Templates (re)loading...

[Jérôme BERNARD <je...@gmail.com>]

Hi,

I have a client that basically wants to be able to change the layout
of the pages generated by Tapestry.

He is usually working with DreamWeaver using the templating feature so
that he can easily change all his static pages.

He would like to be able to use those DW templates with Tapestry
pages. This could be quite easy: DW would generate the templates used
by Tapestry (for DW it would be regular files generated by its own
template). But the thing is, my client may change quite frequently the
templates (about once a week), so I need to find a way to reload the
templates "on demand" and potentially to have the templates "out of
the webapp" so that my client can FTP them (otherwise, I'll try to use
symlinks with an exploded WAR).

Any suggestion on how to do this efficently (restarting the webapp is
not an option)?

Regards,
Jérôme.

can you make a secured page that you could call the reset service from? 
Upload the new Border, then call the reset.

<component id="resetLink" type="ServiceLink">
     <binding name="service" expression="'reset'"/>
     <binding name="parameters" expression="page.pageName"/>
     <binding name="disabled" 
expression="!page.engine.isResetServiceEnabled()"/>
</component>

I don't want to include DW templates.
DW will generate the Tapestry templates.

I am in need of a kind of Border component whose template is generated
by DW and can be altered in time.

I don't think I'll be in need of such a thing.

I was thinking of another solution: instruct Tapestry to reload the
"Border" template.

Howard or Eric, any suggestion on how to do it?

Perhaps using JMX? (I activated the JMX support of Hivemind and I do
have all my page objects exported in the JMX server).

I'll keep you informed.

Re: Templates (re)loading...

[Andreas Andreou <an...@di.uoa.gr>]

How are you planning on including those DW templates in your Tapestry pages?
Do you want to allow him to also reorder Tapestry's components within a 
page?
If this is NOT the case, then you can write a border component that 
includes those static
templates (there's a component at Tassel for including static files 
within a Tapestry page, but you might want to write a simpler one yourself)
If the DW templates also contain references to Tapestry components than 
you'ld have to somehow instruct Tapestry to reload them.
You'll probably have to dig into Tap's source for how to do this, cause 
i don't really know :)
Perhaps you could extend the SpecificationResolver class (or Loader or 
somthing like that)
Also note, that if those templates reside in the WEB-INF folder the 
servlet container's classloader may not catch the changes
(there usually exists a configuration for this - but you can also store 
them in the main context path).
I'ld be interested to hear your progress on this.

This is something I can't even consider: this is a production system,
not a development one. I can't afford not to use caching of the
templates (it would be too slow otherwise).

I need to find a way to discard the cache whenever I need it.

Jérôme.

Depends; the reset service ensures that the timing is correct (at the
end of the request).

Digging through Tapestry code, I've seen that the reset service do
actually call the ResetEventCoordinator identified by service point
"tapestry.ResetEventCoordinator". Wouldn't it be simpler to call
directly the fireResetEvent() of this class?

You may use the 'reset' service.

Hi,

I have a client that basically wants to be able to change the layout
of the pages generated by Tapestry.

He is usually working with DreamWeaver using the templating feature so
that he can easily change all his static pages.

He would like to be able to use those DW templates with Tapestry
pages. This could be quite easy: DW would generate the templates used
by Tapestry (for DW it would be regular files generated by its own
template). But the thing is, my client may change quite frequently the
templates (about once a week), so I need to find a way to reload the
templates "on demand" and potentially to have the templates "out of
the webapp" so that my client can FTP them (otherwise, I'll try to use
symlinks with an exploded WAR).

Any suggestion on how to do this efficently (restarting the webapp is
not an option)?

Regards,
Jérôme.
