Cara Menambahkan Syntax Highlighter Script Box dan Scroll di Blog

assalamualaikum :D
halo sobat semua, kali ini saya akan berbagi tentang cara menambahkan secara Syntax Highlighter, Script Box dan Scroll secara manual selain menggunakan pastebin.com. langsung aja ngga perlu basa basi.

Syntax Highlighter
1. Login ke blog
2. Masuk ke menu Template
3. Edit Tempalate. kemudian cari script
kemudian tambahkan code ini dibawah
4. Sesudah itu kemudian simpan

5. Saat akan melakukan posting, buat posting dengan mode html. kemudian masukkan kode di bawah ini

6. Selesai

// SyntaxHighlighter makes your code snippets beautiful without tiring your servers.
// http://alexgorbatchev.com
var setArray = function(elems) {
    this.length = 0;
    push.apply(this, elems);
    return this;
}

Script Box dan Scroll

Saat akan membuat postingan, pilih mode html kemudian tambahkan kode di bawah ini


selesai

// SyntaxHighlighter makes your code snippets beautiful without tiring your servers. // http://alexgorbatchev.com var setArray = function(elems) { this.length = 0; push.apply(this, elems); return this; }

semua terlihat lebih rapi kita gabungkan keduanya seperti ini

// SyntaxHighlighter makes your code snippets beautiful without tiring your servers.
// http://alexgorbatchev.com
var setArray = function(elems) {
    this.length = 0;
    push.apply(this, elems);
    return this;
}

terimakasih. semoga bermanfaat bagi kawan-kawan semua.

Membuat Servlet Context dan Listener Database di Java Servlet

assalamualaikum kawan-kawan :)

postingan ini adalah lanjutan yang sebelumnya tentang Servlet Filter, kali ini saya akan sharing tentang program Java Servlet Context dan Listener Database. Langsung aja kita buat programnya

pertama kita buat index.html

    
        
        
    
    
        servlet context dan Listener
    

kemudian kita buat class bernama DBConnectionManager.java
source codenya sebagai berikut :

import java.sql.Connection;
/**
 *
 * @author Ilyas A. Jaelani
 */
public class DBConnectionManager {
    private String dbURL;
    private String user;
    private String password;
    private Connection con;
    
    public DBConnectionManager(String url, String u, String p) {
        this.dbURL = url;
        this.user = u;
        this.password = p;
//create db connection now
    }
    public Connection getConnection() {
        return this.con;
    }

    public void closeConnection() {
//close DB connection here
    }   
}

buat file servlet MyServlet.java
source codenya sebagai berikut :

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

/**
 *
 * @author Ilyas A. Jaelani
 */
public class MyServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * Processes requests for both HTTP
     * GET and
     * POST methods.
     *
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
     */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            /* TODO output your page here. You may use following sample code. */
            out.println("");
            out.println("");
            out.println("");
            out.println("");            
            out.println("");
            out.println("");
            out.println("

Servlet MyServlet at " + request.getContextPath() + "
");
            out.println("");
            out.println("");
        } finally {            
            out.close();
        }
    }

    // 
    /**
     * Handles the HTTP
     * GET method.
     *
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
     */
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
//        processRequest(request, response);
        ServletContext ctx = request.getServletContext();
        ctx.setAttribute("User", "Ilyas");
        String user = (String) ctx.getAttribute("User");
        ctx.removeAttribute("User");

        HttpSession session = request.getSession();
        session.invalidate();

        PrintWriter out = response.getWriter();
        out.write("Hi " + user);

    }

    /**
     * Handles the HTTP
     * POST method.
     *
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
     */
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        processRequest(request, response);
    }

    /**
     * Returns a short description of the servlet.
     *
     * @return a String containing servlet description
     */
    @Override
    public String getServletInfo() {
        return "Short description";
    }// 
}

Tambahkan  file  listener  baru  dengan  nama AppContextListener.java. Ikuti  langkah sebagai berikut :

source codenya sebagai berikut :

import javax.servlet.ServletContext;

        String url = ctx.getInitParameter("DBURL");
        String u = ctx.getInitParameter("DBUSER");
        String p = ctx.getInitParameter("DBPWD");

        //create database connection from init parameters and set it to context
        DBConnectionManager dbManager = new DBConnectionManager(url, u, p);
        ctx.setAttribute("DBManager", dbManager);
        System.out.println("Database connection initialized for Application.");
        
//        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override

        ServletContext ctx = sce.getServletContext();
        DBConnectionManager dbManager = (DBConnectionManager) ctx.getAttribute("DBManager");
        dbManager.closeConnection();
        System.out.println("Database connection closed for Application.");
    
//        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
}

Tambahkan  file  listener  baru  dengan  nama AppContextAttributeListener.java.

