NPE thrown from OperationClient addMessageContext method after calling reset
method
-----------------------------------------------------------------------------------
Key: AXIS2-3094
URL: https://issues.apache.org/jira/browse/AXIS2-3094
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: kernel
Affects Versions: 1.2
Reporter: Peter Tandara-Kuhns
The reset method of org.apache.axis2.client.OperationClient sets the
OperationContext member variable (oc) to null. There doesn't appear to be any
way to restore this member, and as a result subsequent OperationClient methods
cause NullPointerExceptions to be thrown.
I am creating the OperationClient using the ServiceClient createClient method
with a value of org.apache.axis2.client.ServiceClient.ANON_OUT_IN_OP.
Stack trace:
java.lang.NullPointerException
at
org.apache.axis2.context.ConfigurationContext.registerOperationContext(ConfigurationContext.java:229)
at
org.apache.axis2.description.AxisOperation.registerOperationContext(AxisOperation.java:396)
at
org.apache.axis2.description.OutInAxisOperationClient.addMessageContext(OutInAxisOperation.java:122)
Code fragment:
// First attempt - success
org.apache.axis2.client.ServiceClient svcClient = new
org.apache.axis2.client.ServiceClient();
org.apache.axis2.client.OperationClient opClient =
svcClient.createClient(org.apache.axis2.client.ServiceClient.ANON_OUT_IN_OP);
org.apache.axis2.context.MessageContext msgContext = new
org.apache.axis2.context.MessageContext();
msgContext.setEnvelope(createTestEnvelope());
org.apache.axis2.client.Options options = msgContext.getOptions();
options.setTo(new org.apache.axis2.addressing.EndpointReference(url));
opClient.addMessageContext(msgContext);
opClient.execute(true);
System.out.println("SOAP Response:\n" +
opClient.getMessageContext("In").getEnvelope());
// Second attempt - fail, NullPointerException
opClient.reset();
opClient.addMessageContext(msgContext);
opClient.execute(true);
System.out.println("SOAP Response:\n" +
opClient.getMessageContext("In").getEnvelope());
