Some time ago I decided to familiarize with Google App Engine capabilities. Lately I read a document about GAE Java SDK version capabilities. I was surprised that a big part of JEE stack is supported e.g.: JPA and JSF. That moment I decided to make simple JSF-based demo application.
I use Ubuntu as operating system on my development machine. I keep my system up-to-date and apply patches and upgrades to new releases as soon as they are available for download. After upgrading to Karmic Koala 9.10 I noticed, that all my development tools based on Eclipse (STS, RadRails, Aptana Studio) are experiencing same problem: buttons on most dialog boxes (wizards, properties windows etc.) could not be pushed any more using mouse. Of course keyboard shortcuts still worked.
I’m using EclipseLink as JPA provider in some of my OSGi based projects. Latelly I also switched from Apache Commons Logging to SLF4J (shortly speaking not to be forced to write LOG.isDebugEnabled() in case of debug messages in my code). Then I found out, that EclipseLink is using it’s own logger which can not be configured using standard log4j.xml file.
