wangfeng commented on TUSCANY-2253:
-----------------------------------

In version 1.1,tuscany will use the display name to generate the domain uri.So if you use 1.1 and the display name is not be set ,it will throw an null pointer exception.

But in version 1.2,the generating algorithm have been modified and the display name has not be used any more.

What version are you using? can you try the latest version that can be downloaded from [1].
