Jdbc java.lang.ArrayIndexOutOfBoundsException:连接到Oracle 10g XE时

您好，我正在尝试使用JDBC与Oracle建立连接

我在Win7 x86上运行Oracle 10g R2 XE、Eclipse Java EE Juno和Java SE v1.7。我已经在WebContent/WEB-INF/lib中包含了类.12.jar和类ojdbc5.jar，因为之前使用ojdbc.jar时，连接到数据库时出现错误。所以我很不确定我到底要包括哪个司机

我的代码是：

    Connection conn = null;
    String driverName = "oracle.jdbc.OracleDriver";
    String url = "jdbc:oracle:thin:@localhost:1521:xe";

    Class.forName(driverName);
    conn = DriverManager.getConnection(url, "system", "mypassword"); //exception occurs here

它在最后一行给出了以下异常

java.lang.ArrayIndexOutOfBoundsException: 7

at oracle.security.o3logon.C0.l(C0)

at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at ConnectionManager.getConnection(ConnectionManager.java:16)
at ConnectionManager.main(ConnectionManager.java:24)

它给了我以下的例外：

java.sql.SQLException: Io exception: Invalid connection string format, a valid format is: "host:port:sid"

没用

---

同时使用ojdbc5.jar和ojdbc6.jar，但没有任何用处：（

您的URL似乎有误

您所指的是

ojdbc5.jar

，最好使用

ojdbc6.jar

可以在以下位置找到Jar：-

$ORACLE_HOME/jdbc/lib/ojdbc6.jar

这样做：-

Connection conn = null;
String driverName = "oracle.jdbc.driver.OracleDriver";

或

事实上，我以前试过。它给我一个异常（我现在已经添加到原始问题中）说url格式无效，这就是我格式化上述url的原因。我用ojdbc6.jar尝试过这个，没有区别。请查看我在原始问题中添加的stacktrace，看看你是否能发现任何错误。请帮助。

$ORACLE_HOME/jdbc/lib/ojdbc6.jar

Connection conn = null;
String driverName = "oracle.jdbc.driver.OracleDriver";

String driverName = "oracle.jdbc.OracleDriver";
String url = "jdbc:oracle:thin:@//localhost:1521/xe";

Class.forName(driverName);
conn = DriverManager.getConnection(url, "system", "mypassword");
