Apptivity and " received unknown message type " Java error
If in a deployed setting an Apptivity applet runs into the error
"received unknown message type" (displayed in the Java console),
make sure that the Apptivity classes used by the deployed applet
match exactly those used for development.
For example, if you have applied a patch to Apptivity and rebuilt
the applet with that patch before deploying the applet, make sure
that the Apptivity classes deployed to the server are the same
as the development classes (i.e. that the same patch is applied to
the server).
This is just one possible cause of the error "received unknown message
type" as seen in the Java console at runtime.
The following is a sample of what will be seen in the Java console
(this was taken from a Netscape 4.0 Java console with debug level 9;
to get this level of debugging, type the number 9 in the Java console
when it is displayed):
# Loading class progress.apptivity.client.abColValue
# Fetching
http://biv_oracle1/Apptivity/Crusoe/progress/apptivity/client/abColVal
ue.class
received unknown message type
Once you have insured that the Apptivity classes on the server are
in sync with those used for development, restart Apptivity server
and restart the client browser before loading the applet URL to see
if the error goes away.
