Environment Setup

• Java Environment Setup is a process that includes very simple steps but its very important to configure this in a good way.

• It is very important before we proceed further that we set up the java environment correctly.

• This section guides you on how to download and set up Java on your machine.

• Please follow the following steps to set up the environment.

• Java SE is freely available from the link Download Java.

• So you download a version based on your operating system.

• Follow the instructions to download java and run the .exe to install Java on your machine.

• Once you installed Java on your machine, you would need to set environment variables to point to correct installation directories.

Setting up the path for windows 2000/XP:-

• Assuming you have installed Java in c:\Program Files\java\jdk directory

• Right-click on 'My Computer' and select 'Properties'.

• Click on the 'Environment variables' button under the 'Advanced' tab.

• Now alter the 'Path' variable so that it also contains the path to the Java executable. Example, if the path is currently set to 'C:\WINDOWS\SYSTEM32', then change your path to read 'C:\WINDOWS\SYSTEM32;c:\Program Files\java\jdk\bin'.

Setting up the path for windows 95/98/ME:-

• Assuming you have installed Java in c:\Program Files\java\jdk directory:

• Edit the 'C:\autoexec.bat' file and add the following line at the end: 'SET PATH=%PATH%;C:\Program Files\java\jdk\bin'

Setting up the path for Linux, UNIX, Solaris, FreeBSD:-

• Environment variable PATH should be set to point to where the java binaries have been installed. Refer to your shell documentation if you have trouble doing this.

• Example, if you use bash as your shell, then you would add the following line to the end of your '.bashrc: export PATH=/path/to/java:$PATH'
