Important

Aspire 4.0 runs on Java SE 11.

Install the Java Components


Download and install Java

This is the version that is appropriate for the system that will run Aspire:http://java.com/en/download/manual.jsp

  1. If you have a 64-bit machine, install the 64-bit version of Java. That will allow you to create large-memory instances of Aspire.

The Aspire framework itself does not use up that much memory (100mb or so). However, some applications may store big hash tables to improve performance, so it's best to have the 64-bit JVM  just in case you need it someday.

Test your access to the "java" command from your console

  1. Open 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 and press Enter: java -version.

    Success is indicated when version information is returned.

> java -version
   java version "11.0.2" 2019-01-15 LTS
   Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
   Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)

Add the "JAVA_HOME" environment variable

This is needed by the Maven command-line tool. In Windows:

  1. Open the control panel.
  2. Go to SystemAdvanced System Settings > Advanced > Environment Variables.

  3. Under System variables, click New.

  4. Enter "JAVA_HOME" as the Variable name.

  5. Locate the directory within your Program files where java was installed.

  6. Enter this directory name as the Variable value.

For Linux systems:

  1. In Linux, open a terminal.
  2. Type "echo $JAVA_HOME" and press Enter. If nothing is displayed, we can set it at startup by doing step 3.
  3. Type "echo JAVA_HOME=/your/java/directory >> ~/.profile"
  4. Logout and login again, repeating steps 1 and 2 to check if JAVA_HOME was successfully set.
