No, you don't get it. The public API isn't sufficient to trigger batching
(actually it might but not in a very controllable way). You will have to
do something like:

package jcifs.smb;

public class BatchingTests extends SmbFile {

	public void createAndReadAndClose() {
		SmbComClose req3 = new SmbComClose(...);
		SmbComCloseResponse resp3 = new SmbComCloseResponse(...);

		SmbComReadAndX req2 = new SmbComRead(...., req3);
		SmbComReadAndXResponse resp2 = new SmbComReadAnxDRespons(...);

		SmbComNTCreateAndX req1 = new SmbComNTCreateAndX(..., req2);
		SmbComNTCreateAndX resp1 = new SmbComNTCreateAndXResponse(...);

		send(req1, resp1);
	}
}

This is highly trivialized obviously. You would have to look at the code
and get an idea for how the internal API is used.
