I only recently discovered the different JVM's on the wiki page and thought I'd start tinkering. Its been difficult to find documentation on how to configure Java on Ubuntu though.
Lets say I wanted to change the JRE or JDK that I'm using, I could crack open a terminal and say
sudo update-alternatives --config java
And then pick from one of the installed versions.
If I'm understanding JVM's right (which I may very well be not), You can configure the openJDK to use alternative JVM's (Eg JAMVM) and run it as such
jamvm -jar foo.jar
2 questions,
1: Do i have the concept of a JVM right? As in, is this possible?
2: If so how do i configure the JVM and switch the default to a JVM of my choosing?
