<DL>
<DD>Constructs a new servlet exception when the servlet
needs to throw an exception and include a message
about the "root cause" exception that interfered with its
normal operation. The exception's message is based on the localized
message of the underlying exception.
<p>This method calls the <code>getLocalizedMessage</code> method
on the <code>Throwable</code> exception to get a localized exception
message. When subclassing <code>ServletException</code>,
this method can be overridden to create an exception message
designed for a specific locale.

that interfered with the servlet's
normal operation, making the servlet exception
