The <c:catch> tag catches any Throwable that occurs in its body and optionally exposes it. Simply it is used for error handling and to deal more gracefully with the problem.
The <c:catch> tag has following attributes:
Attribute | Description | Required | Default |
---|---|---|---|
var | The name of the variable to hold the java.lang.Throwable if thrown by elements in the body. | No | None |
