John,
I am compiling Braille Blaster and the DLLs using version 7 of the Java JDK.
I am having no problems with running what I compile on the same Java
version. I just gave a copy of my 32-bit version to a friend to try out. He
is running Java version 6. It won't run. He gets the below error. I also
tried it on my laptop, which also has Java 6, and got the same error.
Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/brailleblaster/Main : Unsupported major.minor version 51.0
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClassCond(Unknown Source)

at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: org.brailleblaster.Main. Program will exit.
Any ideas what would cause this? Will I have to compile with Java 6? If so,
will it run on Java 7?
Is anyone running my 32-bit Windows release of Braille Blaster 1.3.0
successfully? If so, what Java version do you have?
Best regards from Ohio, U.S.A.,
Vic
