各种驱动的连接方法：
1. MySQL(http://www.mysql.com) mysql-connector-java-2.0.14-bin.jar ;
  Class.forName( "org.gjt.mm.mysql.Driver" );
  cn = DriverManager.getConnection( "jdbc:mysql://MyDbComputerNameOrIP:3306/myDatabaseName", sUsr, sPwd );
2. PostgreSQL(http://www.de.postgresql.org) pgjdbc2.jar ;
  Class.forName( "org.postgresql.Driver" );
  cn = DriverManager.getConnection( "jdbc:postgresql://MyDbComputerNameOrIP/myDatabaseName", sUsr, sPwd );
3. Oracle(http://www.oracle.com/ip/deploy/database/oracle9i/) classes12.zip ;
  Class.forName( "oracle.jdbc.driver.OracleDriver" );
  cn = DriverManager.getConnection( "jdbc:oracle:thin:MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd );
4. Sybase(http://jtds.sourceforge.net) jconn2.jar ;
  Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" );
  cn = DriverManager.getConnection( "jdbc:sybase:Tds:MyDbComputerNameOrIP:2638", sUsr, sPwd );
  //(Default-Username/Password: "dba"/"sql")
5. Microsoft SQLServer(http://jtds.sourceforge.net) ;
  Class.forName( "net.sourceforge.jtds.jdbc.Driver" );
  cn = DriverManager.getConnection( "jdbc:jtds:sqlserver://MyDbComputerNameOrIP:1433/master", sUsr, sPwd );
6. Microsoft SQLServer(http://www.microsoft.com) ;
  Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
  cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://MyDbComputerNameOrIP:1433;databaseName=master", sUsr, sPwd );
7. ODBC
  Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
  Connection cn = DriverManager.getConnection( "jdbc:dbc:" + sDsn, sUsr, sPwd );
8.DB2 Class.forName("com.ibm.db2.jdbc.net.DB2Driver");
  String url="jdbc:db2://192.9.200.108:6789/SAMPLE"
  cn = DriverManager.getConnection( url, sUsr, sPwd );
9.access由于access并不是作为一项服务运行，所以url的方法对他不适用。access可以通过odbc，也可以通过服务器映射路径的形式 找到.mdb文件,参见http://rmijdbc.objectweb.org/Access/access.html

这对初学者还是很好的帮助。
