Class UserError

java.lang.Object

java.lang.Throwable

org.glassfish.appclient.client.acc.UserError

All Implemented Interfaces:

Serializable

public class UserError
extends Throwable

Represents any user error, such as an invalid combination of command options, or specifying a non-existent JAR file.

Such errors should be user-correctable, provided the message is clear. So no stack traces should be displayed when UserErrors are thrown.

Method Detail

formatUserError

public static UserError formatUserError(String message,
                                        String... args)

Creates a new UserError instance having formatted the message with the arguments provided.

Parameters:

message - the message string, presumably containing argument placeholders

args - 0 or more arguments for substitution for the placeholders in the message string

Returns:

new UserError with message formatted as requested

setUsage

public void setUsage(String usage)

Sets whether or not the usage message should be displayed after the error message is displayed to the user.

Parameters:

showUsage - the new setting

displayAndExit

public void displayAndExit()

Displays the user error message, and any messages along the exception chain, if any, and then exits. If showUsage has been set to true, then the usage message is displayed before exiting.

Only the messages, and not the stack traces, are shown because these are user errors that should be user-correctable. Stack traces are too alarming and of minimal use to the user as he or she tries to understand and fix the error.
