The JRE (Java Runtime Environment) only has the Runtime tools.
You need to install the JDK.
It works on my system:
**
jo...@eve ~ $ java-config -L
The following VMs are available for generation-2:
*) Sun JDK 1.6.0.17 [sun-jdk-1.6]
VMs marked as Build Only may contain Security Vulnerabilities and/or be EOL.
Gentoo recommends not setting these VMs as either your System or User VM.
Please see http://www.gentoo.org/doc/en/java.xml#build-only for more
