While playing around with some XMI (XML Metadata Interchange) importing/exporting functionality, I found this great blog: Modeling LAnguages (original URL https://modeling-languages.com). His service to convert from one XMI format to another is just awesome. Have a look at this site: XMI2 - A tool for exchanging UML models among CASE tools (original URL https://modeling-languages.com/content/xmi2-tool-exchanging-uml-models-among-case-tools).

Here is a nice conflict between Oracle products. I installed “Oracle Database 10g Express Edition” along with “Oracle Containers 4 Java” as the application server to run my J2EE app on. I installed the database engine first and then configured OC4J. OC4J needs an environment variable called ORACLE_HOME in order to run. This needs to point to the folder where you unzipped it. Everything worked just fine at this stage . ...

I finally managed to add this project on sourceforge … here is the link

I currently ran into an interesting issue when installing MS SQL Server 2008. During the initial checks at startup of the installation process I got the following error: “Restart required”. So I restarted my computer but without success. I got exactly the same error message again. I found out that this happens due to a wrong registry entry. In order to get the prerequisite-checks to succeed I had to delete the value of the following registry entry: ...

A couple of days ago I received an email from Steven Davis. He proposed some brilliant enhancements to the MySQL session state store provider. Thanks to him, I am able to provide a new release of it today. New features he incorporated into the provider are: added cluster db support: the ability to retry within a cluster of servers, the web.config can then use connectionStringList="," fixed timeout Minutes to TotalMinutes changed namespace to Kimpel.MySqlSessionDll to make debugging clearer Release v.03 now also supports MySQL Connector/Net 6.2. I also added a SQL script to create the necessary sessions table. ...

I really like the idea and hope to see some of it in the near future. Have a look at this video: (original URL https://vimeo.com/moogaloop.swf?clip_id=6712657&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1) 10/GUI from C. Miller on Vimeo.

I am using Microsoft’s Virtual PC quite heavily in all my development projects since it has lots of advantages in my day to day work … especially when working in multi-project environments. It is just until this week that I learned a very important lesson in this area. I can’t imagine how difficult and inefficient my setup has been. I found this very interesting blog entry “HOWTO: Use Virtual PC’s Differencing Disks to your Advantage” by Andrew Connell that makes life so much easier and in additon to that saves tons of space on my harddrive.

I just ran into an interesting exception within a Java project. I implemented a couple of Java classes along with hibernate mapping files. Until today, everything worked just fine. I then added some attributes/properties to a class and completed the mapping file. After deploying and testing the application I ran into the following hibernate exception: org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer] I really couldn’t figure out what was wrong and tried almost everything. I just overlooked a little tiny detail: I misspelled a getter-method in the Java class and this led to the exception above. ...

I am totally excited about my new home entertainment system. It uses a standard digital satellite dish along with an external FireDTV (Digital Everywhere) digital TV receiver connected to my more or less frumpy desktop PC. The computer runs Windows 7 RC with Media Center configured to use the satellite box. My living room is equipped with a Xbox 360 connected to the TV. The Xbox 360 and my desktop PC talk to each other via powerline AV ethernet connection (since I totally forgot to put a system of conduits in my home). ...
