Subject Re: loading properties file from WEB-INF instead of WEB-INF/classes
Date Mon, 19 Apr 2010 18:02:21 GMT
props file can be placed in src package and then placed along with classes 
in the Web-INF directory when compiling with the destination flag .This 
method has been used since jdk 1 for internationalization and is understood 
by new and old devs. On a side not perhaps someone can help me with a 
related question regarding how we intwenationalize images? or a link:P
