My OS is windows 8.1. I tried 32bit and 64bit jdk 1.6 , 64bit jdk1.7, always this error.

What should I do to solve this problem. Thank you.

A NoClassDefFoundError specifies that a class was available during compile time but missing during runtime. In your case org.fusesource.jansi.internal.Kernel32 is either not available or uninitialized during runtime. Trying adding a reference of Jansi jar to your project. You can refer to this regarding how to debug a NoClassDefFoundError

  • Thank you for your answer. What I confuse is that there is Jansi jar in play repository. Somebody says play 2.x supports java 8 only, I tried, but still this error. – Sealter Nov 17 '14 at 01:25
  • do you see any other error in the stacktrace - ClassNotFoundException or ExceptionInInitializerError? – Crickcoder Nov 17 '14 at 01:41
  • No, only NoClassDefFoundError – Sealter Nov 17 '14 at 01:50
  • you mentioned, you created a new application hello-play-java. When you run this what is the classpath? Are all your jars available to the application? – Crickcoder Nov 17 '14 at 01:55
  • I created the application in firefox when play is started, the location is http://127.0.0.1:8888/home . In play 2.x, there is no play command, so I use activator ui command to start play, when it is started, it will open a page refered above. In this page, it tells me how I can create an app: 1、Choose a template 2、 Specify a location 3、Activate it. So I choose the template of hello-play-java, but I change the location instead of my user home. I installed play in D:\play\activator-1.2.10 and my app was in D:\playtemplate . The jars in D:\play\activator-1.2.10\repository. They're all avaliable. – Sealter Nov 17 '14 at 02:19
