Installing Java

Step-by-step guide

The version of Java you should use depends on the Aspire version you are targeting to:

• Aspire 3 and up requires to run at Java 1.7 and above.

1. Download and install the latest version of the Java JDK appropriate for the system that will run Aspire:http://java.com/en/download/manual.jsp

   1. If you have a 64 bit machine, we recommend installing the 64 bit version of Java. That will allow you to create large-memory instances of Aspire.
      1. The Aspire framework itself does not use up that much memory (100mb or so). But some applications may store big hash tables to improve performance, so it's best to have the 64 bit JVM (Java Virtual Machine), just in case you need it someday.
2. Test that you can access the "java" command from your console.
   1. Open up a new DOS command-shell (go to the start menu, and enter "cmd" where it says "Run" or "Search for Programs", and then execute the cmd.exe program).

   2. At the prompt, enter the following, then press the Enter key: java -version

   3. Success is indicated when version information is returned.

      
3. Add the "JAVA_HOME" environment variable.
   1. This is needed by the Maven command-line tool described below.
      1. Open up your control panel
      2. Go to the "System" control panel (may be inside the 'System and Security' category)
      3. Open up the "Advanced System Settings"
      4. Go to the "Advanced" tab (may already be selected)
      5. Click on "Environment Variables"
      6. Click on "New..."
      7. Enter "JAVA_HOME" as the "Variable name:"
      8. Locate the directory within your Program files where java was installed. Enter this directory name as the "Variable value:"

> java -version
  java version "1.7.0_79"
  Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
  Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
