Subject [jira] [Updated] (DBUTILS-96) dynamic load jdbc jars use Dbutils,it say No suitable driver found for jdbc
Date Thu, 26 Jul 2012 01:40:33 GMT

     [ https://issues.apache.org/jira/browse/DBUTILS-96?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

yuyf updated DBUTILS-96:
------------------------

    Description: 
By this way(use Dbutil get connect),it will say:No suitable driver found for jdbc:mysql://127.0.0.1:3306/xxx

urls = new URL[1];
urls[0] = new File("d:\mysql_connector_5.1.15_bin.jar").toURL();
URLClassLoader urlClassLoader= new URLClassLoader(urls,ClassLoader.getSystemClassLoader())
	
DbUtils.loadDriver(urlClassLoader,driver);
Properties conProps = new Properties(); 
conProps.put("user", user); 
conProps.put("password", pwd); 
conProps.put("defaultRowPrefetch", "20"); 
scanedConnection = DriverManager.getConnection(url, conProps);


but by this way (use jdbc's api get connect),it's ok

try {
URL jdbcDriverURL = new File("d:\\mysql_connector_5.1.15_bin.jar").toURL();
URL[] urls = new URL[1];
urls[0] = jdbcDriverURL;
URLClassLoader urlclassLoader = new URLClassLoader(urls,ClassLoader.getSystemClassLoader());
try {
java.sql.Driver driverd = (java.sql.Driver) urlclassLoader.loadClass(driver).newInstance();
System.out.println(driverd.toString());
Properties props = new Properties();
props.setProperty("user", theUser);
props.setProperty("password", thePw);
try {
c = driverd.connect(dbUrl, props);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}//

} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}




is this a bug or my useing falut?
