problem in running helloworld

Posted by mehdi sarikhani at February 06. 2012

Hi

i made a hello world project, according to manual and attached picture. It have problem to main class. actually it can make HelloWorld.class.

So if i want to run this project i can run by changing run configuration (just by changing the Project from hello-world to build-area).

in this way also i can not import hello -world actor into Kepler by Tools->Instantiate Component .

what can i do to solve this problem?

i will appreciate if you can give any suggestion that you have, in oder to solve this problem.

Cheers

Hi Mehdi,

Are you able to import the hello-world actor if you run from the command line using ant?

ant change-to -Dsuite=hello-world
ant run
