General Discussion

The Apache Jakarta Commons Lang package (as of version 2.2) contains a StringEscapeUtils class that contains this functionality. See the escapeHtml(String) method. The documentation states:

   Escapes the characters in a String using HTML entities.
   Supports all known HTML 4.0 entities, including funky accents. Note that the commonly used apostrophe escape character (') is not a legal entity and so is not supported).

Why go to all the trouble of computing int len and running the for loop if the input String is null? I suggest adding a sanity check to the top of the method:

   if (s == null) return "";
