it doesnt start the server. it just opens CMD and closes it
if you click on it and it is still just opening it and closing it really fast, then you need to go and click on the start orb and go to Computer and navigate to C:\Program Files (x86)\Java\ and then click on the jre folder that has a bunch of numbers after that. Then go into the bin folder and copy the path.
Then you need to click on the start orb again and this time right click on Computer and click on properties. Then click on Advanced System Settings.
Then click on Environment Variables.
Then under System Variables, find Path and click Edit.
Then hit the "Home" button on your keyboard and paste the path that you copied before, before anything else in the path variable. BE SURE TO PUT IN A SEMICOLON ";" AFTER THE "N" IN BIN. For example: C:\Program Files (x86)\Java\jre1.6.0_22\bin;
And thats it, now it should work!
