Slightly OT: loading resources in a Tapestry application
I have a package that has to read a few files before it can do any
work. In a previous, non-Tapestry incarnation, I put these files in the
top directory of my web context, which I just pointed Tomcat toward on
my development machine.
With Tapestry, I'm warring everything up and installing it using the
Tomcat manager.
Here's my problem: I've tried sticking the files everywhere, I've tried
using every ClassLoader.getSystemResourceAsStream() permutation I could
think of, and things just don't seem to be working. When I run JUnit
tests, the files get loaded, but I copy them elsewhere and run them in
Tomcat, and no dice.
Suppose one of my files were "xyz.pwi". Where would you put that in the
file system, and how would you load it once the code is all copied into
Tomcat?
TIA,
Todd

I subclassed BaseEngine and put the below stuff for a createGlobal() method.
The rest of my engine class is empty, so it's not a big deal. WebApplication
is my own class, of course.
protected Object createGlobal(RequestContext context) {
WebApplication global = null;
try {
global = (WebApplication) super.createGlobal(context);
}
catch (ClassCastException e) {
throw new ElevanceError("Unable to cast Global object into a
WebApplication instance", e);
}
String configFileName =
getPropertySource().getPropertyValue("se.elevance.timer.config-file");
global.initialise(context.createSession().getServletContext(),
configFileName);
return global;
}

Is there an alternate way of doing this? I don't have my own Engine,
and I'd prefer not having to think about that if possible.
Alternatively, can I subclass the default Engine class and just put
this in createGlobal() or are there any gotchas that I also have to
take care of in createGlobal()?
Thanks,
Todd

WEB-INF/classes should be included on your classpath. With Tomcat, I am able
to read files from that location using ServletContext.getResourceAsStream().
I would think that using the ClassLoader is maybe a little less sure to
work. To get the ServletContext, I do a
RequestContext.createSession().getServletContext() in my engine's
createGlobal() method.
