How to import an example solution in Servoy 4 ?

How do I import an example solution in Servoy 4 ?
I can see the solution files in servoy/application_server/solutions/examples/
eg. servoy_sample_treeControl.servoy
I can’t figure out how to import the solution in Developer

Open the Admin Pages pointing your browser to http://localhost:8080/servoy-admin and select “Solutions” from the menu on the left.

The solution was already visible on the server admin/solutions page.
I was able to open the solution using File/new/other.
But now I have another problem. I had deleted all the sample database servers. How do I import these back ?
I am getting ‘could not retreive form data’ error

One quick fix would be, to un- and re- install your 4.0 again, that is, if you have not gone so far or done so much with it, :|

Dont think I would like to install again ! Is there any other way ?

You may inspect the folder ,

your_install_drive:\your_install_dir\application_server\solutions

to see if the example solutions that shipped with Servoy 4.0 are still there. If they are, you could probably import them again
through your http://localhost:8080/servoy-admin interface, as suggested earlier by Nicola. Good luck!
