JAVA-CONFIG

NAME

java-config - The Java configuration tool for Gentoo

SYNOPSIS

java-config [options]

DESCRIPTION

java-config Is used to query/set properties of your system's Java environment. It can be used to list available VMs, java packages, set system default JVM and set user default JVM.

In addition, it is used by Portage as a common interface to querying properties about the various JVMs.

OPTIONS

-c --javac: Show full path to currently selected Java compiler.
-j --jar: Show full path to currently selected jar command.
-O --jdk-home: Show path to currently selected JDK.
-o --jre-home: Show path to currently selected JRE.
-v --java-version: Query current JVM for version.
-p [pkg1,pkg2,...] --classpath[=package1,package2,...]: Calculate classpath for a package.
-e filename --exec=filename: Figure full path to one of the JDK/JRE utilities, such as keytool , rmic and others.
-l --list-available-packages: List available Java packages. Used for selection by --classpath , --set-system-classpath and --set-user-classpath
-L --list-available-vms: Lists available JVMs. Used with --set-system-vm and --set-user-vm
-S <vm-id> --set-system-vm=<vm-id>: Sets the system-wide default JVM.
-s <vm-id> --set-user-vm=<vm-id>: Sets the user-specific JVM by putting all necessary env vars into $HOME/.gentoo/java-env .
-A <pkg1>,<pkg2>,... --set-system-classpath=<package1>,<package2>,...: Sets the system-wide default CLASSPATH.
-a <pkg1>,<pkg2>,... --set-user-classpath=<package1>,<package2>,...: Sets the user-specific CLASSPATH by putting all necessary env vars into $HOME/.gentoo/java-env-classpath (sourced from $HOME/.gentoo/java-env).
-X --clean-system-classpath: Cleans the system-wide default classpath, leaving only vm needed jars on it.
-x --clean-user-classpath: Cleans the user specific classpath that was specified by --set-user-classpath by deleting $HOME/.gentoo/java-env-classpath .
-n --nocolor: Turn off all colors.
-P <vm-id> --print=<vm-id>: Print the environment information for the specified virtual machine.

NOTES

You can get the <vm-id> that is used with --set-system-vm=<vm-id> and --set-user-vm=<vm-id> in the output of java-config --list-available-vms inside the brackets. Ex. [blackdown-jdk-1.4.1] and you can use this to set your default Java Virtual Machine.
