java列出所有lotus notes数据库

Question

我试图用Java创建一个lotus notes客户机。现在，我在列出所有用户定义的数据库时遇到了一个问题。我想做的是

// testing purpose
private void printAllDb() throws NotesException
{
    DbDirectory dir = session.getDbDirectory(host);
    String server = dir.getName();
    if(server.equals(""))
    {
        server = "Local";
    }

    System.out.println("database direcory list on server (" + server + ")");
    Database db = dir.getFirstDatabase(DbDirectory.DATABASE);

    do
    {
        System.out.println("file name: " + db.getFileName().toUpperCase() + " - " + db.getTitle());

    } while((db = dir.getNextDatabase()) != null);

}

但是，程序将抛出异常：
