For php calls java, here presents a new method, which ues cle developed by srplab.A function “Add” is defined in lua which returns the sum of two input integers. The function also calls php method “Show” to print the result.

There are three steps:

1.       Init cle, create service group, and create service.

2.       Define extends class of StarObjectClass, and defines a new function “Add” of it.

3.       Create interface object, named “TestClass”.

import com.srplab.www.starcore.*;

//--Step2 : Define extends class of StarObjectClass, and defines a new function “Add” of it.

class MyObjectClass extends StarObjectClass

{

    public int Add(StarObjectClass self, int x, int y)

{

//--Callback to script function

        self._Call("Show", x + y);

        return x + y;

    }

    public MyObjectClass(StarObjectClass srcobj)

    {

              super(srcobj);

    }

}

public class AddFunctionService{

         public static void main(String[] args){

         //--Step1 : Init cle, create service group,import sharelibrary,  and create service

                   StarCoreFactory starcore= StarCoreFactory.GetFactory();

                   StarServiceClass Service=starcore._InitSimple("AddFunctionService","123",0,0);

         //--Step3 : Create interface object, named “TestClass”.

                   MyObjectClass Obj = new MyObjectClass(Service._New("TestClass"));

    }

} 

For php code calls the above java file, there are three steps;

1.       Init cle, create service group,import java file,  and create service.

2.       Create Instance of object “TestClass” defined in java.

3.       Call function “Add”.

<?php

   Step 1 : Init cle, create service group,import java file,  and create service.

   $starcore = new StarCoreFactory();

   $Service=$starcore->_InitSimple("test","123",0,0," AddFunctionService.class?script=java");

   Step 2: Create Instance of object “TestClass” defined in java.

   $a = $Service->TestClass->_New();

   function a_Show($self,$Para)

   {

       echo "from php call back"  ,$Para,"\n";

   }

   $a -> Show = "a_Show";

   Step 3: call function “Add”

   $Result = $a->Add(12,34);

   echo "Add returns : ",$Result,"\n";

   $Service->_ServiceGroup->_ClearService();

   $starcore->_ModuleExit();

?>
