Cool Features of Web Services in the Java SE 6 Platform

I tried Java SE 6 webservices today by turning an existing class into webservice and it worked perfectly fine. I got it done both, manually and also using NetBeans 5.5. Watch out for annotation @WebService. If you selectively want to put methods as web services, you could as well use @WebMethod annotation. This is one cool feature thats coming in java se 6.

 

package generalproj;

import javax.jws.WebService;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;
import javax.xml.ws.Endpoint;

@WebService
public class GeneralClass {
   
    public GeneralClass() {
    }
           
    public void writeToFile( String a_file, String a_content ) {
        if( a_file != null && a_content != null ) {
            try {
                FileOutputStream l_fos = new FileOutputStream( new File( a_file ));
                byte[] l_bytes = a_content.getBytes();
                l_fos.write( l_bytes, 0, l_bytes.length );
                l_fos.close();
            } catch( IOException iox ) {
                iox.printStackTrace();
            }
        }
    }
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {       
        Endpoint.publish(
         "http://localhost:8077/generalproj/GeneralClass",
         new GeneralClass());

    }  
}
