Cay Horstmann: A First Look at NetBeans 6.7

2009-07-02T15:47:32Z

A few days after Eclipse Galileo, Netbeans released its latest offering, Netbeans 6.7. Here is a first look, as always from my entirely biased perspective.

David Gilbert: Apache Harmony and JFreeChart

2009-07-02T15:11:42Z

According to an article in SDTimes, Craig Hayman from IBM thinks that Apache Harmony is "ready for prime time". That surprised me (OK, not really) so I decided to give the latest release (milestone 10) a quick workout with JFreeChart. I ran various demos and concluded very quickly that Harmony is...drum roll...not ready. This also seems to be at odds with the general perception ...

Andrew Xuelei Fan: Enable OCSP checking

2009-07-02T02:55:43Z

If a certificate is issued with a authority information access extension which indicates the OCSP access method and location, one can enable the default implementation of OCSP checker during building or validating a certification path.

Jonathan Gibbons: Minor updates for jtreg

2009-07-02T02:38:15Z

Rémi Forax: JSR292 backport - First release

2009-07-01T17:06:23Z

First release of JSR292 backport. You can now test invokedynamic with your old :) JDK (1.5 or 1.6).

Roman Kennke: Java is a Doom Trojan Horse

2009-07-01T17:02:18Z

At least according to Symantec. I want to make a screenshot, but I don’t know how to do this in Windows XP. I probably need the Ultimate Edition or so. God, this crappy OS doesn’t even have the most basic functionality, or it hides it so well that nobody finds it. No, the print key doesn’t [...]

Mario Torre: Mixing of AWT and Swing

2009-06-30T22:33:11Z

Back to the code :)

Dalibor Topić: Conference Roundup: Jazoon 2009

2009-06-29T17:51:17Z

This year was my first time at Jazoon. It's a conference in central Europe in Zürich, Switzerland, a few weeks after JavaOne and almost 6 months away from Devoxx, the large European Java Event at the end of the year in Antwerp, Belgium. It attracts international speakers, and a diverse European audience. It has continuously grown in attendance, year after year, to more then ...

Mario Torre: Apache complaints

2009-06-29T15:22:09Z

With the release of OpenJDK, Sun donated to the World not only a big piece of Software and some gigazillion of men hours (and so money), they donated knowledge. This knowledge will be forever part of the humanity, because Java is a Free Software project now.

Dalibor Topić: Conference Roundup: LinuxTag 2009

2009-06-29T14:14:48Z

So, like I said in my last post, I went to LinuxTag again this year, to speak on OpenJDK. I was a bit surprised and flattered to find the talk announced in the regional German press, given that it was a 'regular' talk, rather then a keynote, so I wasn't quite sure what to expect.Since I had to be in Zürich for Jazoon ...

Stephen Colebourne: No Java SE 7 - US DOJ investigation

2009-06-29T09:39:31Z

There are signs that the US Department of Justice is interested in the Java licensing issues I've reported on recently.

Cay Horstmann: Upgrading to Eclipse Galileo

2009-06-26T17:54:41Z

I installed Eclipse Galileo and report on my upgrade experience--what I had to do to get plugins to work, and what new features I noticed.

Jeroen Frijters: IKVM.Reflection.Emit Update

2009-06-26T04:42:52Z

I have done a massive amount of fixes to IKVM.Reflection.Emit to make it full featured (even though it still doesn't implement all Reflection.Emit APIs, the functionality should (almost) all be there, for example via different overloads).

Andrew Xuelei Fan: An Aggregate of Feeds on Java Security and Networking

2009-06-25T15:12:50Z

To facilitate keeping track of blogs on java security and networking, I just created an aggregate of feeds, http://feeds.feedburner.com/javasec, and subscribed it to my feed reader, thunderbird. If you are blogging on Java security or networking, please let me know, I would like subscribe to your feed and add it into the aggregator

Clemens Eisserer: Only good news ;)

2009-06-25T15:12:00Z

Tomorrow my holidays begin, after my bachelor thesis presentation I will hold at the computer graphics institute at the Technical University of Vienna and an exam two hours later.Its basically the same presentation I held at Fosdem09, spiced up a bit with the most boring parts removed. Needless to say I prefer a 15min talk a lot over a 30min talk ;)A big ...

