Hello, I am still trying the v2.0 installation. I have reinstalled eclipse and the app engine plugin and then followed the instructions at: http://code.google.com/p/datanucleus-appengine/wiki/UpgradingToVersionTwo
all went well but in the very last step when I enabled the auto enhancement I got: Exception in thread "main" java.lang.NoClassDefFoundError: org/datanucleus/enhancer/DataNucleusEnhancer Caused by: java.lang.ClassNotFoundException: org.datanucleus.enhancer.DataNucleusEnhancer at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: org.datanucleus.enhancer.DataNucleusEnhancer. Program will exit. This is the only part which is not working for me. How can I fix it?
