Method Detail

getPropertyHelper

public static compbio.util.PropertyHelper getPropertyHelper()

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. pros: cons: only classes and lib/*.jar are added, Eclipse will remove non classses from classes dir. Try 1 - succeed.
