Java Web Services and XML

WS-Addressing 1.0 Core and SOAP Binding documents are in Last Call and the review period ends on May 11th.

The past month has been hectic for me, between my wife delivering a baby and me delivering the JAXB RI 2.0 EA. I lost the race by about a month, but finally today we released the early access of the JAXB RI. This early access basically implements the JAXB 2.0 specification early draft 2 with some differences. The EA passes almost all the tests that we used for testing 1.0.x series of the RI,...

WS-I Sample Application 1.1 EA is a rewrite of the WS-I Sample Application 1.0 using JAX-RPC 2.0 features and is available for download here. This bundle, as always, comes with the source code, ant build script, customization files, and other artifacts required to build the sample application from scratch. The bundle comes with the updated documentation. The source code has been commented through...

JAX-RPC 2.0 Standard Implementation Early Access is now available. This release is a big leap from JAX-RPC 1.1 in terms of the feature set: Data binding using JAXB 2.0 Annotations for specifying metadata Standard customization framework instead of the configuration files Improved handler framework Dynamic client and server Asynchronous clients See Doug's blog about details on each feature. The...

Doug reports that the binaries for the EA for JAX-RPC 2.0 are out. I'm sure Kohsuke or Sekhar will have a corresponding blog on JAXB 2.0. The downloads are off the correspoding Java.Net projects: jax-rpc and jaxb. Please give us feedback!.

The JAX-RPC 2.0 Standard Implementation Early Access has just been released to the JAX-RPC project and you can download it here. I would like to highlight some of the new features available in this release here. JAXB data binding JAXB 2.0 Early Access is also available. JAX-RPC 2.0 uses JAXB for all of its data binding. This means that much more of XML Schema can be handled compared to JAX-...

XML Schema is THE type system of web services. Learn it, use it, live it; don't hide behind Java->WSDL tools. More to the point: JAX-RPC Java->WSDL mechanical translation tools should never be used. Java-to-WSDL is a stunningly poor choice when you want to exchange data with another organization through web services. Think about it: you're going to translate a Java interface in to the XML Schema...

JAXP is the core API for XML processing in the Java platform. The latest version is JAXP 1.3 which is in bundled in Tiger and is also available unbundled for older JVMs. Those implementations were frozen sometime before the final round of integrations into Tiger and were overdue for an update with the latest changes Xerces and Xalan. The JAXP team just finished that integration; the sources are...

If you have not visited the page recently, I suggest you go there and take a look. Hmmmm, "Core Java"... yes, we all know about that. "Desktop Java"... yes, wonderful technology, many of us use it every day. "J2SE Embedded"... what!? J2SE Embedded? Where did that come from? While much of the Java community has been busy battling in the J2EE/.NET wars, the Law of...

Java Enterprise

Anyone who has used Flickr, GMail, Google Suggest, or Google Maps will realize that Web applications are not limited to plain and boring HTML-only user interfaces anymore. These applications provide very slick UIs and the hot, but not-so-new, technology behind them is Asynchronous JavaScript and XML (AJAX). We, the Java BluePrints team at Sun, are starting to address this area by developing a set...

Java Desktop

Everyone knows that Java's mantra has always been "Write Once Run Anywhere" (WORA) and there has been a lot of discussion over the years about that claim. Putting the WORA discussion aside (it's already been beaten to death), I see the real value being in that Java, itself, seems to run everywhere. No matter where I need my application or data to get to; desktops, servers, wireless devices,...

For the past two months or so, I've been working with some of the JDNC developers on the databinding problem. After some false starts, the approach we've taken is to define "data aware" components and some special encapsulation classes for relational data. The overall goal is to make forms and master/detail applications relatively easy to build by automating most of the donkey work involved...

There are a few questions in the world that you can pretty much get guaranteed answers to: Would you like a lot of money? Would you like a sock in the mouth? Do you want the last donut? In our geeky corner of the universe, we have similar "Well, duh!" questions like: Do you want Java to start up faster? Do you want your Java application to take up less space in memory? Do you want...

These days I tend to press F5 in my favorite browser every couple of minutes. I'm visiting the NetBeans page and cannot wait the delivery of NetBeans 4.1 since the release branch is known to be taken. Sure, 4.0 has been a big step in the development of NetBeans, but from my point of view (J2SE) introduced a lot of difficulties. I cannot judge how the benefits have been to the J2EE world, but I...

In working on my JavaONE presentation, I got to thinking about why frameworks such as the NetBeans Platform and Eclipse RCP are important. It's really because, if they didn't exist, we'd all end up rewriting them, anyway. Every project I've ever worked on started out as a dedicated application, with a very simple architecture. Then, as features are added, and they don't fit nicely into what I...

I spent this last Wednesday in NYC on what was probably the first nice day of Spring this year. I arrived from Connecticut via Amtrak into Penn Station. Generally, I take the subway up to the Sun offices near Grand Central Station, however, it was too nice of a day to be underground, so I decided to walk. It was close to lunch time when I arrived and the parks were overflowing with folks soaking...

Java Tools

Swing is slow, right? That seems to be a common perception which fast Swing apps like LimeWire seem unable to shake. Even the Jackpot GUI app is sluggish these days, and we all know it cannot be that my code is at fault, right? I think the real problem is that yours and my computers are too fast, or at least too fast relative to our customers' systems. Because software developers and quality...

Exceptions (and their stacktraces) are one of the features that first attracted me to Java back in early 1995; C++ obviously had exceptions, but I never worked with any C++ projects that used them as effectively as the Java core classes did. I find well-designed exceptions to be a significant productivity booster. My first project on the JDK team was developing the debugger API, and I think it...

Java Patterns

Weakly typed sudo java delegate implementations seem to be a dime a dozen these days. After reading the latest article on JDJ about yet another weakly typed implementation for java delegates I decided it was high time to put my brain to work on implementing strongly typed delegates. With a little imagination and some magic it was quite simple,...

Voice over (My)JXTA is now being opened up for broader testing. Here's a snap: If you are interested in trying this feature out feel free to inquire within the MyJXTA community or fire off an email to the myjxta dev list. If you aren't interested, heck, stopy by and tell us just how not interested you are. MyJXTA :: use it - learn it - do it Java == platform independence XML ==...
