Answer 1

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.

Answer 3

There is now also the class org.apache.http.entity.ContentType from package org.apache.httpcomponents.httpcore, starting from 4.2 up.

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());
