NetBeans open project problem

I just copied whole project into place in system where NetBeans stores projects (in windows it's user\username\Documents\NetBeansProjects\ by default), then started NetBeans and voila - worked great :)

You can try this:

1. Create a new project on the target machine
2. Find where the project you want to open is stored and open the src folder.
3. Copy all the files and stuff in the /src folder
4. Go on Netbeans, expand the tree view of the project you have just created, right click on source packages and click paste. It should paste the files in the /src folder as packages. You should also see the code these packages contain.

Try using create new project from existing resources. This may solve the issue.
