Follow the instructions below to install the required applications and ESB on Windows.

Install the Required Applications

  1. Be sure your system meets the Installation Prerequisites, and then install the following applications:

    1. Install Java Development Kit (JDK)

    2. Install Apache Ant

    3. Install Apache Maven

    4. Install Apache ActiveMQ

Install the ESB

  1. If you have not done so already, download the latest version of the ESB as described in Obtaining the Product.

  2. Extract the archive file to a dedicated directory for the ESB, which will hereafter be referred to as <PRODUCT_HOME>.

Set Up JAVA_HOME

You must set your JAVA_HOME environment variable to point to the directory where the Java Development Kit (JDK) is installed on the computer. Typically, the JDK is installed in a directory under C:\Program Files\Java, such as C:\Program Files\Java\jdk1.6.0_27. If you have multiple versions installed, choose the latest one, which you can find by sorting by date.

Environment variables are global system variables accessible by all the processes running under the operating system. You can define an environment variable as a system variable, which applies to all users, or as a user variable, which applies only to the user who is currently logged in.

You set up JAVA_HOME using the System Properties, as described below. Alternatively, if you just want to set JAVA_HOME temporarily for the current command prompt window, set it at the command prompt.

Setting Up JAVA_HOME Using the System Properties

1. Right-click the "My Computer" icon on the desktop and choose Properties.

2. In the System Properties window, click the Advanced tab, and then click the Environment Variables button.

3. Click the New button under "System variables" (for all users) or under "User variables" (just for the user who is currently logged in).

4. Enter the following information:

  • In the "Variable name" field, enter: JAVA_HOME
  • In the "Variable value" field, enter the installation path of the Java Development Kit, such as: c:\Program Files\Java jdk1.6.0_27

5. Click OK.

The JAVA_HOME variable is now set and will apply to any subsequent command prompt windows you open. If you have existing command prompt windows running, you must close and reopen them for the JAVA_HOME variable to take effect, or manually set the JAVA_HOME variable in those command prompt windows as described in the next section. To verify that the JAVA_HOME variable is set correctly, open a command window (from the Start menu, click Run, and then type CMD and click Enter) and execute the following command:

set JAVA_HOME

The system returns the JDK installation path. You are now ready to run the product.

Setting JAVA_HOME Temporarily Using the Windows Command Prompt (CMD)

You can temporarily set the JAVA_HOME environment variable within a Windows command prompt window (CMD). This is useful when you have an existing command prompt window running and you do not want to restart it.

1. In the command prompt window, enter the following command where <JDK_INSTALLATION_PATH> is the JDK installation directory and press Enter:

set JAVA_HOME=<JDK_INSTALLATION_PATH>

For example:

set JAVA_HOME=c:\Program Files\java\jdk1.6.0_27

The JAVA_HOME variable is now set for the current CMD session only.

2. To verify that the JAVA_HOME variable is set correctly, execute the following command:

set JAVA_HOME

The system returns the JDK installation path. You are now ready to run the product.
