Perhaps I am using the wrong scope, but I didn't expect to see A(Scope.OBJECT) the existing entry and the delete but not the add, or B (Scope.ONELEVEL): not the existing entry but the delete and add. I _think_ there is an issue with evaluating scope in psearch, I will check and let you know have fixed this[1] in trunk if you want to build from sources do: 1. svn co https://svn.apache.org/repos/asf/directory/apacheds/trunk-with-dependenciestrunk 2. cd trunk 3. mvn clean install -DskipTests (remove -DskipTests if you want to run tests, but this takes around 15 minutes to build) [1] https://issues.apache.org/jira/browse/DIRSERVER-1874 -- Met vriendelijke groet, Alexander Broekhuis -- Kiran Ayyagari http://keydap.com -- Met vriendelijke groet, Alexander Broekhuis -- Kiran Ayyagari http://keydap.com -- Kiran Ayyagari http://keydap.com

But somehow I don't yet fully understand the principles behind the API. I am not familiar with LDAP and/or JNDI, so perhaps I am missing some basic knowledge. Would it make sense to read more about LDAP and JNDI to understand how I should use the API? Don't read anything about JNDI : this API is pure crap, and diverge from LDAP so much that it will make you having headaches... Reading a few things about LDAP would help though. OTOH, we should update the site to give more information to users ;-) The problems I am now running into are: I am trying to make a listener like class that tracks a certain DN. So I am using a persistent search and for each entry I can call a callback method. But I don't know how to tell what the ChangeType of a new entry (updated cursor) is. With the PersistentSearch, you will be get back any entry that has been modified, but you won't know which modification has been done on the entry. For that, you have to check the EntryChange control that is returned with any SearchResultEntry. What I could find was that I need to use the EntryChange control from the response. To do this I now use setReturnECs on the PersistentSearch control, but I can't find any controls on the Response I get from the Cursor. What am I doing wrong? We are chekcing if ther eis not a bug in this area... this is again due to not having the proper control factory, replace earlier property setting with System.setProperty( StandaloneLdapApiService.DEFAULT_CONTROLS_LIST, org.apache.directory.api.ldap.codec.controls.cascade.CascadeFactory, + org.apache.directory.api.ldap.codec.controls.manageDsaIT.ManageDsaITFactory, + org.apache.directory.api.ldap.codec.controls.search.entryChange.EntryChangeFactory, + org.apache.directory.api.ldap.codec.controls.search.pagedSearch.PagedResultsFactory, + org.apache.directory.api.ldap.codec.controls.search.persistentSearch.PersistentSearchFactory, + org.apache.directory.api.ldap.codec.controls.search.subentries.SubentriesFactory ); then you will be able to see the complete details of the control's value, otherwise you see only the OID and below are few more properties if you ever want to use other/extra controls System.setProperty( StandaloneLdapApiService.EXTRA_CONTROLS_LIST, org.apache.directory.api.ldap.extras.controls.ppolicy_impl.PasswordPolicyFactory, + org.apache.directory.api.ldap.extras.controls.syncrepl_impl.SyncDoneValueFactory, + org.apache.directory.api.ldap.extras.controls.syncrepl_impl.SyncInfoValueFactory, + org.apache.directory.api.ldap.extras.controls.syncrepl_impl.SyncRequestValueFactory, + org.apache.directory.api.ldap.extras.controls.syncrepl_impl.SyncStateValueFactory ); System.setProperty( StandaloneLdapApiService.DEFAULT_EXTENDED_OPERATION_REQUESTS_LIST, org.apache.directory.api.ldap.extras.extended.ads_impl.cancel.CancelFactory, + org.apache.directory.api.ldap.extras.extended.ads_impl.certGeneration.CertGenerationFactory, + org.apache.directory.api.ldap.extras.extended.ads_impl.gracefulShutdown.GracefulShutdownFactory, + org.apache.directory.api.ldap.extras.extended.ads_impl.storedProcedure.StoredProcedureFactory, + org.apache.directory.api.ldap.extras.extended.ads_impl.pwdModify.PasswordModifyFactory ); System.setProperty( StandaloneLdapApiService.DEFAULT_EXTENDED_OPERATION_RESPONSES_LIST, org.apache.directory.api.ldap.extras.extended.ads_impl.gracefulDisconnect.GracefulDisconnectFactory ); -- Regards, Cordialement, Emmanuel Lécharny www.iktek.com -- Kiran Ayyagari http://keydap.com

Hi all,
I am looking into ApacheDS and the Api to work with the server. I am trying
to implement some of the examples used in the documentation, but there are
several small things differently with the latest release? Eg a
connection.search(String, String,) returns a EntryCursor, and not a
SearchCursor, whereas a connection.search(SearchRequest) does return a
SearchCursor.
So a first question, why this difference? And what way is the
best/preferred way to do a search etc?
EntryCursor is used when you expect only entries (not referrals) in the
results
SearchCursor gives you all entries and referrals (if present) as well
My next question is about PersistentSearch, how do I do this? For example,
I have the following code:
SearchRequest searchRequest = new SearchRequestImpl().setBase( new Dn(
ou=system ) ).setFilter( objectclass=*)).setScope(
SearchScope.ONELEVEL).addControl( new PersistentSearchImpl() );
SearchCursor cursor = con.search(searchRequest);
while (cursor.next()) {
Response response = cursor.get();
System.out.println(((SearchResultEntry)response).getEntry());
}
cursor.close();
When I run this code without the Control it returns the entries I expect,
but with the Control, it somehow blocks at cursor.next(). I am not even
sure this is the correct way to do a persistent search, I can't find any
documentation on this at all. Also, when I have a persistent search, how
can I get a call that the result has been changed? Eg entry added/removed
etc.
you get the results asynchronously, i.e, you leave the loop running and it
will wait for
the incoming results, just make sure you increase the timeout either at the
connection (setTimeOut)
level or in the SearchRequest (setTimeLimit())
Thanks,

It would be cnvenient to have a persistentSearch() method hich returns a
future, and you should have a non-blocking method to get a result when
called, beside a blockig method.
Wdyt ?
