This was one of the issues that the SDO spec collaboration workgroup was looking at for SDO version 2.1, but unfortunately it wasn't resolved in time for 2.1 so now is on the 3.0 list. At Tuscany, we were waiting for the spec to set the direction before implementing something for this, so it's not currently supported.
If you need to use readonly properties today, then if you are using static SDOs you can, as Dan mentioned, add set methods into your generated classes. If you are using Dynamic SDO we'll need to add some methods to DynamicDataObjectImpl/SDOUtil to let you call some of the internal EMF methods to do this. If you need this urgently, please open a JIRA and we'll see what we can do (maybe you would like to help?). Otherwise, I would avoid using readonly properties for now, and wait for SDO to define a proper SPI for doing this.
