my goal is to achieve something like this.

UserLocalServiceUtil.getUser(userId).getContact().getBirthday();

in custom service builder portlet.

Like the comment says, if you include a reference to the User entity, then SB will inject the UserLocalService into your XxxLocalServiceImpl. You'll be able to access it directly rather than going through the static utils.

Same kind of thing if you add a reference to the Contact entity, you'll get the ContactLocalService injected into your XxxLocalServiceImpl class.

There's no magic, there's no portlet even. You will just get the referenced services injected and you can use them in your XxxLocalServiceImpl to fetch the data from these other entities.

thank you for your great explanation.

im not sure that im missed something or not, an error occurred before disappear after modified service.xml

below are service.xml

<entity name="Student" table="student" local-service="true" remote-service="false">
		<column name="studentId" type="long" primary="true" id-type="increment" />
		<column name="name" type="String" />
		<column name="addressId" type="String" />
		<column name="createdDate" type="Date" />
		<column name="modDate" type="Date" />

		<reference entity="Address" package-path="com.liferay.testsb" />
	</entity>
	<entity name="Address" table="address" local-service="true" remote-service="false">
		<column name="addressId" type="long" primary="true" id-type="increment" />
		<column name="street1" type="String" />
		<column name="street2" type="String" />
		<column name="street1" type="String" />
		<column name="city" type="String" />
		<column name="createdDate" type="Date" />
		<column name="modDate" type="Date" />
	</entity>

please advice.

You only use reference for entities from a different service.xml, not entities in the same service.xml file.

Hi,

Address entity reference should be directly available as this entity is generated in the same module so i think you don't need to refer them in the same service builder.
