Thank you Jessica!!

How do you search for topic in the forum...? Has the search link been placed elsewhere?

Thanks Bosun....But I guess you have a look at my code and tell me where I am going wrong...coz the Weblogic Server gives me a NullPointerException.
import java.sql.*; import javax.servlet.*; import javax.servlet.http.*; import javax.naming.*; import java.util.*; import java.io.*; public class trials extends HttpServlet { Connection conn=null; Statement st=null; public void init(ServletConfig sc){ try { super.init(sc); Context ctx=null; System.out.println(" Variables Initialized "); Hashtable ht=new Hashtable(); ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); ht.put(Context.PROVIDER_URL,"http://localhost:7001"); System.out.println(" properties put in Hashtable "); ctx=new InitialContext(ht); javax.sql.DataSource ds=(javax.sql.DataSource)ctx.lookup("suneelss"); conn=ds.getConnection(); st=conn.createStatement(); } catch (Exception e) { e.printStackTrace(); } } public void doGet(HttpServletRequest request,HttpServletResponse response) { try { PrintWriter out=response.getWriter(); System.out.println("in service"); int i=10; Integer num=new Integer(i); RequestDispatcher dispatcher=getServletConfig().getServletContext().getRequestDispatcher("http://localhost:7001/trials/try2"); request.setAttribute("cust_id",num); dispatcher.forward(request,response); } catch(Exception e) { e.printStackTrace(); } } }
And this is the error

Hi
Thanks for the replies.
Ben can you give me an example code where I can pass a key & value pair like i=10 to the next servlet?
Bear I hae no difficulties with redirecting. I was wanting to pass a couple of parameters to the next servlet where I indicated that the variable(var)and its value needed to go the next servlet.

When I pass Parameters from one servlet to another using something like response.sendRedirect("http://webserver:7001/......?var=value") I get only the var in the second servlet and not the value. Where am I going wrong? Can you please give me a sample code..

I am told that the MS-IIS can be used to deploy
servlets/JSPs.Refer this article
Can you help me set the classpath for this and also help me deploy a servlet
Thanks

I get the following error when I use the build auto create)option to generate
Deployment Descriptors in Weblogic 7.
"No J2EE components to generate Deployments Descriptors"
Am I missing something?

How do you mask a text field so that ** are shown?
Example a password field.

Hi
Can we not have a client, that is not a servlet, access an EJB method?

Hi Rahul
Redundant is more of one type than is necessary. Something which can do the same work as an extra. Normally redundant servers don't have anything to do unless it has more than normal requests to process and/or there is a breakdown(fails) or load on the regular servers.

All the very Best Rahul !!!
