1. action="testservlet"是相对目录，访问
http://localhost:8080/JspServletapp/testservlet
2. action="/testservlet"是绝对目录, 访问
http://localhost:8080/testservlet
搂住写成了绝对目录所以报错，可以改成相对目录或者
action="/JspServletapp/testservlet"
都可以访问
http://localhost:8080/JspServletapp/testservlet
2. action="/testservlet"是绝对目录, 访问
http://localhost:8080/testservlet

JspServletapp/TestServlet
或者JspServletapp/jspservlet/TestServlet
或者其他的情况，看web.xml怎么写了
不是让你贴web.xml了吗？

我用
http://localhost:8080/JspServletapp/hello.jsp
访问JSP页面
可是一访问servlet页面地址就变成
http://localhost:8080/testservlet
怎么servlet不成servlet上下文中了？

也许你的web.xml的servlet url pattern跟页面的action地址没匹配好

服务器没有配置好，或者地址输错了？
