|
+--netscape.ldap.LDAPException
Indicates that an error has occurred. An LDAPException
can result from physical problems (such as network errors) as well as
problems with LDAP operations (for example, if the LDAP add operation
fails because of duplicate entry).
Most errors that occur throw this type of exception. In order to determine
the cause of the error, you can call the getLDAPResultCode()
method to get the specific result code and compare this code against
the result codes defined as fields in this class. (For example, if
the result code matches the value of the field
LDAPException.TIME_LIMIT_EXCEEDED, the time limit passed
before the search operation could be completed.)
This exception includes methods for getting an error message that
corresponds to the LDAP result code (for example, "Timelimit exceeded"
for LDAPException.TIME_LIMIT_EXCEEDED). These error
messages are specified in the following files:
netscape/ldap/errors/ErrorCodes_locale_string.propswhere locale_string is the name of the locale that includes the language and country, but not the variant.
For example:
netscape/ldap/errors/ErrorCodes_en_US.propsThe LDAP Java classes get this locale name by calling the
java.util.Locale.toString method for the specified
locale and ignoring the variant. If no locale is specified, the
LDAP Java classes use the java.util.Locale.getDefault
method to get the locale of the local host system.
In order to get error messages for different locales, you need to
provide files containing the error messages for those locales.
The files should be located in the netscape/ldap/errors
directory and should use the naming convention specified above.
The following is a list of LDAP result codes:
