No Web Start for 64-bit Sun Java

Sun does not include Java Web Start in its 64-bit version of Java. It appears that Sun thinks that you are not supposed to run Web Start on 64-bit machines, since these mostly are servers (?), and... eh... sorry, I cannot follow their reasoning. Let's hope they change their minds.

I haven't tried it myself, but here is a description of how to run 32-bit Java Web Start on 64-bit Ubuntu.

Update: At the time of writing this, an AMD64 version of Java Web Start is at the top of Sun's Request for Enhancements list.

Update: There will be support for 64-bit Java Web Start in an upcoming release, 1.6.0_12 (I think). Ismael Juma points out that an early access release is available. See his comment below.
