My server has been using spring security (current version 3.0.5.RELEASE) successfully on its SOAP interface for a long time.

The server also has a REST interface implemented using jersey. I am now adding spring security based authentication on some of the Jersey resource methods. I want the REST client to be forced to authenticate when accessing the search() method of my jersey resource. So I annotate it with the org.springframework.security.access.prepost.PreAut horize annotation as follows:

Code:
@Path("/")
@Component
@Scope("singleton")
public class MyRestResource {

    @Path("/search")
    @GET
    @PreAuthorize("isAuthenticated()")
    public Response search(...) {
    }
}
Next I edited my web.xml to add the following:

Code:
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" 
  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_2_4.xsd">
    ...
    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>
        org.springframework.web.filter.DelegatingFilterProxy
        </filter-class>
    </filter>

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

    </filter-mapping>
    ...
</web-app>
Finally I edited my servers application context to enable form based authentication on my REST interface with teh following additions:

Code:
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:security="http://www.springframework.org/schema/security"
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:p="http://www.springframework.org/schema/p"
       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
       http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
    ...
    <security:global-method-security pre-post-annotations="enabled" />

    <security:http auto-config='true'>
        <security:intercept-url pattern="/**"  />
        <security:anonymous username="guest" granted-authority="ROLE_Guest"/>
        <security:form-login/>
        <security:logout/>
    </security:http>    
<beans>
When I start my server it works as normal with SOAP requests (good, nothing broke). When I try the REST request it tries to navigate to http://localhost:8080/my-app-context...security_login (good, redirect is being attempted). However, it gets a 404 when accessing that page (bad).

Can any one guide me as to why I am getting a 404 on the spring-security provided web page spring_security_login? Also, where can I find the source to this page so I can customize it.
Thank you for your help.
