Form表单提交的String ，需要Int， 产生异常

今天接这做我的博客，在博客分类提交时，String与Int之间的类型转换出现异常，暂且记下解决方法：

<s:form action="addSort" method="post">
								<p>
									<label for="sort.pid">类别级别：</label>
									<select name="sort.pid" id="sort.pid">
										<option value="0">-----------</option>
									</select>
								</p>
								<p>
									<label for="sort.name">类别名称：</label>
									<input class="txt" size="20" title="" id="sort.name" name="sort.name" type="text" />
									<span id="namemsg" style="color:#ff0000"></span>
								</p>
								<p>
									<label for="sort.title">类别描述：</label>
									<input class="txt" size="20" title="" id="sort.title" name="sort.title" type="text" />
									<span id="namemsg" style="color:#ff0000"></span>
								</p>
								<p>
									<label for="sort.orderNo">类别排序：</label>
									<input class="txt" size="20" title="" id="sort.orderNo" name="sort.orderNo" type="text" />
									<span id="ordermsg" style="color:#ff0000"></span>
								</p>
								<p>
									<input type="hidden" name="id" id="id" value="" />
									<input class="btn"  id="add" name="add" type="submit" value="确定" />
								</p>
							</s:form>

提交后产生的异常：

解决方法，在实体类里，将Int 改成Integer

public void setOrderNo(int orderNo) {
		this.orderNo = orderNo;
	}

改成：
public void setOrderNo(Integer orderNo) {
		this.orderNo = orderNo;
	}

这样又出新问题Class ognl.OgnlRuntime can not access a member of class modifiers ”private“，但所有setget都是public，不是private。
