You can

• make a filter (javax.servlet.Filter)
• map it to /
• check request.getServerName() and compare with a predefined list of domains
• request.getRequestDispatcher("/someIndex.jsp").forward() depending on the domain.

However, it looks like a strange use-case, because the user will still be able to access the index files for other domains if he knows them (if they are not hidden in WEB-INF). But without knowing your requirements I can't suggest a better solution.
