Oracle JDeveloper - browser Opening issue

I am trying to build an application (Hello World) in Oracle JDeveloper and run. It ran fine. But i开发者_如何学编程t doesn't open in default browser. I edited Tools--> Preferences --> Web Browser and Proxy --> gave C:\Program Files\Internet Explorer\iexplore.exe . It doesn't work. I could not even try preview.

Please help me.

Thanks,

What kind of application are you trying to run? A simple hello world will not open in a browser. It must be a JSP or Servlet to open in a browser. Please post your code and I'll take a look.
