Cannot acquire InitialContext from a Servlet
I have the following servlet wich arises a NamingException when calling the instruction InitialContext ctx = new InitialContext(jndiProps);
package ejbfrompojoweb;
import java.io.IOException;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import ejbfrompojo.EjbInheritedFromPojoMath;
@WebServlet("/EjbFromPojo")
public class EjbInheritedFromPojoServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
EjbInheritedFromPojoMath ejbMath = null;
try {
Properties jndiProps = new Properties();
jndiProps.put("java.naming.factory.initial", "org.jboss.naming.remote.client.InitialContextFactory");
jndiProps.put("java.naming.provider.url","remote://localhost:4447");
jndiProps.put("jboss.naming.client.ejb.context", true);
jndiProps.put(Context.SECURITY_PRINCIPAL,"userid");
jndiProps.put(Context.SECURITY_CREDENTIALS, "password");
InitialContext ctx = new InitialContext(jndiProps);
ejbMath = (EjbInheritedFromPojoMath)ctx.lookup(
"EJBInheritedFromPOJO_JB/EjbInheritedFromPojoBean!ejbfrompojo.EjbInheritedFromPojoMath");
} catch (NamingException e) {
e.printStackTrace();
}
request.setAttribute("ejbMath", ejbMath);
request.getRequestDispatcher("/EJBFunctionsResults.jsp").forward(request,response);
}
}
This is the exeption log:

The same code executed from a standalone client works fine.
I tried to see a lot of Internet sites to find a solution, but uselessly.
I am working with JBoss AS 7 in Eclipse IDE.
Can someone help me? Thank you very much
