关于jsp中form表单提交大数据问题
在一个SSH项目里，一个jsp页面上一段代码如下
<form id="test-form" action="test.do" METHOD="POST">
  <input type="hidden" name="ids" id="ids" value=""/>
  <input type="hidden" name="method" value="doTest"/>
</form>

然后通过jquery提交表单

出现以下错误

经测试，是因为表单数据太大引起，如果只取上面字符串的一半长度，就不会出现错误。
但是在另一SSJ项目中测试，却没有出现错误。

两个项目部署在同一tomcat下，都使用firefox测试。

求高手指教

新手 前来混个脸 没遇到过这样的情况
[解决办法]
java.lang.ArrayIndexOutOfBoundsException 这个异常就是超过了字符串类型长度或者数组下标。
[解决办法]
兄弟，用类似的这种方式做：

$.post(url,$("#test-form']").serialize(), function(data){
var r = eval("("+data+")");
if(r.status){
parent.jsonForumContentList();
parent.jsonForumContentList();
parent.closeDialog(r.message);
}

}, "json");
[解决办法]
ArrayIndexOutOfBoundsException数组越界了。
[解决办法]
get传送的数据量较小，不能大于2KB
好像使这yang?
[解决办法]

HTML code

$.ajax({                type:"POST",                url:"/xxx.do",                dataType:"JSON",                data:$('#addRoleForm').serialize(),                success:function(data){                    alert("SUCCESS")                },                error:function(){                    alert("request error");                }            });
[解决办法]
探讨


很明显是提交方式引起的问题，GET是有大小限制的，一般提交表单都用POST提交，ajax提交请指定type:"POST"
另外.serialize()方法是把form中的字段拼接成xxx=xxx&xxx=xxx.具体看firebug的信息。

[解决办法]
感觉是缓冲区的关系
