Java runtime install confuses me

[Night Goat]

OK, I found a bit of documentation on how to install java. It said basically, emerge blackdown-jre. So I did that, and then I ran java-config since it made sense to at least give that a test run. I got a message saying that no Java installation was found, and to run 'java-config --set-system-vm=???' to set a system-wide installation. But nowhere have I found the right syntax for blackdown. I tried --set-system-vm=blackdown and --set-system-vm=blackdown-jre, but neither of those worked. The man page for java-config didn't go over the possible entries there either. If anyone who has installed a JVM successfully could reply and let me know what they did, that'd be great. I'm not married to blackdown, I just saw it in some other documentation. I'll remove it if it leads to a proper JVM installation.

run 'java-config --set-system-vm=???' to set a system-wide installation. But nowhere have I found the right syntax

Example:

Code: Select all

java-config --list-available-vms

produces the following output:


[blackdown-jdk-1.3.1] Blackdown JDK 1.3.1 (/etc/env.d/java/20blackdown-jdk-1.3.1)
[blackdown-jre-1.3.1] Blackdown JRE 1.3.1 (/etc/env.d/java/20blackdown-jre-1.3.1)


now you can go (as root)

Code: Select all

java-config --set-system-vm=blackdown-jdk-1.3.1

or

Code: Select all

java-config --set-system-vm=blackdown-jre-1.3.1

like it's shown in the square brackets.

Man, that worked. Thanks.
