How to Schema Validate Metro SOAP Request

@SchemaValidation does the trick checkout the sample code below

package com.palm.appstore.wsc;


import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import com.sun.xml.ws.developer.SchemaValidation;

/**
*
* @author Intesar Mohammed
*/
@WebService(serviceName = "Echo")
@SchemaValidation
public class Echo {

    /** This is a sample web service operation */
    @WebMethod(operationName = "hello")
    public String hello(@WebParam(name = "no") int txt) {
        return "Hello " + txt + " !";
    }
}
