StackOverFlowError при создании объекта Mac на AS400 / Java

/ 17 июня 2010

Я новичок в программировании на AS400-Java. Я пытаюсь создать свою первую программу для проверки реализации кода аутентификации сообщений (MAC). Я пытаюсь использовать хэш-функцию HMACSHA1. Моя (Java 1.4) программа отлично работает на устройстве dev (V5R4). Но на сервере QA (V5R3) происходит ужасный сбой Моя программа, как показано ниже:

=============================================== ====== 


import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.security.Security;
import java.security.Provider;

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import javax.crypto.SecretKey;

public class Test01
{
 private static final String HMAC_SHA1_ALGORITHM = "HmacSHA1";

 public static void main (String [] arguments)
 {
  byte[] key = { 1,2,3,4,5,6,7,8};
  SecretKeySpec SHA1key = new SecretKeySpec(key, "HmacSHA1");
  Mac hmac;
  String strFinalRslt = "";

  try {
 hmac = Mac.getInstance("HmacSHA1");
 hmac.init(SHA1key);
 byte[] result = hmac.doFinal();
    strFinalRslt = toHexString(result);

  }catch (NoSuchAlgorithmException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
  }catch (InvalidKeyException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
  }catch(StackOverflowError e){
 e.printStackTrace();
  }
  System.out.println(strFinalRslt);
  System.out.println("All done!!!");
 }

 public static byte[] fromHexString ( String s )
 {
  int stringLength = s.length();
  if ( (stringLength & 0x1) != 0 )
  {
   throw new IllegalArgumentException ( "fromHexString requires an even number of hex characters" );
  }
  byte[] b = new byte[stringLength / 2];

  for ( int i=0,j=0; i>> 4] );

  //look up low nibble char
  sb.append( hexChar [b[i] & 0x0f] );
 }
 return sb.toString();
}

static char[] hexChar = {
'0' , '1' , '2' , '3' ,
'4' , '5' , '6' , '7' ,
'8' , '9' , 'a' , 'b' ,
'c' , 'd' , 'e' , 'f'};


}

Эта программа прекрасно компилируется и получает правильный ответ на моем клиенте win-xp, а также на моем компьютере разработчика. Но происходит сбой со следующей ошибкой в ​​окне QA:

Я проверил файл java.security и запись, соответствующую файлам jce, все в порядке. Команда DMPJVM дает мне следующий ответ:

Похоже, проблема 

at java.io.Os400FileSystem.list(Native method)
at java.io.File.list(File.java:922)

Код Mac.getInstance () должен прочитать папку (File.list), что выполняется методом Os400FileSystem.list (). Очевидно, эта папка слишком велика.

Первое, что вам нужно проверить, это то, что машина работает на PTF. Если проблема остается, попробуйте дать вашему процессу больше памяти (аргумент команды JAVA / RUNJVA), чтобы проверить, не слишком ли мало памяти. Значения по умолчанию были увеличены с V5R3 до V5R4.
