Max, I will think how to form this request, what exactly to suggest as nice feature...
Juergen, thank you for issue, but it looks to be very particular, you ask for adding certain jars to Server Runtime libraries and that's ok, the issue I try to raise is more about customization. javax should be here by default (as it is "javax" ;) ), all other jars or modules can be added by wish. It can be done like using relative path (so it won't hurt other team members), and e.g. list of all jars and checkboxes which to add (showing them by modules for easy looking for...). Well, something like that ;)
