Subject [jira] [Commented] (DIRAPI-202) Can't get LdapConnectionTemplate working

lucas theisen commented on DIRAPI-202:
--------------------------------------

[~Chris Harris], I do not see a {{mail}} attribute on your attribute list [here|https://issues.apache.org/jira/browse/DIRAPI-202?focusedCommentId=14107847&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14107847].
 Perhaps you are trying to read an attribute that doesn't exist on the Entry?

Try wrapping your EntryMapper.map method body in a try/catch:

{code:java}
@Override
public Muppet map( Entry entry ) throws LdapException {
    try {
        return new Muppet() 
                .setCn( entry.get( "cn" ).getString() ) 
                .setGivenName( entry.get( "givenName" ).getString() ) 
                .setMail( entry.get( "mail" ).getString() ) 
                .setSn( entry.get( "sn" ).getString() ); 
    }
    catch ( Exception e ) {
        System.out.println( "GOTCHA: " + e.getMessage() );
        e.printStackTrace();
    }
} 
{code}

If you see an exception there, it may have more details as to what is actually going on...

> Hi,
> I’ve been following the example code from Section 2.10 using v1.0.0-M24.  My goal is
to use an LdapConnectionTemplate to bind to AD, return a response/cursor, and use an EntryMapper
to map each cursor iteration’s value to a Person object.
> I’m getting the following error message:
> ERR_02002_FAILURE_ON_UNDERLYING_CURSOR Failure on underlying Cursor
> I’m not sure what’s wrong at this point.  I have a basic query example working that
doesn’t use a template.
> I’m including my code, which contains the method with the basic query that does work
and the method with the query using the template that doesn’t work.
> Can you help me figure out why searchLdapForCeoUsingTemplate() is not working?
> Here’s LdapClient.java:
