No WebContext for Security filter

**Aahzmandius** · Jan 2nd, 2011, 05:43 AM

Hi, I am stucked with implementing spring security to my webproject.
I created project using spring 3.0.5 without ContextLoaderListener.
Everything was working fine, but then i add Spring security filter and i get error

Code:

java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?

web.xml looks like this:

Code:

<!-- Handles all requests into the application -->
	<servlet>
		<servlet-name>EliteCafeServer</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>

				/WEB-INF/spring/security-context.xml
			</param-value>
		</init-param>
		<!-- Creates the Spring Container -->   
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>EliteCafeServer</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>
            org.springframework.web.filter.DelegatingFilterProxy
        </filter-class>
    </filter>

    <filter>
        <filter-name>encoding-filter</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>encoding-filter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

Any suggestions? I already tried to add Listener, but then I get error of multiple Contexts

Spring security needs to be loaded in the root context (at least for the filtering etc). So you really need to ContextLoaderListener.

Also make sure that you load the security config only once (not both the servlet and contextloaderlistener must load this configuration). In general the ContextLoaderListener should load the general components (infrastructure, services, daos'etc.) and the servlet only the specifics (views, viewresolvers, handlers etc.).

So for me it means that I have to:
1) Add ContextLoaderListener into web.xml
2) Make plain DispatcherServlet entry in web.xml
3) Define Dispatcher-Servlet.xml configuration file with servlet specifics
4) Rest of the configurations leave in applicationContext

right?

Basically that are the steps to be taken.

My web.xml looks like this now

Code:

<web-app version="2.4" 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/javaee http://java.sun.com/xml/ns/javaee/web-app_2_4.xsd">


	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener> 

	<listener>
		<listener-class>org.springframework.security.web.session.HttpSessionEventPublisher
		</listener-class>
	</listener>


	<servlet>
		<servlet-name>server</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet
		</servlet-class>
		<load-on-startup>2</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>server</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
 


</web-app>

but now I am getting this error:

Code:

java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!

I am really lost now.

**Marten Deinum** · Jan 2nd, 2011, 12:46 PM

Then there is something else also registering a root ApplicationContext. Do you have some beans which put the loaded context into the ServletContext? There must be something else loading it...

**Aahzmandius** · Jan 2nd, 2011, 02:16 PM

I tottaly stripped application configuration to the minimal core and error still persists.

Code:

Solved double web.xml declaration in pom.xml

**Rob Winch** · Jan 2nd, 2011, 05:30 PM

Can you post the entire stack trace? Just to make sure...Is that your entire web.xml that you are using? You might try enabling logging so you can see anything else that is loading the ApplicationContext.

**Aahzmandius** · Jan 3rd, 2011, 03:14 AM

I figured it out, it was maven configuration error, not spring.
Thanky you for trying to help
