json-lib.jar开发包使用:

依赖包:
commons-beanutils.jar;
commons-httpclient.jar;
commons-lang.jar;
ezmorph.jar;不少人使用时会提示net.sf.ezmorph.xxx找不到,就是缺这个:
morph-1.0.1.jar

使用过程中问题:
1,把bean转化为json格式时老提示如下错误:
Exception in thread "main" net.sf.json.JSONException: java.lang.NoSuchMethodException: Property 'name' has no getter method
解决:声明bean为public class xxx,必须是public,我用默认类型(class xxx)都不行

2,Exception in thread "main" java.lang.NoSuchMethodError: org.apache.commons.lang.ArrayUtils.toObject([C)[Ljava/lang/Character;
原因:定义属性如下:private char[] options = new char[] { 'a', 'f' };好像不能处理这种类型的

3, private String func1 = "function(i){ return this.options[i]; }";
?? 和
?? private JSONFunction func2 = new JSONFunction(new String[] { "i" },
???? "return this.options[i];");
?? 转换后显示结果差不多:
?? {"func1":function(i){ return this.options[i];,"func2":function(i){ return this.options[i]; }}
