Compatibility Issues

CA XCOM Gateway requires the environment variable JAVA_HOME to be set to the JDK (Java Development Kit) directory. If JAVA_HOME is set to the JRE (Java Runtime Environment) directory or to a private third-party JVM, JBOSS will not start and EEM will not install as part of CA XCOM Gateway.

To find out which directory JAVA_HOME is set to

1. Navigate to the bin directory immediately beneath the directory set in JAVA_HOME.
2. Look for a member called javac.exe.

   This file exists only in the JDK bin directory. If the file is not there then your JAVA_HOME environment variable is set to the JRE directory.

If the JAVA_HOME variable is set to a JRE directory or a private JVM and it cannot be changed, then use the following procedure:

To install CA XCOM Gateway

1. Open a Windows command line window.
2. Navigate to where the CA XCOM Gateway install.exe file is located.
3. To set the local JAVA_HOME variable to the Java JDK location, execute the following command:

   SET JAVA_HOME=<JDK location>
   

   Example:

   SET JAVA_HOME=C:\Program Files\Java\jdk1.6.0_11
   

4. To execute the installer, type install and press Enter.
