finding length of wma in java

finding length of wma in java

I am a bit confused about all of the various sound apis available in java.
All I need is something to determine the length of a wma file. I don't
need to play it or convert it or anything else. I understand that the
native java api doesn't support wma. Can anyone recommend a good
library/method that can easily get the length of a wma? (I found JAVE from
searching here, but it seems like overkill in terms of setting up for just
determining the length.) It will run on a Windows computer if that's
relevant.
