Hi Friend,

Put your html file in web application folder and servlet in classes folder of apache tomcat. The web application folder should be under webapps folder of apache tomcat. Here examples is our web application folder.

1)index.html:

<HTML>
<FORM method="post" action="http://localhost:8080/examples/ServletExample">;
<TABLE>
<TR><TD>Name:</TD><TD><input type="text" name="name"></TD></TR>
<TR><TD>Address:</TD><TD><input type="text" name="address"></TD></TR>
<TR><TD><input type="submit" name="Submit"> </TD></TR>
</FORM>
</HTML>

2)ServletExample.java:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class ServletExample extends HttpServlet{
public void doPost(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException{
res.setContentType("text/html");
PrintWriter out=res.getWriter();
String name=req.getParameter("name");
String address=req.getParameter("address");
out.println(name);
out.println(address);
}
}

3)In web.xml do the following:

<servlet>
<servlet-name>ServletExample</servlet-name>
<servlet-class>ServletExample</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ServletExample</servlet-name>
<url-pattern>/ServletExample</url-pattern>
</servlet-mapping>
