Error while Running MIDP 2 applications in netbeans

I am trying to run(emulate) a simple midp2 j2me application in netbeans(6.8) in ubuntu 10.04. It is building fine , with no errors, but when i choose run , it gives "http server is not running.start it first" error. I am able to successfully build and run it using the java wireless开发者_C百科 toolkit. But using Netbeans would be easier.

Reinstalling Mobility plugin in Netbeans 6.8 worked for me.

I think in your coding u make use of server/servlet,etc.So before executing ur application run the server then execute the application .Then it works.
