I know that this is probably the stupidest question that I have ever asked but here goes.......

I am trying to create a new application in netbeans..... and having no luck at all.

First I create a new project called Interactive Campaign Manager by choosing java category and then Java Application project.
This creates the project

Next I create a new file called Main using application sample form.

When I run these essentially empty do nothing but display a blank form area with a menu bar with 3 items,

I either get a message BUILD SUCCESSFUL (total time: 2 seconds) without anything displayed at all....

or I get the following error:

run:
java.lang.NoClassDefFoundError: interactive/campaign/manager/InteractiveCampaignManager
