Static methods can be invoked with a null object reference.
It would look something like this:
String className = "com.mywebsite.application. " + tablename + "Peer";
Class[] types = new Class[] {Criteria.class};
Object[] parameters = new Object[] {new Criteria()};
Class peerClass = Class.forName(className);
Method select = peerClass.getMethod("doSelect", types);
List results = (List) m.invoke(null, parameters);
Untested of course but it should be close.
