See code below. The "action" attribute in <form> should be same as url-pattern in web.xml
// UploadServlet.java in WEB-INF/src/UploadServlet.java
//UploadServlet.class in WEB-INF/classes/UploadServlet.class
// myhtm.html
<form name=uploadServlet
action="/UploadServlet" method=post
enctype=multipart/form-data>
<input id=img0 type=file>
</form>
// in web.xml
<servlet>
<servlet-name>UploadServlet</servlet-name>
<servlet-class>app.servlet.UploadServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/UploadServlet</url-pattern>
</servlet-mapping>