David Gilbert: Windows Vista in Multiple Languages?

2009-06-25T07:11:53Z

A few weeks back, I had to buy a laptop at short notice. In France. The laptop (a cheapish one) came with "Microsoft Vista Edition Familiale Basique" preinstalled. Everything in French, as you'd expect. I found the control panel and spent quite some time looking for the option to switch the display language to English. Modifying the country / region didn't change the language. There ...

Dalibor Topić: OpenJDK around the world - Jazoon, LinuxTag, FISL

2009-06-23T12:59:51Z

I am the Jazoon conference in Zürich this week. It began today with a keynote by James Gosling, and it's a fun event, that feels like a very laid back version of Devoxx executed with Swiss charme and attention to detail - same setting in a movie theatre, well working wifi, with a good list of speakers. I'm looking forward to jvanzyl's Maven talk later ...

Kohsuke Kawaguchi: Growth of Hudson plugin ecosystem

2009-06-21T23:56:10Z

A Hudson committer Seiji Sogabe put together a chart that shows the growth of the Hudson plugin ecosystem.

Amy Fowler: The Ultimate Craftsman

2009-06-21T08:00:28Z

Absolutely nothing about Java or JavaFX here. Just a small tribute to my pop for leading me down a path to geekdom.

Andrew Xuelei Fan: TLS and NIST'S Policy on Hash Functions

2009-06-18T11:15:55Z

March 15, 2006: The SHA-2 family of hash functions (i.e., SHA-224, SHA-256, SHA-384 and SHA-512) may be used by Federal agencies for all applications using secure hash algorithms. Federal agencies should stop using SHA-1 for digital signatures, digital time stamping and other applications that require collision resistance as soon as practical, and must use the SHA-2 family of hash functions for these applications after ...

David Gilbert: Free Google Beer

2009-06-18T07:39:51Z

One evening during JavaOne 2009, Google held a party at a very nice hotel in downtown San Francisco and Roman and Mario convinced me to come along - the only problem being that they had invitation cards and I didn't. The nice ladies at the door frowned a little when I said I didn't have an invitation, but I think Mario said some magic words ...

Roman Kennke: Things that happen, happen

2009-06-18T02:12:55Z

Short summary of happened and happening things: JavaOne2009: Great. Lots of faces to finally put on email addresses, IRC nicknames, etc. San Francisco: Great. Includes previous point. Plus: Seafood (oh my!). Extremely poor vs. extremely rich people. Lots of things that I almost got done, but not quite. Some photos. Cacio: Great: Of course. BOF went good, but [...]

Roman Kennke: Is there an artificial god?

2009-06-17T15:55:05Z

I know I am supposed to write about JavaOne, my new Job at Sun, the USA, all the cool stuff that happens in Cacio, etc, but this is probably much more interesting: Is there an artificial god?

Cay Horstmann: JSF 2.0 Refcard available

2009-06-16T20:03:46Z

DZone just published the JSF 2.0 version of my JSF refcard. It provides updated summaries of the tags and attributes needed for JSF programming, along with a summary of the JSF expression language and a list of code snippets for common operations.

Andrew Xuelei Fan: Publicly Accessible LDAP Servers

2009-06-16T14:31:35Z

In order to learn JNDI, one needs a LDAP server for various purpose. In the JNDI tutorial, there are a few of publicly accessible servers documented[1]. However, the list is too old, and those servers are out of services.

Éamonn McManus: JSR 255 (JMX API 2.0) is postponed

2009-06-16T14:31:21Z

Here is the text of the message I recently sent to the JSR 255 Expert Group, in my capacity as Specification Lead.

Cay Horstmann: My Department is Slashdotted

2009-06-16T05:12:58Z

I teach computer science at San Jose State University and found that my department just got slashdotted. An eager student posted all homework solutions for his data structures course, his instructor threatened to fail him, and the rest is history. It's good that there is no such thing as bad publicity. I discuss what it means to learn and teach computer science when all ...

