------------------------------------
Summary: Creating ServiceClient with ConfigContext created using
createDefaultConfigurationContext() causes NullPointerException
Key: AXIS2-5501
URL: https://issues.apache.org/jira/browse/AXIS2-5501
Project: Axis2
Issue Type: Bug
Components: transports
Affects Versions: 1.6.2, 1.6.1, 1.6.0
Environment: Any. Testing on Windows 7 with java 1.5.
Reporter: Barry Tarlton
Priority: Critical
Fix For: 1.5.6
Something has changed from 1.5.6 and 1.6.0 in the axis2-transport-http.jar that
causes a null pointer exception if you initialize your ServiceClient with an
ConfigurationContext that was created by calling
ConfigurationContextFactory.createDefaultConfigurationContext().
Here's the modified sample that shows the behavior:
public class EchoBlockingClient {
private static EndpointReference targetEPR = new
EndpointReference("http://localhost:8080/checkSoap";);
public static void main(String[] args) throws Exception {
try {
OMElement payload = ClientUtil.getEchoOMElement();
Options options = new Options();
options.setTo(targetEPR);
options.setAction("urn:echo");
// create config using defaultConfigurationContext...
// this does not initialize the transportOutDescription's sender's
transportOut and causes a null pointer
ConfigurationContext defaultContext=
ConfigurationContextFactory.createDefaultConfigurationContext();
// this initializes the transportOut.sender.transportOut properly
and allows it to work.
// ConfigurationContext defaultContext=
ConfigurationContextFactory.createConfigurationContextFromFileSystem(null,
null);
//Blocking invocation
ServiceClient sender = new ServiceClient(defaultContext, null);
sender.setOptions(options);
OMElement result = sender.sendReceive(payload);
System.out.println(result);
} catch (AxisFault axisFault) {
axisFault.printStackTrace();
}
}
I see the following exception when doing so:
Exception in thread "main" java.lang.NullPointerException
at
org.apache.axis2.transport.http.CommonsHTTPTransportSender.invoke(CommonsHTTPTransportSender.java:172)
at org.apache.axis2.engine.AxisEngine.send(AxisEngine.java:443)
This is because the TransportOutDescription is never set on the
CommonHTTPTransportSender.
If I change the code and use the
ConfigurationContext defaultContext=
ConfigurationContextFactory.createConfigurationContextFromFileSystem(null,
null);
Then this code works fine.
I can also, just replace the axis2-transport-http-1.6.0.jar with the
axis2-transport-http-1.5.6.jar and it will work either way.
