c3p0 配置文件 存放路径
c3p0怎么加载配置文件？不用hibernate和spring,怎么从配文件设置连接池？j2se程序.

不是web程序 大家注意啦
就是一个普通的可以应用的main程序
[解决办法]
配置文件格式你可以自己定义，并解析不难。c3p0 api可见下面例子，你要下载c3p0的jar到你工程中；解析好格式后把属性设置给c3p0的ComboPooledDatasource的对象就OK了

public static void main(String[] args) throws Exception {
        ComboPooledDataSource cpds = new ComboPooledDataSource();
        cpds.setDriverClass("oracle.jdbc.OracleDriver");
        cpds.setJdbcUrl("jdbc:oracle:thin:@localhost:1521:orcl");
        cpds.setUser("mmc");
        cpds.setPassword("mmc");
        cpds.setMinPoolSize(5);
        cpds.setMaxStatements(50);
        cpds.setAcquireIncrement(5);
        cpds.setMaxPoolSize(20);

        Connection con = cpds.getConnection();
        try {
            Statement stmt = con.createStatement();
            con.setAutoCommit(true);
            stmt.executeUpdate("CREATE TABLE tempTab (id VARCHAR(32) ,name VARCHAR(32),age NUMBER,score NUMBER)");
            stmt.executeUpdate("delete from tempTab");
            stmt.executeUpdate("INSERT INTO tempTab VALUES ('075','joyce',22,90)");
            stmt.executeUpdate("INSERT INTO tempTab VALUES ('071','LILY',23,80)");
            stmt.executeUpdate("INSERT INTO tempTab VALUES ('072','MOMO',22,88)");

            String sql = "SELECT C.id, C.name from tempTab c"; 
 
            ResultSet rs = stmt.executeQuery(sql);
            while (rs.next()) {
                System.out.print(rs.getString(1) + " ");
                System.out.println(rs.getString(2));
            }
            rs.close();

            stmt.executeUpdate("drop table tempTab");
            stmt.close();
        } finally {
            con.close();
            cpds.close();
        }
    }
