Hi Jeff- from my experience ClassNot FoundException can happen when 1)the class is not found by any of the CL's on any CLASSPATH *not physically there* 2)You've come upon the dreaded class signature change e.g. void fu(bar) becomes bar fu(bar) OR void fu(void) becomes void fu(bar)
from my experience there is no easy way to remedy this without rebuilding..I would suggest on a fresh disk install and config the target JDK/JVM/JRE re-install JBOSS (to use the new JDK/JVM/JRE) recompile and or rebuild all dependent projects (using target JDK/JVM/JRE) re-deploy the newly built dependent jars to JBOSS logging/commond-digester/XML-parses using target JDK/JVM/JRE..(leave no stone unturned) recompile/rebuild your webapp using target JDK/JVM/JRE re-deploy the newly built war/ear webapp to JBOSS In DI (dependecy injection) scenarios I've seen this happen when a factory builds new (bean) classes but the Factory doesnt have the correct template (usually XSL template) for the target JDK/JVM/JRE maybe the TC developers want to weigh in....
