这方面的技术俺不懂,请教各位帮忙了
用jdbc连,资料很多的
一样的。faq 里看一下就知道了。
Connecting to an Oracle Database
This example uses an Oracle JDBC driver to connect to an Oracle database instance located at 128.0.0.0:1521 with an sid called mydatabase.
Connection connection = null;
try {
// Load the JDBC driver
String driverName = "oracle.jdbc.driver.OracleDriver";
Class.forName(driverName);
// Create a connection to the database
String serverName = "127.0.0.1";
String portNumber = "1521";
String sid = "mydatabase";
String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
String username = "username";
String password = "password";
connection = DriverManager.getConnection(url, username, password);
} catch (ClassNotFoundException e) {
// Could not find the database driver
} catch (SQLException e) {
// Could not connect to the database
}
Connecting to a MySQL Database
This example connects to a MySQL database using the MM JDBC driver for MySQL. You need to have an account in MySQL database to run this example. To create an account, you can connect to MySQL database on your platform as root, and run the following command:
mysql> GRANT ALL PRIVILEGES ON *.* TO username@localhost
IDENTIFIED BY password WITH GRANT OPTION;
Connection connection = null;
try {
// Load the JDBC driver
String driverName = "org.gjt.mm.mysql.Driver"; // MySQL MM JDBC driver
Class.forName(driverName);
// Create a connection to the database
String serverName = "localhost";
String mydatabase = "mydatabase";
String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url
String username = "username";
String password = "password";
connection = DriverManager.getConnection(url, username, password);
} catch (ClassNotFoundException e) {
// Could not find the database driver
} catch (SQLException e) {
// Could not connect to the database
}
Connecting to a SQLServer Database
This example connects to a SQLServer database using the NetDirect JDBC driver. For information about this driver, see e232 Getting JDBC Drivers for a Database.
Connection connection = null;
try {
String driverName = "com.jnetdirect.jsql.JSQLDriver"; // NetDirect JDBC driver
String serverName = "127.0.0.1";
String portNumber = "1433";
String mydatabase = serverName + ":" + portNumber;
String url = "jdbc:JSQLConnect://" + mydatabase; // a JDBC url
String username = "username";
String password = "password";
// Load the JDBC driver
Class.forName(driverName);
// Create a connection to the database
connection = DriverManager.getConnection(url, username, password);
} catch (ClassNotFoundException e) {
// Could not find the database driver
} catch (SQLException e) {
// Could not connect to the database
}
如果不在jb中,那么就直接放在你的java-home/jre/lib/ext/目录中就可以了
如果在jb中,那么加到项目中引用就可以了
我上边的帖子中有三种连接mysql\oracle\sqlserver,你一定没有仔细看。
我把sql放在下边。

一般的都行啦
