I am getting the above exception while run the 'ant dist' command at command prompt. I have installed ruby & sencha command. I am using java "1.5.0.06" and jre 6 in my system.

I am getting same exception while running 'sencha.exe' from command prompt.

Please help me to solve this. Thanks.

  • What does it mean that you use Java 1.5 and JRE 6? Those are two different versions. Sencha requires Java 6, so check if you are running it on Java 1.6.x, also the new version requires Java 7, see http://cdn.sencha.com/cmd/beta/4.0.0.126/release-notes.html – Martin Strejc Nov 07 '13 at 06:58
  • Thanks Martin. I am using Java 6 only. – user2182307 Nov 07 '13 at 10:15
