如何设定JDBC DRIVER的路径然后动态加载

[fkpwolf]

我用
// URL u = new URL("file:/d:/JavaStuff/jdbc-driver/informix.jar");
// URLClassLoader ucl = new URLClassLoader(new URL[]{u});
// Class c = ucl.loadClass(driver);
怎么不行?

一样有错误啊:java.sql.SQLException: No suitable driver
必须把.jar加入到classpath中才会没有错误出现.

我查了下:
Driver driverd = (Driver)drvCls.newInstance();
Properties props = new Properties();
props.setProperty("user", cs.user);
props.setProperty("password", cs.password);
conn = driverd.connect(url, props);
主要是最后一句.

试试：
URL[] u={new File("d:/JavaStuff/jdbc-driver/informix.jar").toURL()};
ClassLoader cl = new URLClassLoader(u, getClass().getClassLoader());
Class c=cl.loadClass(driver);
