public final class ExceptionHelper
extends org.mule.runtime.api.exception.ExceptionHelper

ExceptionHelper provides a number of helper functions that can be useful for dealing with Mule exceptions. This class has 3 core functions -

1. ErrorCode lookup. A corresponding Mule error code can be found using for a given Mule exception 2. Additional Error information such as Java doc url for a given exception can be resolved using this class 3. Error code mappings can be looked up by providing the the protocol to map to and the Mule exception.

Method Detail

getErrorCode

public static int getErrorCode(Class exception)

getErrorCodePropertyName

public static String getErrorCodePropertyName(String protocol,
                                              MuleContext muleContext)

getErrorMapping

public static String getErrorMapping(String protocol,
                                     Class exception,
                                     MuleContext muleContext)

Maps an exception thrown for a certain protocol to an error. When there's no specific error for such transport it will return a generic error. Most likely the returned error is an integer code.

Parameters:

protocol - scheme for the transport

exception - exception mapped to error

muleContext - the application context

Returns:

the error for exception for the specific protocol

getTransportErrorMapping

public static String getTransportErrorMapping(String protocol,
                                              Class exception,
                                              MuleContext muleContext)

Maps an exception thrown for a certain protocol to an error. Most likely the returned error is an integer code.

Parameters:

protocol - scheme for the transport

exception - exception mapped to error

muleContext - the application context

Returns:

the error for exception for the specific protocol
