Looking for instructions on migrating from Struts 1.0.2 to 1.2.7

[pa...@firstenergycorp.com]

Hello,

Can anyone point me to some documentation that helps you migrate Struts
apps from version 1.0.2 to 1.2.7?

Thanks in advance for any help.

Re: Question about ActionForward.setRedirect method

["Frank W. Zammetti" <fz...@omnytex.com>]

I have to make some educated guesses here, because I don't know the full
Struts lineage at that early stage (didn't start using it until 1.1)...

The message your seeing is because the forward configs are frozen once
they are read in.  Recall that, like Actions, there is one instance for
any given forward config and this is shared by all requests.  If you could
alter them in one request, you could adversely affect another.

My *guess* is that the configuration freezing was added after 1.0.2.  I
don't know that for sure though.  In any case, it is certainly the case in
1.2.7.

The way to deal with this is to return an ActionRedirect from your Action
instead.  One of the constructors for that class takes in a ForwardConfig,
so what you can do is:

ForwardConfig f = new ActionRedirect(mapping.findForward("whatever"));
f.setRedirect(true);
return f;

Alternatively, you could just have new mappings in struts-config that are
defined as redirects, so you could just remove that setRedirect() call
entirely.

Question about ActionForward.setRedirect method

[pa...@firstenergycorp.com]

Hello,

I'm converting my struts apps from version 1.0.2 to 1.2.7.

In my 1.0.2 app I can call ActionForward.setRedirect method and pass it
"true" with no problem. When running with 1.2.7 it generates the following
error.

   Error [javax.servlet.ServletException: Configuration is frozen], with
   root cause [java.lang.IllegalStateException: Configuration is frozen].


Can someone please explain why?

Thanks!


David

Unfortunately, I don't think anyone has contributed anything on upgrading 
from Struts 1.0 yet:
   http://wiki.apache.org/struts/StrutsUpgrade

Your best bet is to review the release notes for each version in between the 
two you're working with.  Start here and work backwards using the links in 
the first line of each page:
   http://struts.apache.org/struts-core/userGuide/release-notes.html

A useful exercise might be to take an example app from 1.0.2 and convert it 
to 1.2.7.  Then post your notes on the Wiki. :)
