WS invocation over java transport issue

[Gross Julia <ju...@kapsch.net>]

Hi all,

I'm trying to understand how java transport works.
Till now I couldn't quite figure it out. Does anybody know if this
transport is supported, how to use it,
and if there are any samples/documentation concerning this issue?

I'm trying to invoke the stock service that runs on axis 1.3, tomcat
5.x. But I get a NullPointerException...
Could anybody please help me to understand where is the problem? 

Here is my client-config.wsdd

<deployment xmlns="http://xml.apache.org/axis/wsdd"
            xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"
         <transport name="java"
pivot="java:org.apache.axis.transport.java.JavaSender"/>
</deployment>

Here is my java client code:
String symbol = "XXX";
		Service  service = new Service(new
XMLStringProvider(wsdd));
		
        Call     call    = (Call) service.createCall();
        Call.setTransportForProtocol("java", JavaTransport.class);
        
 
call.setTargetEndpointAddress("java:///urn:xmltoday-delayed-quotes");
        call.setOperationName( new QName("urn:xmltoday-delayed-quotes",
"getQuote") );
        call.addParameter( "symbol", XMLType.XSD_STRING,
ParameterMode.IN );
        call.setReturnType( XMLType.XSD_FLOAT );
        call.setTransport( new JavaTransport() );
        
        Float res = new Float(0.0F);
        res = (Float) call.invoke( new Object[] {symbol} );

And here is the exception I get:

java.lang.NullPointerException

        ... 6 more

I guess, the service url is of wrong format. I use:
java:///urn:xmltoday-delayed-quotes
Does anybody know what URL format is expected to address a web service
over java transport?

Thanks a lot in advance!
