java.lang.UnsupportedClassVersionError: Bad version number i

Postby ujohnc00 » Dec 2nd, '10, 21:40

Hi there. I just downloaded SDBExplorer for OSX and tried to run it, but it opens then quickly closes with no clues. So I tried to run the 'SDBExplorer.jar' file and got the following stack trace:

Code: Select all
/Downloads/SDBExplorer_osx_2010100101\ 2/SDB\ Explorer.app/Contents/MacOS/JavaApplicationStub ; exit;
[LaunchRunner Error] com.simontuffs.onejar.Boot.main(String[]) threw an exception:

Any guidance?

Can you send us your java version installed ?

Open Terminal.
Write command “java-version” and hit enter you will find java version.
Send Us that Java version.



You probably run SDB Explorer on Java 5. You need to run new version of SDB Explorer under Java 6.

Thanks.

SDBex not working on Mac OSX 10.5.8 ?

Postby Bernard Sfez » Jan 23rd, '12, 08:35

Hello,

I have launched successfully SDBexplorer on my MBPro 10.6.5 and on a Win7.
My workstation at my office is an iMac9,1 (Intel Core 2 Duo) 10.5.8 and the program is not working. On double-click i can see there is a launch of it and then the application exit without messages.

I have check software update and everything is up to date.
My java version seams ok.

:~ raphael$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-9M3425)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)

If i open the package and launch 'SDBExplorer.jar' the application is working and i can manipulate data.
