JAX-WS EJB Endpoint

EJB3.0 specification has made writing web services much easier. You do not even need a web application to host the service. The web services can be hosted in EJB container in an easy way. To write the web service write a Stateless EJB and mark it as Web service

ProductPriceBean.java

@Stateless

@WebService

public class ProductPriceBean {

private Map productMap = new HashMap();

    

    {

        productMap.put("Java","500");

        productMap.put("C++","300");

    }

@WebMethod

public double getPrice(String symbol){

   String price = (String) productMap.get(symbol);

        if(price != null){

            return Double.parseDouble(price);

        }

   return -1;

}

Note that you donot have to write any interface like Local or Remote. Just write this, deploy it as a Jar in your EJB container and hit the ((WSDL)) at:

http://<hostName>/JAX_WS_EJB/ProductPriceBean?wsdl
