Last night I migrated the oostpoort website from Drupal 5.x to Drupal 6.x. The following steps did i executed to successful migrate the website.

1. Downloaded for each used 5.x module the 6.x release.
2. Make first backup.
3. Upgrade Drupal 5.20 to latest available level 5.22.
4. Upgrade all used Drupal 5.x modules to latest available level.
5. Make second backup.
6. Disable all none core related modules
7. Uninstall update_status 5.x module
8. Remove all Drupal 5.x modules from file system
9. Remove Drupal 5.x core files from file system.
10. Install Drupal 6.x core on file system
11. Configure settings.php (Take the new 6.x template as base) with correct database settings. Set $update_free_access to TRUE.
12. Access the website.
13. Run update.php two times
14. Now the system runs without any issues on Drupal 6.x
15. Install all needed Drupal 6.x modules.
16. Enable all modules and run again update.php
17. Change $update_free_access to FALSE in settings.php
18. Optional: Update theme template

QtCreator 1.3.81 not stable

wplaat — Wed, 24 Mar 2010 03:35:37 +0000

Hi everybody, Some days ago i have upgraded QtCreator (Windows release) from 1.3.1 to 1.3.81 (2.0.0 alpha). This release is not stable with a SubVersion Qt project. Problem is that with or without a Windows subversion client installed (Tigris.org SubVersion client v1.5.8) QtCreator is crashing during the indexing of the Qt SVN project. When I remove all .svn directories out of my Qt project QtCreator is running fine. So what could be wrong? Looking forward to a fix for this critical issue?

My bug report send to the Qt

P.S. With QtCreator 1.3.1 with trigris.org SubVersion plugin is working fine!

JasperReports basic example

wplaat — Thu, 11 Mar 2010 19:00:46 +0000

Hi everybody,

Today i have played around with JasperReports. Really nice java tool to created very easy reports. I did not find many examples on internet. Therefor I post my first try. I hope this will help other developers starting up with this great tool.

This example runs a query (JDBC connected) with some parameters define in Java. The result is converted to PDF and then zipped.
