Lesson #3 Outlines

Choosing Framework ( if you want )
Authenticating Users
Develop First Application

1 - Choosing Framework ( if you want )

Choosing the best application framework almostalways generates a heated debate.

There are pros and cons for each framework, andevery developer has an opinion.

To ensure that your application will run withinthe App Engine server runtime environment, App Engine imposes some constraintsthat enable applications to run “nicely” together and be scalable acrossmultiple distributed runtime instances.

While Google doesn't officially support thelibraries or frameworks that run on App Engine, it does take acommunity-oriented approach to compatibility.

Popular Java libraries and frameworks are listedin the next Table

2 - Authenticating Users

Nearly every web application nowadays requires user authentication.

You’ll build out your authentication framework to let users enter and view timecard entries—naturally, only for themselves.

Authentication with App Engine comes in two flavors. You can choose to plug into Google’s Accounts service (Users service), or you can roll your own with custom classes, tables, and memcache.

User Services :

3 - Develop First Application

1 – Create New web Application Project

2 – Application Directories

3 – Using User Authentication (Servlet Class)

4 – View (Using JSP)

5 - Update web.xml to ( include servlet class , jsp file , and chnage your welcome file )

6 - Run Application As a web application (http://localhost:8888 )

7 - Deploy the ApplicationTo upload your application click on this icon

.... ( note ) .... : if you face any problem after creating your jsp file follow the next steps :

from window menu ---> choose preferences ---> select java ----> select installed JRE

Introduction to Google App Engine ( GAE )

2011-12-15T15:23:00.000+02:00

Lesson #1 Outlines

Introduction
Introduction to Cloud Computing
Difference Between Cloud Computing Types
Introductionto Google App engine

Letus discuss it.

1. Introduction

Application development, as you knowit, is about to change.

Think about your development projectplans for a moment. Do they all seem to have the same line items for the firstphase? Build a server. Install a database. Configure the application server.

You should be able to focus yourenergy on building the application from day one. That’s where Google App Enginecomes into the picture.

App engine is a part of Cloud computing.

2. Introduction to Cloud Computing

Any cloud-computing offering shouldhave certain characteristics Above all, it should be multi tenant.

A key component of a truecloud-computing platform, multitenancy is a type of software architecture whereone instance of the offering is used to serve multiple tenants.

There are three main, acceptedlevels of cloud-computing offerings. They are Infrastructure as a Service (IaaS), Platform as a Service (PaaS),and Software as a Service (SaaS).

3. Difference Between Cloud Computing Types

i - Infrastructure as a Service ( IaaS )

a. lowest level

b. Offers the physical infrastructure (or Virtualized physical infrastructure) to tenants with the ability to pay for what they need in terms of computing power.

c. Instead of purchasing servers, software, and physical location, a tenant of an IaaS offering can pay for these components as needed in a more subscription-based fashion.

d. Amazon.com offer “pay per CPU hour” pricing for Linux and Windows platforms.

ii - Software as a Service ( SaaS )

a. much like IaaS

b. Offers solutions to the customer on a per-usage model.

c. SaaS offerings completely abstract the physical and application layers from the end user or developer.

d. For example, Salesforce.com provides its own customizable user interface and proprietary programming language (Apex) but doesn’t expose to the end user the hardware or software layers that power the application.

e. An important characteristic when it comes to application upgrades and maintenance: everything is centrally updated (available to all customers).

iii- Platform as a Service ( PaaS )

a. Between IaaS and SaaS

b. PaaS offers a bit more than IaaS, without providing an actual end-user product.

c. PaaS components are typically building blocks or solution stacks that you can use to build your own applications.

d. App Engine is a PaaS offering, currently supporting a Java and a Python runtime to build your scalable web applications without the need for complex underlying hardware and software layers.

e. You are restricted by a governor process or application quotas.

f. Application quotas, which Google defines for App Engine applications, define the daily-allotted amount of computing power, space, or bandwidth that any one application is allowed to utilize.

4 - Introduction To Google App Engine

1 - Google App engine Architecture

2 - Why App Engine

Managing everything is very hard ( without GAE)
Hosting (without GAE ) means hidden costs

v Idle capacity

v Software patches & upgrades

v License fees

v Lots of maintenance

v Traffic & utilization forecasting

v Upgrades

GAE Language runtimes ( Python & Java )

3 - Components of an App Engine application

a. SDK & “The Cloud”

b. Hardware

c. Networking

d. Operatingsystem

e. Applicationruntime

f. Java,Python

g. Staticfile serving

h. Services

i. Faulttolerance

j. Loadbalancing

J2ME By Example, How to make simple GUI

2009-12-17T19:08:00.005+02:00

In this lesson we will talk about

1. Form
2. Command – like button in j2se
3. Radiobutton
4. Checkbox
5. Combobox
6. TextField
7. passwordField
8. commandAction Function

now we will discuss each one in detail :-

1. Form

The form is the container that hold our component .

