log4j

[rolf_schumacher]

java exeption:
log4j:ERROR Could not find [log4j.dtd].
...
org.xml.sax.SAXParseException: Relative URI "log4j.dtd"; can not be resolved without a base URI.

copied jboss 3.0.6 to a debian directory and ran ./run.sh.

Question:
Why there is no log4j.dtd in the whole distribution?
How to overcome this?

There is another error in the output:

What might have caused this? How to go on?

By the way, the log4j error appeared in the error output without a timestamp. The null pointer exception apeared in the standard output. I'm not able to correlate this. I tried to get informed what other logging might help, but I feel I have to bring up log4j first.
