[Php-java-bridge-users] how to debug the php script which calls the java function

[<php...@li...>]

hello,erverybody
      I am sorry, in my former letter, I did not describe my problem clearly! I will give more information.
      My website is written in php script and I have to call some java fuctions(these functions is used to implement a complicated algorithms), so i have to user the php-java-bridge to connect php and java,but I find it is very difficult to debug my programme. When I forget to include some libs, the php page just display
nothing, this situation slow my speed of developing very much. I hope someone is so kindly to tell me some way to debug my programme.
      I am a newer to begin programming with php_java_bridge(begin from last Monday). In the coding process, I encountered two problems:
      1. I can't use new a object with the parameter .
         for example: 
it is ok:    $obj = new Java("parser.ParseNode);
it is not ok    $pobj = new Java("parser.ParseNode","/home/lvhl/apache/test/parseweb/bin/elong.htm","gb2312"); 
                  //class parser.ParseNode has a construct function : ParseNode(String str ,String encoding)
       2. I can't call a non-static function fo parser.ParseNode
           also use the same example:
                                 it is ok :
                                               $obj = new Java("parser.ParseNode);
                                               echo $pobj->printHello();  //printHello is a static function of parser.ParseNode
                                 it is not ok and output is nothing:  echo $pobj->printTest();  //printTest is not a static function 
                                                                                                                   of parser.ParseNode
        define of the functions:
                             
                                   public static String printHello()
        {
return "Hello World,dajiahao!";
   }

   public String printTest()
  {
return "Hello,test!";
  }

      Is there anybody who is so kind to tell me why ? Thank you very much!
