The SOMClassMgr object uses the somLocateClassFile method when executing somFindclass to obtain the name of a file to use when dynamically loading a class. The default implementation consults the Interface Repository for the value of the dllname modifier of the class; if no dllname modifier was specified, the method simply returns the class name as the expected filename.
If you override the somLocateClassFile method in a user-supplied subclass of SOMClassMgr, the name you return can be either a simple, unqualified name without any extension or a fully-qualified file name. Generally speaking, you would not invoke this method directly. It is provided to permit customization of subclasses of SOMClassMgr through overriding.
