Configuring Java system variables and the Windows path
Now that we have installed JDK/JRE, we have to set up JAVA system variables
and set Windows paths both for the ADempiere server and the client computer,
as ADempiere runs on a Java platform.
We need to set these variables in the System Properties window. You can access
this window through Start | Control Panel | System (or Start | Settings | Control
Panel | System in the case of the Windows classic menu). Select the Advanced
system settings tab, and click on the Environment Variables button.
The following table shows the value of a Java system variable and a Windows
path for the ADempiere server installation to be set up in the Environment
Variables window:
No Variable          Value
1    JAVA_HOME       C:\Java\jdk1.5.0_17
2    Path            %JAVA_HOME%\bin;%JAVA_HOME%\jre\bin\client
For the ADempiere client installation, you may set the following Java system variable
and Windows path in the Environment Variables window:
No Variable          Value
1    JAVA_HOME       C:\Java\jre1.5.0_17
2    Path            %JAVA_HOME%\bin;%JAVA_HOME%\bin\client
