Hi, I have problem to run the sample under ~/ozone/doc/tutorial, during followed the tutorial. I got the message "Exception in thread "main" java.lang.NoClassDefFoundError: javax/transaction/xa/XAResource at MyApp.main(MyApp.java:16)", when I typed "java MyApp create". Where was wrong? The version of Java is 1.2.2 Thanks for your help. /Fukang/
