J2ME

dear all

I developed a J2ME application in Netbeans. It was running well last day. but now whenever i run the project It redirects the page on j2me Default form as displaying Hello! Hello Word screen rather then to display my activeform

what would be the problem in it?

(as application it should display the mainform but it displaying now the default string used by j2me as hello hello world.
