If
you intend to use a browser and
CICS® Transaction Gateway on the same workstation, remove ctgclient.jar
and ctgserver.jar from the CLASSPATH setting. If you do not remove them, you
are likely to receive the following error when running applications:
ERROR: java.io.IOException:
CTG6664E: Unable to load relevant class to support the tcp protocol
The
reason for the error is that
Java™ searches the CLASSPATH environment
variable before downloading classes across the network. If the required class
is local,
Java attempts to use it. However, using class files
from the local file system breaks
Java application security rules; therefore
an exception is raised.
