K..I got to know finder tags will generate methods in EntityPersistence class...ie a interface..

But I didnt get to know about..one to many relationship ..??Pls let me clear...

[sheela mk, módosítva 11 év-val korábban]

Its impl is in EntityPersistenceImpl class...But How to get that method from persistence to my portlet class..I mean Layering???

You should use <Entity-name>LocalServiceUtil class to use/call the method from your portlet.

'Service Builder generates a getRegistrations() method in PRUser objects...'

That's exactly what the book 'Liferay In Action' is saying at page 87 (2012 edition), after showing how to relate PRUser and PRRegistration.

Precisely the book had to say 'getUserRegistrations()', but i thought it as a typo. In any case i downloaded the sources of the book examples and
even there this method does not exist.

Furthermore the book does not use this method, so I can't know how to use it or if I'm doing something wrong.

Can we have some clarifying explanation from the liferay team ? I browsed forums and tutorials for a week without any solution, and only more questions raised

I'm using Liferay 6.1 GA1.
