We try to change the JDK version for a graphical Java Web application (based
on ILOG JViews framework).
Everry thing used to work fine on JDK 1.3.1 but when we run on JDK 1.4.2 we
have a NoClassDefFoundError.

Server is Sun Solaris,
Application Server is Sun iPlanet 6.0.5.

class sun/io/ByteToCharEUC_KR is normaly hosted by charsets.jar and the file
is in the JDK.

Exception from log file:
 [09/Feb/2006:19:45:54] failure (14742): Internal error: servlet service
