您好我正在尝试使用JDBC建立与Oracle的连接。
我在Win 7 x86上运行Oracle 10g R2 XE,Eclipse Java EE Juno和Java SE v1.7。我在WebContent / WEB-INF / lib中包含了class.12.jar和ojdbc5.jar,因为之前使用ojdbc.jar,它在连接数据库时出错。所以我完全不确定要包含哪个驱动程序。
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
在最后一行提供以下例外
java.lang.ArrayIndexOutOfBoundsException: 7

Sam做错了什么,或者我还在使用错误的驱动程序。我应该包括哪一个?
修改
我也尝试过网址:
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"
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:168)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:210)

at ConnectionManager.main(ConnectionManager.java:25)
我也尝试将驱动程序名称更改为:
String driverName = "oracle.jdbc.driver.OracleDriver";
没用。
并且同时使用ojdbc5.jar,ojdbc6.jar,但没有用。 :'(
答案 0 :(得分:0)
您的网址似乎有误。
您指的是ojdbc5.jar
,最好使用ojdbc6.jar
Jar可以在这个位置找到: -
$ORACLE_HOME/jdbc/lib/ojdbc6.jar
这样做: -
Connection conn = null;
String driverName = "oracle.jdbc.driver.OracleDriver";
OR
String driverName = "oracle.jdbc.OracleDriver";
String url = "jdbc:oracle:thin:@//localhost:1521/xe";
Class.forName(driverName);
conn = DriverManager.getConnection(url, "system", "mypassword");
