The web application and SB Admin actually needs a little bit more content in the web.xml than you've posted.
The SB Admin specific part additionally is
Code:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:/org/springframework/batch/admin/web/resources/webapp-config.xml</param-value>
</context-param>
<servlet>
<servlet-name>Resources Servlet</servlet-name>
<servlet-class>org.springframework.js.resource.ResourceServlet</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Resources Servlet</servlet-name>
<url-pattern>/resources/*</url-pattern>
</servlet-mapping>
A detailed example you can find in the "Spring Batch Admin Webapp" Spring Batch template project, which is available through the default Spring Tool Suite distribution.
