A few more developers have picked up Japex in the last month, and a couple have asked me to provide additional features for their benchmarks. I'll use this blog to introduce a couple of new features in Japex version 1.1.4.

And, naturally, the "binary XML" threads have resumed on xml-dev and in a few other places. Without trying to address all the questions raised in those threads, I'll talk about how EXI compares to Fast Infoset.

The discussion is still ongoing and we have actually written some Java interfaces to solidify our ideas. These interfaces are now available as part of the Woodstox subversion repository.

We kept hearing from many of you about how good the Woodstox XML parser was, especially how well it performed. Your voice has been heard, Woodstox is now officially part of Glassfish and this is the story of how it happened. spericas 2007-06-01T08:59:23-08:00 http://weblogs.java.net/blog/spericas/archive/2007/06/w3c_exi_perform.html The W3C Efficient XML Interchange (EXI) Performance Testing Framework is now publicly available for download. This is the testing framework used by the EXI WG to evaluate properties of "binary XML" candidates. Specifically, the framework can be used to measure Processing Efficiency and Compactness, and includes support for in-memory and network testing. It is also a great example on how to build a benchmark using the Japex framework.

There have been a few important bug fixes but the main driver for this release has been a problem found using the 1.4.1 RI on top of JDK 1.4. We discovered this last week while integrating a few bug fixes into an update release of JDK 6. Read on if you have plans to use the latest RI on top of JDK 1.4.

We hope this discussion will serve as the basis for a proposal to be incorporated in the next release of the API. Subscribe to the mailing list (it is moderated) if you are interested in influecing this next-gen API.

We have received some interesting feedback (see comments in the alluded blog) but feel many of you haven't had a chance to voice your opinion. I've created the community wiki page for this very purpose.

This is an update release to the FCS version that we released a few months back, and that is also included in JDK 6.0. The change log shows that approximately 36 issues have been addressed in this release. Thanks for your help on improving JAXP! spericas 2007-03-21T07:22:27-08:00 http://weblogs.java.net/blog/spericas/archive/2007/03/japex_11_is_now.html 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 (more on this later), I thought it was time to make this the official 1.1 release.

I saw this quesion raised in the Java Technology and XML forum, and at least 3 bugs were filed about this in the last few weeks. I'll use this blog entry to explain what the problem is and how to easily fix your code.

This is our first release since FCS back in April 2006. In his new blog, Joe Wang has already talked about this new release as well as some of the fixes and features in it. SJSXP is the underlying parser used in Glassfish as part of the JAX-WS runtime. I'll elaborate on one of the performance improvements aim at processing small messages at a high transaction rate. spericas 2007-02-20T09:01:27-08:00 http://weblogs.java.net/blog/spericas/archive/2007/01/whats_next_for_1.html The XPath API has been part of JAXP since version 1.3, which is part of Java SE 5.0. Yet, we've never received (or at least I haven't heard) much feedback about it or the implementation that we have in the RI. Well, that's not entirely true, I have heard a few times that the implementation is not very fast (which is true), yet not much about the API itself. As we continue exploring ways of making JAXP easier and faster, we'd like to get your feedback! I thought I'd write a blog for that.

Ah, and don't forget to catch all those exceptions or your code won't even compile. Is all the complexity of current API really necessary?

JAXP 1.4 is maintainance release of JAXP 1.3 with added support for the Streaming API for XML (StAX), and it is also the release included in Java SE 6.0. Community spericas 2006-12-05T07:21:53-08:00
