servlet找不到的问题

Question

webroot下的jsp中img src="/servlet/TopologyServlet
web.xml中也改了配置：
<servlet>
  <servlet-name>TopologyServlet</servlet-name>
  <servlet-class>com.Bmavweb.servlet.TopologyServlet</servlet-class>
 </servlet>
 <servlet-mapping>
  <servlet-name>TopologyServlet</servlet-name>
  <url-pattern>/servlet/TopologyServlet</url-pattern>
 </servlet-mapping>
还是不能显示
/Bmavweb/src/com/Bmavweb/servlet/TopologyServlet.java这是文件的路径

Answer 1

img src="servlet/TopologyServlet
这样试试

Answer 2

/servlet/TopologyServlet  还这个里面的servlet去掉

Answer 3

加上全路径试一下。request.getContextPath()

Answer 4

img src="servlet/TopologyServlet
不能有“/”去掉就可以了。

Answer 5

关键是我直接localhost：8080/项目名/servlet/文件名 都提示is not available

Answer 6

 <servlet>
    <servlet-name>ImgServlet</servlet-name>
    <servlet-class>base.servlet.ImgServlet</servlet-class>
  </servlet>
<servlet-mapping>
    <servlet-name>ImgServlet</servlet-name>
    <url-pattern>/servlet/ImgServlet</url-pattern>
  </servlet-mapping>访问路径<img src="${basePath }/servlet/ImgServlet" onclick="return changeImg();" name="imgvalicode" id="imgvalicode">

Answer 7

basePath<c:set var="base" scope="page" value="${request.scheme}://${request.serverName}:${request.serverPort}" />
<c:set var="contextPath" scope="page" value="${request.contextPath}" />
<c:set var="basePath" scope="page" value="${base}${contextPath}" />
