javax.naming.NameNotFoundException

[Somnath Mallick]

Hi Everyone,


I am trying to call an EJB (running on JBOSS 6.0.0-M3) from a Servlet (running on Tomcat 6.0) but i am getting the following error:

 javax.naming.NameNotFoundException: PercentageBean not bound

I have configured everything properly, added all the JAR's. My servlet code is:

package com.test.sendData;

import java.io.IOException;
import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.test.ejbHandler.PercentageRemote;

/**
 * Servlet implementation class SendData
 */
public class SendData extends HttpServlet {
	private static final long serialVersionUID = 1L;


	/**
	 * @see HttpServletdoPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
	{
		try 
		{
			String name = request.getParameter("name");
			int rollNo = Integer.parseInt(request.getParameter("rollno"));
			float engScore = Float.parseFloat(request.getParameter("engScore"));
			float hindiScore = Float.parseFloat(request.getParameter("hindiScore"));
			float mathsScore = Float.parseFloat(request.getParameter("mathsScore"));
			float scienceScore = Float.parseFloat(request.getParameter("sciScore"));

			Hashtable<String, String> environment = new Hashtable<String, String>();
			environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
			environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");
			environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

			PercentageRemote percentageRemote = null;
			Context initial = null;

			initial = new InitialContext(environment);
			percentageRemote = (PercentageRemote) initial.lookup("PercentageBean/remote");

			float percentage = percentageRemote.getPercentage(engScore, hindiScore, mathsScore, scienceScore);

			request.setAttribute("name", name);
			request.setAttribute("rollno", rollNo);
			request.setAttribute("percentage", percentage);
			RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("jsp/percentageResults.jsp");
			dispatcher.forward(request,response);
		} 
		catch(NamingException e) 
		{
			e.printStackTrace();
		} 
	}
}

Please help!!!

What jndi-name(s) does the JNDIView MBean from the jmx-console show for your beans? Use the list() operation on that MBean to display the JNDI tree.

[Somnath Mallick]

Well when i opened the JNDIView, and opened list(), i didn't find any JNDI Name which starts with the name of "Percentage" or should i be looking for something else. Also I found some errors, on the page as well.

com.arjuna.ats.internal.jbossatx.jta.PropagationContextManager)
  +- app (class: javax.naming.Context)
Failed to lookup: app, errmsg=java:app not supported by legacy component null

Failed to lookup: timedCacheFactory, errmsg=org.jboss.util.TimedCachePolicy cannot be cast to javax.naming.NamingEnumeration

[rajan patil]

While your application server (JBoss) getting started, you can see that your EJB getting bound to jndi name on console(or in server.log).
From exception it seems that your EJB is not registered with jndi.

I have finally got rid of the Naming Exceptions. But now when I run the servlet I get a whole set of other exceptions:

Even googling didn't help much on this!
