Hello,
I am trying to create a custom JDBC user store by extending the
org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager. For the moment, I just
implemented the doListUsers method to display them in the IS. But I can't
even list my users because I have two problems:
- The first one concerns the method to count the retrieved users. I noticed
the default used class
is org.wso2.carbon.identity.user.store.count.jdbc.JDBCUserStoreCountRetriever
but it seems to use the SQL request defined in the properties to execute
the count. So I configured my user-store configuration file to use my
custom JDBCUserStoreManager as "UserStoreCountRetriever". But now, the
error appearing is it want to execute the "countUsers" method that I can't
even see in the source code in [1]. Which interface/class should I
implement/extend to allow my custom JDBCUserStoreManager to use itself as
"UserStoreCountRetriever". I ask that because I have not found the source
code of this class :(
- The second one is the content of the list of users itself. So the call of
the doListUsers. My SQL request is executed but I have a problem because a
stacktrace appears tellming me that a NPE occured in the class
UserRealmProxy and I don't know what to do:
[2017-07-27 11:03:45,555] ERROR {org.wso2.carbon.user.mgt.UserRealmProxy} -

In addition, I followed the documentation [1] but it is not complete
because the part to register the OSGi bundle is missing. So I followed the
end of the tuto [2] to do so (the part "Register Custom User Store Manager
in OSGI framework"). And if I can make a comment, most of the tuto does not
display which packages to use which is very wrong (hopefully, there was a
sample :)) because there is a big difference between importing
org.wso2.carbon.user.api.UserStoreManager and importing
org.wso2.carbon.user.core.UserStoreManager. There is no way to know which
one to use.
Can you help me, please?
Regards,
Thomas
