MRJ : Java Glossary
I have left this tombstone entry for historical interest.
Was Apple’s Macintosh Runtime for Java, the Java runtime for MacOS computers.
Now Macs use Oracle JDK/JREs like most other platforms. Apple was always behind and
treat Java with contempt. Equivalent of the JRE (Java Runtime Environment)
on other platforms. Comes with MacOS system CD (Compact Disc)
as of MacOS 8. Version numbers are a bit screwy:
MRJ (Macintosh Runtime for Java) 1.0 implements JDK (Java Development Kit)
2.0 implements Java version 1.1,
1.1 implements JDK
runtime only — for development tools, you need the MRJ
SDK (Software Development Kit). Apple provides the entire JDK.
don’t have a separate stripped down JRE
for end users. Signed Applets don’t run in IE (Internet Explorer)
or Netscape, though they should in IE
5.0 and Netscape 5.0. In the meantime
you can test with the AppletViewer.
