Alternative to javax.activation.MimetypesFileTypeMap().getContentType(filename);

Question

I have some code:

import javax.activation.MimetypesFileTypeMap;
...
..
.
String filename = "foo.xls"; // Where this can be any file name .doc, .pdf or whatever

String headerContentType = new MimetypesFileTypeMap().getContentType(filename);

It seems javax.activation.MimetypesFileTypeMap class is inside rt.jar which comes with JRE System library (jdk1.6.0_10) but not in jdk1.5.0

I would like to avoid the use of 1.6 libraries. Anyone knows an easy and quick alternative?

Answer 1

This comes from the activation framework. This is included as standard in Java 6, but is also available as a separate download (for use with Java 1.4 and above)

Answer 2

The particular class is actually part of the java bean s activation framework;

JAF Download

It should not be dependant on 1.6 as far as I know. So simply download the jar, and ensure you have the mimetypes.default available on your classpath.

Answer 3

I've used with success this project SubLuna, it seems more complete than JAF. It uses this mime type collection : Shared MIME Info Specification which is well maintained(of course you will have to replace the file that comes with the library).
