1 Establish the system ODBC data source photo (this time I am using Oracle 9i, please contact me if you don’t understand the detailed configuration)
2 Compile the DataBaseConnection.java file and put the compiled file into the class file directory supported by PHP

package com.inberkong.util;
/***************************************************** ***
* Programe File: Copy buffer pool DataBaseConnection.java
*Creat Date:3/28/2005(MM-DD-YYYY)
*Creat By :InberKong(GongYingBin)
* LastModifyDate :3/28/2005(MM-DD-YYYY)
* ModifyBy :InberKong(GongYingBin)
* Function :Get the Oracle DataBaseConnectionPool
//A tool class for finding data sources.

*************************************************** *****/
import java.sql.*;
//Tool class for connecting to the database.
public class DataBaseConnection
{
/**
*A static method that returns a database connection.
*/
public static Connection getConnection()
{

Connection con=null;

Try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:photo","photo","inberkong");//Data source connection information

}
catch(Exception e)
{
e.printStackTrace();
}
Return con;
}
}

3 Compile the processing class for reading the data table and put the processing class into the Java class directory called by PHP
This is a processing class that reads the user role table and returns a JS array of the relationship between users and roles GetUserRolseArray.java
Note: When reading the program, you do not need to care about the related table structure, you can only care about the entire call processing process.
package com.inberkong.processBean;
import java.lang.*;
import java.sql.*;
import java.util.*;
import java.io.*;
import com.inberkong.util.DataBaseConnection;
public class GetUserRolseArray
{
private Connection conss;
private Statement stmtsss=null;
private Statement stmt2=null,stmt3=null;
private ResultSet rstsss=null;
private ResultSet rst2=null,rst3=null;
Private String sqlss="";
Private String sql2="",sql3="";
Private String rString="";
Private String ID,ID2;
Private String NAME;
private int i=0;
public GetUserRolseArray()
{
try
{

This.conss=DataBaseConnection.getConnection();
}
catch(Exception e)
{

}

//DataBaseConnection.getConnection();
}
protected void finalize() throws Throwable
{

//
//super.finalize();
//System.out.println("inberkong");
closeCON();

}

public String getUserRolseArray() throws Exception
{
//exePtempfunction();

sqlss="SELECT ID,NAME FROM ADMIN WHERE 1=1 AND STATE!=0 AND USERTYPE!=0

ORDER BY ID DESC";
//External users do not participate in post-added role management
        stmtsss=conss.createStatement();
rstsss=stmtsss.executeQuery(sqlss); While (rstsss.next())
         {
ID=rstsss.getString("ID");
        ID2=ID;

NAME=rstsss.getString("NAME");
       rString=rString+" "+"arr["+i+"]=new BDSort

("+ID+",00,"+NAME+",);";
       i++;

       sql3="select ID,NAME from ROLE_MANAGE where ID in( select ROLSEID

from USER_ROLSE_LINK where USERID="+ID2+") order by ID asc ";
       stmt3=conss.createStatement();
       rst3=stmt3.executeQuery(sql3);
       while(rst3.next())
       {

       ID=rst3.getString("ID");

       NAME=rst3.getString("NAME");
       rString=rString+" "+"arr["+i+"]=new BDSort

("+ID+","+ID2+","+NAME+",y);";
        i++;
       }

       sql2="select ID,NAME from ROLE_MANAGE where ID not in(select

ROLSEID from USER_ROLSE_LINK where USERID="+ID2+") order by ID asc ";
       stmt2=conss.createStatement();
       rst2=stmt2.executeQuery(sql2);
       while(rst2.next())
       {

       ID=rst2.getString("ID");

       NAME=rst2.getString("NAME");
       rString=rString+" "+"arr["+i+"]=new BDSort

("+ID+","+ID2+","+NAME+",n);";
i++;
}

      }

     rstsss=null;
     return rString;

     }


     public static void main(String[] args){

    //测试如下
        GetUserRolseArray obj1 = new GetUserRolseArray();
