Re: [dali-dev] how do I generate entities from a different schema

[Neil Hauge <neil.hauge@xxxxxxxxxx>]

Tom,

We have some problems with schema selection that we plan to address in 
M6.  I think there is a way to do what you want to do now though, if you 
can avoid the holes.  First, make sure you are not connected to the DB 
(you may have to restart your workspace if you were connected) and then 
select the Generate Entities menu item on a persistence project.  When 
not connected, this will bring up a dialog that will allow you to pick 
the connection/schema you wish to generate from.  From here you can 
select a non-login schema and generate entities.

Also, you should pick up the latest JPA I-Build from last week, since it 
has a number of additional features (including entity validation) and 
should be more stable than the M5.

Let me know if you have any questions.
