[jboss-user] [Beginners Corner] - error on accessing a web-service

Sun Mar 2 11:16:20 EST 2008

Hello, i have an ejb which contains following java-class "JBossEJBWS.java"

package org.me.ejbwss;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.ejb.Stateless;

@Stateless
@WebService
public class JBossEJBWS {
	private String message = new String("Hello, ");

    @WebMethod
    public String greet(String name) {
        return message + name + ".";
    }
}

when i deploy it, i can access the wsdl-file: 
http://localhost:8080/WSEJBModule/JBossEJBWS?wsdl

Now i want to create a war-file which contains a jsp-file, which executes the method "greet"
For this i created web.xml in WEB-INF:

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    version="2.5" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <display-name>webclient</display-name>

        <display-name>greeting</display-name>
        <servlet-name>greeting</servlet-name>
        <jsp-file>/index.jsp</jsp-file>

    <servlet-mapping>
        <servlet-name>greeting</servlet-name>
        <url-pattern>/greeting</url-pattern>
    </servlet-mapping>
    <service-ref>
     	<service-ref-name>services/JBossEJBWS</service-ref-name>
        <service-interface>javax.xml.ws.Service</service-interface>
        <wsdl-file>WEB-INF/wsdl/JBossEJBWS.wsdl</wsdl-file>
        <port-component-ref>
       		<service-endpoint-interface>org.me.ejbwss.JBossEJBWS</service-endpoint-interface>
     	</port-component-ref>
  	</service-ref>
</web-app>

And this is the jsp-file:

<%@page contentType="text/html"%>
            <%@page pageEncoding="UTF-8"%>
            <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
               "http://www.w3.org/TR/html4/loose.dtd">
            <%@ page language="java" import="java.util.*" %>
			<%@ page import="java.io.*,javax.naming.InitialContext,javax.xml.ws.Service,org.me.ejbwss.JBossEJBWS"%>

                    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
                    JSP Page

                <h1>JSP Page</h1>

                <%
                try {out.println("ole");
            		InitialContext ctx = new InitialContext();
		            Service service = (Service)ctx.lookup("java:comp/env/services/JBossEJBWS");
            		JBossEJBWS port = (JBossEJBWS) service.getPort(JBossEJBWS.class);         
                } catch (Exception e) {
					out.println("Error: " + e.getMessage());
                }
                String text = port.greet("Fugee");
            	out.println(text);
                %>

The Problem is, when i open the URL (http://localhost:8080/WSCWebModule/) in a webbrowser, i get the following error:

org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 23 in the jsp file: /index.jsp
port cannot be resolved
20:                 } catch (Exception e) {
21: 					out.println("Error: " + e.getMessage());
22:                 }
23:                 String text = port.greet("Fugee");
24:             	out.println(text);
25:                 %>
26:
