public static void rethrowBLException(java.lang.Throwable t,
                                      java.lang.String message)
                               throws BLException

Takes a throwable and rethrows it wrapping it into a BLException if necessary. It wraps the throwable into a BLException if it is not already an instance of BLException, nor RuntimeException and nor Error, in which case it rethrows the throwable as it is.

Parameters:

t - the throwable.

message - error message to set in the BLException if the original throwable needs to be wrapped.

Throws:

BLException - if the throwable is not a RuntimeException nor Error. If the throwable is already an instance of BLException the exception thrown by this method is exactly the same instance.

                                           java.lang.String message)
                                    throws javax.servlet.ServletException,
                                           java.io.IOException

Takes a throwable and rethrows it wrapping it into a ServletException if necessary. It wraps the throwable into a ServletException if it is not already an instance of ServletException, nor IOException, nor RuntimeException and nor Error, in which case it rethrows the throwable as it is.

Parameters:

t - the throwable.

message - error message to set in the ServletException if the original throwable needs to be wrapped.

Throws:

javax.servlet.ServletException - if the throwable is not a RuntimeException, nor Error, nor IOException. If the throwable is already an instance of ServletException the exception thrown by this method is exactly the same instance.

java.io.IOException - if the throwable is a IOException instance already.
