DriverManager.getConnection出错(20分)

DriverManager.getConnection("jdbcracle:thinlocalhost:1521:scss")
java.sql.SQLException: 调用中无效的参数
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)

DriverManager.getConnection("jdbcracle:thinlocalhost:1521:scss")
参数个数不对，需要写用户名和密码
DriverManager.getConnection("jdbcracle:thinlocalhost:1521:scss","username","password")

java.sql.DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
注册了数据库驱动没有？
to only you:
在java.sql.DriverManager有这个函数
static ConnectiongetConnection(String url) Attempts to establish a connection to the given database URL.

to clever_boy_2000
谢谢！可是ConnectiongetConnection(String url) 是把用户名和密码写到url中的
象DriverManager.getConnection("jdbcracle:thinlocalhost:1521:scss;user=asdfasdf;password=asdfasf")

only you：同意你

thanks a lot
