Emmanuel Lecharny commented on DIRAPI-320:
------------------------------------------
Hi,
that sounds like a nice workaround !
Yes, 'standard comparator' means {{ComparableComparator}} :
{code:java}
...
try
{
// Gets the associated Comparator
ldapComparator = registries.getComparatorRegistry().lookup(
matchingRule.getOid() );
}
catch ( LdapException ne )
{
// Default to a catch all comparator
ldapComparator = new ComparableComparator(
matchingRule.getOid() );
}
...
{code}
The {{RegexSyntaxChecker}} is not used atm, it was meant as an mean to extend
the schema.
Also worth noting that you still can use the {{Compare}} LDAP request when you
don't know how to do the work on the client. It's important to realize that it
implies a request to be sent to the server, but at least you won't have any
schema issue.
> ClassCastException on Objects.equals(Value,Value) for userPassword attribute
> ----------------------------------------------------------------------------
>
> Key: DIRAPI-320
> URL: https://issues.apache.org/jira/browse/DIRAPI-320
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 2.0.0.AM2
> Reporter: Pavel Zlámal
> Priority: Minor
>
> When I use _JarLdifSchemaLoader_ it seems to load _userPassword_ attribute
> type with different Comparator than when I load it from LDAP connection
> (openLDAP in my case).
> Then If I call:
> {code:java}
> Objects.equals(val, attribute.get())
> {code}
> to check if value passed to my method is the first in the attribute, I get
> _ClassCastException_, since it tries to pass _String_ (normalized value) to
> the _ByteArrayComparator._
> When I use Schema only loaded from connection, then it works, since it uses
> _ComparableComparator._
> {code:java}
> java.lang.ClassCastException: java.lang.String cannot be cast to [B
> at
> org.apache.directory.api.ldap.model.schema.comparators.ByteArrayComparator.compare(ByteArrayComparator.java:32)
> at org.apache.directory.api.ldap.model.entry.Value.equals(Value.java:1389)
> at java.util.Objects.equals(Objects.java:59)
> {code}
> So there is probably bug in schema ldif included in JAR or in equals()
> implementation of Value.
