What's the right content-type for a Java jar file?

Question

I'm uploading some jars into s3 and want to set the right content-type headers for them.

I looked through what I thought was a comprehensive list, and was unable to find any mention of jar.

Answer 1

I found a list which might be very useful to some.

You can find a more complete (but still incomplete) list of MIME-Types here from the official Mozilla Developers Network.

For Java Archive (JAR) .jar files the correct type is indeed:

.jar   |   application/java-archive

Answer 2

I have seen instances of these content-type headers for JAR files:

application/java-archive

application/x-java-archive

application/x-jar

Answer 3

Oh, wikipedia says it's application/java-archive though I don't see that in any rfc or standards document.
