Is RPC/Encoded not allowed in JAX-WS?

[Kumar Raja]

Hello All,

I'm trying to learn @SOAPBinding annotations with different options and compare the generated WSDL.

This example is taken from Ivan's notes

   
mport javax.annotation.PostConstruct;
import javax.annotation.Resource;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
import javax.xml.ws.WebServiceContext;

@WebService(
		name="Calculator",
		serviceName="CalculatorService",
		targetNamespace="http://www.ws.learning.com/calculator",
		wsdlLocation="CalculatorService.wsdl"
		)
@SOAPBinding(
		parameterStyle=SOAPBinding.ParameterStyle.WRAPPED,
		style=SOAPBinding.Style.RPC,
		use=SOAPBinding.Use.ENCODED
		)
public class Calculator{
	@Resource
	private WebServiceContext context;
	
	@PostConstruct
	@WebMethod(exclude=true)
	public void init(){
		System.out.println("Initialization of Service");
	}
	
	@WebMethod(operationName="addNumbers", action="urn:Add")
	@ResponseWrapper(
			className = "org.learning.ws.AddResponse",
			localName = "addNumbersResponse",
			targetNamespace = "http://www.ws.learning.com/calculator"
	)

	@RequestWrapper(
			className="org.learning.ws.AddRequest",
			localName="addNumbersRequest",
			targetNamespace="http://www.ws.learning.com/calculator"
	)
	
	public int add(int x,int y){
		System.out.println("Values are being operated");
		return x+y;
	}
	
}
      

I modified Style to RPC and use to ENCODED.

When I try to wsgen, it failed with error message

    
see stacktrace below for more information.
     [exec] com.sun.tools.internal.ws.processor.modeler.ModelerException: modeler error: The org.learning.ws.math4fun.Calculator class has invalid SOAPBinding annotation. rpc/encoded SOAPBinding is not supported

From this, I'm thinking that RPC/Encoded is not permitted though RPC/Literal is.

Is this a change from JAX-RPC? or RPC was never allowed ENCODING.

Can I assume that, through JAX-WS

Only DOCUMENT - LITERAL or RPC - LITERAL are permitted and nothing else.

Environment:

Glassfish v3
JDK 1.6

Please advice.

Hi,

Latest J2EE containters in market are trying to comply with basic profile so they can achieve Interoperability across diffrent platforms. Glassfish is no exception. As per WS basic profile 1.1 RPC/Encoded or Document/Encoded style is not allowed because it is a major source of conflicts. Remember, JAX-RPC is renamed to JAX-WS to avoid confusion created by word RPC in name.

Hope this helps.

Thank you Mark.

Which style of WSDL should I use? says -

Although it is legal WSDL, RPC/encoded is not WS-I compliant.

Excellent article.

Can You please help me out by answering the same Question ?

Can RPC/Encoded be allowed for JAX-WS ?

My WSDL is also using Message Level Security.. Please suggest me best way for client implementation ?
