写了一个Servlet demo，无法正常访问，求助大神们
<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

<servlet-mapping>
<servlet-name>BaseServlet</servlet-name>
<!--<url-pattern>/servlet/BaseServlet</url-pattern>-->
<url-pattern>ServletTest/BaseServlet</url-pattern>
</servlet-mapping>
现在web.xml配置文件的标签是红色，也是红色。这里到底有啥问题呢？
ServletTest是工程名称 BaseServlet 是一个类。
里面get方法中很简单的代码
public class BaseServlet extends HttpServlet{
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException,IOException{
System.out.print("客户端访问我了2");
doGet(request,response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException,IOException{
System.out.print("客户端访问我了1");
//this.doPost(request,response);
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String title = "HTTP Header 请求实例 - 菜鸟教程实例";
String docType =
"<!DOCTYPE html> \n";
out.println(docType +
"<html>\n" +
"<head><meta charset=\"utf-8\"><title>" + title + "</title></head>\n"+
"<body bgcolor=\"#f0f0f0\">\n" +
"<h1 align=\"center\">" + title + "</h1>\n" +
"<table width=\"100%\" border=\"1\" align=\"center\">\n" +
"<tr bgcolor=\"#949494\">\n" +
"<th>Header 名称</th><th>Header 值</th>\n"+
"</tr>\n");
Enumeration headerNames = request.getHeaderNames();
while(headerNames.hasMoreElements()) {
String paramName = (String)headerNames.nextElement();
out.print("<tr><td>" + paramName + "</td>\n");
String paramValue = request.getHeader(paramName);
out.println("<td> " + paramValue + "</td></tr>\n");
}
out.println("</table>\n</body></html>");
}
这么点代码咋都不能运行呢
截图看看吧，这样看不如直接看项目报错点来的快。将鼠标右键放到报错点上显示报错信息，截图来看看
什么错误啊，和不要一样啊路径要写完整。
BaseServlet 怎么不是包名.类名的形式？
<url-pattern>ServletTest/BaseServlet</url-pattern> 这里的路径不包括项目名的吧？？
还有是不是报404的错误？ 即使报404 页 也可能是页面找不到而不是请求找不到！！！ 如果我说的问题存在，建议先解决！！！

我把前面的项目名称去掉了
变成 /BaseServlet
运行后 log贴出来了 这样的log是不是失败？
很感谢上面回答问题的朋友，问题已经找出！
原因是 ServletTest/BaseServlet 要去掉工程名称：ServletTest
写成这样ok /BaseServlet
