hi
you can use service builder for create relation in your mvc portlet
Service builder is very power full tools from liferay for generate low level class in mvc pattern

but i don't learn and know about
i know:
1- i new one service builder after new service builder create on file named service.xml
2- in the service.xml define my table and its fields and relation
i don't know about:

1- don't how to use or run from this file (service.xml) correctly
2- does this file (service.xml) generate getter or seter file ?
3- does this file (service.xml) generate tables in my database?

Hi Maryam,

When you build service all the classes are created also impl, persistance, etc. Also one sql folder is created inside "[Your-Portlet-location]/docroot/WEB-INF" folder, where you can see the tables, indexes, sequences sql files.
Now when you ant-built(or deploy) your portlet it generate tables in my database.

Also getter n setter methods are created inside "src/com.../model/impl" there is one ***ModelImpl.java class, where you can find the getter/setter methods.

Regards,
Raja

Hi Maryam,

Steps which you have shown are correct. I too created sample portlet and run the service-builder its working fine as per the scenario. Check with your Liferay IDE. Have you created any sample portlet before with Liferay IDE? If not try this scenario with normal eclipse.

Regards,
Raja

Raja please add me or if u like to send for me gmail id beacause is faster
how to build your file? with buttom show in picture 3 ?
in your sample , u use spring or hibernate?

[Raja Seth, módosítva 12 év-val korábban]

Hi,

- If you are using normal eclipse, you can right click on build.xml and run as ant built.
- If you are going through command prompt go to your portlet path, for example "D:\liferay-developer-studio\examples-plugins-sdk\portlets\sample1-portlet>"
and do ant build-service.

Liferay by itself uses hibernate platform as liferay-service. My portlet is normal MVC portlet.

Have you tried googling your question: Liferay service builder one to many
