Today I stumbled over a rather interesting issue in combination with JBoss, Hibernate, Spring, JPA and EJB.

First of all, we have mixed environment of EJB3 and Spring 3 using JPA2. All in JBoss 6 AS, with default Hibernate 3.6 as JPA provider. Now for a long time everything works fine until we re-organize the dependencies of our modules. Starting with that we got some strange JPA behavior like “class is not an entity” and some rather weird getter issues.

While the upgrade from Eclipse 3.6.2 to 3.7 went without nearly any trouble the upgrade of the Acceleo plugins to the versions provided with Eclipse Indigo was “a little bit more” problematic.

Finally we made it! openscada.org has been updated to look good and contain new information. Finally :)

Tooltips are quick way to add information to a widget that received the users attention. While one can argue about the pros and cons of tooltips this post focuses on the style of tooltips once you decided to use them.

If you are working as a software developer in a project based development environment you will, hopefully, encounter the day the customer wants to see the result that was promised to him. The worst thing that can happen is that after months of development you finally end up in a scenario of it is not working or it is not what we need. Sure there are numerous reasons of why this happened and what types development process you could have used. But often quality management and software development definitions are written once and never lived as described. developers consider it a burden that is unnecessary and is blocking them in their daily task of creating new functionality.
