I recently gave a talks on the behaviour of different JPA frameworks at W-JAX(Germany) and TheServerSide Java Symposium (Prague). As some people have asked me, I am publishing the samples as well. I would also give away the eclipse project, however with all the third party libraries I am sure I will end up not [...]]]></description>

Distribution and communication between applications and services is a central concept in modern application architectures. In order to profit from distribution you have to keep some basic principles in mind &#8211; otherwise you can easily run into performance and scalability problems. During development these problems often do not surface.  Then suddenly in load testing or [...]]]></description>

On a recent project I had to call Java REST services from a .NET Client. Several problems came up &#8211; ranging from authentication to hidden performance issues. I want to share my lessons learned and encourage you to share your own opinions and experiences on this topic.

Memory Leaks and other memory related problems are among the most prominent performance and scalability problems in Java.  Reason enough to discuss this topic in more detail.
The Java memory model- or more specifically the garbage collector &#8211;  has solved many memory problems. At the same time new ones have been created. Especially in J EE [...]]]></description>

In my previous blog post I discussed that interoperability is not just about letting systems talk with each other. Having the technology to connect different platforms is only the first step. One major problem in heterogeneous systems is the lack of a common set of tools that enable you to easily find the root cause of a [...]]]></description>

Microsoft and Sun recently announced their Open Source Project Stonehenge at the JavaOne conference. Stonehenge is a reference implementation that shows how to bridge the two major development platforms Java and .NET using Web Services. This initiative definitely puts the spotlight on heterogeneity and the challenges that come with it.
Interoperability on the platform level is [...]]]></description>

I already listened to a couple of talks on the cloud. The whole cloud topic start to grow up, meaning more and more application scenarios for the cloud are appearing.
Yesterday there was a very useful classifcation of cloud services. The differentiated cloud services at a couple of different levels.
