Description

Connecting with JXplorer leads to the NPE in LdapDN as I reported on the list earlier. Please see the complete log.

Comments

[Jörg Henne]

After fixing LdapResult, not LdapDN as I erroneously said (please see patch, It'll make the code more robust as StringBuffer.append(Object) can deal with null-references), I get an exception similar to the one I reported yesterday (see attached log).

[Jörg Henne]

Use StringBuffer.append(Object) instead of StringBuffer.append(Object.toString()) to prevent NPEs.

Ok, so I found some time to look into this problem. It seems like the optimized version did no longer supply the "subschemasubentry" attribute to JXplorer when being asked for it. This was due to the DefaultPartitionNexus only returning results when being asked for "*", "1.1" or "+" but not when being asked for specific attributes.

The attached patch fixes the problem. However, I don't really understand the implications of it. Furthermore, it is likely to cause deoptimization ;-)

[Ersin Er]

We need to investigate the disappearance of subscemaSubentry attribute. Anyone knows why it happened? Was it intended?

[Jörg Henne]

Version #423997 introduced a new way to handle the special attributes "1.1", "*" and "+". With this change, the DefaultPartitionNexus stopped providing client-requested attributes, If neither of the above mentioned special attributes were requested.

I have fixed the toString problem (I don't let the default toString to print "(null)", I return an empty String instead)

The second pb is for Alex, I think :)

[Emmanuel Lecharny]

One more for Alex !

[Alex Karasulu]

This still happening ?

[Jörg Henne]

The problems I initially reported should be fixed by the various patches applied within the last days/weeks. However, I can't verify this, since with the current trunk I can't even start ds:

Additionally, "mvn -Dintegration -fn test" fails for several sub-projects.

[Emmanuel Lecharny]

Are you using trunks, or branches/apacheds/1.0-trunks?

In any case, do you do a mvn clean before doing a mvn install and a mvn -Dintegration test ?

[Jörg Henne]

*cough*
Sorry, my fault: mvn clean did the trick.
However, connecting using JXplorer still doesn't work, since the schema is not served. Please see the attached fix-for-jxplorer-problem.patch.

[Alex Karasulu]

Applied Jorg's patch to 1.0 in 431981 and to 1.1 in 431983.
