[gentoo-user] no javac on gentoo amd64?

[Xi Shen]

hi,

my system is gentoo amd 64. java-config -L show i have two VMs on my system:

The following VMs are available for generation-2:
1)      IcedTea6-bin 1.7.1 [icedtea6-bin]
*)      Sun JRE 1.6.0.18 [sun-jre-bin-1.6]

but when i ran javac, it says:

* javac is not available for sun-jre-bin-1.6 on x86_64
* IMPORTANT: some Java tools are not available on some VMs on some architectures

we do not have javac on amd64 system? how to fix this?
i did not find much use information on http://www.gentoo.org/doc/en/java.xml

The JRE (Java Runtime Environment) only has the Runtime tools.
You need to install the JDK.

It works on my system:
**
joost@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 
information
