A.2 Modifications to the Struts Action Class
The Struts base
Action class has been
modified with a new method called execute( ). This
new method should be called instead of the perform(
) method. The main difference between the two is that the
execute( ) method declares that it throws
java.lang.Exception, whereas the earlier
perform( ) method declared that it could throw
IOException and
ServletException. This change was necessary to
facilitate the new declarative exception-handling feature that was
added to Struts 1.1. As a result, the perform( )
method has been deprecated and should not be used in 1.1
applications. |
