Re: [aspectj-users] Exception inthread"main"java.lang.NoClassDefFoundErr

Robert,

I saw that the error originates from commons-logging. I remember vaguely 
that Websphere has a bundled version of commons-logging - is that true? It 
might be the case that the container's class loading of clogging conflicts 
with LTW's idea of a class hierarchy. Try to switch to parent-last 
classloading or alternatively replace the container's commons-logging with 
slf4j (you'll need jcl-over-slf for the clogging interfaces, slf4j-api for 
the slf4j interfaces and slf4j-log4j for the backend). The jcl-over-slf 
intrefaces are binary-compatible with clogging but the implementation 
exhibts less "dynamic" (read: often failing) behaviour at runtime.
