Service Builder Migration from 6.2 to Liferay DXP

[6年前 に sony sing によって更新されました。]

There have two tables taken from Liferay 6.2 databse in DXP database. (Did it in database migration).

I took reference from blade sample & created service builder by refering exact service.xml from liferay 6.2's (Service Builder).
It builds well and deploys too.


In UserSubscriptionsLocalServiceImpl I have added following method

public UserSubscriptions searchUserSubscriptions(String userId){
try{
return userSubscriptionsPersistence.findByUserSubscriptionsByentryUUID(userId);
}catch(Exception e){
}
return null;
}


But while executing following method I get ClassCastException.

UserSubscriptions userSubscriptions = UserSubscriptionsLocalServiceUtil.searchUserSubscriptions(themeDisplay.getUser().getScreenName());

Exception -
2017-11-08 01:30:07 ERROR DispatcherPortlet:559 - Could not complete request
java.lang.ClassCastException: com.sun.proxy.$Proxy958 cannot be cast to com.agco.dealer.engage.email.service.UserSubscriptionsLocalService

PFA
service.xml & log files

When in OSGi, try to avoid use of the static util classes.

If you @Reference to inject your UserSubscriptionsLocalService, I believe you'll find this class cast thing goes away.
