A new release 0.30 of MiniPauker, a J2ME flashcard learning application
I've just released MiniPauker v0.30, a J2ME application for learning vocabulary etc.
MiniPauker is like Pauker a generic flashcard learning program, but written in J2ME for the use with mobile devices which support J2ME with MIDP2 and JSR-75. MiniPauker is compatible with Pauker (import/export).

A logging wrapper around PreparedStatement to provide detailed info upon error
In my java web application I use JDBC to store data in batches into a database. When there is a problem the whole batch insert fails and it's difficult to find out what data caused it to fail. Therefore I've created a wrapper around PreparedStatement that remembers values passed into the various set* methods and can provide a comma-separated listing of all rows in the batch upon failure.
This is my LoggingStatementDecorator that stores values for later logging; based on java.lang.reflect.Proxy:

Lotus Notes 8.x under Linux: No window shows up, Tips for upgrading to LN8.5
Since recently when I started Lotus Notes 8.0.2 as another user via sudo, it has started with the splash screen, asked for a password nad displayed a progress bar but as soon as the startup finished and the splash screen disappeared it hasn't open the main window. The process was running but there was no visible manifestation of it.
After a long time and an upgrade to LN 8.5 I've figured out that perhaps there was something wrong with the configuration. The reason to think so is that LN8.5 exhibited exactly the same problem but for all users. Later I've discovered that there were some configuration files like /etc/notes/ and /etc/ibm-hannover.conf left from the previous version though I uninstalled it (maybe these aren't created during the installation but during first startup). After their deletion and LN8.5 reinstall it more less started to work.

[DRAFT] Maven "change" project extending a non-maven web project
Disclaimer: I'm rather new to Maven and thus my solution is likely not the best one. I welcome any improvement suggestions.
My current project here at IBA CZ extends a legacy non-maven web project and I had to devise how to organize the extension modules and other new modules depending upon them. The final goal was to create a portlet face for this servlet-only web application that is written in JSP and a strange presentation framework and then create specific portlets for specific needs.

Seam Tutorial 1.2: RichFaces and paged table (datascroller)
My aim in this tutorial series is to create a Seam portlet displaying data in a paged (and ideally also sortable and filterable, but lets be realistic) table running in the Liferay portal.

The Forgotten Hells or God Save North Korea!
I intended this as an exclusively technological blog but after seeing the movie Yodok Stories yesterday I feel I can't keep silent on the subject. I'm even more touched by the movie because the first years of my life I spent myself in a communist dictatorship though it was already in its last stage and can be by no means compared to the nightmare of Korea.
On this planet there are hellish places where human life or dignity have no value, where people live in such a suffering, fear, and pain that we perhaps even can not call them human any more. These places are well hidden from our sight though as the recent Fritzl case has shown, it doesn't need to be far away. I'd like to remind the world of two such places because pretending they do not exist only helps them to last longer. It's very good that everybody speaks about the human rights violations in Tibet but there are countries that need our attention even more though they may not be as attractive and "in".

When will we see JSR 286 in JSF portlets?
Since June 2008 we have the final release of Portlet 2.0 (JSR 286) specification bringing the long sought after features like inter-portlet communication (IPC - events, shared/public render parameters), support for Ajax (resource request), portlet filters and more. It's already implemented in the latest versions of leading portals including Liferay 5.0, JBoss 2.7, Websphere 6.1 (though you can still encounter some bugs).
Now we would like to know when the lovers of JSF will be able to profit from these features in their JSF portlets.

Are portlets dead? JSR168 and JSR286 versus reality.
Eric Spiegelberg, an experienced JEE and portlet developer, evaluates in his article JSR-286: The Edge of Irrelevance the changes brought to the portlet community by the "new" JSR 286 and comes to the sad conclusion that the portlet technology has missed its chance and is declining in interest and momentum and JSR 286 won't change that. Only rarely do the benefits of this technology outweigh the additional complexity, restricted programming model, and other drawbacks. He explains his opinions and gives reasons for them pretty well and I can only agree.
Some of the points we can make here are:

Eclipse 3.4: New Update Manager and broken Extension Locations
In Eclipse prior to 3.4 you could have a number of external "Extension Locations" for plugins/features you didn't want in the Eclipse installation directory or that you wanted to share among multiple Eclipse installations. In the Update Manager wizard you could have even selected that you want a plugin installed into a particular extension location. Since Eclipse 3.4 (Ganymede) this isn't possible anymore.
Problem 1: Links to the external Extension Locations are ignored
