The try ... catch statement
The try ... catch statement is used to handle runtime exceptions.
The catch clause must specify a variable whose type is com.apama.exceptions.Exception.
You can nest try ... catch statements in an action, and you can specify multiple actions in a try block and specify a try ... catch statement in any number of actions.

} catch(Exception e) {
