We are branching out from our successful on-site training courses to provide public courses. From current demand, our first course is likely to be in London, UK. If you are interested in Java performance training in London, please contact us.

1.5 seems to be nearly a year away? So I hear. And 1.6 is likely to be three years away. So if you want to get any features voted in to 1.5 you'd better do it now. Misha Dimitriev, the author of the JFluid technology I mentioned last month, wants your help to get JFluid technology voted in to 1.5. In case you forgot, this is a Sun project, and the technology would enable standard HotSpot JVMs to be dynamically attached to at any time for profiling. No slowdown when not attached, but profiling possible at any time. That looks pretty good to me. Go and vote (needs account, registration is free, it may take a couple of days before the bug appears in the database).

We are trying to move to a more weekly publishing mode. The newsletter will still only be emailed once a month, but individual columns will become available earlier, on a weekly basis. Plus we should have some new tips every week. You can track this by visting the home page or the newsletter page if you like to get your updates more frequently than once a month.

Get a free download of GemStone Facets 2.0 and see how this
patented technology supports JCA 1.0 to seamlessly integrate
with J2EE application servers to enhance performance.

This year, I've decided to extract the tips from the JavaOne presentations. I don't normally, because despite the 20-30 or so performance related presentations available each year, the target is broad based education; the presentations rarely have anything new to say about performance in the way of new tips, i.e tips that are not already detailed here at JavaPerformanceTuning.com.

And despite this year being the same, I felt that the interest surrounding Java's premier annual event justified spending the time on the JavaOne presentations. Certainly they are interesting, especially the architecture case studies. It is good to see that Java is the basis behind so many really big enterprise sites (EBay, CapitalOne, WSJ.com, more). So check the presentations I've covered, and with our new weekly format, I'll cover more in the coming weeks.

We also present our regular features this month. Kirk's roundup covers garbage collection, store checkouts, stateless beans, and much more including a really curious synchronization code snippet. This month's interview is with Philip Aston and Peter Zadrozny of BEA Systems. Our question of the month is about using import statements;

Javva The Hutt is on holiday, but of course we have nearly 100 new performance tips extracted in concise form.
