Problem

Configured Tomcat to support SSL and deployed this simple hello world web service. And use following client connect to the deployed web service over SSL connection :

package com.mkyong.client;
 
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
 
import com.mkyong.ws.HelloWorld;
 
public class HelloWorldClient{
 
	public static void main(String[] args) throws Exception {
 
	URL url = new URL("https://localhost:8443/HelloWorld/hello?wsdl");
        QName qname = new QName("http://ws.mkyong.com/", "HelloWorldImplService");
 
        Service service = Service.create(url, qname);
        HelloWorld hello = service.getPort(HelloWorld.class);
        System.out.println(hello.getHelloWorldAsString());
 
    }
}

It hits “No name matching localhost found” exception :

Caused by: javax.net.ssl.SSLHandshakeException: 
    java.security.cert.CertificateException: No name matching localhost found
	at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Alerts.java:174)

	......

Solution

This problem and solution is well explained in this article, you can use a Transport Security (SSL) Workaround for your “localhost” development environment.

To fix it, add a javax.net.ssl.HostnameVerifier() method to override the existing hostname verifier like this :

package com.mkyong.client;
 
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
 
import com.mkyong.ws.HelloWorld;
 
public class HelloWorldClient{
 
	static {
	    //for localhost testing only
	    javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
	    new javax.net.ssl.HostnameVerifier(){
 
	        public boolean verify(String hostname,
	                javax.net.ssl.SSLSession sslSession) {
	            if (hostname.equals("localhost")) {
	                return true;
	            }
	            return false;
	        }
	    });
	}
 
	public static void main(String[] args) throws Exception {
 
	URL url = new URL("https://localhost:8443/HelloWorld/hello?wsdl");
        QName qname = new QName("http://ws.mkyong.com/", "HelloWorldImplService");
 
        Service service = Service.create(url, qname);
        HelloWorld hello = service.getPort(HelloWorld.class);
        System.out.println(hello.getHelloWorldAsString());
 
    }
}

Output

Hello World JAX-WS

It’s working fine now.
