Subject [jira] Commented: (AXIS2-1124) Axis servlet throws null pointer when SOAPAction is ""

Todd Doolittle commented on AXIS2-1124:
---------------------------------------


Deepal,

I just downloaded the latest night release of the libraries and axis.war and I get the same
results (NullPointerException) as above.   Below I went through the steps I used to recreate
the problem.  I know it's related to the SOAPAction being "".  If I change the WSDL so that
the client will send a SOAPAction other than "" it works fine.

I used the above WSDL.  I used the following command to create the service...
WSDL2Java -ss -sd -uri test.wsdl -o .

I used the following command to create the client...
WSDL2Java -s -uri test.wsdl -o .

I created a client class to instantiate the stub and make the call:
import org.tempuri.EchoStub;
import org.tempuri.EchoStub.EchoedString;
import org.tempuri.EchoStub.StringToEcho;

public class Axis2ClientTest
{

    public static void main(String[] args) throws Exception
    {
        EchoStub echo = new EchoStub("http://localhost:8090/axis2/services/Echo");

        StringToEcho myString = new StringToEcho();
        myString.setStringToEcho("Hello There!");
        EchoedString returnString = echo.echoString(myString);
        System.out.println("returnString = " + returnString.getEchoedString());
        
    }
}

I deployed the service to Tomcat 4 (using the latest nightly build axis.war).

When I run the client I the following Envelope is send from the client to the service...
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Header />
  <soapenv:Body>
    <ns1:StringToEcho xmlns:ns1="http://tempuri.org/">Hello There!</ns1:StringToEcho>
  </soapenv:Body>
</soapenv:Envelope>


The client receives an Axis Fault which contains the NullPointerException that occured in
the Axis Servlet.  The stack trace is show below...

>             Project: Apache Axis 2.0 (Axis2)
>          Issue Type: Bug
>          Components: core
>         Environment: Java 1.4.2, Tomcat 4, Axis 2 nightly build from 9/7/2006
>            Reporter: Todd Doolittle
>         Assigned To: Deepal Jayasinghe
>            Priority: Blocker

> This problem occurs with the latest nightly build.
> In issue 1103 a bug was fixed that was causing a SOAP client to set the SOAPAction header
to the operation name even though the WSDL used to create the stub specified that the SOAPAction
was to be "" (empy string).  This worked and now when the WSDL specifies a SOAPAction of "",
the client sets the header appropriately.
> However now an Axis 2 service generated from the same WSDL receiving a message with a
SOAPAction of "" throws a null pointer exception.  To illustrate the problem I created some
simple WSDL for an "echo" service that specifies a soapaction="".  If you use the latest nightly
build to generate a service and client from the WSDL and don't change anything else you should
receive an UnsupportedOperationException thrown by the skeleton since you never implemented
the business logic.  Instead when the service receives the SOAP message, it will puke on the
empty SOAPAction header and throw a NullPointerException.  Below is the WSDL.  Below that
is a stack trace.
