Ok I've removed the call to init components and spelt realize correctly
this time. The code now reads and still produces the same error as
before at runtime.

I pasted everything in the original post from compilable code. The only
line I typed in on the original post is the realise(); line because I
originally had it in a button event handler. Hence the mistake. Sorry!
I didn't realise I'd made a mistake, sorry to of wasted your time
earlier. However this code should compile.

I'm using netbeans 5.5 ide.
JDK 1.5.0_09 same number jre
windows XP Home Service pack 2

I dont know have a website to post a link to my test3.mid file. However
the code gives the same error with every single midi file I try. So
just pick your favourite midi file and you'll replicate the error, no
problem! If you give it an mp3 file it runs ok, but not midi files.

I should point out perhaps incase there's yet another silly mistake
somewhere, that I picked the name slowlearner for a reason. I suffered
chemical damage to my brain in 1978 from a pesticide accident. It's
only about a 18 months since I've been able to even watch TV or read
let alone program. So I am litteraly a slow learner.

It compiles but doesn't run without a main(). I added a main and it
compiles and runs my mpg file. I don't have a mid file to test with. I
think you can post attachments on this list but I haven't tried it. Post
a small file that duplicates your problem and I'll look at it. If you
can't post attachments, email me a small file.

If you pop over to Roedy's website you'll find plenty of midi files to
try. Even JmStudio cannot play them on my 3 machines. (I tried emailing
you but it bounced)

I'm sorry but I don't have time to look over Roedy's site for midi
files. You can give me the URL of one or you can send me one via email.
  The bounce was probably caused by not substituting knute for nospam.
