i18n resources-file, problem isolated !

[Markus Blaurock <bl...@dig.de>]

Heyaho, the problem is isolated!

Reproducable with the struts-example
and tomcat 3.1 under Linux jdk, 1.2.2 from Sun.

The directories are the problem:

if you put the *.properties file directly
below WEB-INF/classes, and say in your
web.xml file 
      <param-name>application</param-name>
      <param-value>ApplicationResources</param-value>

(leaving off the org.xxx.xxx.xxx part)

then you get 2 phenomenons:

1. struts doesn't find the file anymore..
2. the output when starting tomcat ist shorter.
   Stuts doesn't print any debugging info..

Now i think this isn't a struts problem anymore.
Anyone from tomcat-dev reading this ?

That is correct.  Tomcat, and other servlet containers that implement 2.2, will
define a special class loader for each web application, which (among other
things) loads classes (and resources) from the WEB-INF/classes and WEB-INF/lib
directories for that web application.  If you are curious, you can look at the
Javadocs for "java.lang.ClassLoader" to see what a class loader has to be able
to do.

I can tell you from experience (my "day job" at Sun is working on Tomcat) that
getting resource loading in a class loader to work correctly is pretty
intricate.  I'm still investigating this problem area, but don't have a general
solution to offer yet.  One thing that makes this interesting to figure out is
that the current Struts code works fine for me on two platforms (Windows98+Sun
JDK 1.2.2_05 and RedHat 6.1 + Sun JDK 1.2.2-L), using either the standard
Tomcat 3.1 release or the most current stuff from the CVS repository.  It's
harder to debug problems when you can't reproduce them :-(.

That is, AFAIK, because there are different Class Loaders for classpath and
for each context.
Am I right?

forget everything, please.

the problem is another one:
I had struts.jar in my classpath
when starting tomcat  !  (blaeh) :-(

I don't know why, but it seems
the properties file will get loaded
from the same 'area' where the 
class comes from, which does the ResourceBundle.getBundle
call.

sorry.
