Apple has released the free Mac OS Runtime for Java 2.0 (MRJ) for users of Mac OS 8.0. MRJ enables your Macintosh to run applications written in the Java programming language from Sun Microsystems. MRJ 2.0 implements Sun’s Java Development Kit (JDK) 1.1.3 and supports all the features of the JDK 1.1 specification, including Java Beans, Java Database Connectivity, Remote Method Invocation, Java Native Interface, and more. MRJ 2.0 also includes PowerPC and 68040 just-in-time compilers for significant performance improvements. Apple claims that MRJ 2.0 has passed every test in Sun’s Java Compliancy Kit. MRJ 2.0 currently does not support versions of the system software prior to Mac OS 8.0, although you can install it under System 7.6.1 using the Custom Install option. Apple says it plans to provide official support for System 7.6.1 in early 1998.
