Hi David,
When I am testing a class outside of the context of wo, I do it this
way:
// Properties file config
URL configURL = new URL("file:Resources/
MyFunAndExcitingLog4jConfigFileThatEveryoneWouldBeJealousOf
.properties");
PropertyConfigurator.configure(configURL);
or for xml
// XML Based config
URL configURL = new URL("file:Resources/
MyFunAndExcitingLog4jConfigFileThatEveryoneWouldBeJealousOfInBadAssXMLFormat
.xml");
DOMConfigurator.configure(configURL);
I place this code in main() because then it will not be called when
the Application uses the object, but you can also place it inside of
static { }. I imagine the same code will work in your Application
constructor.
later,
asa

I'm sure I'm missing something obvious, but
resourceManager().pathURLForResourceNamed( "Resources/log4j.xml" ,
null, null)
in my Application.java class is returning null when I run my app.
The log4j.xml is in the /Resources/ directory (in both the build and
dist directories) and flagged as a Resource. Why isn't it being
found? It seems to be an intermittent problem as it has done this
before and then suddenly started working.
I get the following NPE in Eclipse Run Log:

If I comment the following out of the Application.java file, it will
launch:
URL configURL = resourceManager().pathURLForResourceNamed("Resources/
log4j.xml", null, null );
NSLog.out .appendln("Initializing log4j from " +
configURL.toString());
DOMConfigurator.configure(configURL);
try:
resourceManager().pathURLForResourceNamed( "log4j.xml", null, null)
Thanks,
Dave
