invalid SQL url specified

[Guest_imported]

Dear Pro.:
i tried to test my driver version, and the error message is:

Exception in thread "main" java.sql.SQLException: Invalid Oracle URL specified
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:168)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:210)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:273)

at java.sql.DriverManager.getConnection(DriverManager.java:512)
at java.sql.DriverManager.getConnection(DriverManager.java:171)
at Test.main(Test.java:6)

i used thin driver, my database is wendb, user is wen, pwd is wen
below is my tnsnames.ora data:

# TNSNAMES.ORA Network Configuration File: D:\oracle\ora81\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

WENDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = wenkai)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = WENDB)
)
)

INST1_HTTP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = wenkai)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = SHARED)
(SERVICE_NAME = WENDB)
(PRESENTATION =

http://admin)

)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

what would be the correct URL:
Connection conn=DriverManager.getConnection ("jdbcracle:thin?:?:?","wen","wen"

thank you...

jdbcracle:thin<hostname>:<port>:<dbname>,&quot;uname&quot;,&quot;passwd&quot;
Is the correct form of URL.
I use the one above to connect to my database, all the blanks are filled in of course
