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

Question

您好，我正在尝试与JDBC建立Oracle连接。

我在Win 7 x86上运行，运行Oracle 10g R2 XE，Eclipse Java EE Juno和Java SE v1.7。自从之前使用 ojdbc 以来，我已经在 WebContent/WEB-INF/lib 中包含 class.12.jar 和 ojdbc5.jar .jar它在连接到数据库时出错。所以我不确定我到底要包括哪个驱动程序。

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

它在最后一行给出以下异常

java.lang.ArrayIndexOutOfBoundsException: 7

山姆做错了什么，或者我还是用错了司机。我应该包括哪一个？

编辑

我也试过网址:

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

它给了我以下例外：

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

我还尝试将驱动程序名称改为:

String driverName = "oracle.jdbc.driver.OracleDriver";

没有用。

并且同时使用ojdbc5.jar，ojdbc6.jar，但没有用。:'(

Answer 1

您的网址似乎有误。

如果您引用的是< code>ojdbc5.jar，您最好使用< code>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";

运筹学

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

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