A Client Error Messages
This appendix describes the pop-up messages that end users can receive while
running a Pathway/iTS web client.
General Information
Messages with numbers in the range 3000 through 3299 are analogous to the
corresponding, same-numbered terminal control process (TCP) messages issued
when screen programs are running on the NonStop system. These messages are
generated by the Pathway/iTS gateway threads and passed to the Java applet portion
of the web client.
Messages with numbers 3300 and higher are specific to web clients and are generated
by the Java applet.
All client messages include a stack trace, indicated by the
error-loc
variable
following the message text. For some messages, this stack trace contains additional
information about the location of the error within the Java code. The text in a displayed
message with stack trace appears as in this example:
pathway.its.ScobolException: Error 3015: Arithmetic Overflow
at pathway/its/Pic9.<init>
at pathway/its/Pic9.<init>
at ITSDEMO1.<init>
at SCThread.run
Message Descriptions
The following pages give displayed message text, cause, effect, and recovery
information about each client error message.
3002
Cause. A DEPENDING ON data item was larger than the limit specified in the
OCCURS clause.
Effect. The applet stops.
Recovery. Isolate and correct the problem within the Java program, using the stack
trace information in
error-loc
to locate the problem. Alternatively, correct the
problem in the SCREEN COBOL program and reconvert the application.
