webMethods Knowlegebase : CDS API, cannot set user locale (1742142)

Problem

Is there any way to programmatically change the user locale?

Background:

==========

Customer is trying to do change the user locale by using below code:

----------------------

final IDirectorySystem system = DirectorySystemFactory

.getDirectorySystem();

IDirectorySession session = system.createSession();

try {

IDirectoryUser directoryUser = (IDirectoryUser) session.lookupPrincipalByName(userId, IDirectoryPrincipal.TYPE_USER);

if (directoryUser == null) {

log.error(mName, "Can not find user with id: " + userId); throw new SAGSFrameworkException("Can not find user with id: " + userId + " in DirectorySystem");

}

Map<String, Object> userAttributes = directoryUser.getAllAttributes();

userAttributes.put("locale", locale);

session.modifyPrincipal(directoryUser.getID(), userAttributes);

system.destroySession(session);

session = null;

} finally {

if (session != null) { system.destroySession(session); }

}

--------------------

But this produces the following error:

--------------

com.webmethods.portal.PortalException: [POP.001.0001] Methode "setAttribute" wurde nicht implementiert.

-------------

Looking at the source of LdapDirService.java I can see that the method setAttribute has intentionally not been implemented:

----------

public void setAttribute(IURI principalURI, String attrName, Object attrValue) throws PortalException {

throw PortalException.notImplemented("setAttribute");

}

---------

Customer is calling method modifyPrincipal(String principalID, Map attributes) of IDirectorySession, documented here: http://documentation.softwareag.com/webmethods/wmsuites/wmsuite8-2_sp2/My_webMethods/8-2-SP1_CAF_and_MWS_Java_API_Reference/com/webmethods/sc/directory/IDirectorySession.html

They use an LDAP connection to retrieve the userid and password. The locale is stored in MWS.
