Error using Zephyr

[Sergio Valcarcel]

Hi,

After some time-out I am back with RLPark and Zephyr.

I am starting from scratch and tyring to setup Zephyr. I guess that I followed all the steps given in the introduction, but when I try to run my Rlpark example project in Zephyr I got the following error message:

Exception in thread "ZephyrRunnable-0" java.lang.UnsupportedClassVersionError: my/example/MyExample01 : Unsupported major.minor version 51.0

Also, if I try to run it from Eclipse, I got a similar error:
java.lang.ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

My example is basically the Off-PAC Puddle World with another name :-) and it seems to work fine (I see the 2D output in the console) without Zephyr.

Please, may you have any idea where to debug?

Thanks!

My apologies!

When I use

  public static void main(String[] args) {
    new OffPACPuddleWorld().run();
  }

it works fine, so it must be a problem with my project.

Thanks!

Mmm... I got a mess with different versions of my project...

Although it compiles and run well in the console, it still does not work in Zephyr.

Hi,

Sorry, for so many mails... it finally works. The problem was the plugin configuration. I just followed the instructions very carefully and works fine.

Thanks!
