[opencms-dev] How to add a new resource type

[M Butcher]

I should have been more specific.... Here's the code (with imports and 
comments cut out):

class GenericXmlResourceType extends CmsResourceTypePlain {

     public static final String C_TYPE_RESOURCE_NAME = "GenericXML";

      public CmsResource createResource(CmsObject cms, String name, Map 
props,
             byte[] contents, Object param)
             throws CmsException {
         CmsResource res =
             cms.doCreateFile(name, contents, C_TYPE_RESOURCE_NAME, props);
         cms.lockResource(name);
         cvs.writerProperty(name, C_PROPERTY_EXPORT, "true");
         return res;
      }
}

As you can see, it extends com.opencms.file.CmsResourceTypePlain. The 
problem is, the cms.doCreateFile() method is also protected. Since 
CmsObject is in the same package as CmsResourceTypePlain, it works. 
However, my module is in a different package.

Interestingly enough, if I remove the createResource method, it 
compiles. Then, of course, I get a runtime error (access violation) when 
the dynamic classloader loads it at startup. Besudes that, it kinda 
makes it difficult to do anything new when I can't override any of the 
methods that get called. ;-)

I've since moved on to creating a ContentDefinition, but I'm really 
unhappy with that route, as it makes life difficult for the editor (and 
me). In the end, I'll probably hack something together using Plain 
documents.

I'm not really interested in forking the core code, but I am interested 
in finding another way around the problem. Thanks for your suggestion -- 
let me know if you see a way out of this problem.
