Re: Tapestry 3.0 and Hivemind Integration Resources

[Zachary Pinter <zp...@gmail.com>]

Continuing with the Tapestry 3.0/HiveMind discussion:

I've got the HiveMind Registry/Service properties setup something like this:

public class MyBasePage extends BasePage {
    private static Registry _registry;
    
    public void finishLoad(IRequestCycle cycle, IPageLoader loader,
            IComponentSpecification specification) {   
        HttpServletRequest request =  cycle.getRequestContext().getRequest();
        _registry = HiveMindFilter.getRegistry(request);
        super.finishLoad(cycle, loader, specification); 
    }
    
    public Registry getRegistry()
    {
        return _registry;
    }

    public Object getHive(String name)
    {
        try {
            return getRegistry().getService(Class.forName(name));
        } catch (ClassNotFoundException e) {
            throw new RuntimeException("Couldn't find class "+name);
        }
    }
}

When calling getHive, I pass something like
"myproject.hivemind.services.Login", which gives me a service point
does not exist exception. I'm pretty sure I've got my module in the
wrong place. I use Eclipse/Jetty for development and only use ant for
creating/deploying war files.

I've got a project setup like this:

/src
/classes
/context
/context/css
/context/images
/context/WEB-INF
/lib

Which folder or subfolder should I place the module's xml file in and
what should the file be named? If my module is called module1, should
the file be module1.xml, or hivemodule.xml, or does it even matter?