//        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public void attributeRemoved(ServletContextAttributeEvent event) {
                System.out.println("ServletContext attribute replaced::{" + event.getName() + "," + event.getValue() + "}");

//        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
}

Tambahkan  file  listener  baru  dengan  nama MySessionListener.java.

source codenya sebagai berikut :

    }
}

Tambahkan  file  listener  baru  dengan  nama MyServletRequestListener.java.

source codenya sebagai berikut :

import javax.servlet.ServletRequestEvent;
import javax.servlet.ServletRequest;

/*

Membuat Servlet Context dan Listener di Java Servlet

assalamualaikum kawan-kawan :)

postingan ini adalah lanjutan yang sebelumnya tentang Servlet Filter, kali ini saya akan sharing tentang program Java Servlet Context dan Listener. Langsung aja kita buat programnya

pertama kita buat index.html

    
        
        
    
    
        view servlet context
    

kemudian kita tambahkan script dibawah ini :

lalu kita buat ServletContextClass.java

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

     */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            /* TODO output your page here*/
            out.println("");
            out.println("");
            out.println("");
            out.println("");
            out.println("");
            out.println("

        } finally {
            out.close();
        }
    }

    // 
    /**

     */
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        //processRequest(request, response);
        response.setContentType("text/html; charset=UTF-8");
        PrintWriter out = response.getWriter();

        ServletContext ctx = getServletContext();

        ctx.setAttribute("name", "Eresha Wikrama");
        out.print(ctx.getAttribute("name"));

        Enumeration temp = ctx.getAttributeNames();
        while (temp.hasMoreElements()) {
            String attrName = (String) temp.nextElement();
            out.print("Attribut " + attrName + " , nilainya = " + ctx.getAttribute(attrName));
        }

        out.print("

getServletContextName() : " + ctx.getServletContextName());

        out.print("
" + ctx.getInitParameter("bhs1"));
        Enumeration temp2 = ctx.getInitParameterNames();
        while (temp2.hasMoreElements()) {
            String paramName = (String) temp2.nextElement();
            out.print("
Attribut " + paramName + " , nilainya = " + ctx.getInitParameter(paramName));
        }

        out.print("
getServerInfo() : " + ctx.getServerInfo());
        out.print("
getRealPath() : " + ctx.getRealPath(""));
        ctx.log("Hello world");
        ctx.setAttribute("name", "Eresha Wikrama Bogor, Teknik Informatika");
        ctx.setAttribute("name", null);

        request.setAttribute("word", "never say give up in this world");
        request.setAttribute("word", "do your best and let God do the rest");
        request.setAttribute("word", null);

        HttpSession session = request.getSession();
        session.setAttribute("userSession", "EreshaWikramaSession");
        session.setAttribute("userSession", "Mari belajar JAVA");
        session.setAttribute("userSession", null);
    }

    /** 
     * Handles the HTTP POST method.
     * @param request servlet request

     */
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        //processRequest(request, response);
    }

    /** 
     * Returns a short description of the servlet.
     * @return a String containing servlet description
     */
    @Override
    public String getServletInfo() {
        return "Short description";
    }// 
}

Kemudian buat sebuah 6 buah class untuk mengimplementasikan setiap interface listener
di atas. Sebenarnya buat 1 class juga bisa untuk mengimplementasikan keenam interface
tersebut. Namun ada baiknya dipisah saja per interface, supaya lebih mudah dicerna.

