Adding custom filter in spring framework problem?

Question

hello there iam trying to make a custom AuthenticationProcessingFilter to save some user data in the session after successful login

here's my filter:

Code:

package projects.internal;

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.Authentication;
import org.springframework.security.ui.webapp.AuthenticationProcessingFilter;

public class MyAuthenticationProcessingFilter extends AuthenticationProcessingFilter {


 protected void onSuccessfulAuthentication(HttpServletRequest request,
   HttpServletResponse response, Authentication authResult)
   throws IOException {
  super.onSuccessfulAuthentication(request, response, authResult);
  request.getSession().setAttribute("myValue", "My value is set");
 }
}

and here's my security.xml file

Code:

<beans:beans xmlns="http://www.springframework.org/schema/security"  
 xmlns:beans="http://www.springframework.org/schema/beans" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans 
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                        http://www.springframework.org/schema/security 
                        http://www.springframework.org/schema/security/spring-security-3.0.xsd"&gt;

   login-processing-url="/j_spring_security_check"
   login-page="/p/login.jsp"   
   authentication-failure-url="/p/login_error.jsp" />
  <logout />
 </http>

 <authentication-manager alias="authenticationManager">
 <authentication-provider>
    <jdbc-user-service data-source-ref="dataSource"/>
  </authentication-provider>
 </authentication-manager>

 <beans:bean id="authenticationProcessingFilter" class="projects.internal.MyAuthenticationProcessingFilter">
 <custom-filter position="AUTHENTICATION_PROCESSING_FILTER" />
    </beans:bean>

    <beans:bean id="authenticationProcessingFilterEntryPoint" class="org.springframework.security.ui.webapp.AuthenticationProcessingFilterEntryPoint">
    </beans:bean>


 </beans:beans>

it gives an error here: Code:

<custom-filter position="AUTHENTICATION_PROCESSING_FILTER" />

multiple annotation found at this line:cvc-attribute.3 cvc-complex-type.4 cvc-enumeration-vaild

what is the problem? thanks in advance

I don't believe that's a valid filter position in Spring Security 3.0 schema. Check out Security Namespace Configuration. I don't see it listed anymore. Perhaps try BASIC_AUTH_FILTER
