Javamail - type exception

I've written a program that uses the javax.mail jar to send email. The program works fine on my desktop computer - but when moved to another station, the Transport.send() method throws an Unsupported Type Exception. Saying therei s no DCH object for my MIME object.
I've seen several posts around with similar problems - the only suggestions are to check the class path. I'm using a jar with all of my mail jars inside, so I don't do any class path setting.
Does anyone know of any hardware problems that could cause this? I was able to open outlook on the other station and send a message.
Here is a cropped portion of the code...

No DataContentHandler, well the only solution to that is to check your classpath... That's almost always the problem, regardless of how sure you are, I really would go and check it again.

I think in one of the jars somewhere there will be a META-INF/mime.types or mime.defaults file, which IIRC tells you the supported mime-types. Perhaps you have conflicting mime.types files due to the installation of java on that 2nd machine.


I have no java certifications. This makes me a bad programmer. Ignore my post.
 
I agree. Here's the link: http://aspose.com/file-tools
