Not directly, but people were using Tiles 1 with WebWork 2 before
Tiles 2 existed.

I expect the same technique Matt used with T1 and WW2 could be used to
use T1 with S2.

Re: Struts2 and Struts1 comingling w/ Tiles

[Ray Clough]

I use S1 with T1 using the standard tiles-defs.xml definition file.  I use S2 
with T2 using tiles.xml file.  It is true that if your jsp pages include the 
Tiles tags, then you would need probably need separate versions for T1 and T2.  
I generally only use Tiles in the Template file, and I do have 2 of them.  That 
is a very simple file, though, and duplicating it is easy.  If I feel the need 
for Tiles tags in the component jsp's, then I'd have to duplicate them also, 
which would definitely be a pain. 

Calling S1 actions from S2 or S2 from S1 just requires putting ".do" after the 
action (from S2) or ".action" (from S1).  I typically use the S2 tags in my new 
pages, and they work OK called from S1 actions.  I mostly use links, rather than 
buttons.  I have found that some fudging is necessary:


calling S2 action using S2 tags (use 'action' attribute):

   
   
   
   

calling S1 action using S2 tags (use 'value' attribute)

   
   
   
   

I have also used the jstl core tags for the url, but you need to put the suffix 
after the url.


calling S2 from S1, using S1 and jstl tags:

 
 
 
  key="rp.Xxxx" bundle="menu" />
   
calling S1 usign S1 tags:


 key="rp.Xxxx"

   bundle="menu" />

I hope this helps.

Ray,

Which definition files specifically do you need to be split?

One of the biggest problems I had (which I couldn't figure out) was mixing
jsps with T1 and T2. At compile time, all my JSPs wanted to be either
T1-compliant, or T2-compliant.

Even if I had figured this out, there is still a big problem because you
can't migrate some actions to S2 without duplicating jsps to be in T2 mode
because S1 actoins and S2 actions may be using those jsps simultaneously.
Which means a messy migration with a lot of (jsp) code replication.

I still stand firm -- until there is S1->T2 compatibility, migrating from
S1->S2 will be a nightmare, if Tiles are involved.

I also suspect that calling S2 actions from S1 would have to be hard-wired
with , as opposed to using html:link. Is that so?

I know Antonio has worked on T2 support for S1, but I don't think it's quite
ready yet

Your saying that any S1 app using Tiles can't, based on your experience, 
be run with part of it being S2-based, in the same WAR?  Could you 
describe more what the problems you encountered were?  I was considering 
doing this for one app I have, the only one I've ever used Tiles in 
actually, and it would be really nice to know what you found, since I 
don't think it's an especially unique or special thing to think about doing.

It is a futile excercise which cost me 24 man-hours.

The best approach would be to do a complete port of your app to S2 and T2!
