Ways to fix path problem: 1) find a path to WEB-INF directory based on
+ the path to a known class. Then prepend this absolute path to the rest of
+ paths pros: no input from user cons: relocation of the source may cause
+ problems 2) Require users to add configuration directories to the class
+ path and then load entries from it. pros: cons: Many paths needs to be
+ added. Put significant burden on the user. Hard to tell web appl server
+ to add these entries to its class path. 3) Ask for project source
+ directory explicitly in the configuration. pros cons: similar to 1, but
+ this initial configuration file must reside in well known location! Why
+ ask users what can be found automatically? 4) Have everything in the
+ location already in class path for tomcat. cons: only classes and
+ lib/*.jar are added, eclipse will remove non classses from classes dir.
+
+ Try 1 - succeed.

Method return the absolute path to the project root directory. It assumes
