Problem consuming ABAP Web Service using SAP MESDK

[Former Member]

I am having trouble consuming an ABAP Web Service from JAVA using the SAP ME (Manufacturing Execution) SDK. I created a very simple un-authenticated web service that takes a string an input and returns the same string in reverse order. I have setup the service and created the endpoints in SOAMANAGER. I can call the web service from SOAPUI and .Net. When I attempt to use the MESDK (in eclipse) to generate the JAVA class, I need to change the namespace in the WSDL generated by sap from urn:sap-com:document:sap:soap:functions:mc-style to something the MESDK requires. The targetNamespace for MESDK is required to be of the format http://<vendor>.com/ServiceName. In my case, http://y12me.com/zspub_ReverseHTTP. When I attempt to use the web service via the generated Java proxy (I believe ME is using the standard JAX and eclispe tools but my Java is weak), I get the following error:

Virtual Interface Method >ZsReverse::http://y12me.com/zspub_ReverseHTTP< not supported

This makes sense, because the method namespace in SAP is urn:sap-com:document:sap:soap:functions:mc-style.

So, what I assume I need to do is to override the either the targetNamespace in JAVA or change the SOAP namespace in SAP. I started with SAP as that is where I am most familiar. I cannot find anywhere that I can modify the SOAP Namespace. It is not an input field on the wizard when I generated the proxy class and it is not an editable field on the service definition. I found a reference in the old NW04 help files that shows how to define a virtual interface in the wizard at runtime but those options are not available on my ECC 6.0 (ep4) system.

In looking at the JAVA, the code is very simple but I cannot see any methods or attributes that will alter this. The code is very simple:

ZsPubReversePlain ws = new ZsPubReversePlain();

ZSPUBREVERSEWS myPort = ws.getZsPubReversePlainBinding();

Map<String, Object> ctx = ((BindingProvider) myPort).getRequestContext();

ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, ".../zspubreverseplain/zspubreverseplainbinding");

String out = myPort.zsReverse("Testing");

The code above gives the previously mentioned error. I also get the same error in SOAPUI if I change the namespace in the XML to the http://y12me.com/.

The only other options on the BindingProvider are URI_PROPERTY and USE_PORPERTY. I tried the following to see if that would override but got the same error.

ctx.put(BindingProvider.SOAPACTION_URI_PROPERTY, "ZsReverse::sap-com:document:sap:soap:functions:mc-style");

ctx.put(BindingProvider.SOAPACTION_USE_PROPERTY, Boolean.TRUE.toString());

Any help from either end, changing the SOAP Namespace in ECC or overriding the WSDL namespace at runtime from Java would be greatly appreciated.

Thanks in advance - Michael

My error. I needed to generate the WSDL with different parameters from the R/3 side to get one that is JAX-WS compliant.
