Could not open Notes session之解－Jemmy Walker

　　使用Java去操作Lotus Notes，大都需要import兩個Jar：Notes.jar與NCSO.jar。只用Notes.jar還需安裝Notes Client才能與Server連，而NCSO.jar則是透過IBM制定的CORBA協議DIIOP連接到Domino Server的。

　　由IBM提供Sample連接，老是出現以下Exception：

Caused by: NotesException: Could not open Notes session: org.omg.CORBA.COMM_FAILURE: java.net.ConnectException: Connection refused: connect Host: 127.0.0.1 Port: 63148 vmcid: 0x0 minor code: 1 completed: No
    at lotus.domino.cso.Session.initSession(Unknown Source)
    at lotus.domino.cso.Session.<init>(Unknown Source)
    at lotus.domino.cso.Session.createSession(Unknown Source)
    at lotus.domino.NotesFactory.createSessionUP(Unknown Source)
    at lotus.domino.NotesFactory.createSession(Unknown Source)

　　而由Sample程式Create Session來看，明明不是指定連Local Host。

Session s = NotesFactory.createSession("1.2.3.4:63148", "notesadmin", "password");
Database db = s.getDatabase("NOTES01", "DEMO.NSF");

　　經過同事Sam大力支援，在IBM官方文件看到如下：http://www.ibm.com/developerworks/lotus/library/ls-Java_access_pt1/

原來就是Domino Server上把DIIOP的Host name/Adress設成127.0.0.1之故。
