    The state of Java support is:

    - OpenJDK with Hotspot Zero (default): works fine, but there’s not JIT so it’s somewhat slow; I’ve found the performance of tomcat + webapps reasonable (after the first compile of JSP pages)

    - OpenJDK with CACAO vm (java -cacao): mostly ok, but has big problem with JMX (as in “crashes the application”); on the other hand cacao vm has a JIT, which means that when it works it’s much much faster than hotspot zero (tomcat startup time is reduced to about 1/3)

    - Sun EJRE: extremely fast and feature complete. However it’s *not free*; you have to pay royalties when deploying the system; furthemore the JRE is still in “early access” phase, it will expire after 90 days.

    Hello Kenny,

    Could you try if jdownloader is supported from this java release?

    Thanks for yuor awesome work ;)

    Jdownloader works but very slow and the CPU keeps running 100%.
    However, you can try tucan downloader provided you compile it and install the required packages (see Readme). It works very well with low consumption. The issue is that this soft manage only a small subset of what jdownloader can do.

    Hi. There seem to be a bunch of interesting entries in this blog, but all I see are the article titles and the comments. Am I missing something?

    It is possible to sign up and download a version from Sun directly :

    It works like a charm for me on armedslack-current.

    Cheers

    Hi, (I did not find how to tell you, so I made this offtopic comment),

    This post is related to the PLUG 3.0 that you are presenting on the top of your page. I guess you should want to share these information

    IONICS is presenting their new plugs, they have ploted a version with internal 1.8′ DISK and other wihtout disk but with 2 e-sata.

    We can find info at:

    http://ionics.wordpress.com/

    and

    http://www.ionicsplug.com/

    With the ‘cumulus’ (the one with 2 e-sata) we might have pretty good hard disk performance on a plug. I sent you a request (two weeks ago) to send me hdparm on yout plug

    Cheers

      Thanks for the heads up, I’ll update the front page with your information.

      ps. I reply to your request about hdparm in the sheevaplug performance page. Did you see it?

    Is there bluetooth support in OpenJDK on Sheeva Plug? I am new to Java thought javax.bluetooth is part of standard JDK. Is that true?

    There are some vendors who provide SD based BT solution.
