Re: Upgrading Struts from 1 to 2.0.14
Wes Obama -- You will make a fine Struts Czar once your publication is released. Please consider me for a cabinet position -- Newton can be my driver. Peace, Scott Struts 1 is well-supported, and saw a new release just about a month ago. So, it is supported and maintained. Struts 2 is a rewritten next generation of Struts. If you are looking to get an existing project up-to-date, just grab the latest Struts 1 release (if memory serves, it is 1.3.10). If you are looking to move into a build an app from scratch, and want to use a modern framework (yet quite a bit different from Struts 1), then look at Struts 2. If you are considering the differences between the two, there is also a good set of migration docs available here - http://struts.apache.org/2.0.14/docs/migration-guide.html There is also a Struts 1 / Struts 2 plugin, but depending on your reasons for upgrading, I'm not sure that this is the route you want to take. -Wes - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org -- View this message in context: http://www.nabble.com/Upgrading-Struts-from-1-to-2.0.14-tp21443421p21486320.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

RE: Upgrading Struts from 1 to 2.0.14
I second that point. We did same thing and only ported parts of S1 code when needed but the two run in parallel and interact beautifully. And the neat thing is we can use the dojo widgets from S2 in S1 pages. Not as is as in S2 but not very complex. -- Radu Solomon Software Developer N-able Technologies(r) 450 March Road, 4th Floor Ottawa, Ontario K2K 3K2 www.n-able.com rsolo...@n-able.com Tel: (613) 592-6676 x 301 Toll Free: 877-655-4689 x 301 Fax: (613) 592-2242 -Original Message- From: Robert Graf-Waczenski [mailto:r...@lsoft.com] Sent: January 14, 2009 3:06 AM To: Struts Users Mailing List Subject: Re: Upgrading Struts from 1 to 2.0.14 Frank W.

Thanks Dave for the reply. I did not follow any process. I just wanted to upgrade Struts from1 to 2.0.14. SO read at the user guide that you just need to throw the *.jar files to your lib(http://struts.apache.org/1.x/userGuide/installation.html#Prerequisites). Thats all I did.

Re-write? So if someone wants to upgrade struts, they have to be prepared to re-write their application in new version ..if thats the case then I think its the last thing a developer will do. If I have re-write the application, I would rather look at some much better frameworks, like spring-Hibernate/JSF. newton.dave wrote: SanJ.SANJAY wrote: Thanks Dave for the reply.

Agreed; there needs to be a valid business need to re-write an application in a new framework. This is true no matter what. If I have re-write the application, I would rather look at some much better frameworks, like spring-Hibernate/JSF. Better is, of course, *highly* subjective. You'd have to *really* work to convince me that, say, JSF is (a) better than S2, and (b) an easier re-write (than to S2) from S1 (hint: it isn't).

You could always go with door #3: don't upgrade at all. S1 is still a perfectly viable framework, and especially if you have no pressing need (other than resume padding), then what's the point of upgrading at all? There are TONS of perfectly good applications still in the wild running on S1, and no one is clamoring to update many of them. Dave is 100% correct: S2 != S1.