To create the form

Form frmMain = new Form("Title of the form ");

to display it

Display display = Display.getDisplay(this);
display.setCurrent(frmMain);

2. Command

The command is the button that hold the action we will do it
To create button

Command ok = new Command("ok", Command.OK, 1);

First attribute : is the command label
Seconed attribute : command type (ok – cancel – exit …..etc)
Third attribute : is the priority of the button

To add the command to the form

frmMain.addCommand(ok);

to assign action to the button

we refer it to the form but first we must implements the class from CommandListener then override commandAction function to do the action inside it .

we implements the class like this

public class Welcome extends MIDlet implements CommandListener {

the header of the function

public void commandAction(Command c, Displayable d) {}

3. Radiobutton

Allow us to choose one and only one item from two or more items

To create it

Create array hold the items
String[] radio = {"Rock", "paper"};

Declare it

ChoiceGroup radiobutton = new ChoiceGroup("Your choice1:", ChoiceGroup.EXCLUSIVE, radio, null);

Attribute 1 :- radio label
Attribute 2 :- tell the radio to choose only on item .
Attribute 3 :- assign the items using the array
value instead of imageElements.

Add to form

frmMain.append(radiobutton);

4. CheckBox

Allow us to choose multiple items

To create it

Create array hold the items
String[] check = {"Python", "Symbian", "J2ME"};

Declare it

ChoiceGroup checkbox = new ChoiceGroup("Your choice2:", ChoiceGroup.MULTIPLE, check, null);

Attribute 1 :- checkbox label
Attribute 2 :- tell the checkbox to choose multiple item .
Attribute 3 :- assign the items using the array
Null value instead of imageElements.

Add to form

frmMain.append(checkbox);

5. ComboBox

Allow us to choose one item from compact lits

To create it

Create array hold the itemsString[] combo = {"Red", "Green", "blue"};

Declare it

ChoiceGroup combobox = new ChoiceGroup("choose color:", ChoiceGroup.POPUP, combo, null);

Attribute 1 :- combox label
Attribute 2 :- tell the combo to choose one item from compact list .
Attribute 3 :- assign the items using the array
Null value instead of imageElements.

Add to form

frmMain.append(combobox);

6. TextField

An area in which the user input data from the keyboard.the are can also display information

To Declare it

TextField txt = new TextField("Name", "", 15, TextField.ANY);

Add To The Form

• frmMain.append(txt);

7.PasswordField

like TextField put display information in encrypted form

To Declare it

password = new TextField("Pasword", "", 15, TextField.PASSWORD);

Add To The Form

frmMain.append(password);

8. CommandAction Function

the function that hold our action .
after declare it .

public void commandAction(Command c, Displayable d) {}

we check which command make this action like

if(c==ok)
{
//now we wil remove all form item
frmMain.deleteAll();
//now will remove ok command
frmMain.removeCommand(ok);

// now will set title to the form
frmMain.setTitle("your output");

//will display our name and password
frmMain.append("your ouput here \n");
frmMain.append(txt.getString() + "\n");
frmMain.append(password.getString() + "\n");
//then go to the source code to show more and more
}

The run of the code

Conclusion

We have learned how to make gui example in to Java 2 Micro Edition.
This example is very simple example. It can be executed using editors like NetBeans IDE or J2ME Wireless Toolkit(KToolBar). Using API's like JSR 135 etc.. try to create more programs and try them in these tools. I will get back to you with more articles on J2ME.

Unknown Java Traps that most of us fall in, Video Inside

2009-12-14T21:01:00.002+02:00

I watched yesterday awesome tutorial that you deserve to see.
It's about Traps, Pitfalls, and Corner Cases in our lovely language, Java, It deals with 8 issues that most of us fall in it, Not to talk too long, I'll show you the first easy example and let you discover the rest and the reasons at this awesome video introduced by Google.

Problem One:
Here is a Java code and the question is to find the output and the reason of your selection, there are 4 multiple choices to select one from it, let's dance :)

public static void main(String args[]) {
            Set set = new HashSet();
            for (short i = 0; i < 99; i++) {
                set.add(i);
                set.remove(i - 1);
            }
            System.out.println(set.size());
        }

The Options is :

1.
99.
Through an Exception.
None of the above.

You will find the detailed solution with reasons at the first 5 minutes of the video.

Now, I'll let you with the awesome video by Josh Bloch and Bill Pugh.

for any questions, I'll be here and hope to enjoy the tricks.

J2ME By Example, How to enter Mobile World

2009-12-13T20:26:00.001+02:00

We will start in this series simple easy tutorials to start from zero in J2ME track, so stay with us.

