Problem with req.getRequestDispatcher

[sam_knightrider]

I have made a index.html file, in which there is option to fill username and password and role(Operator or Administrator).

When we submit this, it goes to login servlet. and if credentials are correct is should redirects to operator.jsp ( If role = operator)..

But it is unable to find this jsp file.

I have put the jsp file in ...\Apache Group\Tomcat 4.1\webapps\ROOT\studio

folder...

I dnt knw y it is unalble to find that file. Please help.

I am also posting Login Servlet code snippet:




public class login extends HttpServlet{

protected void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

res.setContentType("text/html");
PrintWriter out=res.getWriter();
String n=req.getParameter("user");
String p=req.getParameter("pass");
String r=req.getParameter("role");

RequestDispatcher rd=null;
if(n==""||p==""){

rd=req.getRequestDispatcher("studio/index.html");
rd.include(req,res);
out.println("Password Or User Name can't be empty");
}
else
{
Connection con=null;
Connection con1=null;
PreparedStatement pstm=null;
ResultSet rt=null;

try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbcdbc:studio");
}catch(Exception er){
}


try{
pstm=con.prepareStatement("select * from login where name=? and password=? and role=?");

pstm.setString(1,n);
pstm.setString(2,p);
pstm.setString(3,r);

rt=pstm.executeQuery();

System.out.println("query Fired");
if(rt.next()==true){

try{
con1=DriverManager.getConnection("jdbcdbc:studio");
PreparedStatement pstm2=con1.prepareStatement("insert into log (userid,ipadd,logindatetime) values(?,?,?)");
pstm2.setString(1,n);
pstm2.setString(2,req.getRemoteAddr());
Date d=new Date();
pstm2.setString(3,d.toString());
System.out.println("query set");
pstm2.executeUpdate();
pstm2.close();
}catch(Exception e){System.out.println("Error in PS "+e.getMessage());}
System.out.println("values inserted");


if(r.equalsIgnoreCase("Operator")){
rd=req.getRequestDispatcher("operator.jsp");

HttpSession ses=req.getSession(true);
ses.setAttribute("conn",con);
ses.setAttribute("uname",n);

rd.forward(req,res);

}
else
if(r.equalsIgnoreCase("Administrator")){
rd=req.getRequestDispatcher("studio/admin.jsp");

HttpSession ses=req.getSession(true);
ses.setAttribute("conn",con);
ses.setAttribute("uname",n);
rd.forward(req,res);
System.out.println("Administrator passed");
}
rt.close();


pstm.close();




}
else{
rd=req.getRequestDispatcher("studio/index.html");
out.print(" UserName Or Password Invalid");
rd.include(req,res);

}


}catch(SQLException e){}
}

}

}


Please help in this regard...
