Does Sun JDK have 64 bit binaries?

[Salman Ahmed]

Yes, 64-bit Java (JDK) binaries are available. When you go to the JDK download 
page, select "Linux x64" as your platform, and after that select 
"jdk-6u21-linux-x64.bin" from the list of available files. Once downloaded, copy 
this .bin file to /usr/local (or /opt) and make it executable and then launch it 
as ./jdk-6u21-linux-x64.bin to start the installation process.

The JDK should end up getting installed to a directory named jdk1.6.0_21.

You'll know if you installed the 64-bit version when you run the JRE without any 
options (i.e. java) and it's usage indicates that the following options can be 
used:

    -d32          use a 32-bit data model if available

    -d64          use a 64-bit data model if available

HTH,

Subject: [TLUG]: Does Sun JDK have 64 bit binaries?

Afternoon,

Wonder if someone know if there is a 64 bit java. The reason I ask is,
I headed out to Sun website, downloaded what apparently looked like a
64 bit jdk but when I extracted it, all I find is 32 bit RPM.   How do
you guys check if the version installed is 64 then?  I googled, but I
can not find an article that explain the 32 bit RPMs.  This is on
Centos 5.5
