I deployed example ear file in JBoss, Jboss gave class cast exception- portable remote object.
I am using RHEL 4
my profram is like this downloaded from net, example3.ear from roseindia.net. The code is like this
bean:
public class MyTestSessionBean
implements SessionBean
{
public void ejbCreate()
throws
CreateException
{
}
public String SayHello(){
String msg="Hello! I am Session Bean";
System.out.println(msg);
return msg;
}
public void setSessionContext( SessionContext aContext )
throws EJBException
{
}
public void ejbActivate()
throws EJBException
{
}
public void ejbPassivate()
throws EJBException
{
}
public void ejbRemove()
throws EJBException
{
}
}
servlet:
package test.session;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import javax.naming.*;
import javax.rmi.PortableRemoteObject;
public class SessionTestServlet extends HttpServlet {
MyTestSessionHome testSessionBean;
public void init(ServletConfig config) throws ServletException{
//Look up home interface
try {
InitialContext ctx = new InitialContext();
Object objref = ctx.lookup("ejb/test/MyTestSessionBean");
testSessionBean = (MyTestSessionHome)PortableRemoteObject.narrow(objref, MyTestSessionHome.class);
} catch (Exception NamingException) {
NamingException.printStackTrace();
}
}
public void doGet (HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
PrintWriter out;
response.setContentType("text/html");
String title = "EJB Example";
out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello World Servlet!</title>");
out.println("</head>");
out.println("<body>");
out.println("<p align=\"center\"><font size=\"4\" color=\"#000080\">Servlet Calling Session Bean</font></p>");
try{
MyTestSession beanRemote;
beanRemote = testSessionBean.create();
out.println("<p align=\"center\"> Message from Session Bean is: <b>" + beanRemote.SayHello() + "</b></p>");
beanRemote.remove();
}catch(Exception CreateException){
CreateException.printStackTrace();
}
out.println("<p align=\"center\"><a href=\"javascript:history.back()\">Go to Home</a></p>");
out.println("</body>");
out.println("</html>");
out.close();
}
public void destroy() {
System.out.println("Destroy");
}
}
