Making Java's presence known at OSCON

The O'Reilly Open Source Convention has published its list of sessions, including its Java track. I mentioned before that I was on the program committee again this year, and suggested that the committee was looking for talks other than the usual "state of / update on" kind of presentations (which could easily be whipped through in lightning talks). Since Java is one of several languages with its own track at the conference -- along with broader disciplines like security, desktop, and webapps -- it's important for the talks to reach out beyond the usual interests and biases of the Java audience, to appeal to people who might primarily work in other languages, or not even care about languages, per se. If your talk is right for JavaOne, it's probably wrong for OSCON.

Fortunately, many of the would-be speakers got the message and proposed talks about how the open-source community has picked up the Java ball and run with it. This year's java.net-related talks include Dalibor Topic on ports and projects spun off of OpenJDK, Josh Marinacci on expanding the Java platform beyond programmers, and Roger Brinkley on extending, expanding, and porting Mobile & Embedded Community projects. There are also multiple Groovy talks -- a surprise to me, since I thought Groovy had one foot in the grave just 18 months ago -- and a ridiculously appealing talk on "Java Programming in a Multicore World", something I think would make a great article proposal (hint!) or perhaps even a book.


In Java Today, NetBeans.org has announced that a new version of the Plugin Portal is now available. New features include a verification process for publishing plugins on Plugin Portal Update Center built in NetBeans IDE, comment notification via email, comment management, and more. Further information about the portal's new functionality is available in the full functional specification.

Over on OEDN, a site for developers using OpenCable/OCAP/Tru2way to develop interactive television applications, Will Kreth asks Does Cable "Get It"? "It's a question that needs to be asked. Because, beyond the dichotomy of "Professionally Created Content" vs. "User Generated Content" (sometimes referred to as "UGC") -- we're rapidly moving into the territory of "User CONFIGURED Content." Content that is arranged, assembled and edited as drag-and-drop, click-to-install elements that represent the entertainment/social dashboards of their lives. The "Widget Nation" is here, and combined with the move to time-shifted video viewing, a powerful dynamic is at play."


In today's Weblogs, Brian O'Neill asks What Ruby could learn from Java? (and a bit of the vice-versa), time for a Ruby Community Process? "Ruby works on a much different development cycle, that relies on the code itself for documentation, and the blogosphere for consensus. This works well for rapidly developed low-risk projects, but is it right for the enterprise?"

Fabrizio Giudici digs into a Historic series of profiling data. "After fighting with some showstoppers in the NetBeans Profiler (involving RCP projects) and finding a decent workaround, I've started the tuning of the Metadata facility for blueMarine. I've already done tuning in the past, of course, but I have always had some frustration in how I easily lost the traceability of the thing."

Finally, in Hudson's SCM is just converted from CVS to Subversion, Kohsuke Kawaguchi announces, "the source code repository of Hudson has been migrated from CVS to Subversion yesterday."


In today's Forums, rajbirb has a complaint about referencing isolated session cache object from shared session cache object. "Can anybody tell me why Toplink Essentials chose not to allow shared objects in the parent server session's shared session cache to have a reference to isolated objects in an isolated client session's isolated session cache? Consider this scenario: A Customer entity has a OneToMany relationship with CustomerInventory entity. I know my Customer details cant be modified from outside but customer inventory can be. So i decide to make my Customer entity use shared session cache whereas CustomerInventory i want to fetch from the datasource always. But Toplink Essentials doesn't allow me this behavior."

Desktop Java developer alavideo wants help dealing with mac application quit (commad+Q) bypassing appframework shutdown() method. "I'm sure this has been asked before but searching this forum didn't turn up any results. What is the solution for getting the application framework to call the framework's "shutdown()" method when using the mac's application quit keyboard shortcut (command+Q)? The appframework automatically adds the proper keyboard shortcut to the "exit" menu, but using the shortcut just seems to exit the app without calling the framework shutdown() method."

Finally, komadori updates the status of one Java Kernel feature in Re: Partly offline installation. "Question 20 in the Java kernel FAQ (https://jdk6.dev.java.net/6u10faq.html#JKernel) reads "Is it possible to create custom bundle for Kernel install? We're actually going to be holding off on the custom bundle plan, for a lot of reasons, both legal and technical. ~". At least it hasn't been dropped completely."
