Best Practices to Customize Struts-Config and its DTD

Hi

I need to add some complex XML elements in the struts-config.xml
and I'm looking for the best way to do it.

My needs are :

1- add custom xml elements inside <action> elements.
2- be able to validate the struts-config.xml document. (I'd prefer not to disable the 'validating' param in web.xml)
3- as I will need to customize the DTD, how can I remain compliant with future releases of the Struts' DTD ? Is it possible to play with namespaces to achieve a good separation between my tags and Struts' tags ? would it be better to use XSD than DTD ?

thanks for advices and ideas :)

ps: sample xml code:

<action-mappings type="sample.MyActionMapping">

	<action>
		<myTag val1="xxx" val2="xxx"/>
		<forward name="xxx" path="xxx"/>
	</action>

</action-mappings>

ps: I've already tested the digester side (adding a param 'rulesets' in web.xml)

Why not
<action className="MyExtendedMapping"     path="...">
     <set-property  property="config" value="some_config_file.xml"/>
     <forward name="xxx" path="xxx"/>
</action>

That way you can write your own dtd and stay struts-compliant.

Just my 2pence,
Gareth

Yes, I used that for another feature in my application.
But, here, the element to setup is more complex than a single value (as it has to be with set-property)
I also tried to use a set of set-property elements, but it becomes a real mess, and it's getting difficult to identify a bug, as there's no way to validate the config.

Re: Best Practices to Customize Struts-Config and its DTD

Did you try extending ActionMapping and using <set-property> inside <action> ?

<action className="MyExtendedMapping"
              path="...">
    <set-property  property="val1" value="foo.bar.anything_you_need" />
    <set-property  property="val2" value="foo.bar.anything_you_need" />
    <forward name="xxx" path="xxx"/>
</action>

This is the only way to be Struts-compliant.