1)J2ME Architecture

There are 5 layers in J2ME Architecture.Those are:

MIDP (TopMost Layer): Which contains Java APIs for user network connections, persistence storage, and the user interface. It also has access to CLDC libraries and MIDP libraries.
J2ME API’s(Profiles): Which consists of the minimum set of application programming interfaces for the small computing device
Configurations: Which handles interactions between the profile and the JVM.
JVM
Operating System(Bottom Layer).

2)Simple Example Program

This section shows a simple application. The MIDlet will display the message “ Hi This is My First Program” on the screen. The application consists of the MIDlet subclass called welcome.

To create midlet .

Right-click on project name --> new --> MIDlet

The code .

The run of the project

3) Limitations with J2ME

Some of the limitations of J2ME compared with Core JAVA

Some J2SE applications require classes that are not available in J2ME.
Java applications won’t run in the J2ME environment without requiring modification to the code.
Devices that use the CDC configuration use the full Java Virtual Machine implementation, while devices that use the CLDC configuration use the Kjava Virtual Machine implementation.
MIDlets are controlled by application management software (AMS). So we cant invoke a MIDLET like a J2SE Application.

4)Conclusion

Here with we have an introduction to Java 2 Micro Edition. This example is very simple example. It can be executed using editors like NetBeans IDE or J2ME Wireless Toolkit(KToolBar). Using API's like JSR 135 etc.. try to create more programs and try them in these tools. I will get back to you with more articles on J2ME.

1- Add MySQL library to NetBeans IDE.

Right-click on project name choose properties
Click on library

Add library

Choose MySQL
Add the library

2- Add Hibernate library to NetBeans IDE.

3- Use MySQL Server to make small table

Download mysql from ( http://dev.mysql.com/downloads/mysql/5.1.html#win32 )

Install these two file the very important step

1- setting the password ( if you have loder version and removed it you will see current root password , if not you will not see it )(hint : we use password -- 12345)

2- Ensure that mysql server installed correctly (otherwise you must reinstall mysql)

4- Make the first Hibernate application and connect it to MySQL Server.

1. Make java application

2. Add mysql liberary and hibernate library

3. Build our database

Table name student (use default schema test)

Name	Age
Ahmed	21
Islam	21
Ali	20

4- build hibernate configuration file ( this file define you database engine ,your password , and driver that’s essentially to connect to mysql or other database engines) . configuration file is an xml file .it is name ( hibernate.cfg.xml ) . place in default package .

right-click on default -package choose other

Then click finish

Now we will explain hibernate configuration file

5 – build java bean class . this class have fields that we name it in our database

Every table in our database have one bean implements database fields place it in default package .

6- now build xml file have name like the java bean class name (in our project Main ) this file named with hibernate mapping file . we use this file to assign each attribute in our bean class to each field in our database.(hint :each table in our database has java bean class and mapping file to connect each).

- Now to begin our first project we must do the main class we will name it (insert )

How to customize NetBeans IDE, Configure Used-Memory and Look And Feel and more in just 2 Minutes

2009-12-06T22:29:00.006+02:00

NetBeans Performance sucks and want to give it more resources (Memory...) to perform better?!
Want to Change the Netbeans IDE Look and Feel in just 2 minutes?!
Did you ever un-installed the JDK Accidentally and want to reinstall only the JDK without reinstalling NetBeans IDE?!

Well, We will do all of that and more by editing the start-up parameters with two easy methods, hope to enjoy them.

First Method, Editing the netbeans.conf file:

Finding the Configuration File : At every PC with NetBeans Installed, there are two versions of the netbeans.conf file, a global and a local one.

We can use :

The Global : If we want to change the settings for all users using a shared NetBeans installation, You find it in the NetBeans installation directory:
The Local : If we want to make individual changes that will apply only to a specific user, You find it in the user's userdir .
1st PS : If you cant find the userdir, you will find more about it here.
2nd PS:The local file does not exist by default! If you don't see a ${userdir}/etc directory you have to create the file yourself. The easiest way to do that is to copy the global netbeans.conf file from the NetBeans installation folder to the local ${userdir}/etc folder, and then make the desired changes.

Edit the netbeans.conf file : We will use the following elements at the netbeans.conf file

netbeans_default_options : We may use this for changing the memory configuration, changing Look and Feel, etc.

For Example:
to change the Look and Feel edit the next parameter

--laf LookAndFeelClassName
(e.g.) --laf javax.swing.plaf.metal.MetalLookAndFeel

to change the font size edit the next parameter

--fontsize size
(e.g.) --fontsize 14

to change the initial heap size edit the next parameter

-J-Xms sizeInMegaBytes
(e.g.) -J-Xms128m

to change the maximum heap size edit the next parameter

-J-Xmx sizeInMegaBytes
(e.g.) -J-Xmx384m

netbeans_jdkhome : We may use this for changing the location of the JDK which will be used to run NetBeans.

