Answer 1

可能不是包的问题 你先用pl/sql链接试试 如果不行的话 吧下面的代码考到相应的文件中:
sqlnet.ora:
# sqlnet.ora Network Configuration File: F:\oracle\product\10.1.0\Db_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

tnsnames.ora:
# tnsnames.ora Network Configuration File: F:\oracle\product\10.1.0\Db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

listener.ora:
# listener.ora Network Configuration File: F:\oracle\product\10.1.0\Db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\oracle\product\10.1.0\db_1)
(PROGRAM = extproc)
)
)

(SID_DESC =
(GLOBAL_DBNAME = ORACLE)
(ORACLE_HOME = F:\oracle\product\10.1.0\db_1)
(SID_NAME = orcl)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)
)

里面的路径自己改下.

SID不正确，跟包没关系

Answer 3

这个和包没有关系，检查你需要调用的数据库名是否在制定机器上存在

Answer 4

oracle的驱动jar包，你的sid写错了~看：http://qingfengjushi1.javaeye.com/blog/698519
