页面检查报错和eclipse报错：jsp页面没有传值到控制器。

严重: Servlet.service() for servlet [dispatcherServlet] in context with path [/Mold] threw exception [Request processing failed; nested exception is java.lang.NumberFormatException: null] with root cause

$.ajax({
		"url":"${pageContext.request.contextPath}/xx/get.do",
		"data":"companyid="+$("#companyid").val()
				+"&pageNow="+pageNow
				+"&pageSize=" + pageSize,     
		"type":"POST",
		"dataType":"json",
		"success":function(obj){

"&pageNow="+pageNow
"&pageSize=" + pageSize,    

报错的原因是以上两个值忘记写了，就报错，说是null。
