Axis2 Rampart客户端“安全命名空间为空”异常

Question

This is the exception that I am seeing when I try to consume a webservice.

java.lang.RuntimeException: Undefined 'Security policy namespace cannot be null.' resource property

This is how I am engaging rampart.

ConfigurationContext serviceContext = ConfigurationContextFactory.createConfigurationContextFromFileSystem("/usr/axis2-1.6.0/repository", "/usr/axis2-1.6.0/conf/axis2.xml");
EloquaStub serviceStub = new EloquaStub(serviceContext, "<Link to the WSDL>");


ServiceClient client = serviceStub._getServiceClient();
client.engageModule("rampart");
Options options = client.getOptions();              
options.setUserName("<USERNAME>");
options.setPassword("**<PASSWORD>**");

RetrieveResponse retrieveResp = serviceStub.retrieve(retrieveData); //this where I am trying to consume to webservice.

I verified the path to axis2.xml and the repository. The following have been installed.

rahas-1.6.0.mar
rampart-1.6.0.mar

The code can find the above two files along with other modules. The permissions are set correctly. I know this because I do not see a "FileNotFound" exception.

I have set AXIS2_HOME path in the environment.

My questions are as follows.

• What does the exception message mean?
• How to resolve this issue?

Answer 1

This error was because of classpath not being set correctly. I had two folders with similar axis jars. For some reason tomcat was in a weird state when this happen. I removed the the second folder from the classpath and it resolved itself.
