[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Re: Problem by using Tomcat (web) to access JBoss (app)

Mon May 12 06:34:01 EDT 2008

The JSP looks as follow:

  | ...
  | <%@ page
  | 	import="javax.naming.*,java.text.*,java.util.*,com.wei.chen.ejbs.stateless.*,com.wei.chen.ejbs.entity.*"%>
  | 
  | <%!private Calculator cal = null;
  | 	private NumberFormat nf = null;
  | 
  | 	public void jspInit() {
  | 		try {
  | 			InitialContext ctx = new InitialContext();
  | 			cal = (Calculator) ctx.lookup("EntityCalculator/remote");
  | 		} catch (Exception e) {
  | 			e.printStackTrace();
  | 		}
  | 
  | 		nf = NumberFormat.getInstance();
  | 		nf.setMaximumFractionDigits(2);
  | 	}%>
  | 
  | <%
  | 	if ("AddFund".equals(request.getParameter("action"))) {
  | 		cal.addFund(request.getParameter("fundname"), Double
  | 				.parseDouble(request.getParameter("fundrate")));
  | 	}
  | %>
  | 
  | <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  | <title>Insert title here</title>
  | </head>
  | <body>
  | <p>Add a new Fund:<br />
  | <form action="addfund.jsp" method="POST">Fund Name : <input
  | 	type="text" name="fundname" value=""> Growth rate : <input
  | 	type="text" name="fundrate" value="0.05"><input type="hidden"
  | 	name="action" value="AddFund"><br />
  | <input type="submit" value="Add fund"><INPUT type="button"
  | 	value="Close Window" onClick="window.close()"></form>
  | <br />
  | 
  | <%
  | 	 Collection <Fund> funds = cal.getFunds();
  | 
  | %>
  | ...
  | 

I get more info for the exception from the CMD-Console as follow:

That means the stateless session bean "EntityCalculator.java" is not bound successfully from Tomcat to JBoss.

Somebody has experience?
