Installing XAMPP on Windows

1. Download the software from: http://www.apachefriends.org/en/xampp-windows.html#641

   Select the Installer option under the Basic Package. You may be taken to a page that presents you with a bunch of different download locations. Just click one of the download buttons, and then save the file to your desktop. Once downloaded, the installer works like most Windows installers.
   In Internet Explorer, you may get a warning about downloading the file. Click the yellow information bar that appears above the Web page in IE, and choose Download File…
2. Double-click the .exe file you downloaded.
   A window opens, asking you to select the language you’d like to use.
   If a warning dialog appears click the "Allow" option to install XAMPP.
3. Choose a language from the menu, and then click OK.
   A Setup Wizard window appears, ready to step you through the setup process.
   In Vista you may see a message warning you that XAMPP may not work when installed in the C:\Program Files directory. The default installation is in C:\XAMPP so you don’t have to worry about this problem.
4. Click the Next button.
   

   The installer suggests putting the application on your main drive at C:\XAMPP. You can pretty much install it anywhere, but with the Vista operating system you may encounter problems if you install it in C:\Program Files.
5. Click the Next button once again.
   The XAMPP Options window appears (see below). In most cases, it’s fine to leave all the window’s checkboxes just as you see; see the note below for details.
   
   
   

   

   
   

   If you plan on doing a lot of development, day in and day out, you might want to turn on the “Install Apache as service” and “Install MySQL as service” checkboxes. A service starts up every time you turn on your computer, so Apache, PHP, and MySQL are always running. However, if you won’t be building database sites frequently, or you don’t have a lot of RAM in your computer, don’t turn on these boxes (you’ll just have to manually start the servers when you wish to build dynamic pages, using the XAMPP control panel described on the next page). 

   
   

   6. Click Install.

   The installer places all the files onto your system. This process takes a while, since a lot of programs and files are being installed. 

   
   

   7. Finally, click the Finish button.

   A window appears “congratulating” you (way to double-click the installer program!), and asking whether you wish to start the XAMPP Control panel. 

   
   

   8. Click Yes, to open the XAMPP Control Panel (see screenshot below).

   The XAMPP Control Panel lets you start and stop the Apache Web server and MySQL database server.

   
   

   

   
   

   10. If the buttons to the right of Apache and MySQL say Start, click them to start the Web server and the MySQL database server.

   You probably get a Windows security alert about both MySQL and Apache: Click the Unblock button in both cases. This action allows the two servers to run, and tells the Windows firewall protection service that everything is OK.If Apache and MySQL are already running, these buttons say Stop. (Clicking them turns off the Web server and MySQL.) Whenever you start Apache, PHP automatically starts as well. At this point, you should have a complete testing server running on your machine. You just need to make sure it’s working. 

   
   

   11. To do so, launch a Web browser, and, in the Location bar, type http://localhost/.

   You encounter a page that lists a bunch of languages; click the language you prefer, and you’re taken to a kind of Web-based control panel for XAMPP (see screenshot below).

   
   

   

   
   

   Once installed, you can view your XAMPP home page from http://localhost/xampp/. From the left-hand list of links, you can access helpful programs and information, such as phpMyAdmin (for working with the MySQL database) and phpinfo() for finding out more about the server setup.

   
   

   Once you’ve installed XAMPP, you’ll see a shortcut called XAMPP Control Panel on your desktop. Double-click this icon to control the servers you’ve just installed—you can turn the servers off and on, as well as turn them into services (which launch each time you start up your computer).

   To uninstall XAMPP, just go to the location where you installed XAMPP (like C:\XAMPP\) and run the program named Uninstall.exe. This action, however, deletes any databases you created, and destroys any Web pages that you placed on the server. To prevent this process, just follow these steps: First, use phpMyAdmin to export any database you wish to save (you can find instructions at http://php.about.com/od/learnmysql/ss/mysql_backup_3.htm ), and then make a copy of your Web pages which are located in the C:\XAMPP\htdocs folder.

