Re: How to get all ESX hosts from a vcenter

As Laurent pointed out, open source vijava can help that with one line like the following:

  ManagedEntity[] mes = new InventoryNavigator(rootFolder).searchManagedEntities("HostSystem");

Check out more with the Hello World sample:

For the support, you can try the commercial version vijavaNG:

Good luck!
