The first mistake hibernate program , adjusting for a day .

Error message as follows :

------ Solution ---------------------------- ----------------
built data sources, configure hibernate configuration file when directly elected configured data source on the line.
------ Solution ---------------------------------------- ----
suggest you write a JDBC test the following classes in the project there , see if you can connect successfully.
online there are many such examples , what is the code I've used before , you may need to do some modification to use .

import java.sql.Connection;
  import java.sql.DriverManager;
  import java.sql.ResultSet;
  import java.sql.SQLException;
  import java.sql.Statement;
  
  public class cn1 {
  	public static void main(String[] args) {
  
  		Connection conn = null;
  		Statement stmt = null;
  		ResultSet rs = null;
  
  		try {
  			//The drive is specific for Oracle
  			Class.forName("oracle.jdbc.driver.OracleDriver");
  		} catch (java.lang.ClassNotFoundException e) {
  			System.err.println("mydb(): " + e.getMessage());
  		}
  
  		try {
  			conn = DriverManager.getConnection(
  					"jdbc:oracle:thin:@usplgmdb003.iweb.gm.com:1521:gwh21", "gmu", "dragon");
  		} catch (SQLException ex) {
  			System.err.println("conn:" + ex.getMessage());
  		}
  
  		if (conn != null)
  			System.out.println("connection successful");
  		else
  			System.out.println("connection failure");
  
  		try {
  			stmt = conn.createStatement();
  		} catch (SQLException ex) {
  			System.err.println("createStatement();" + ex.getMessage());
  		}
  
  		try {
  			rs = stmt.executeQuery("select count(*) from COLLEGE");
  		} catch (SQLException ex) {
  			System.err.println("stmt.excuteQuery();" + ex.getMessage());
  		}
  
  		try {
  			while (rs.next()) {
  				System.out.println("Row number: " + rs.getInt(1));
  			}
  		} catch (SQLException ex) {
  			System.err.println("A ERROR is failure" + ex.getMessage());
  		}
  	}
  
  	public static void printClassName(Object obj) {
  		System.out.println("The class of " + obj + " is "
  				+ obj.getClass().getName());
  	}
  
  }

sorry , the landlord is already imported , but the program can not find the newspaper !

landlord can build a data source in eclipse , hibernate configuration file after it is generated . Directly with the data source has been built .

myeclipse I just opened again , a bomb suddenly pop out . Follows
this project is not a myeclipse hibernate project. assuming hibernate 3 capability

I remember the first time will be able to write directly to hibernate when running , but this time a variety of problems.
My system is 64-bit win7 Ultimate installed , JDK is 1.7.0_45, myeclipse10 was cracked version . hibernate is 4.2.7
these things affect you ?

link JDBC can be successful , but fails to connect with hibernate on

I have solved this problem , specific solutions means forget, anyway, is the East West changed changed , the memory is changed after completing have changed back in
But now actually be able to succeed.
Thank you great God
