getUserByScreenName vs importLDAPUserByScreenName

[6年前 に Neil Tran によって更新されました。]

Hi everyone,

I can search for a long list of users i.e 100 users. using the first method without a problem.

User exuser1 = UserLocalServiceUtil.getUserByScreenName(companyId, screenName);

However, I cant use this method to search for a long list of users. i.e 100 users.

//not this method
//PortalLDAPImporterUtil.importLDAPUserByScreenName(companyId, screenName);

I have this error.

java.lang.NullPointerException
at com.liferay.portal.security.ldap.PortalLDAPUtil.getNameInNamespace(PortalLDAPUtil.java:441)
at com.liferay.portal.security.ldap.PortalLDAPImporterImpl.importGroups(PortalLDAPImporterImpl.java:816)
at com.liferay.portal.security.ldap.PortalLDAPImporterImpl.importLDAPUser(PortalLDAPImporterImpl.java:243)
at com.liferay.portal.security.ldap.PortalLDAPImporterImpl.importLDAPUserByScreenName(PortalLDAPImporterImpl.java:432)
at com.liferay.portal.security.ldap.PortalLDAPImporterUtil.importLDAPUserByScreenName(PortalLDAPImporterUtil.java:82)


Why is that and what is the difference between the two methods?

Thanks

Screen names are supposed to be unique in Liferay.

getUserByScreenName() is a getter method that returns a user object while importLDAPUserByScreenName() will grab a user from your LDAP environment based on a screen name and then create/import the user into your Liferay environment. If your Liferay instance requires screen names to be unique, the second method should only let you import/create a user once.
