Start from scratch – Java

Time to get hands dirty in Java mud

Lots of projects here are Java based, plus something like Struts, Spring, Hibernate, etc. I don’ t like the structure much but I have to understand how to get things done, or at least I need to be able to read those codes and configurations (I hate so many configuration files in Java world).

I was trying to setup Eclipse with Struts2 and Tomcat, I was so amazed by memory management in Java VM, want to know my impression? In one world, MESS. After dealing with this and that kind of all sort of “MaxXXXSize” configuration directives (or command line parameters), I finally figured out “-XX:MaxNewSize=128m” and “-XX:MaxPermSize=128m” are two of the most important parameter to make Eclipse stop reporting “PermGen Space” error.

Thinking of setting up such an IDE really takes time, I was thinking maybe I should go back to my vim time …

BTW, people here developing software on local machine (I mean desktop), Java is cute in this case – write once and run everywhere.
