So this line:

guestbookFinder: com.liferay.docs.guestbook.service.persistence.GuestbookFinder UNSATISFIED 1..1 static target=(*) scope=bundle


This tells you that your GuestbookLocalServiceImpl has an @Reference dependency on a GuestbookFinder, but it is not finding one.

So this points to your GuestbookFinder not starting and/or not registering. Do you have this corresponding info on the GuestbookFinder?  Can you share some or all of your GuestbookFinder class?

Hi David,
Please see the attached for all source code.

Yes, correct and agree that GuestbookLocalServiceImpl has an @Reference dependency on a GuestbookFinder and can't find.

guestbookFinder.findByEntryNameEntryMessageGuestbookName(entryName, entryMessage,guestbookName, begin, end); is calling within GuestbookEntryLocalServiceImpl .

Please suggest how should i fix it. I am using liferay 7.2 GA1. I also attached web portlet as well. Thank you

You cannot @Reference a class that is not itself an @Component.

Your GuestbookFinderImpl is not an @Component, so OSGi has nothing to inject.

Thank you so much David,
Firstly i tried to put @Component in GuestbookFinderImpl but it is also fail.  Finally i changed following without using @Reference and it is working.

From GuestbookFinderImpl class
---------------------------------------------------
String sql = CustomSQLUtil.get(
//                String sql = _customSQL.get(
                    getClass(),
                    FIND_BY_ENTRYNAME_ENTRYMESSAGE_GUESTBOOKNAME);
//        @Reference
//        private CustomSQL _customSQL;

From build.gradle
-------------------------------
compileOnly group: 'com.liferay', name: 'com.liferay.portal.dao.orm.custom.sql', version: '1.0.22'
runtime group: 'com.liferay', name: 'com.liferay.portal.dao.orm.custom.sql', version: '1.0.22'

from bnd.bnd
-------------------------------
Import-Package: \ *
-includeresource: \ @com.liferay.portal.dao.orm.custom.sql-1.0.22.jar

from service.xml--------------------------dependency-injector use with spring. Earlier with ds. <service-builder dependency-injector="spring"  package-path="com.liferay.docs.guestbook" mvcc-enabled="true">
