The need for a framework like PCE stems from the recurring task of having to manage, persist, retrieve and display products (or for that matter entities that can be viewed as products) of … Continue reading New open source project: Product Catalogue Engine

When running Tomcat with Eclipse, the web application may restart even for the most trivial changes incurring long pauses. I found the following settings for Tomcat to minimize restarts … Continue reading Tomcat, Eclipse, Spring and reloading

For those of us living and working outside the 7bit-speaking ANSI niche there is one webserver setting to verify: the … Continue reading Non-Latin characters, openID and the openid4java library
