try this
试试这个
int rowcount = (int) request.getAttribute("inCount");
**OR**
int rowcount = Integer.parseInt(request.getAttribute("inCount"));

If you want to show the value of the variable 'inCount' you can use c:out
如果要显示变量“inCount”的值，可以使用 c:out
So if you write :
所以如果你写：
<c:out value="${inCount}"/>
it will show the value of 'inCount'.
它将显示“inCount”的值。
Otherwise, if what you want is to reassign the variable inCount of your scope to a new variable you should use c:set
否则，如果您想要将作用域的变量 inCount 重新分配给新变量，则应使用 c:set
<c:set var="rowCount" scope="session" value="${inCount}"/>
