server tomcat v8.0 server at localhost failed to start
<p>I seem to have a problem with my web.xml file.
every time I run the Apache tomcat 8 server, it gives this error:
server tomcat v8.0 server at localhost failed to start.</p>

<p>when I removed the servlets of the xml file, the server worked!!
my web.xml is as follow:</p>

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"&gt;
