I've very successfully used log4j-1.2.12 as a plugin within Eclipse RCP
applications.
Now I've written a simple new FileAppender that has the time and date in
it's file name.
I've compiled that into a jar which I've made into an separate Eclipse
plugin.
However when I run an Eclipse RCP which has the original log4j plugin and my
new extension plugin when I configure log4j via a properties file my new
Appender class is not found and I get the ClassNotFoundException listed
below.
The RCP application can see the right classes because I can programmatically
create my new Appender class.
Any ideas very gratefully received.
