Tomcat遇到500 The server encountered an internal error that prevented it from fulfilling this request

故事背景:
我使用jdk1.8和tomcat8.0但是遇到了下边两个问题

![在这里插入图片描述](https://img-blog.csdnimg.cn/20210603211006342.jpg?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2FiY2RkZGRkeg==,size_16,color_FFFFFF,t_70#pic_cente
然后我重新下了个tomcat好了，他的版本如下：

然后成功了。。。。。

原因百度了一下：tomcat的版本要比jdk的版本高

除此之外，我的代码也有问题。
下边这个是错误的代码：

<%@ page contentType="text/html;charset=UTF-8" %>
<%@ taglib tagdir="/WEB-INF/tags" prefix="computer"%>
<html>
输入的三个数值a,b,c（代表三角形的三边或梯形的上底、下底和高）;
<body color=cyan><form action="" method=get name=form> <%-- 获取参数提交给自己--%><table><tr><td>输入数值a：</td><td><input type="text" name="a"></td></tr><tr><td>输入数值b：</td><td><input type="text" name="b"></td></tr><tr><td>输入数值c：</td><td><input type="text" name="c"></td></tr></table><input type="radio" name="r" value="triangle">代表三角形<input type="radio" name="r" value="lader">代表梯形<br><input type="submit" name="submit" value="提交" name=submit>代表提交按钮</form><% String a=request.getParameter("a");String b=request.getParameter("b");String c=request.getParameter("c");String cd=request.getParameter("r");if(a==null||b==null||c==null){a="0";b="0";c="0";cd="0";}if(a.length()>0&&b.length()>0&&c.length()>0){%><computer:Getarea numberA="<%=a%>" numberB="<%=b%>"numberC="<%=c%>" condition="<%=cd%>"/><br><%= message%><br><%= area %><% }%></body></html>

错的原因竟然是多了两个空格，报错是一样的。
下面是正确的代码：

<%@ page contentType="text/html;charset=UTF-8" %>
<%@ taglib tagdir="/WEB-INF/tags" prefix="computer"%>
<html>
输入的三个数值a,b,c（代表三角形的三边或梯形的上底、下底和高）;
<body color=cyan><form action="" method=get name=form> <%-- 获取参数提交给自己--%><table><tr><td>输入数值a：</td><td><input type="text" name="a"></td></tr><tr><td>输入数值b：</td><td><input type="text" name="b"></td></tr><tr><td>输入数值c：</td><td><input type="text" name="c"></td></tr></table><input type="radio" name="r" value="triangle">代表三角形<input type="radio" name="r" value="lader">代表梯形<br><input type="submit" name="submit" value="提交" name=submit>代表提交按钮</form><% String a=request.getParameter("a");String b=request.getParameter("b");String c=request.getParameter("c");String cd=request.getParameter("r");if(a==null||b==null||c==null){a="0";b="0";c="0";cd="0";}if(a.length()>0&&b.length()>0&&c.length()>0){%><computer:Getarea numberA="<%=a%>" numberB="<%=b%>"numberC="<%=c%>" condition="<%=cd%>"/><br><%=message%><br><%=area %><% }%></body></html>做人要细心啊啊啊啊！
