Just a guess:

servlet engines load classes in the following way:

- classes in CLASSPATH or global lib (tomcat/lib in tomcat) are loaded 
through application classloader
- classes in different webapps are loaded through different classloaders 
each.

In tomcat, if you have a common jar to several webapps, you can put it 
under lib. I guess that in catalina that no loger works, because of 
security concerns, so you should move or copy (probably) ecs.jar from 
tomcat/lib to webapps/jetspeed/WEB-INF/lib

If it is not this one, look for jars in tomcat/lib that are needed and 
absent in jetspeed.jar, and move them or copy them to tomcat.

Good luck! :)
