good to hear that's working! Would really appreciate further feedback
on what works/doesn't etc as we get closer to a release.
cheers,

Actually here's the 'official' 1.0 jar published in the Maven Central
repository:
http://repo1.maven.org/maven2/jmdns/jmdns/1.0/jmdns-1.0.jar
Try that one, I'll keep looking at 2.0 (they don't call me the
upgrade-
a-tron for nothing).

Very simple and straight forward.
However, as soon as I run the app, I get the following Error:
java.lang.InstantiationError: javax.jmdns.JmDNS

org.apache.log4j.net.Zeroconf4log4j.<clinit>(Zeroconf4log4j.java:23)

.log4j.net.ZeroConfSocketHubAppender.activateOptions(ZeroConfS
ocketHubAppender.java:45)
Looking at the javadoc for that Error:
* Thrown when an application tries to use the Java <code>new</code>
* construct to instantiate an abstract class or an interface.
* <p>
* Normally, this error is caught by the compiler; this error can
* only occur at run time if the definition of a class has
* incompatibly changed.
My guess is that you have an incorrect version of the JmDNS library
in your classpath. Which version of jmdns are you using?
log4j-zeroconf requires:
[INFO] [dependency:tree]
[INFO] log4j:apache-log4j-zeroconf:jar:1.0-SNAPSHOT
[INFO] +- junit:junit:jar:3.8.1:test
[INFO] +- log4j:log4j:jar:1.2.16-SNAPSHOT:compile
[INFO] \- jmdns:jmdns:jar:1.0:compile
I now notice that JmDns has a 2.0 available, which is probably the
issue here. Could you download 1.0 and replace it (looking at
sourceforge, they don't appear to publish older jars, weird, if you
like I can send you the jmdns 1.0 jar in a separate, direct
email)? I
'll go and play with JmDNS 2.0 to test compatibility with that.
Since log4j-zeroconf is not a released product yet, if 2.0 looks the
goods, I'll mark log4j-zeroconf to depend on that.
