Re: java.rmi.RemoteException: EJB Exception:nested exception is: java.lang.java.lang.NoClassDefFoundError

Murali,

a NoClassDefFoundError occurs, when a class is present in the classloader=
,
but there was some problem loading the class. This can be a static
initializer that throws a runtime exception, a wrong classloader (there
are a lot of different classloaders in an EJB environment), or a lot of
other reasons. Have a look that all the JARs are in their proper places
(it's not enough, if they are in some classpath), make a static
initializer failsafe (always, or at least decent logging) - and if all
doen't help, try to explain the problem here in more detail (is SAPIAgent
part of an external JAR, ...).

Kind regards,

Andreas Berg
