Java Tools

An interview, Meet Peter von der Ahé, Tech Lead for Javac at Sun Microsystems, I did with Peter, Sun's tech lead for javac, discusses the Kitchen Sink Language, the Java Compiler API, and new ways of thinking about generics, reification, type inference for local variables, and lots more. If you want to experiment with javac, check out the Kitchen Sink Language. Peter has a lot to say: --...

Hudson continues to keep me busy. So here are some of the recent developments. 1.100 Release First, I just hit the release 1.100, which is 101st release of Hudson. I think that's a lot of releases. Generally speaking, I think "release early, release often" is a good thing, but OTOH I also realize that taking time to shake off bugs while holding off (potentially de-stabilizing) new features have...

Today, Geir Magnusson Jr., the Apache Software Foundation's VP of Java Community Process, issued an "Open Letter" to Sun Microsystems, addressed to Jonathan Schwartz. I put "Open Letter" in quotes because it reads like an ultimatum demanding a license they like to the Java SE 5 technology compatibility kit within thirty days (or else). This request/ultimatum seems to have...

Curious how much Java is a test-driven technology ? Few words for a background. The Java TM Compatibility Kit (JCK) is a test suite, used to verify if the Java standard is correctly implemented. The first JCK came out together with the first JDK from SUN, now this effort evolved into the industry-wide Java Community Process. The JavaTest TM harness is a test monitor, used in first versions of JCK...

Testing tools are starting to take up a sizable chunk of the Java Power Tools book, which is probably logical, as proper and efficient testing should play a sizable part in any development process worth its salt. I've added a new poll on web UI testing tools here - please take a look and let the world know your favorite web UI testing method!

If you speak Russian, check the agenda and descriptions of Java ME sessions. 'Java ME Testing' session description is in the end of the list, it concludes the Java ME track and Day 2. Slides and description for it were first created in the native language of Internet and IT, that we use at work and call English by inertia. I did a first pass of translation to Russian and found that for many...

Installing Hudson is really as easy as it can get, where the only container-specific steps are: How to deploy a war? How to re-deploy a war for upgrade? (Optional) How to set HUDSON_HOME environment variable, system property, or JNDI entry? (it only needs one of them, not all) (Optional) How to set system property to increase the server heap size? Yet the reports from users suggest that these...

Matt Raible asked me to work on a FishEye plugin for Hudson in my recent Hudson-related blog entry. Incidentally, my colleague Rajiv has been also asking for this feature (of being able to link to SCM browsers like FishEye, ViewCVS, etc) — so much so that he filed the same RFE twice! So I'm happy to announce that this long-standing RFE since August 2005 is finally implemented in the...

It is true that the most popular test format supported by many Java TM IDEs is JUnit and its variations like TestNG or J2MEUnit. Interested to compare JavaTest TM harness and JUnit ? JavaTest is a test harness, JUnit is a test format. JavaTest is created to manage test suites written in many different formats, JUnit is a specific format and API for test development. The comparison is invalid, it...

The IDE you use can arguably play an important role in your productivity as a developer. Does your IDE blend into the background and become a natural extension of your brain? Or do you struggle endlessly with plugins and unintuitive menu options? If there's a subject that every Java developer has an opinion on, it's this one. I've added a new poll on the Java Power Tools website: what Java IDE...

I've been following Brian Leonard's recent entries on JRuby/Ruby/Rails integration in the latest NetBeans milestone release. In my own tinkering to solidify what I've learned from Brian, I've found that there are a couple of showstoppers that will prevent me from using this suite for serious Rails development, for now at least. You see, Brian's JRuby example was ported directly from the...

It's been a while since the last time I blogged about Japex. Over the last year or so there have been many incremental improvements (resulting in 30 different releases) and with the recent addition of combined bar charts, I thought it was time to make this the official 1.1 release. I won't talk about all the features that we have added during the last 12 months, instead I'll concentrate on the...

One of the big selling points for Hudson has always been its ease of install. But recently it just keeps getting easier. The current installation procedure is what I claim "2 minute setup": Download the Hudson war file from its Java.net Release page Then run java -jar hudson.war Head to the hudson dashboard Play But then, human laziness is really infinite. Some folks can't even bother to...

At the Java Posse Roundup last week we had some wonderful evening sessions called Lighting Talks. During these sessions each participant had 5 minutes to give their entire presentation. This necessitates, of course, brevity and clarity above all. And of course, since this was the evening, we were all sitting around munching on BBQ, drinking beer, and laughing away during the proceedings. So in...

I've just added a poll on Load Testing on the Java Power Tools website. How do you load test your web applications? I'm a great fan of JMeter, but there are lots of other tools out there as well. Not to mention the heavy-weight commercial tools from the likes of IBM/Rational and Mercury. What tools do you use?

Apache Lucene project is now apparently using Hudson for their nightly builds. While looking at how they are doing, I noticed that one of them suggested using Bamboo because of a nicer JIRA and Confluence integration. So I decided to write a Hudson plugin for JIRA. It's famous enough, so I figured there are probably more Hudson users who'd enjoy such a plugin. JIRA has a SOAP interface, so it...

The Java Power Tools website includes, among other things, a new poll on Software Configuration Management (SCM) tools. I'm interested to see how Subversion compares these days to CVS. And who is using commercial tools like ClearCase, StarTeam and Perforce? Check it out here and see if your favorite tool is listed!

The Java Power Tools website includes, among other things, a poll on Continuous Integration tools. Many people have already voted, and I have had a lot of feedback on the tools listed. So, due to popular demand, I've added some more CI tools to this poll. Anthill, which I forgot in the first poll, as well as a number of commercial products. Although the book focuses on O/S tools, it must be said...

For some reason, the blogsphere suddenly noticed my year-old NLink project, so I'm getting a lot of traffic lately. Maybe I've never sent out the announcement, when I originally released it, so here it goes... Historically, JNI has been the only option to invoke native libraries. The problem with calling native libraries with JNI is that, for every method, you need to write a java method...

Earlier this week I posted a few polls on the Java Power Tools book website, about the tools people preferred in a number of areas: build tools, continuous integration, and issue tracking. So far, the pools are getting some interesting initial results. On the build tools front, Ant is in front of Maven 2, but not by that much. Cruise Control still seems to be the leader in the Continuous...
