Subject Re: classloader during tomcat startup
Date Tue, 18 Oct 2005 07:04:25 GMT
I don't know from the details of tomcat implementation, but i'll response
using common sense and from my experience.

Tomcat loads all .jar descriptor at webapp startup so it know which .jar
contains
which class. But it does not load the .class binary content;
Each time a class is required, a Class is request to classloader by jvm.
If this is first time classloader has to return the Class, it initialize it.

So static block is run at first time class is requested.

This is common sense as it prevents initialising classes you never use
in your library.