For Example:
# Default location of JDK, can be overridden by using --jdkhome dir
netbeans_jdkhome="C:\Program Files\Java\jdk1.6.0_13"

Note that :

The “#” character means that the following line is a comment.
IF the global and the local configurations made a conflict the :

The setting in the local file have the priority to be executed over the global one.
If you running the IDE from command line, the command line parameters have the priority to be executed over both the local and the global configurations.

Second Method, NetBeans Startup Settings Plugin:

You can use this cool tool created by Claudio Miranda to edit all of this configurations easily.

Features :

Backup and restore original settings (etc/netbeans.conf).
Able to configure and store different JDK and NetBeans user directory.
Store settings (jdk and userdir) under JDK Preference API.
Support to on-line updates through update center.
LGPL license.
If specified userdir doesn't exist, a new one will be created.
Remember netbeans user and JDK directories, across different NetBeans installations.

Requirements :

JDK 5 or higher.
NetBeans 6.x.
A writable $HOME/.java/.userPrefs directory.

Setup :

You may do an anonymous checkout, you must have subversion client installed, by invoking :
svn co --username anonymous --password anon http://svn.javaforge.com/svn/netbeans-modules/trunk/nb-settings nb-settings
Or you may download this nbm file, however this is not recommended.

After installing the plugin you can reach to it by going to Tools > Options > Miscellaneous, and here is the screen shot of the plugin.

Please feel free to contact us for more information about the post or about installing the NetBeans IDE modules.

Hope you enjoyed the post of this day and learned a new stuff. Your comment always inspiring us and the main motivator for doing our best, So please leave your comment whatever it was, It always help.

How to secure Java Applications by using VBScript to get a Unique Computer Serial Number

2009-12-05T04:34:00.025+02:00

Did you tried many times to get a unique computer ID to use it in securing your java application?!

Do you want to know the easy way to get that ID in just 5 minutes?!!

Yes you can, We will learn how to get basic hardware serial numbers at windows platform and you will find the complete code at the end of the tutorial.

before we start any one may ask why I even want to get this number?
Well, consider that scenario :

you have developed some application and want to distribute it for some of money. We here have a point, how we will be sure that if I sold it for someone, he will not redistribute it, So we will use that Unique ID to give him a copy that will run only on his PC.

Make sense !, So lets dance.
We will use the VBScript codes on the fly to get the system info like CPU information or Motherboard information Like this:

Here is the Java source code to get the Unique ID divided on to two parts.
First Part of Java Code:

We here open temp File to put the script on it, We use temp folder on C:\ Drive to execute the script and then delete it.

Second Part of Java Code:

We here execute the ".vbs" file after writing the script on it and then we retrieve the results and close the file.

Take on your mind that:

When you put your VBScript Code as String you must convert all special characters(e.g the " will be \" ).

For Example:
If the VBScript is

Set objReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv")

The String will be

String vbs="Set objReg = GetObject(\"winmgmts:{impersonationLevel=impersonate}!\\\\\" & strComputer & \"\\root\\default:StdRegProv\")";

You can customize the VBScript code as you want. For more VBScript Code use TechNet Script Center Gallery.

Here is the full source code with sample VBScript:

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class VBSUtil {

    private VBSUtil() {
    }
    static String result = "";

    private static String getMotherboardSN() {
        try {
            File f = new File("C:\\");
            File file = File.createTempFile("realhowto", ".vbs", f);
            file.deleteOnExit();
            FileWriter fw = new java.io.FileWriter(file);
            String vbs = "On Error Resume Next\n" + "strComputer = \".\"\n" + "Set objWMIService = GetObject(\"winmgmts:\\\\\" & strComputer &  \"\\root\\cimv2\")\n" + "Set colItems = objWMIService.ExecQuery(\"Select * from  Win32_Processor\")\n" + "For Each objItem in colItems\n" + " Wscript.Echo \"Processor Id: \" & objItem.ProcessorId\n" + "Next\n" + "strComputer = \".\"\n" + "Set objWMIService = GetObject(\"winmgmts:\" _\n" + "  & \"{impersonationLevel=impersonate}!\\\\\" & strComputer &  \"\\root\\cimv2\")\n" + "Set colBIOS = objWMIService.ExecQuery _\n" + "(\"Select * from Win32_BIOS\")\n" + "For each objBIOS in colBIOS\n" + "  Wscript.Echo \"Release Date: \" & objBIOS.ReleaseDate\n" + "next";
            fw.write(vbs);
            fw.close();
            Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