Andrew Xuelei Fan: JSSE Troubleshooting: Certificates Order in TLS Handshaking

2009-06-16T04:45:19Z

Failed with a exception: java.security.cert.CertPathValidatorException: subject/issuer name chaining check failed.

Kelly O'Hair: Warning Hunt: OpenJDK, NetBeans, Warnings, and FindBugs

2009-06-15T23:37:01Z

Did you see Bill's FindBugs slides from JavaONE 2009? You should create some step by step directions on getting started with NetBeans, FindBugs and the OpenJDK. We need to get developers working on this. Humm, Ok, I'll look into that. Don't just "look into it", do it! Ok ok already, I'll "do it". And try and talk about how to fix warnings, and especially ...

Dalibor Topić: Jigsaw Feedback Roundup

2009-06-15T21:23:52Z

The JavaOne tech keynote demo of Jigsaw inspired a bunch of feedback on blogs:Alex Miller thinks the vision is pretty coherent:Peter Pilgrim thinks it made common sense:Bram Bruneel was impressed by the native package generation:Gerard Davison looks forward to a future without mandatory CORBA downloads:Floris Ouwendijk thought the keynote demo was very clear on the functionality of Jigsaw:Augusto ...

James Gosling: Jazoon!

2009-06-15T21:14:53Z

I'll be spending next week in Zurich at Jazoon'09. They've got a great lineup of technical sessions to pump your head full of all the latest everything. The lineup of speakers is pretty impressive. ...

Dalibor Topić: JavaOne Roundup : Jigsaw Falling Into Place

2009-06-15T20:07:13Z

This JavaOne was a bit different from last year's. In terms of sessions at JavaOne, I've only had a relaxed and interesting OpenJDK Porters BoF to host with my co-host, David Herron, so I could instead of hacking away on slides spend my weeks leading up to JavaOne on preparing the OpenJDK pod in the exhibition space, and happily hacking away on jpkg, a ...

Jeroen Frijters: IKVM 0.40 Update 1 Release Candidate 0

2009-06-15T05:40:05Z

A minor update.

Dalibor Topić: Movies: Star Trek

2009-06-13T16:46:37Z

There are young people playing leading roles, so the Star Trek movie is like a space road trip full of Wesley Crusher's space college friends. Which is actually a good thing, compared to other Star Trek movies. The movie is fun, at least for the first 80 or so minutes. The script takes care of providing regular comic relief to make the filler segments ...

Jonathan Gibbons: javac: plates, coins, and progress

2009-06-13T05:02:38Z

As we reported at JavaOne, a lot has been going on for javac over the past year.

Dalibor Topić: Books: William Gibson - Spook Country

2009-06-12T16:08:32Z

Gibson, Neuromancer, Cyberpunk, open drawer, close drawer. Well, not quite - Spook Country doesn't really have any super-futuristic gadgetry. It's set in the present, describing a post-9/11 world of dispersed, interconnected knowledge, where reality can have many layers, which ultimately end up meeting in the book. So far, so standard. A nice idea from the book is locative art, that takes the concept of tagging ...

Andrew Xuelei Fan: RSA AlgorithmIdentifier of X.509 Certificate

2009-06-12T14:53:36Z

By far, RSA is a most wide used cryptography algorithm. Both ITU-T X.509 and IETF PKIX WG define the RSA algorithm identifier, however, they are not identical. ITU-T X.509[1] defines the algorithm as:

While IETF PKIX WG[2] defines the algorithm as: ...

Hi all,

Rémi Forax: ASM now supports invokedynamic

2009-06-12T06:43:33Z

ASM 3.2 is released with the support of the new bytecode invokedynamic.

Dalibor Topić: Movies: Terminator Salvation

2009-06-12T01:40:23Z

There are a lot of amusing moments in this one - plenty of references to old Terminator movies, and many highly awkward sequences that feel mashed up from somewhere else. My favorite is the couple of minutes long monologue by none other then Skynet, explaining in typical Bond-villain style with a human voice to its unwitting human-turned-bot tool how its evil plans are unstoppable, only ...

