java method and servlet
- Thread starter kiki88
- Start date
same way as you'd call any java class method.. after all a servlet is still a java class at the end of the day.
Example:
import javax.servlet.*;
import javax.servlet.http.*;
public class MyServlet extends HttpServlet {
AJavaClass myJavaClass;
/** Initializes the servlet.
*/
public void init(ServletConfig config) throws ServletException {
super.init(config);
myJavaClass = new AJavaClass();
}
/** Destroys the servlet.
*/
public void destroy() {
}
/** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
* @param request servlet request
* @param response servlet response
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
response.setContentType("text/html"
;
java.io.PrintWriter out = response.getWriter();
out.println("<html>"
out.println("<head>"
out.println("<title>Servlet</title>"
out.println("</head>"
out.println("<body>"
out.println("this is my class wossname"+myJavaClass.toString()); // this is calling the toString() method in the instance of myJavaClass
out.println("</body>"
out.println("</html>"
out.close();
}
/** Handles the HTTP <code>GET</code> method.
* @param request servlet request
* @param response servlet response
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
processRequest(request, response);
}
/** Handles the HTTP <code>POST</code> method.
* @param request servlet request
* @param response servlet response
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
processRequest(request, response);
}
/** Returns a short description of the servlet.
*/
public String getServletInfo() {
return "Short description";
}
}
Example:
import javax.servlet.*;
import javax.servlet.http.*;
public class MyServlet extends HttpServlet {
AJavaClass myJavaClass;
/** Initializes the servlet.
*/
public void init(ServletConfig config) throws ServletException {
super.init(config);
myJavaClass = new AJavaClass();
}
/** Destroys the servlet.
*/
public void destroy() {
}
/** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
* @param request servlet request
* @param response servlet response
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
response.setContentType("text/html"
;java.io.PrintWriter out = response.getWriter();
out.println("<html>"
;out.println("<head>"
;out.println("<title>Servlet</title>"
;out.println("</head>"
;out.println("<body>"
;out.println("this is my class wossname"+myJavaClass.toString()); // this is calling the toString() method in the instance of myJavaClass
out.println("</body>"
;out.println("</html>"
;out.close();
}
/** Handles the HTTP <code>GET</code> method.
* @param request servlet request
* @param response servlet response
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
processRequest(request, response);
}
/** Handles the HTTP <code>POST</code> method.
* @param request servlet request
* @param response servlet response
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
processRequest(request, response);
}
/** Returns a short description of the servlet.

public String getServletInfo() {
return "Short description";
