的Websphere 7：JAX-WS消息編碼錯誤

Question

當調用是應該以特殊字符（一種交叉），我有以下錯誤返回一個字符串web服務：

顯然即使編碼是有效的，XML文檔也不是。

我發現的唯一方法在這篇文章中被描述：

http://blog.mark-mclaren.info/2007/02/invalid-xml-characters-when-valid-utf8_5873.html

public String stripNonValidXMLCharacters(String in) { 
    StringBuffer out = new StringBuffer(); // Used to hold the output. 
    char current; // Used to reference the current character. 

    if (in == null || ("".equals(in))) return ""; // vacancy test. 
    for (int i = 0; i < in.length(); i++) { 
     current = in.charAt(i); // NOTE: No IndexOutOfBoundsException caught here; it should not happen. 
     if ((current == 0x9) || 
      (current == 0xA) || 
      (current == 0xD) || 
      ((current >= 0x20) && (current <= 0xD7FF)) || 
      ((current >= 0xE000) && (current <= 0xFFFD)) || 
      ((current >= 0x10000) && (current <= 0x10FFFF))) 
      out.append(current); 
    } 
    return out.toString(); 
}
