need advice for wicket-plugin's implementation
Hi
I'm working to first version of wicket-plugin. I encounter some problems.
In few words I implemented a PluginManagerInitializer that create a
PluginManager, load and start the plugins from a directory
and store the plugin manager to application using wicket meta data.
Each plugin is loaded with a PluginClassLaoder.
I want to map each plugin's resources on ./plugin/plugin-name/...
My problem is how to create a reference to a plugin resource.
See this code:
@Extension
public static class HelloSection extends SimpleSection {
public HelloSection() {
//super(new Model<String>("Hello"), new
PluginResourceReference(HelloSection.class, "settings.png"));
super(new Model<String>("Hello"), new
PackageResourceReference(HelloSection.class, "settings.png"));
}
}
In above code I want to add a new tab (section) to my TabbedPanel (I created
a demo application with a tabbed panel and itabs from plugins)
but HelloSection.class is not visible to wicket (I retrieve a
CastClassException).
It seems to me that I cannot use ResourceReference in my case because
"scope" parameter (must be visible in wicket but I want something relative
to plugin baseResourcesPath).
Any advice how can I implement my idea is welcome.
Best regards,
Decebal

See CompoundClassResolver. Designed for this purpose.

Hi,
Since you use custom ClassLoaders you have to use custom IClassResolver too.

Re: need advice for wicket-plugin's implementation

Hi
I will abort the solution with ResourceReference.
I will try to use a IRequestMapper (PluginResourceMapper) for each started
plugin (if request url is ./plugin/plugin-name/...). The mapRequest() method
will return a ResourceRequestHandler (PluginResourceRequestHandler) that
returns a ContextRelativResource (PluginResource) on getResource() method.
Each wicket plugin has a method getPluginResourceUrl(String relativePath) -
with a possible implementation
getRequestCycle().urlFor(PluginResourceRequestHandler).toString().
Does this make sense?
Best regards,
Decebal
