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