We have quickly concluded that it is no error at all, it is in the nature of the XML processing tools, but if you encounter it at the first time, it could seem strange. It is about the fact that XML text nodes are not necessarily processed at once, and while you read the XML, you might receive only fragments.For example if http://oktech.hu/blog/2009/08/concept-behind-fragmented-xml-text.htmlistvan.soos@gmail.com (István)0tag:blogger.com,1999:blog-941090960989175786.post-7777798874721284996Mon, 24 Aug 2009 06:45:00 +00002009-08-24T08:45:00.279+02:00devthreadcpu timeprofilingoktech-profilerThis blog entry explains a little technical detail about our commercially supported open source Java profiler, as part of a series of blog entries around the product.When profiling applications, it is always important to measure the time as precise as it can be, and the old way was to measure the system clock with increasing granularity, while in the meantime we have received access to a more http://oktech.hu/blog/2009/08/profiling-java-application-measuring.htmlistvan.soos@gmail.com (István)0tag:blogger.com,1999:blog-941090960989175786.post-5671467707901760932Tue, 18 Aug 2009 07:00:00 +00002009-08-24T08:20:04.274+02:00devautomationprofilingopensourceoktech-profilerIt is a great pleasure to announce our open-source product: the OKTECH Profiler.

Wicket is an easy-to-use, well-designed framework and is able to incorporate Ajax in a very nice and easy way. I personally am not a big fan of using Ajax in every corner of the application, however at some points it can make your app much nicer.
