Hello,
I get the following exception from my ApacheDS server log when the Weblogic LDAP authenticator client makes a query.

I guess that the "{0}" text does not get substituted, because the value is null. that is:
System.out.println(java.text.MessageFormat.format("ERR_04274 Cant find an OID for the name {0}", (String) null)); // ERR_04274 Cant find an OID for the name null
System.out.println(java.text.MessageFormat.format("ERR_04274 Cant find an OID for the name {0}", (String[]) null)); // ERR_04274 Cant find an OID for the name {0}
./org/apache/directory/shared/ldap/schema/registries/DefaultSchemaObjectRegistry.java
public String getOidByName( String name ) throws LdapException
{
T schemaObject = byName.get( name );
// ok this name is not for a schema object in the registry
if ( schemaObject == null )
{
343: throw new LdapException( I18n.err( I18n.ERR_04274, name ) );
and the values is
./i18n/src/main/java/org/apache/directory/server/i18n/I18n.java
public static String err( String err, Object... args ) {
789: return err + " " + MessageFormat.format( errBundle.getString( err ), args );
}
the "name" comes from:
./core/src/main/java/org/apache/directory/server/core/normalization/FilterNormalizingVisitor.java
private ExprNode visitExtensibleNode( ExtensibleNode node ) throws LdapException {
313: node.setAttribute( schemaManager.getAttributeTypeRegistry().getOidByName( node.getAttribute() ) );
return node;
}
which means that at some point a LeafNode with a null attribute is created.
./org/apache/directory/shared/ldap/filter/LeafNode.java
public class LeafNode extends AbstractExprNode
{
/** attribute on which this leaf is based */
private String attribute;
...
}
(unfortunately i cannot reproduce the problem with a simple unit case,
i have a configuration problem, either at ApacheDS or at Weblogic, i am still finding out)
I guess that LeafNode with a null attribute should not be allowed. is that correct?
should a null test be added here? or even before?
the problem with the current code is that the exception is thrown to late to understand the source of the problem.
I guess some more test or log should be added, instead of receiving the poor message "ERR_04274 Cant find an OID for the name {0}".
