---------------------------------------------
Hi Kishanthan,
I have run into a similar issue (I am using the
createBasicConfigurationContext(MY_RESOURCE)). But I still don't understand the
solution. What are those methods for if they cannot be used? What shall I use
instead?
Thanks
Magda
> 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: 1.6.0, 1.6.1, 1.6.2
> Environment: Any. Testing on Windows 7 with java 1.5.
> Reporter: Barry Tarlton
> Assignee: Kishanthan Thangarajah
> Priority: Critical
> Labels: nullpointer, transport
> Fix For: 1.5.6
>
>
> Something has changed from 1.5.6 to 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.
