SQL Server 2000 Driver for JDBC Service Pack 3 安装测试方法

SQL Server 2000 Driver for JDBC Service Pack 3 安装测试方法

1.安装:SQL Server 2000 Driver for JDBC Service Pack 3

下载安装JDBC SP3

//jb51.net/softs/234108.html

里面的安装包

按照提示安装可以了.成功后有三个文件要使用:

c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/msbase.jar

c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/msutil.jar

c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/mssqlserver.jar

2.测试代码

新建类文件Connect.java.

package test;

import java.*;

import java.sql.Driver;

public class Connect{

private java.sql.Connection con = null;

private final String url = "jdbc:microsoft:sqlserver://";

private final String serverName= "localhost";

private final String portNumber = "1433";

private final String databaseName= "DBtest";

private final String userName = "sa";

private final String password = "123456";

// Informs the driver to use server a side-cursor,

// which permits more than one active statement

// on a connection.

private final String selectMethod = "cursor";

// Constructor

public Connect(){}

private String getConnectionUrl(){

return url+serverName+":"+portNumber+";databaseName="+databaseName+";selectMethod="+selectMethod+";";

}

private java.sql.Connection getConnection(){

try{

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");

con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password);

if(con!=null) System.out.println("Connection Successful!");

}catch(Exception e){

e.printStackTrace();

System.out.println("Error Trace in getConnection() : " + e.getMessage());

}

return con;

}

/*

Display the driver properties, database details

*/

eNXAjthCe public void displayDbProperties(){

java.sql.DatabaseMetaData dm = null;

java.sql.ResultSet rs = null;

try{

con= this.getConnection();

if(con!=null){

dm = con.getMetaData();

System.out.println("Driver Information");

System.out.println("/tDriver Name: "+ dm.getDriverName());

System.out.println("/tDriver Version: "+ dm.getDriverVersion ());

System.out.println("/nDatabase Information ");

System.out.println("/tDatabase Name: "+ dm.getDatabaseProductName());

System.out.println("/tDatabase Version: "+ dm.getDatabaseProductVersion());

System.out.println("Avalilable Catalogs ");

rs = dm.getCatalogs();

while(rs.next()){

System.out.println("/tcatalog: "+ rs.getString(1));

}

rs.close();

rs = null;

closeConnection();

}else System.out.println("Error: No active Connection");

}catch(Exception e){

e.printStackTrace();

}

dm=null;

}

private void closeConnection(){

try{

if(con!=null)

con.close();

con=null;

}catch(Exception e){

e.printStackTrace();

}

}

public static void main(String[] args) throws Exception

{

Connect myDbTest = new Connect();

myDbTest.displayDbProperties();

}

}

成功后控制台输出:

Connection Successful!

3.问题:

在测试中控制台老输出下面的错误!

找资料找了很久.都说把jdbc安装后的三个jar文件的路径放进环境变量里可以了但我试了不行的!

java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver

.........

Error Trace in getConnection() : com.microsoft.jdbc.sqlserver.SQLServerDriver

Error: No active Connection

请教了别人才找到办法:

包资源管理器-->包名右键"构建路径"-->配置构建路径-->java构建路径-->库-->添加外部JAR

把那三个JAR选择进去就可以了.

添加后三个JDBC文件就有了.
