Build error?

Hi all.

I'm noticing a strange problem: fop builds correctly, but then it seems it 
is not working at all.

I'm using it from the command line under win xp, and even if I don't get 
any run time exception no output file is created. Launching fop with no 
parameters, or with wrong parameters (missing files ...) does not create 
any error: simply, nothing happens.

I have compiled fop on two different computers, so I don't think this 
is a local configuration problem.

Hasn't anyone else noticed this?

Regards
     Luca

I've commented out the offending code. I don't really know what to do
with it. It would probably be cleanest if the cli package wrote to the
console using System.out/err only and only sets up the logger for the
rest of FOP. Hmmm.

Luca,

not sure if this is it but in CommandLineOptions we have:

if (System.getProperty("org.apache.commons.logging.Log") == null) {
     logFactory.setAttribute("org.apache.commons.logging.Log",
                                 CommandLineLogger.class.getName());
       setLogLevel("info");
}
log = LogFactory.getLog("FOP");

i.e. the log instance is created after the call to setLogLevel(...). But 
setLogLevel starts with:
...
if (log instanceof CommandLineLogger) {

so you are hitting a likely NPE here.
