Help On Migration
Hi All,
I am migrating an existing FrameWork(classes which are extending from some
of the Struts classes like FormTag,TextTag etc) from struts 1 to struts 2.
It uses MessageResources. I found out that the replacement for the same in
struts2 (2.0.11)is WrapperMessageResources which extends from the
MessageResources.
But to use the WrapperMessageRessource I need to use the struts
1.3.5-core.jar provided along with the struts 2.0.11 release otherwise I get
a compilation error as "MessageResources class not found. It is used
indirectly by one of the class files". So is it proper to use the struts
1.3.5-core.jar? If not Pls suggest a replacement for MessageResources.
Thanks,
Sandeep

Hi Laurie,
I understand what you are trying to say. What I exactly have is a set of
classes which extend from the FormTag, TextTag, ActionError and ActionErrors
and do some business Logic implementation. Here They have used the
MessageResource for holding the error messages. Now I need to do the same
thing in struts 2. When I saw the javadoc it said the WrapperMessageResource
was a wrapper over the struts1 MessageResource in struts2 and the
WrapperMessageResource extends from the MessageResource.
Also I need to migrate classes which are extending from ActionError and
ActionErrors and have the business Logic implemented. I know that struts-2
is not providing ActionErrors nor the ActionError. Instead in the
application we have to use addActionError() method provided by the
ActionSupport class if I am right. It's easy to do this in an application
migration. But I am wondering how to migrate the classes in the framework to
struts-2.
Looking Forward For ur help.
Thanks,
Sandeep

As Antonio told you, it isn't really a question of 'replacements'.
Although conceptually similar, Struts 1 and Struts 2 are entirely
different codebases. You should think in terms of what you need to
achieve in Struts 2, not in terms of what APIs you used to achive
something similar in Struts 1.
That said, I have no idea what WrapperMessageResources is. It's not part
of the Struts 1, Struts 2 or XWork APIs as far as I can tell. You
certainly don't need to include Struts 1 jars in a Struts 2 application
to access message resources though.
If you can explain what it is you are trying to achieve we may be able
to offer better guidance.
