How can I use JVM Client Mode on x64 operating system?

Question

I need to run the Oracle JVM in the "client mode". Is there any option to do this on an x64 operating system?

I installed Oracle 7 JDK per apt-get. It installed the Oracle JDK and JRE x64 edition. So i have only /usr/lib/jvm/java-7-oracle/jre/lib/amd64/server directory and no amd64/client directory.

On the Oracle website, you can download the JRE Linux x64 and x86 packages, precompiled. I download them both and looked into the folders.

x64 package contains only amd64/server directory. x86 package contains i386/server AND i386/client directories.

So, what can I do to use the client mode? Have I install the x86 edition of java? I think I can do this only manually and not with apt-get because it recognize that I have a x64 operating system.

Thanks!

AFAIK the 64bit version of the Oracle JVM only supports the server mode at the moment (my guess is we'll never see a client version). This FAQ would see to support that. I don't think the Open JDK project has a 64bit client version either but it's been a while since I checked: this post confirms my suspicion. It seems the server VM is as good as or better than any dedicated client VM would be.
