信息发布界面
提供发布信息的交互界面调用 recordMessagejsp程序

连接数据库
通过调用 Java Bean连接 Oracle数据库
opDbjava
package ymbean; // java包
import javasql＊ ;
public class opDb {
public opDb() { }
public ResultSet executeQuery(String sql)
{
ResultSet rs = null;
Statement lstmt = null;
try { lstmt = connectdb();
rs = lstmtexecuteQuery(sql);
Systemoutprintln(“ executeQuery:”＋ sql);
} catch(SQLException ex) { return(null) }
return rs;
}
public String executeUpdate(String sql)
{
ResultSet rs = null;
Statement lstmt = null;
try {
lstmt = connectdb();
lstmtexecuteUpdate(sql);
Systemoutprintln(“ executeUpdate:”＋ sql);
lstmtexecuteUpdate(“ commit” );
}catch(SQLException ex) {}
return(“ executeUpdate ok” );
}
//连接数据库
public Statement connectdb()
{ Statement lstmt=null;
Connection conn=null;
final String connect_string=“ jdbc:oracle:thin:scott/tiger@::test” ;
final String driver_string=“ oraclejdbcdriver
OracleDriver” ;
Connection lconn;
try { ClassforName(driverstr);
lconn=DriverManagergetConnection(connectstr);
lstmt=lconncreateStatement();
} catch (Exception e) { return(null);}
return lstmt;
}
}//end opDbjava
