I've found in 'nix machines that some socket openings mixup the
localhost vs real IP address ethernet interfaces. The ERFA might be
listening on one, but the testcase tries to contact it on the other?
I usually confirm this by doing something like (depends on which unix
you have):
netstat -anp | fgrep LISTEN
this will show you which processes and ports have socket listeners,
and it can tell you which interface is being used. I think the
'null' parameter is saying use the 'wildcard' address, which I've
found can lead to weirdness on unix machines, particularly those that
have multiple eth interfaces. In some cases, I've had to work around
this by changing the /etc/hosts file so that 'localhost' maps to the
real IP address, and not the 127.0.0.1. Not ideal, but it does seem
to fix it.

I've been experimenting with Ubuntu 6.0.6.1 (aka Dapper Drake) as a

The same test passes on other platforms and I'm guessing that it is
a firewall issue. I've played with iptables rules (newbie at
that), but haven't fixed the problem. When I started, sudo
iptables -L showed no rules.
Build environment:
Ubuntu 6.0.6-1 desktop freshly installed in JVM
subversion and sun-java6-jdk installed in Package Manager (requires
adding multiverse to repos in Settings/Repos)
ant-1.6.5 and maven 2.0.6 installed in home directory from Apache
binaries (javah task failed in Ant when installed from Ubuntu)
export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=~/maven-2.0.6/bin:~/apache-ant-1.6.5/bin:$PATH
svn co https://svn.apache.org/repos/asf/logging/log4j/branches/v1_2-
branch log4j
cd log4j
mvn test
I was able to build an NTEventAppender.dll on Ubuntu by installing
mingw from the package manager and copying include/win32/jni_md.h
from a Windows JDK 6 to /usr/lib/java-6-sun/include/win32/
jni_md.h. Haven't actually gone back and tried the generated DLL
on Windows to make sure that it works.
