Hi

I am new o EJB
I have created a new EJB app . In EJB module i created a package having one interface and one stateless bean

and exported the jar using the eclispe IDE

Then i deployed the jar in Deploy folder of JBoss

I created one folder named client.war in jBoss deploy directory and created 2 Jsp's there

index.jsp

WebClient.jsp

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page import="com.practise.ejb.*,
 javax.naming.*"%>

<%!
  private CalculatorRemote calculator = null;
  float result=0;

public void jspInit() {
  try {
  
  InitialContext ic = new InitialContext();
   System.out.println("Loadung Calculator Bean <<<<<<<<<<>>>>>>>>>>>>>>>>");
  calculator = (CalculatorRemote) ic
  .lookup("CalculatorBean/remote");

System.out.println("Loaded Calculator Bean <><><><><><><><><><><><><><><><><><><><");
//CalculatorBean

} catch (Exception ex) {
  System.out.println("Error:"+
  ex.getMessage());
  }
  }
  public void jspDestroy() {
  calculator = null;
  }
%>
  <%
  try {
  String s1 = request.getParameter("num1");
  String s2 = request.getParameter("num2");
  String s3 = request.getParameter("group1");

System.out.println("<><><><><>"+s3+"calculator "+calculator);

if ( s1 != null && s2 != null ) {
  Float num1  = new Float(s1);
  Float num2  = new Float(s2);
  
  if(s3.equals("add"))
  result=calculator.add(num1.floatValue(),
num2.floatValue());
  else if(s3.equals("sub"))
  result=calculator.subtract(num1.floatValue(),
num2.floatValue());
  else if(s3.equals("multi"))
  result=calculator.multiply(num1.floatValue(),
num2.floatValue());
  else
  result=calculator.division(num1.floatValue(),
num2.floatValue());
  
 %>
  <p>
  <b>The result is:</b> <%= result %>
  <p>
  
  <%
  }
  }// end of try
  catch (Exception e) {
  e.printStackTrace ();
 //result = "Not valid";
  }
  %>

Its not able to find the Bean

Please let me know if i am going wrong

Thanks In Advance

Hi,

When you deploy the EJB JAR in JBoss, did you see the deployed EJB name on the JBOSS console?
I think there is some issue with the JNDI name with which the EJB is registered on the server.
