Hi All,

I'm posting this to this group because you guys seem to be across Axis and I didn't get a response from anyone in the axis-user group.  If this is bad form, then I apologise in advance, but I'm really stuck here!

Any help at all would be greatly appreciated...

Regards,

Neil Brennan

Subject: RPC problems?

Hi,

I'm using what I believe to be the latest version of AXIS on Linux (I downloaded "xml-axis-rc1-bin.zip" yesterday) and trying to talk to a Borland SOAP server with 5 different services.  I'm having very weird problems with it.

I originally started using Apache SOAP, hand-building all the complex classes I wanted to pass around.  Then I discovered WSDL2Java and used it to generate all the classes I need.  I implemented one interface fully to a single service without a hitch.  This wasn't just a 'vanilla' service, it had plenty of beans being passed around and seemed to work perfectly.

Then I tried to move onto the next service.

Here is the WSDL of the second service: http://tims.moveyourselftrailer.com.au:8000/scripts/SackTruck.dll/wsdl/ISackTruck

I used this snippet of code to try and access the simplest of the ports, just as I did previously for the other service:

	ISackTruckservice locator = new ISackTruckserviceLocator();
	ISackTruck client = locator.getISackTruckPort();
	Object fees = client.getSackTruckFees();

And got:

        at com.touchcorp.remote.party.ISackTruckService.main(ISackTruckService.java:133)

But, if I go back and use Apache SOAP directly, everything seems to work just fine.  I am *not* using an operation style of "rpc" when I call via SOAP directly.  My code looks more like this:

	URL url = new URL(locator.getISackTruckPortAddress());
	String uri = "urn:uSackTruckFee";
	String method = "getSackTruckFees";
	Class type = com.touchcorp.soap.isacktruck.TSackTruckFeeInfo.class;
	Vector args = new Vector();

	// get short version of type class name
	String typeName = type.getName();
	int index = typeName.lastIndexOf(".");
	if (index > 0)
	    typeName = typeName.substring(index+1);

	// set up bean mappings
	SOAPMappingRegistry registry = new SOAPMappingRegistry();
    	BeanSerializer serializer = new BeanSerializer();
	registry.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(uri, typeName), type, serializer, serializer);

	// build the call
	Call call = new Call();
	call.setSOAPMappingRegistry(registry);
	call.setTargetObjectURI(uri);
	call.setMethodName(method);
	call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
	call.setParams(args);

	// make the call
	Response response = call.invoke(url, "");

Help!

I have attached some of the relevant WSDL2Java-generated code below.  Any assistance at all would be appreciated greatly.  This is the most common error I am seeing with AXIS, and I get it with almost every method I try, but I am also getting many other equally strange errors to do with serializers, out-of-range errors and other things.  One at a time.

Regards,

Neil Brennan
