StartTlsRequest/StartTlsResponse are used to establish a TLS connection over the existing LDAP connection associated with the JNDI context on which extendedOperation() is invoked. Typically, a JNDI program uses these classes as follows.

 import javax.naming.ldap.*;
 // Open an LDAP association
 LdapContext ctx = new InitialLdapContext();
 // Perform a StartTLS extended operation
 StartTlsResponse tls =
 (StartTlsResponse) ctx.extendedOperation(new StartTlsRequest());
 // Open a TLS connection (over the existing LDAP association) and get details
 // of the negotiated TLS session: cipher suite, peer certificate, etc.
 SSLSession session = tls.negotiate();
 // ... use ctx to perform protected LDAP operations
 // Close the TLS connection (revert back to the underlying LDAP association)
 tls.close();
 // ... use ctx to perform unprotected LDAP operations
 // Close the LDAP association
 ctx.close;
 

The result must be a concrete subclass of StartTlsResponse and must have a public zero-argument constructor.

The result must be a concrete subclass of StartTlsResponse and must have a public zero-argument constructor.

This method locates the implementation class by locating configuration files that have the name:

META-INF/services/javax.naming.ldap.StartTlsResponse

Each configuration file should contain a list of fully-qualified class names, one per line. Space and tab characters surrounding each name, as well as blank lines, are ignored. The comment character is '#' (0x23); on each line all characters following the first comment character are ignored. The file must be encoded in UTF-8.

This method will return an instance of the first implementation class that it is able to load and instantiate successfully from the list of class names collected from the configuration files. This method uses the calling thread's context classloader to find the configuration files and to load the implementation class.

If no class can be found in this way, this method will use an implementation-specific way to locate an implementation. If none is found, a NamingException is thrown.
Parameters:
  id - The object identifier of the extended response.Its value must be "1.3.6.1.4.1.1466.20037" or null.Both values are equivalent.
Parameters:
  berValue - The possibly null ASN.1 BER encoded value of theextended response. This is the raw BER bytesincluding the tag and length of the response value.It does not include the response OID.Its value is ignored because a Start TLS responseis not expected to contain any response value.
Parameters:
  offset - The starting position in berValue of the bytes to use.Its value is ignored because a Start TLS responseis not expected to contain any response value.
Parameters:
  length - The number of bytes in berValue to use.Its value is ignored because a Start TLS responseis not expected to contain any response value. The StartTLS extended response object.
exception:
  NamingException - If a naming exception was encounteredwhile creating the StartTLS extended response object.
