在Win2000下开发JSP，怎样直接用JDBC而不用连接桥？？？哪们高手知道？

[szabo]

哪位高人知道怎么做？请指教~~~~~~~~~~~~..

[xiaoyuzi]

Class.forName( "com.mysql.jdbc.Driver" );
Connection con =
DriverManager.getConnection("jdbc:mysql://localhost:3306/scurity","user","pwd");

[xiaoyuzi]

这是mysql的,其它的改一下驱动和url就可以了

1. 下载你需要的database的jdbc driver
2. 部署到合适的路径下
3. 在程序中加入以下语句：

常用数据库JDBC连接写法 zlyperson（原作）

关键字 JDBC Sybase MySQL SQLServer PostgreSQL Oracle ODBC DB2



1. MySQL(http://www.mysql.com)mm.mysql-2.0.2-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:odbc:" + sDsn, sUsr, sPwd );

8.DB2(新添加)
Class.forName("com.ibm.db2.jdbc.net.DB2Driver");
String url="jdbc:db2://192.9.200.108:6789/SAMPLE"
cn = DriverManager.getConnection( url, sUsr, sPwd );

你连接的什么数据库?

[seaman0916]

给你个连接数据库的Javabean,默认是 MySQL的驱动,可以改!

/*
* DBconn.java
*/
package dataBean;

import java.sql.*;
public class DBconn
{
String dbDriver="org.gjt.mm.mysql.Driver";
String conStr="jdbc:mysql://localhost:3306/3dsoft";
String myUser="root";
String myPassword="";
Connection con = null;
ResultSet rs = null;
public DBconn()
{
try
{
Class.forName(dbDriver);
}
catch(java.lang.ClassNotFoundException e)
{
System.err.println("DBconn (): " + e.getMessage());
}
}

public String getDbDriver()
{
return dbDriver;
}
public void setDbDriver(String dbDriver)
{
this.dbDriver=dbDriver;
}
public String getConStr()
{
return conStr;
}
public void setConStr(String conStr )
{
this.conStr = conStr ;
}
public String getMyUser()
{
return myUser ;
}
public void setMyUser(String myUser )
{
this. myUser= myUser ;
}
public String getMyPassword()
{
return myPassword ;
}
public void setMyPassword(String myPassword )
{
this.myPassword = myPassword ;
}
public ResultSet executeQuery(String sql) throws SQLException, Exception
{
rs = null;
try
{
con = DriverManager.getConnection(conStr,myUser,myPassword);
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery(sql);
}
catch(SQLException ex)
{
System.err.println("executeQuery:"+ex.getMessage());
return null;
}
catch(Exception e)
{
System.err.println("executeQuery:"+e.getMessage());
return null;
}
return rs;
}

public int executeUpdate(String sql)
{
int n=0;
try
{
con = DriverManager.getConnection(conStr,myUser,myPassword);
Statement stmt = con.createStatement();
n=stmt.executeUpdate(sql);
}
catch(SQLException ex)
{
System.err.println("executeUpdate:"+ex.getMessage());
return 0;
}
catch(Exception e)
{
System.err.println("executeQuery:"+e.getMessage());
return 0;
}
return n;
}
}

我装了啊，要不然怎么能连接上数据库呢？

[szabo]

我用的是Jdeveloper：建立连接可以查看到数据库，但是为什么运行JSP却说：
DriverManagerDataSource driver 'com.microsoft.jdbc.sqlserver.SQLServerDriver' not found

[mashaw]

是不是jdbc驱动没装

[szabo]

会不会是驱动程序有错呢？？？？？？？？？？


我在微软的站上下的，网站上说有6.9M，可是我下载下来才2M，微软的SQL server2000 的JDBC驱动程序会不会有错啊？？？？？？
