ciao
i used to access a remote ejb from a servlet.
put the home and remote in the -cp java option
> java -cp .....\orion.jar;.....yourhomeremote
com.evermind.server.ApplicationServer
code like this.
the servlet:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.net.*;
import javax.naming.*;
import javax.rmi.*;
public class MyServlet extends HttpServlet
{
private static final String CONTENT_TYPE = "text/html";
public void init(ServletConfig config) throws ServletException
{
super.init(config);
}
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException
{
Context context = null;
Hashtable env = new Hashtable();
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
//env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "paolo");
env.put("java.naming.provider.url", "ormi://localhost:23791/ejb2");
//env.put(Context.PROVIDER_URL, "ormi://localhost:23791/ejb1");
env.put("java.naming.factory.initial",
"com.evermind.server.rmi.RMIInitialContextFactory");
env.put("dedicated.connection" ,"true");
try
{
out.println("EJBCellerServlet before context");
context = new InitialContext (env);
//context = new InitialContext ();
out.println("EJBCallerServlet after context");
}
catch(Exception e)
{
e.printStackTrace();
}
try {
out.println("EJBCellerServlet before lookup");
// MySessionEJBHome home =
(MySessionEJBHome)context.lookup("MySessionEJB");
Object objref = context.lookup("MySessionEJB1");
// Object objref =
context.lookup("java:comp/env/ejb/MySessionEJB1Home");
out.println("EJBCellerServlet after lookup");
out.println("EJBCellerServlet before cast");
MySessionEJB1Home home =
(MySessionEJB1Home)PortableRemoteObject.narrow(objref,
MySessionEJB1Home.class);
out.println("EJBCellerServlet after cast");
MySessionEJB1 hello = home.create();
} catch (Exception e) {
e.printStackTrace(out);
}
//response.setContentType(CONTENT_TYPE);
//PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head><title>CallerServlet</title></head>");
out.println("<body>");
out.println("<p>The servlet has received a GET. This is the
reply.</p>");
out.println("</body></html>");
out.close();
}
}
and the web.xml file:
<?xml version = '1.0' encoding = 'UTF-8'?>
