Interface enum listing standard mime-type constants

Question

I am looking among the standard libraries  like apache commons  jax  jboss  javax  for an interface or enum that lists the values of all the standard mime-type  aka content-type    This interface should not be encumbered with too deep with other classes that would make it difficult to include the whole bunch as gwt source code   for example  interface ContentType    String JSON    Application JSON     blah     blah         or   enum ContentType    JSON  Application JSON      blah     blah

If you re on android you have multiple choices  where only the first is a kind of  enum     HTTP  which has been deprecated in API 22   for example HTTP PLAIN TEXT TYPE or MimeTypeMap  for example final String mime   MimeTypeMap getSingleton   getMimeTypeFromExtension extension   See also FileProvider getType    URLConnection that provides the following methods     guessContentTypeFromStream InputStream is  guessContentTypeFromName String url  getFileNameMap      For example   Override public String getType Uri uri        return URLConnection getFileNameMap   getContentTypeFor              uri getLastPathSegment

Java 7 to the rescue   You can either pass the file or the file name and it will return the MIME type   String mimeType   MimetypesFileTypeMap      getDefaultFileTypeMap        getContentType attachment getFileName       http   docs oracle com javase 7 docs api javax activation MimetypesFileTypeMap html

As pointed out by an answer above  you can use javax ws rs core MediaType which has the required constants    I also wanted to share a really cool and handy link which I found that gives a reference to all the Javax constants in one place - https   docs oracle com javaee 7 api constant-values html

As already posted in earlier answer  most common MIME types are configured in a webserver  For example in tomcat conf  we have web xml with following MIME configured       lt mime-mapping gt         lt extension gt abs lt  extension gt         lt mime-type gt audio x-mpeg lt  mime-type gt      lt  mime-mapping gt      lt mime-mapping gt         lt extension gt ai lt  extension gt         lt mime-type gt application postscript lt  mime-type gt      lt  mime-mapping gt      lt mime-mapping gt         lt extension gt aif lt  extension gt         lt mime-type gt audio x-aiff lt  mime-type gt      lt  mime-mapping gt        Create a startup listener that kicks in when web app is started and parses this XML file and creates the ENUMS for you and binds it to servlet context for sharing downstream