   
   

How to change WAMP server port

TO CHANGE THE WAMP SERVER PORT NUMBER:

1. Stop the WAMP server, if it is running already.
2. Open the file [WAMPP Installation Folder]/apache/conf/httpd.conf.
3. Now search for the string Port 80 (I’m assuming that your WAMP was using the port 80. Otherwise, just search for the string “Listen”). This is the port number which WAMP uses. Change this 80 to any other number which you prefer.
4. Then search for the string “ServerName” and update the port number there also.
5. Now save and re-start WAMP server and you are done.

How to change XAMPP server port

To change the XAMPP server port number:

1. Stop the XAMPP server, if it is running already.
2. Open the file [XAMPP Installation Folder]/apache/conf/httpd.conf.
3. Now search for the string Listen 80 (I’m assuming that your XAMPP was using the port 80. Otherwise, just search for the string “Listen”). This is the port number which XAMPP uses. Change this 80 to any other number which you prefer.
4. Then search for the string “ServerName” and update the port number there also.
5. Now save and re-start XAMPP server and you are done.

Why do we need to change the port number? Because, these days, it is very common that a web developer needs to have multiple web servers running, all at the same time. For example, an XAMPP server can be used to run the local WordPress blog, while a JBoss server also needs to be up for testing a java web applications. In such scenarios, if two or more servers are trying to use the same port number, then the late comer will fail to get the port. So, it becomes necessary to change any one server’s port number to avoid the conflict.

Java Mail

For Windows users only Pre-Requisites: jdk1.6.0_11 ( works with previous versions of JDK)

 Installed location:

• jdk1.6.0_11 ->   C:\Program Files\Java\jdk1.6.0_11\
• mail.jar ->   D:\apache-tomcat-6.0.18\lib\mail-1.3.3.jar

Environment Variables:

Enter Variable name and Variable value which is mentioned below.

Variable name:	JAVA_HOME
Variable value:	C:\Program Files\Java\jdk1.6.0_11

Variable name:	PATH
Variable value:	C:\Program Files\Java\jdk1.6.0_11\bin

Variable name:	CLASSPATH
Variable value:	.;D:\apache-tomcat-6.0.18\lib\mail-1.3.3.jar

Note

There first character in classpath should be a period (.) 

Download Links:

1. Click here to download mail-1.3.3.jar
2. javamail.default.address.map
3. javamail.address.map
4. javamail.providers
5. javamail.default.providers

Steps to run the below example program

Before running the below example program make sure that mail.jar is in the classpath. Using the below program you can send mail only from Gmail, but the receiving mail ID can be anything. If you want to send mail from some other mail providers, then change theSMTP_HOST_NAME and SMTP_PORT accordingly to mail providers. Change theemailMsgTxt, emailSubjectTxt, emailFromAddress according to your need.

protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(" yourMaidID", "yourPassword");
}

Replace "yourMaidID" with from address (i.e. the mail ID from where email should go) and replace " yourPassword" with the password of the corresponding mail ID.

While running the below program you may encounter some errors in console which is given below. This is just a warning. By default our program will look for javamail.providers, javamail.address.map, javamail.default.address.map, javamail.default.providers in "C:\Program Files\Java\jre6\lib\" folder. So to avoid this warnings you just create four files inside "C:\Program Files\Java\jre6\lib\" with the below names. Make sure that the extension of the file is not in .txt format.
(little workaround to make sure the extension is not of type .txt - Click My Computer ->Tools -> Folder Options -> View -> Advanced settings ->
Uncheck the check box "Hide extensions for known file types". Now navigate to "C:\Program Files\Java\jre6\lib\" and check for the file extensions.)

Warnings

DEBUG: java.io.FileNotFoundException: C:\Program Files\Java\jre6\lib\javamail.providers (The system cannot find the file specified)
DEBUG: java.io.FileNotFoundException: C:\Program Files\Java\jre6\lib\javamail.address.map (The system cannot find the file specified)
