I did a google search for "shared java hosting", to check if somebody has recorded any wonderful experience he/she has had with java hosting on a shared environment. However I could not find anything except one blog by Stefan Mischook titled "Java hosting is kicking my ass!". He concludes by saying "Java is brittle in a shared environment, hard to configure and problematic - it sucks. I think this is a symptom of the Java community’s need to over-engineer everything and shows how Java is no longer suitable for small and medium size application development."
