Error Handling (Magic xpa 3.x)
Some error handling is performed by the component. Each error is written to an error log called messaging_error.log, found in the Magic xpa root directory.
An event called Error is exposed by the component and raised as a synchronous event so that you can perform your own error handling. The parameters of the event are:
|
|
|
|
Messaging System
|
Alpha (1). The valid values are:
-
M – MSMQ
-
J – JMS
-
W – WebSphere MQ
|
|
Error Code
|
Numeric (15)
Error codes can have negative values.
There can also be other unlisted error codes from Microsoft, JMS, and WebSphere.
For a description of the Messaging Component Error Codes, see the Error Code Messages.

An event called Java Error is triggered when an error occurs while using JMS. This event has the following parameter:
|
|
|
|
JException Error
|
BLOB. This BLOB has the value returned by the JException function. When a JMS error occurs, the error string (passed by the ErrorException event) is appended with the Java Class that relates to the encountered error, which is surrounded by brackets [ ].
