java.net - The Source for Java Technology Collaboration

You can Vote... on GlassFish Bugs!
Over on The Aquarium, Eduardo Pelegri-Llopart points out that You can Vote... on GlassFish Bugs! "I didn't know that CollabNet's Issue Tracker supported votes on bugs. You will need a Java.Net id, but you can go to your favorite bug (like this one, for example) and cast your vote(s); it looks you have a budget of 10 altogether (I've used 5 of mine so far). Issue tracker also supports votes in queries: here are the GF bugs with At Least 5 Votes."

JSR 286: Portlet Specification 2.0
JSR 286, Portlet Specification 2.0, has posted a proposed final draft.

Re: EJB3 Observer pattern
As I'm sure you realized, a lot of these patterns are pretty simple to pull off. While we may look to things like the container to already handle these things for us, or something larger like JBI, may times just rolling out something quick and specific to the task is more than enough to get the job done and move forward. The key is simply keeping the abstractions in mind and staying as close to them as practical. Later, even if the underlying technologies change, the abstractions very likely remain the same, so there's little conversion cost later if you do indeed come up with a new need or a better solution in the future. —

Re: [BD-J-DEV] BDJ under the hood
Implementation techniques are not mandated by the spec, but purely interpreted implementations have all but disappeared. But really, this isn't the right question to ask - equally or more important is processor speed and other aspects of the underlying hardware, like memory bus bandwidth (for graphics blt operations) and classloading speed. Some players are much faster than others; the BD spec does set some recommended minimum performance levels, which helps. —

Can't connect to the native embedded browser
I have problem when using JDIC 0.9.3 on Linux with Mozilla 1.8a4. I got the following error message: "Can't connect to the native embedded browser. Error Message: Maximum retry number reached!" But sometimes, it works... Can anyone suggest what's wrong with it? —
