Java for Mac OS X

A Java runtime environment must be installed before installing jLog. Mac OS X 10.5 and 10.6 comes with one or more Java Runtime Environments pre-installed. Mac OS X 10.7 will propose to download Java after installation. Do just that.
Note that jLog V 5 requires Java 1.6. Apple supplies this version only for Mac OS X 10.5 - 10.8. Mac OS X 10.4 users may try the SoyLatte Java.

Frequent upgrades to the newest revision is recommended as this usually provides both visual and performance improvements as well as bug-fixes.

Please note that you must install Java with Administrator privileges.

Please note that if you install a new Java version, you may have to install the RXTX-files again (see the jLog Application Download page).

Java updates for Mac OS X are downloaded and installed automatically using the Mac OS X Software Update.

jLog can switch between different Java versions as described here.
