Exceptions

To simplify resiliency configuration, it is important to chain exceptions in your connector implementation using namingException.initCause(origEx) when wrapping exceptions thrown by native APIs. This allows you to configure retrying with a minimal set of base error messages configured (for example, chained cause may be a socket error).

For example, consider the following code snippet:

try
{
…native API calls…
}
catch (NativeException e)
{
final LdapNamingException   ne;
ne = new LdapNamingException(msg,
ResultCodeEnum.INVALID_CREDENTIALS);
ne.initCause(e);
throw ne;
}
