hi partha,
my problem is not like this,calling get and post methods of servlets
from jsps are working.
this is not my problem.my problem is calling other than get,post methods.
i am sending some sample code.
Servlet1.java
-------------------
import java.io.*;
import javax.servlet.http.*;
import javax.servlet.*;
public class Servlet1 extends HttpServlet{
public void doGet(HttpServletRequest req,HttpServletResponse
res)throws ServletException,IOException{
PrintWriter out=res.getWriter();
out.println("Hello this is Servlet1.....");
getServletConfig().getServletContext().setAttribute("add",this);
}
public int add(int a,int b){
return a+b;
}
}
Servlet2.java
------------------
import java.io.*;
import javax.servlet.http.*;
import javax.servlet.*;
public class Servlet2 extends HttpServlet{
public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException{
PrintWriter out=res.getWriter();
out.println("Hello i am Servlet2...");
Servlet1
s=(Servlet1)(getServletConfig().getServletContext().getAttribute("add"));
int a=s.add(4,5);
out.println("the result is:"+a);
}
}
these 2 are working fine.2nd servlet displaying the result.
*insteadof 2nd servlet i want jsp.*
*plz. help me for this.*
thanks in advance

Hi,
There are two ways of calling a servelt method from a jsp:
1. for any public method on the servlet, you can call getServlet()
from
the JSP for any servlet within the same container specifying the
name of the
servlet as specified in the web.xml. This will however bypass the
http call
interposition that is done by the container and you are
responsible for any
synchronisation or any call interposition requirement. Not
recommended.
2. You can make a URLConnection to the servlet from your JSP and call
doGet() or doPost(). The logic should be there in these two methods.
Of course, you can use request dispatcher for mundane uses.
Hope this helps.
Regards,
Partha

To send the call to the servlet page:
1.In your jsp page, put
-->"aa" servlet's doPost() method
will be
called. From here you can direct the call to different places
or
2. You can include java beans in the jsp page using->
and you can call methods on this included bean
${bean.property}
You can also check:

hope this is what you are asking for..
