2.采用weblogic的jdbc连接oracle
// 建立数据库的连接
// package com.yourCompany.yourApp;
package db_beans;
import javax.sql.DataSource;
import javax.naming.*;
import java.lang.*;
import java.sql.*;
import java.io.*;
import java.util.*;
public class connect_db{
public Connection con = null;
public ResultSet ret=null;
public Statement stmt=null;

//此连接为采用weblogic的jdbc直连接
public connect_db(){
try{
Properties props = new Properties();
props.put("user","cygs");
props.put("password","cygs");
props.put("server","study");
try{
Driver myDriver = (Driver) Class.forName("weblogic.jdbc.oci.Driver").newInstance();
con = myDriver.connect("jdbc:weblogic:oracle", props);
}catch(Exception e){
System.out.println(e.getMessage()+e.toString());
}
}catch(Exception ex){
ex.printStackTrace();
System.out.print(ex.toString());
return;
}
}

//执行select语句,并返回结果集
public ResultSet execsql(String sql){
try {
stmt=con.createStatement();
ret = stmt.executeQuery(sql);
}catch(Exception e){
e.printStackTrace();
System.out.println(e.toString());
}
return ret;
}
//执行insert,update,delete,ddl等,返回结果数或0
public int execupdate(String sql){
int recount=0;
try {
stmt=con.createStatement();
recount = stmt.executeUpdate(sql);
}catch(Exception e){
e.printStackTrace();
System.out.println(e.toString());
}
return recount;
}
//关闭打开的内容
public void closecon(){
try{
if (ret != null){
ret.close();
}
if (stmt != null){
stmt.close();
}
if (con != null){
con.close();
}
}catch(Exception ex){
ex.printStackTrace();
}
}

}

3.采用weblogic的连接池jdbc用oracle thin
// 建立数据库的连接
// package com.yourCompany.yourApp;
package db_beans;
import javax.sql.DataSource;
import javax.naming.*;
import java.lang.*;
import java.sql.*;
import java.io.*;
import java.util.*;
public class connect_pool_oracle{
public Connection con = null;
public ResultSet ret=null;
public Statement stmt=null;

//此连接为采用weblogic的jdbc直连接
public connect_pool_oracle(){
try{
Properties props = new Properties();
props.put("connectionPoolID", "WebLogicOraclePool");
try{
Driver myDriver = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
con =myDriver.connect("jdbc:weblogic:pool", props);
}catch(Exception e){
System.out.println(e.getMessage()+e.toString());
}
}catch(Exception ex){
ex.printStackTrace();
System.out.print(ex.toString());
return;
}
}

//执行select语句,并返回结果集
public ResultSet execsql(String sql){
try {
stmt=con.createStatement();
ret = stmt.executeQuery(sql);
}catch(Exception e){
e.printStackTrace();
System.out.println(e.toString());
}
return ret;
}
//执行insert,update,delete,ddl等,返回结果数或0
public int execupdate(String sql){
int recount=0;
try {
stmt=con.createStatement();
recount = stmt.executeUpdate(sql);
}catch(Exception e){
e.printStackTrace();
System.out.println(e.toString());
}
return recount;
}
//关闭打开的内容
public void closecon(){
try{
if (ret != null){
ret.close();
}
if (stmt != null){
stmt.close();
}
if (con != null){
con.close();
}
}catch(Exception ex){
ex.printStackTrace();
}
}

}

4.采用weblogic的连接池用weblogic的jdbc
// 建立数据库的连接
// package com.yourCompany.yourApp;
package db_beans;
import javax.sql.DataSource;

public class connect_db_pool{
public Connection con = null;

public Statement stmt=null;

//此连接为采用weblogic的jdbc直连接

con =myDriver.connect("jdbc:weblogic:pool", props);
}catch(Exception e){
System.out.println(e.getMessage()+e.toString());

}catch(Exception ex){
ex.printStackTrace();
System.out.print(ex.toString());
return;

//执行select语句,并返回结果集
