Description

It looks like the apache log4j plugin has been removed. If missing, I get exceptions:

java.lang.NoClassDefFoundError: org/apache/log4j/Level
at org.slf4j.LoggerFactory.getSingleton(LoggerFactory.java:189)

We need to add back the plugin.

The slf4j project is an alternative to log4j that implements method compatibility. It is a bit of fun to mix slf4j with log4j in the same project.

How was the tied in before? As as a plugin or as part of libs?

I think slf4j supplies the interfaces and you can use log4j under the hood through slf4j.

I am not able to check from here. But I think I remember that older versions of uDig have an apache.log4j plugin in the plugins folder.
