injecting services/objects to "external" POJOs

Hi,

I often need access to services or other objects in the registry from "external" classes. On "external" I mean some class which does not have implicit access to the registry. These are usually smaller utility/definition classes, like table models, table column definitions, etc. in case of Tapestry.
Is there an existing solution for this problem? (Like a special classloader which can inject objects to any class, similar to Tapestry's solution.)

Thanks,
Norbi

You can use annotations since something like @InjectObject utilises the 
ObjectProviders configuration.

Could you not do something like this:

@InjectObject("instance:com.test.MyTableModel")
public TableModel getTableModel()

there are also bean and spring object providers already defined that you 
could use.

I would prefere an annotation-based solution because for example I create the table columns dynamically (using the new operator).

  Maybe you should have a look at hiveutils.ObjectBuilder service (and the ObjectBuilderObjects configuration)? This is part of HiveMind Utilities.
