Axis2 Client exception: java.lang.IllegalArgumentException: Null OutputStream specified

I am using Axis2 to write a Client for a Webservice hosted on a remote server:

public static void getUserProfile(
        final VSIUserServiceDetailsWebService_v5R0Stub stub) {
    try {
        final GetUserProfileByVOLNameDocument reqDoc =
                GetUserProfileByVOLNameDocument.Factory.newInstance();
        final GetUserProfileByVOLNameDocument.GetUserProfileByVOLName req =
                reqDoc.addNewGetUserProfileByVOLName();
        req.setString("resc3ofw");

        LOG.debug("Invoking Web service...");
        final GetUserProfileByVOLNameResponseDocument res =
                stub.getUserProfileByVOLName(reqDoc);

        LOG.debug("Output: "
                + res.getGetUserProfileByVOLNameResponse().getResult()
                .getUserProfiles().getId());
    } catch (final Exception e) {
        LOG.error("Error! : ", e);
    }
}

and I am getting an Exception "java.lang.IllegalArgumentException: Null OutputStream specified" Following is the complete trace of the log:

I have figured out myself what the issue was.

First I should extend

org.apache.axis2.transport.CommonsHTTPTransportSender

class instead of implementing

org.apache.axis2.transport.TransportSender

and then provide

super.invoke

in the overrridden invoke method to allow super class to handle the flow (Null outputstream error thrown becuase of the omission of this line).

I encountered the same error and it took a few days to get it resolved. To fix the problem I had to use the correct mix of dependencies in my pom.xml. Here is what I used that actually worked. Unfortunately, I had to use a slightly older version of some APIs:

I got the same exception when deploying an AMP to Alfresco. The code ran fine locally, but not when deployed in Alfresco. Turns out Alfresco already included its own version of the Axiom JARs. The version Alfresco uses is 1.2.5 and changing this to 1.2.7 solves the problem.
