Re: Eclipse - java.lang.NoClassDefFoundError: com/sleepycat/je/DatabaseException

Hello guys,

I am having a problem testing an small Java code to be used with Berkeley DB Java Edition. I have created a Java Project, then I've created a package and inside of this package I've created a class with the following code:

<snip>

I do not understand why. The BerkeleyDB jar files are placed already in /System/Library/Java/Extensions and the class compiles correctly. Any idea on why it is not running? What am I forgetting?

Please do not put 3rd party jar files into /System/Library/Java/Extensions. That directory is reserved for use by Apple, and we may blow it's contents away with a Software Update. We reserve the right to rewrite everything in /System. The proper place for this jar is on your application's classpath (either bundled with your double-clickable app, or specified on the command line with your Java invocation).

If you must use an extensions directory, use ~/Library/Java/Extensions, or the system-wide /Library/Java/Extensions. Eclipse probably did not recognize that you added another jar to your extensions, so you may have to remove, and re-add the "Apple JVM" for Eclipse to pick it up.
