uimaj-ep-runtime includes uimaj-core. This project includes the
Log4jLogger_impl class, which imports "org.apache.log4j. ... " package.
I updated the uimaj-ep-runtime plugin so that it "imports" this
package. However, that didn't quite work - Eclipse said it could not
find any bundle that exported that package.
I fixed that (workaround) by going to
http://download.eclipse.org/tools/orbit/downloads/drops/S20080209163815/
and dlownloading org.apache.log4j_1.2.8. That allows now, the
uimaj-ep-runtime to compile.
I would prefer some mechanism for log4j support which didn't require it
to be present.
Maybe there is a way to specify this in the OSGi manifest....
