External JAR File [message #568839]

Hello,

first of all thanks for investing so much time and doing such a great
job with MTJ.

I can write some "HelloWorld" code and deploy it to the mobile without
a problem.

I start having problems when I include an external JAR file. I have added
it
correctly in "Libraries" and checked it in "Order and Export". When I
don't use the external JAR in my code, everything works fine. When I
start using it, I get an the following error message:

ALERT: java/lang/ClassFormatError: Bad version information.

The external jar file I am trying to use is
qrcode(http://qrcode.sourceforge.jp).
I have set the "Compile Compliance Level" to 1.4, but that doesn't change a
thing.

I have a hunch that says, that the external jar is in an incompatible
format, but
how can I turn it into a compatible one?

I am using the following software versions:

Eclipse: 3.4.1
MJT: 0.9.0
Java: 1.5.0_16

best regards,
sigi
