This is good stuff -- not sure about a 1.0 release though. We'll try to get a point release out shortly after though to support this.

I've tried running the patch again (through Eclipse) and I get the
same
problem - It only creates patch entries for new files? I know this isn't a subject for this list, but does anyone know why this happens?
Anyway Cameron, I'll create a zip of the changes for now and attach
it
to the the issue and this list.

The patch seems to be missing code in the configuration classes... since I have applied it, I am geting compilation errors :
not defined :
invocation.getProxy().getConfig().getPackageName() invocation.getProxy().getConfig().getExternalRefs(); packageConfig.getExternalRefResolver()
Thanks,

Hi,
As per the discussion late last week, we have a patch for Xwork so that it can use an external container to resolve component
references.
I've created the following issue - http://jira.opensymphony.com/secure/ViewIssue.jspa?key=XW-122
I've added a breakdown of the changes below, in summary, this is how
it works-
You can configure a action to have external references in the xwork.xml using a new <external-ref> tag on the action
When the action is configured the external refs are stored on the action config.
When the action is invoked, there is a new interceptor that will resolve these references. It does this by using a new attribute on the package config called externalReferenceResolver i.e.
<package name="default"
externalReferenceResolver="com.atlassian.xwork.ext.SpringServletContextR
eferenceResolver">
In this case, the SpringServletContextReferenceResolver implementation will handle the work of looking up and setting the references on the action.
Note, if a resolver is not found on the actions package, it will tranverse up the package heirarchy to find one.
We have an implementation for Spring, but I have not included it in this patch as it should probably go into an xwork-ext sub-project. Let me know what you want me to do with this...
Here are the changes and additions to the xwork codebase -
1. added 2 new config attributes - - a new element external-ref to the action element in the
config.
i.e <external-ref name="foo">Foo</external-ref>
where name is the setter method name and Foo is the reference to lookup.
- added an attribute to the package element called externalReferenceResolver which supplies a FQ classname to an ExternalReferenceResolver implementation.
2. Updated the xwork DTD accordingly.
3. Added 4 new classes -
- External Reference - an encapsulation of the external-ref tag
- ExternalReferenceResolver - an interface to provide implementations for resolving references from an external container
- ExternalReferencesInterceptor - will resolve references on a
given
ActionInvocation - ReferenceResolverException - thrown by ExternalReferenceResolver
4. Added support for external references to the ActionConfig. I also
added the attribute packageName to the ActionConfig, so that the Interceptor could determine which package the action belonged to in order to find the externalReferenceResolver.
5. Added support for the externalReferenceResolver attribute to the PackageConfig.
6. Added support for the extra configuration to the XMLConfigurationProvider and DefaultConfigurationProvider
7. Added tests in the org.opensymphony.xwork.config.ExternalReferenceResolverTest
I've attached a cvs patch with all the changes. I built the patch against the latest src.
Cheers,
Ross
