Dear fellow monks,

I am currently trying to integrate some Java into a perl program and I seem to be stuck. This is the relevant part of my code:

    
BEGIN {        
   $ENV{CLASSPATH} .= ":log4j.properties:log4j-1.2.14.jar:myclass.jar"
+;
   $ENV{EXTRA_JAVA_ARGS} = "-Dlog4j.debug";
}

use Inline Java  => 'STUDY',
               STUDY => ['mypackage.myclass','org.apache.log4j.Logger'
+],
               AUTOSTUDY => 1;

As you can see, the Java code I am trying to integrate uses log4j and that seems to be the problem, because when I run this code I get the following warnings:

log4j:WARN No appenders could be found for logger (xxx.yyy.DBConnection).
log4j:WARN Please initialize the log4j system properly.

After googling this message, I found this, where it says:

The reason why you see this message is that your log4j configuration file(i.e. log4j.xml or log4j.properties) is NOT found in the classpath.

But I have a log4j.properties in the same folder as my script and the jars I use. As you can see from the code snippet above, i tried to explicitly add the properties file to the classpath. I also tried to switch on log4j debugging via EXTRA_JAVA_ARGS, but nothing has helped me to get rid of the warnings.

I use perl 5.8.7 on SuSE Linux 10.0 and Inline::Java 0.52.

Any help would be greatly appreciated.