Mario Torre: Back from J1

2009-06-11T20:45:28Z

So, I‘m not exactly in the mood of talking, because some personal things get over the fantastic week we passed in San Francisco.

Amy Fowler: Insider's Guide to Mixing Swing and JavaFX

2009-06-11T17:58:47Z

Responding to requests at JavaOne for more information about using Swing with JavaFX, I've written a 10 step guide for using JavaFX to create a not-so-extreme GUI Makeover for Swing applications.

David Gilbert: Site Licences and Support

2009-06-11T13:01:26Z

A few years ago, a company asked me if they could buy a site licence for the JFreeChart Developer Guide [if you are not familiar with the setup, the short story is that JFreeChart is an open source library licensed under the LGPL, and my company makes some money by selling documentation for it]. At the time, I'd only been selling single copies of ...

Chris Campbell: Effects in JavaFX: Chaining

2009-06-11T10:07:54Z

According to Eclipse community survey, Hudson is the most adopted CI tool.

David Gilbert: Back from JavaOne

2009-06-10T21:01:21Z

I got back from JavaOne on Sunday, all my travel connections worked out and my kids were happy to see me (and the chocolates from Ghirardelli). My birds-of-a-feather session on JFreeChart went well. There was a good turnout, people asked plenty of questions, and I felt like there was a very positive tone. Elsewhere at the conference, there were a lot of highlights although ...

Lillian Angel: OpenJDK Interim Governance Board

2009-06-09T20:59:10Z

As Simon Phipps reports, thanks to Mark Reinhold's tireless effort to put everything in place for the announcement, the OpenJDK Interim Governance Board has been expanded to include two new members, Martin Buchholz, and Andrew Haley. Martin is a software engineer at Google, who is very active in the area of core library development, and has been the first engineer outside Sun to ...

Kohsuke Kawaguchi: After-JavaOne project

2009-06-09T06:34:47Z

JavaOne is always such a big week for me (and many of us) that I need a bit of time to unwind before I go back to my regular routine. So this year, I took on a little hobby project.

Andrei Dmitriev: JavaOne presentation

2009-06-08T19:01:49Z

The Java One 2009 has finished that Friday. Below are the slides for the BOF-4743 .

James Gosling: JavaOne 2009: another amazing experience.

2009-06-08T18:27:37Z

This was another amazing JavaOne. It was also the weirdest: between the Oracle situation, the global meltdown, and the financial situation, it was very different. Early on, we were really concerned (==nearly paniced) that no one would show up. Almost every company that usually sends a crowd of people to JavaOne had travel restrictions that meant that few could attend. From what we had ...

Clemens Eisserer: Rewrite ... finally

2009-06-06T07:44:00Z

Finally the rewrite version is available in the repo.It is not production ready and still has a few known bugs.At least it builds ;)Took me ages to start fighting with mercurial, however turned out to be a lot less horrible than expected.The rewrite version features two different backends, for now only the native backend is functional.You can find more details ...

Cay Horstmann: Java One 2009 Day 4

2009-06-06T05:03:31Z

On Day 4, I report on the toy show, magical mystery tours, mistakes that matter, and how to bring the fun back into programming. (Maybe I am a sucker for talks with catchy titles.) In summary, it was a solid conference, and I look forward to Java One 2010. I conclude with predictions, one of which is that there will be a Java One ...

Maurizio Cimadamore: Rich diagnostics landed on javac

2009-06-05T16:10:48Z

I and Jon presented our langtools BOF - thanks for everyone who decided to attend despite the unfortunate schedule (we were running in parallel with the 'after dark' bash!). The BOF has been mainly focused on the javac diagnostic improvements in JDK 7 (which are currently in the langtools workspace and planned for integration in M4). We showed a demo which (I hope) gave a ...

2009-06-05T05:18:30Z

It's day 3 at Java One, and I report on Second Life, a JavaFX+REST lab, "it's not your father's von Neumann machine", Scala actors, and--an annual tradition--the packrat script for downloading all slides.

John Rose: Thursday at JavaOne
