Java Web Services and XML

Tom Koulopoulos was the keynote speaker at a conference that I attended last week. He's a really bright guy and a very entertaining speaker (or at least I think so). Tom covered a wide range of topics, one of which was in dealing with uncertainty. He began with a question to the audience: "What are some games that involve uncertainty?" Audience members tossed out three examples: Dice Cards...

Phew, finally I could get an Indigo client to invoke an Indigo Web service. Here is the client code that worked: using System;class HelloClient {  public static void Main() {    HelloServiceProxy myProxy = new HelloServiceProxy(                         ...

Now that my Indigo Web service is correctly deployed, I tried importing the metadata and generate a client proxy. I tried the following command: "c:\Program Files\Microsoft IndigoPreview\SvcUtil.exe" /config http://localhost/gettingstarted/HelloService/mex but it gave an error: Generating files...E:\arung\indigo\client\outputError: Unable to save config to file 'E:\arung\indigo\...

Searching through Microsoft's newsgroup I was very thrilled to see that atleast one more person faced the exact problem I reported earlier. Additional (read more updated) release notes for Indigo are available as well. Scroll to the bottom of the page and there are links to winfx newsgroups, Web-based Indigo newsgroup can be accessed here. There are responses from Indigo team in the newsgroup,...

W3C WS-Addressing WG met F2F in Sunnyvale last week. Fujitsu graciously offered a conference room in one of the their buildings (they offered free lunch too :). Minutes are posted to the public-ws-addressing list. Paul Downey posted some photographs from the F2F.

BEA, IBM, Microsoft and TIBCO Software announced a week ago that they will Submit Web Services ReliableMessaging (WS-RM) Specification to OASIS for standardization. This effort is supported by a wide range of companies and organizations, including Sun. The co-authors proposed a new technical committee and charter for standardization of WS-RM. OASIS will have to figure out what do with WSRM, an...

The JAX-RPC 2.0 SI has been re-architectured since 1.1. The new architecture will make it easier to add new capabilities in the future. The new architecture allows for: Multiple Transports  - EA currently supports HTTPMultiple Encodings  - EA supports XML as text.  - The next EA will include MTOM/XOP and Fast InfosetMultiple Protocols  - EA supports SOAP 1.1  - The next...

JAX-RPC 2.0 EA was released few days ago and was supported only on Sun Java System App Server 8.1 container. This blog tells you how to install JAX-RPC 2.0 EA over JWSDP 1.5. The main advantage of being able to install over an existing JWSDP 1.5 installation is that you can alternatively use Tomcat as your container, in addition to Sun's Application Server. Theoretically, you should get support...

Mac Java

I've just installed Mac OS 10.4.0 and added the J2SE 5.0 R1 available from Apple. The 5.0 release installs alongside the 1.4.2 release. However, after that installation, I had problems with the 1.4.2 producing error messages: $ java -version HotSpot Error: update_sharing has failed java version "1.4.2_07" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_07-215) Java HotSpot(TM)...

~ 12 hours ago i upgraded to macosx v10.4. here are my first impressions.. terminal/shell i/o is faster eclipse editor is faster eclipse command completion mysteriously works now. i mean, it worked before but half the time it would complete something entirely erroneous; not anymore! (that used to be the most annoying thing for me. i didn't expect the upgrade to fix that. i can't tell you...

Java Desktop

I talked to many developers recently about the Windows JRE download size issue. The conversation often went like this: Stanley: What do you see as the major obstacle of your deployment? Developer: JRE download size is definitely a problem, especially on Windows. Stanley: Why? Developer: The JRE is 25MB, and it is beyond what most consumers are willing to download. Stanley: Actually, the full...

If you are interested in hardware acceleration for Java2D on Windows, check out the latest bits on the mustang site ( http://mustang.dev.java.net). Dmitri Trembovetski has been working tirelessly to implement functionality similar to what Chris Campbell did with our OpenGL rendering pipeline, and it's pretty stunning. There is now (as of build 33) acceleration for everything from the standard...

During the post-Tiger planning, we talked to numerous developers to determine what features and enhancements we should work on in Mustang. Many feedbacks we received are related to the user experience in Java Web Start, especially around the security warning dialog box for signed application.Why is security warning necessary? A signed Java application is simply just, signed. It does not mean that...

As everyone on this side of the galaxy must know by now, Tiger, version 10.4 of Mac OS X (will they ever hit Mac OS XI?), has finally arrived. If you're a Mac head like me you've been eagerly awaiting it at least since the previews last summer, if not from day 2 of 10.3's release. You will certainly be inundated with reviews, praise, and 'news flashes' about Tiger so I won't contribute to the...

JXTA

While we keep hearing about the misuse of P2P technology for sharing copyright materials in the press, it is nice to point out that there is more to P2P, and P2P presents unique values and capabilities to build scalable, dynamic and highly reliable network infrastructures. The JXTA open-source community is continuing its growth and successes building the leading open-source P2P platform. Today,...

Global Education and Learning

We have another crop of new projects in in the Global Education and Learning Community (GELC). This week we have a system to publish theses, a Bliki written in Java, a Java Exam simulator, masters thesis investigating an agent-based privacy directive, a recorder that watches you work and listens to your speech, a compression database, language parser, and a purchase calculator. Take a look at...

Java Enterprise

J2EE 1.4 specifies the use of the Connector 1.5 Architecture as the basic mechanism to integrate JMS providers with J2EE 1.4 compliant application servers. However some JMS vendors do not provide a compliant J2EE Connector 1.5 resource adapter to enable such an integration. This project helps such JMS vendors to integrate with J2EE application servers by wrapping their JMS client library in a...

NetBeans

This week, Sun Belux invites me to a Technical Workshop, to celebrate the launch of NetBeans IDE 4.1. They organized a Technical workshop on May 25 (Luxembourg) and May 26 (Belgium). In the mail it was said Please feel free to forward this invitation to your colleagues. Because we are belonging to the same community, I can consider you as my colleagues. More details and registration on the...

NetBeans 4.1 Update: Hurrah! NetBeans 4.1 has "fixed" the replace dialog problem that I blogged about last year... Eclipse could limit "search/replace" to the selected text and NetBeans couldn't. The new "Replace" dialog allows you to limit the scope to the selected text: Many thanks to the responsible party. It's a small change, but one which really makes a big difference (to me). On...

As an example, I'll show you how to use XDoclet and Ant to integrate with the JBoss Application Server. I'll create the same project that JBoss uses in their tutorial. I'll be very surprised if you don't find the NetBeans solution easier to use then JBoss' own Eclipse based IDE. In the JBoss Eclipse IDE, the XDoclet configuration steps are extremely tedious (ejb, servlet), and would have to...
