Question

I have an interface and a servlet file ,whenever I try to run the application program it gives me following error

SEVERE: Class [ LDir/DirSessionLocal; ] not found. Error while loading [ class DirServlet ]

code for interface

package Dir;

import javax.ejb.Local;


@Local
public interface DirSessionLocal {

String getContact(String name1);

String getDetails(String name2);

void rater(String r);

}

code for servlet

import javax.ejb.EJB;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


@WebServlet(urlPatterns = {"/DirServlet"})
public class DirServlet extends HttpServlet {
@EJB
private DirSessionLocal dirSession;

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    PrintWriter out = response.getWriter();
    try {
        /* TODO output your page here. You may use following sample code. */
        out.println("<!DOCTYPE html>");
        out.println("<html>");
        out.println("<head>");
        out.println("<title>Servlet DirServlet</title>");            
        out.println("</head>");
        out.println("<body>");
        out.println("<h1>Servlet DirServlet at " + request.getParameter("name") + "</h1>");
        out.println("<br>");
        out.println("<h1>" + request.getParameter("nameD") + "</h1>");
        out.println("<br>");
        out.println("<h1>" + request.getParameter("rate") + "</h1>");
        String a=request.getParameter("nameD");
        if(a.equals("abc"))

         out.println("<h1>" + dirSession.getContact(a)  + "</h1>");
        out.println("</body>");
        out.println("</html>");

Answer 1

It means that the JVM running your servlet / webapp cannot find the ".class" file for a class with the name Dir.DirSessionLocal .

Depending on how you are "deploying" your servlet, you either need to add the missing class to a JAR file, an WAR file, the webapp's tree on the web server, etc.
