JAVA framework for XML data binding
We have a requirement to unmarshall very large file in JAVA.The size of the file is up to 10MB.Also the Schema validation against the XSD file
Currently,our choice is to use JiBX (http://jibx.sourceforge.net ) primary based on performance consideration.(see a pretty old performance tests at http://www-128.ibm.com/developerworks/xml/library/x-databdopt2/_
It takes less than 40s to validate a 10mb instead of 20mn with the XMLBeans library.
1-Do you have any suggestion of other JAVA framework which could perform as well as JiBX and which
are listed in the "core libraries" submitted to the domain council ?
- Thank you

I don't know of anything significantly faster than JiBX (although you could try Jaxb 2 and see how it fares). But pure parsing speed of a 10 MB document is in the order of 1 second (using streaming parser, with properly warmed up JVM, from fast disk etc), as fastest streaming parsers can get up to, say, 30 MBps parsing throughput. So it would seem like you could do better than 40 seconds; and I'd expect Xerces to be able to parse + validate in just few seconds (assuming schema is cached and reused etc). You could perhaps profile binding to see where time is spent.
Not sure if above helps, but I thought it's good to know that there's no fundamental reason why binding could not be improved from said 40 seconds.

Re: JAVA framework for XML data binding
I used JiBX 1.0.x on a project to load large XML documents of about 14 MB : it was taking like 4s to load the document on my development computer. This time was only with JiBX basic validation and no xsd validation though.
JiBX is a great framework and I had no problem using it. I can only recommend it.

Brian Goetz continues to lift the lid and peak into the inner workings of Java in Java Urban Performance Legends. In this article he exposes the fallacy behind some of the more common performance myths found in the annals of the JVM.

Looks like today AJAX concept have several interpretations. We can distinguish different approaches of AJAX integration. Can they co-exist within the same application? Can we talk about layered AJAX integration?

Artima has published a short article describing the Design-Time API for JavaBeans, which was recently approved as JSR 273. This API promises to bring VB-like ease to Java development, but may face a cultural bias among Java developers who tend to think more in terms of class libraries than components.

There is plenty of speculation today regarding a potential buyout of Sun Microsystems by Scott McNealy and Silver Lake Partners. How would privatization of Sun affect Java?
