Insert the ServantLocator into the given Any.

Parameters:

any - the Any to insert into.

Returns:

narrowed instance.

Throws:

BAD_PARAM - if the passed object is not a ServantLocator.

unchecked_narrow

public static ServantLocator unchecked_narrow(Object obj)

Narrow the given object to the ServantLocator. For the objects that are always local, this operation does not differ from the ordinary narrow(org.omg.CORBA.Object) (ClassCastException will be thrown if narrowing something different). See OMG issue 4158.

1.5

read

public static ServantLocator read(InputStream input)

This should read the servant locator, but it cannot be transferred this way as its operations cannot be remote. The operations cannot be remote because one of the method parameters, POA, is required to be always a local object (both by 1.5 API and 3.0.3 OMG).

Throws:

MARSHAL, - always.

write

public static void write(OutputStream output,
         ServantLocator value)

This should write the servant activator, but it cannot be transferred this way as its operations cannot be remote. The operations cannot be remote because one of the method parameters, POA, is required to be always a local object (both by 1.5 API and 3.0.3 OMG).

Throws:

MARSHAL, - always.
