麻烦大家给我看看那里有错？！实在不知道了。急
JSP页面跳到servlet进行处理，后在跳回原JSP页面。可提示在 int count=Integer.valueOf(strCount);提示错了----- java.lang.NumberFormatException: For input string: "null>"
JSP：<form action="sGame" method="post" >
<nobr>请输入小于10的自然数：<input type="text" name="number"/><input type="submit" value="确 定"/></nobr>
<input type="hidden" name="random" value="<%=request.getParameter("random") %>>"/>
<input type="hidden" name="count" value="<%=request.getParameter("count") %>>"/>
<%
String info=request.getParameter("info");
if(info!=null)
{
%>
<font color="red"><%=info%></font>
<% }%>
servlet：
System.out.println("Hello World!");
String number=request.getParameter("number");
String random=request.getParameter("random");
String strCount=request.getParameter("count");
String info=null;
if(random==null)
{
random=""+Math.round(Math.random()*10);
}
try{
if(number!=null)
{
if(strCount.equals("null"))
{
strCount=""+1;
}
int count=Integer.valueOf(strCount);
if(number.trim().equals(random))
{
info=getInfo(count);
}
else{
if(Integer.parseInt(number)>Integer.parseInt(random)){
info="偏大,";
}
if(Integer.parseInt(number)<Integer.parseInt(random)){
info="偏小,";
}
info+="还有"+(3-count)+"次机会.";
}
info="上次猜测的数字是"+number+","+info;
response.sendRedirect("cGame.jsp?random="+random+"&count="+(++count)+"&info="+info);
}else{
response.sendRedirect("cGame.jsp");
}
}catch(NumberFormatException e) {
e.printStackTrace();
}
