Apache CXF 在 WebLogic 9.2 上的问题定位分析及权宜之计

1：IO读写
      因为J2ME只支持有限的几个IO类，要用这几个类满足自己的需求确实不容易。
      try
     {
            InputStream is = new Object().getClass().getResourceAsStream("/52.txt");
            ByteArrayOutputStream baos = new ByteArrayOutputStream(1024);
            byte[] bytes = new byte[128];
            int size;
            while( (size = is.read(bytes)) != -1 ){
                 baos.write(bytes, 0, size);
            }
           data = baos.toByteArray();
           iSize = data.length;
           contentCan = new contentCanvas(new String(data));
           is.close();
           is = null;
           baos.close();
           baos = null;
     }
     catch (Exception e)
     {
          e.printStackTrace();
     } 
2：字符串转换成整数或其它primitive类型
  image_1_num = Integer.parseInt(str3.substring(0,str3.indexOf("-")));
  image_2_num = Integer.parseInt(str3.substring(str3.indexOf("-")+1));
用了无数次了，但每次还是忘记。
3：ChoiceGroup的一个小问题
看API文档

public ChoiceGroup(String label,                   int choiceType,                   String[] stringElements,                   Image[] imageElements)

Creates a new

ChoiceGroup

, specifying its title, the type of the

ChoiceGroup

, and an array of

Strings

and

Images

to be used as its initial contents.The type must be one of

EXCLUSIVE

,

MULTIPLE

, or

POPUP

. The

IMPLICIT

type is not allowed for

ChoiceGroup

.
The

stringElements

array must be non-null and every array element must also be non-null. The length of the

stringElements

array determines the number of elements in the

ChoiceGroup

. The

imageElements

array may be

null

to indicate that the

ChoiceGroup

elements have no images. If the

imageElements

array is non-null, it must be the same length as the

stringElements

array. Individual elements of the

imageElements

array may be

null

in order to indicate the absence of an image for the corresponding

ChoiceGroup

element. Non-null elements of the

imageElements

array may refer to mutable or immutable images.
有以下问题要澄清：
1：第二个参数类型只能为EXCLUSIVE,

MULTIPLE

, or

POPUP，IMPLICIT 不被支持，这点和List不同。

2：第三个参数不能为null。

3：第四个参数可以为null。

但是不知道为什么，在我的开发中，始终无法用POPUP类型，Eclipse老提示无法解析此类型。
