Messages
When we use the Liberty profile, we might encounter system messages. Each message has a unique message identifier, and includes an explanation of the problem, and details of any action that we can take to resolve the problem.
Liberty profile system messages are logged from various sources, including application server components and applications. For the Liberty profile, the message identifier is 10 characters in length and has the following form:
- CWXXX9999X
where:
- CWXXX
- Is a five-character alphabetic message prefix that identifies the Liberty profile component.
- 9999
- Is a four-character numeric identifier used to identify the specific message for that component.
- X
- Is an optional alphabetic indicator that identifies the message type: I=Informational, W=Warning, E=Error.
The Troubleshooter reference: Messages topic contains information about all WebSphere Application Server messages, indexed by message prefix. For each message there is an explanation of the problem, and details of any action that we can take to resolve the problem.
