[tiles] getResourceAsStream question

[Greg Reddin <gr...@fnf.com>]

I was working on some test cases for standalone Tiles and the following 
code in I18nFactorySet was not behaving as I expected:

         // If the config isn't in the servlet context, try the class 
loader
             // which allows the config files to be stored in a jar
             if (input == null) {
                 input = getClass().getResourceAsStream(filename);
             }

"input" was being returned as null in that case.  When I changed it to 
the following it worked:

         // If the config isn't in the servlet context, try the class 
loader
             // which allows the config files to be stored in a jar
             if (input == null) {
                 ClassLoader cl = this.getClass().getClassLoader();
                 input = cl.getResourceAsStream(filename);
             }

Why would it make any difference whether I reference the ClassLoader or 
not?  I noticed a couple other places where getResourceAsStream() is 
called from the class instead of the ClassLoader as well (in the Struts 
mock objects).  Is there a reason why the class is preferred?  Aren't 
they really doing the same thing?

BTW, I understand that in production that code would not likely be 
called because the config file would be returned from the servlet 
context.

For reference I'm using JDK 1.4.2 on Mac OSX 10.3.  I got the same 
results running the test target from within NetBeans 4.1 and the 
command line.  I didn't try it on Linux to see if it yielded different 
results.

Thanks,
Greg
