[nobr]What exactly are you trying to achieve?

This is a typical servlet with raw html. You can also put javascript there the same way html is there.

public class FirstServlet extends HttpServlet {

public void doGet(HttpServletRequest request,

HttpServletResponse response) throws ServletException,

java.io.IOException {

//set the MIME type of the response, "text/html"

response.setContentType("text/html");

//use a PrintWriter to send text data to the client who has requested the

//servlet

java.io.PrintWriter out = response.getWriter( );

//Begin assembling the HTML content

out.println("<html><head>");

out.println("<script language='javascript'>alert('Hello Muthu');</script");

out.println("><title>Help Page</title></head><body>");

out.println("<h2>Please submit your information</h2>");

//make sure method="post" so that the servlet service method

//calls doPost in the response to this form submit

out.println(

"<form method=\"post\" action =\"" + request.getContextPath( ) +

"/firstservlet\" >");

out.println("<table border=\"0\"><tr><td valign=\"top\">");

out.println("Your first name: </td> <td valign=\"top\">");

out.println("<input type=\"text\" name=\"firstname\" size=\"20\">");

out.println("</td></tr><tr><td valign=\"top\">");

out.println("Your last name: </td> <td valign=\"top\">");

out.println("<input type=\"text\" name=\"lastname\" size=\"20\">");

out.println("</td></tr><tr><td valign=\"top\">");

out.println("Your email: </td> <td valign=\"top\">");

out.println("<input type=\"text\" name=\"email\" size=\"20\">");

out.println("</td></tr><tr><td valign=\"top\">");

out.println("<input type=\"submit\" value=\"Submit Info\"></td></tr>");

out.println("</table></form>");

out.println("</body></html>");

}//doGet

public void doPost(HttpServletRequest request,

HttpServletResponse response) throws ServletException,

java.io.IOException {

//display the parameter names and values

Enumeration paramNames = request.getParameterNames( );

String parName;//this will hold the name of the parameter

boolean emptyEnum = false;

if (! paramNames.hasMoreElements( ))

emptyEnum = true;

//set the MIME type of the response, "text/html"

response.setContentType("text/html");

//use a PrintWriter to send text data to the client

java.io.PrintWriter out = response.getWriter( );

//Begin assembling the HTML content

out.println("<html><head>");

out.println("<title>Submitted Parameters</title></head><body>");

if (emptyEnum){

out.println(

"<h2>Sorry, the request does not contain any parameters</h2>");

} else {

out.println(

"<h2>Here are the submitted parameter values</h2>");

}

while(paramNames.hasMoreElements( )){

parName = (String) paramNames.nextElement( );

out.println(

"<strong>" + parName + "</strong> : " +

request.getParameter(parName));

out.println("<br />");

}//while

out.println("</body></html>");

}// doPost

}

Does it hurt if I say that it is a school example of bad design?
