Hi All,

This is my first servlet program. I wanted to try a web application where "register" user module will be in servlet program.

I can access my index.jsp but when I enter values and click submit, I get "There is no Action mapped for namespace [/] and action name [RegisterUserServlet] associated with context path [/TrainingApplication]. - [unknown location]".

Here's my index.jsp file:

Here's my web.xml:

<web-app id="WebApp_9" version="3.0"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_3_0.xsd">

<filter>
		<filter-name>MutedFilter</filter-name>

		<url-pattern>/register</url-pattern>
	</servlet-mapping>

<welcome-file-list>

	</welcome-file-list>

</web-app>

My register servlet:

I am using apache-tomcat-8.0.14 server. Can somebody help me spotting the issue?

Thanks,

The form action should be server-relative starting with the context path. See the JspFaq for more info.
