VASSAL modules are created using VASAAL's GUI-based module builder and optional custom Java classes if needed. Modules run in desktop client app. To run the modules server-side as-is, I think you'll need to use a server-side JSwing frameworks. Re module building part of VASSAL, I think it'll be easier to rewrite entirely. IMO, more serious issue is copyright issues in hosting VASSAL modules server-side.
