service with this policy goes fine, and it is available and react
properly, but if you want to get the corresponding WSDL, NullPointerException
is thrown and WSDL is not returned. The exception happens in serialize() method
of TransportToken class, because it is not expected that the policy can be
empty. A simple is fix is necessary, here is the diff:

writer.writeEndElement();
If other tokens allow empty policies as well (I do not know much about the
specification), they should be fixed in the similar way.
