Java SE 6 Hits the StreetsWeb Services
One of the biggest new features of Java SE 6 is the built-in support for web services. This release introduces JAX-WS version 2.0, which includes the Java API for XML Web Service (JAX-WS), the SOAP with Attachments API for Java (SAAJ), and web services metadata (the javax.jws package). These enhancements make it easier than ever to build web services with Java. For instance, the following class translates into a SOAP-enabled web services:
package salestax;
import java.util.*;
import javax.jws.WebService;
@WebService
public class SalesTax {
private HashMap taxTable = new HashMap();
public double getFinalPrice(String state double price)
{
double tax = taxTable.get(state).doubleValue();
price += (price * (tax/100));
return price;
}
public void static main(String[] args)
{
Javax.xml.ws.Endpoint.publish(
"http://localhost:8080/salesTaxService", new SalesTax);
}
}
To use this service from a Java application, the code looks like the following:
public static void main(String[] args)
{
try {
// Call Web Service
ws.salesTaxService taxService =
new ws.salesTaxService();
ws.SalesTax port = service.getSalesTaxPort();
double price = port.getFinalPrice("New York", args[0]);
System.out.println("Final price = " + price);
}
catch (Exception ex) {
ex.printStackTrace();
}
}
