[jira] Created: (DIRSERVER-952) NPE when using createSubcontext()
with embedded server
NPE when using createSubcontext() with embedded server
------------------------------------------------------
Key: DIRSERVER-952
URL: https://issues.apache.org/jira/browse/DIRSERVER-952
Project: Directory ApacheDS
Issue Type: Bug
Components: core
Affects Versions: 1.0.2
Environment: Windows 2003, JDK 1.5
Reporter: Simon Temple
Fix For: 1.0.2
We've found a problem with DS 1.0.2. This problem only exists when running with DS embedded in the same VM.
Running the same code remotely (outside of DS VM) works fine.
Example code:
....
Attributes attrs = new BasicAttributes();
attrs.put("objectClass", "organizationalUnit");
attrs.put("description", "Test OU");
DirContext subContext = context.createSubcontext("ou=Test", attrs);
Exception from createSubcontext():
Caused by: java.lang.NullPointerException
at org.apache.directory.shared.ldap.util.AttributeUtils.containsValueCaseIgnore(AttributeUtils.java:309)
at org.apache.directory.server.core.schema.SchemaService.assertAllAttributesAllowed(SchemaService.java:1806)
at org.apache.directory.server.core.schema.SchemaService.check(SchemaService.java:1624)
at org.apache.directory.server.core.schema.SchemaService.add(SchemaService.java:1636)
at org.apache.directory.server.core.interceptor.InterceptorChain$Entry$1.add(InterceptorChain.java:1181)
... 130 more
If you change the BasicAttributes() constructor call to:
Attributes attrs = new BasicAttributes( true );
it works fine.

[jira] Commented: (DIRSERVER-952) NPE when using createSubcontext()

Emmanuel Lecharny commented on DIRSERVER-952:
---------------------------------------------
Beside the fact we have a NPE, this behaviour is expected as the BasicAttributes() has been created as caseSensitive in the caller code.
What happens is that you created the attribute using "objectClass" when we are looking for "objectclass" in the code ( we do attr.getAttribute( "objectclass" ) ). We have two options here :
- throwing an explicit exception instead of a NPE
- writing some costly code to iterate through all the attributes, like :
...
if ( objectClass == null )
{
NamingEnumeration ids = attributes.getIDs();
while ( ids.hasMoreElements() )
{
String id = (String)ids.nextElement();
if ( "objectclass".compareToIgnoreCase( id ) == 0 )
{
objectClass = attributes.get( id );
break;
}
}
if ( objectClass == null )
{
throw new NamingException( "No ObjectClass attribute in the entry" );
}
}
...
Even if I personnaly hate JNDI for allowing users to create case sensitive BasicAttributes(), I think we should protect the server from it because all our users will do this mistake at least once (and I did this mistake so many times ... !). So I will implement this loop, and I will also do it in 1.5 version, because we have the very same error.