ServletContextListener
Tambahkan  file  listener  baru  dengan  nama ServletContextListenerClass.java. Ikuti  langkah
berikut ini:

jikalau tidak ada, pilih other terlebih dahulu

 

source codenya sebagai berikut :

import javax.servlet.ServletContext;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

/**
 * Web application lifecycle listener.
 * @author ROOT
 */
public class HttpSessionListenerClass implements HttpSessionListener {

    @Override
    public void sessionCreated(HttpSessionEvent se) {
        ServletContext ctx = se.getSession().getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "session " + se.getSession().getId() + " sudah dibuat");
    }
    }

    @Override
    public void sessionDestroyed(HttpSessionEvent se) {
        ServletContext ctx = se.getSession().getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "session " + se.getSession().getId() + " sudah dihancurkan");
    }
    }
}

ServletContextAttributeListener
Selanjutnya buat file ServerListener dengan nama ServletContextAttributeListenerClass.java,
pada bagian Interfaces to Implement, pilih Context Attribute Listener.

source codenya sebagai berikut :

import javax.servlet.ServletContext;
import javax.servlet.ServletContextAttributeEvent;
import javax.servlet.ServletContextAttributeListener;

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

/**

       ServletContext ctx = event.getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "attribute " + event.getName() + " dengan nilai : " + event.getValue()
                + " sudah ditambahkan");
    }
    }

    @Override
    public void attributeRemoved(ServletContextAttributeEvent event) {
       ServletContext ctx = event.getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "attribute " + event.getName() + " dengan nilai : " + event.getValue()
                + " sudah dihapus");
    }
    }

    @Override
    public void attributeReplaced(ServletContextAttributeEvent event) {
        ServletContext ctx = event.getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "attribute " + event.getName() + " dengan nilai : " + event.getValue()
                + " sudah diubah");
    }
    }
}

ServletRequestListener
Selanjutnya buat file ServerListener dengan nama ServletRequestListenerClass.java, pada kolom
Interfaces to Implement pilih Request Listener:

source codenya sebagai berikut :

public class ServletRequestListenerClass implements ServletRequestListener {

    @Override
    public void requestDestroyed(ServletRequestEvent sre) {
        ServletContext ctx = sre.getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                 + "request " + sre.getServletRequest() + " sudah dihancurkan");
    }
    }

    @Override
    public void requestInitialized(ServletRequestEvent sre) {
       ServletContext ctx = sre.getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                 + "request " + sre.getServletRequest() + " sudah diinisialisasi");
    }
    }
}

ServletRequestAttributeListener
Selanjutnya buat file ServerListener dengan nama ServletRequestAttributeListenerClass.java,
pada bagian Interfaces to Implement, pilih Context Attribute Listener.

source codenya sebagai berikut :

import javax.servlet.ServletRequestAttributeEvent;

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

/**

//        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public void attributeReplaced(ServletRequestAttributeEvent event) {

//        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
}

HttpSessionAttributeListener
Selanjutnya buat file ServerListener dengan nama HttpSessionAttributeListenerClass.java, pada
kolom Interfaces to Implement pilih HTTP Session Attribute Listener:

source codenya sebagai berikut :

import javax.servlet.ServletContext;
import javax.servlet.http.HttpSessionAttributeListener;
import javax.servlet.http.HttpSessionBindingEvent;

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

/**

public class HttpSessionAttributeListenerClass implements HttpSessionAttributeListener {

    @Override
    public void attributeAdded(HttpSessionBindingEvent event) {
        ServletContext ctx = event.getSession().getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "session attribute " + event.getName() + " dengan nilai : " + event.getValue()
                + " sudah ditambahkan");
    }
    }

    @Override
    public void attributeRemoved(HttpSessionBindingEvent event) {
        ServletContext ctx = event.getSession().getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "session attribute " + event.getName() + " dengan nilai : " + event.getValue()
                + " sudah dihapus");

    }

    @Override

       ServletContext ctx = event.getSession().getServletContext();
    if (ctx != null) {
        ctx.log("Context " + ctx.getServletContextName() + ", "
                + "session attribute " + event.getName() + " dengan nilai : " + event.getValue()
                + " sudah diubah");
    }
    }
}

HttpSessionListener
Selanjutnya buat file ServerListener dengan nama HttpSessionListenerClass.java, pada
kolom Interfaces to Implement pilih HTTP Session Attribute Listener:

source codenya sebagai berikut :

import javax.servlet.ServletContext;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;

                + "session " + se.getSession().getId() + " sudah dihancurkan");
    }
    }
}

di file web.xml yang ada di folder WEB-INF kita tambahkan code berikut
