1.2. Java Runtime

Fuse runtime platforms need Java 6, JRE 1.6.0_18 or later.

To develop applications for Fuse runtime platforms, you need Java 6, JDK 1.6.0_18 or later.

Non-Oracle Java distributions

Fuse products are only guaranteed to run with Java runtimes distributed by, or OEMed from, Red Hat (OpenJDK), Oracle and IBM.

Red Hat Linux

On Red Hat-derived Linux systems, gcj is the default Java distribution. In these cases, you must download and install an Oracle Java runtime and set the JAVA_HOME environment variable. You can also integrate the Oracle Java runtime into the alternatives(1) system. See the alternatives(1) man page for details.

Warning

Do not install the Java runtime under a directory path that includes whitespace. For example, the path, C:\Program Files\Java\jde7, is not an acceptable install path and will lead to unpredictable errors in Red Hat JBoss Fuse at run time.
