    get a session seam variable from servlet filter

    Federico Rodriguez Newbie
      Hi, I am trying to get a session seam variable from servlet filter

         @Name("mybean")
         @Scope(ScopeType.SESSION)

         public class Mybean{
           private String var; 
         }

      and the servlet Filter :

         public class MyFilter implements Filter {
        
           MyBean bean;

             @Override
             public void destroy() {
              // TODO Auto-generated method stub
             }

             @Override
             public void doFilter(ServletRequest request, ServletResponse response,   
             FilterChain    chain) throws IOException,
                  ServletException {
          
           this.bean = org.jboss.seam.Component.getInstance("mybean");

              chain.doFilter(request, response);
          }

          @Override
          public void init(FilterConfig filterConfig) throws ServletException {      
          }
         }


      But i got an exception no active context.

      Anyone can help me?

      Thanks.

          I get the same thing. Generally in a seam application it is recommended that you use the filter annotations, in my primary seam application this works perfectly... I have another war file with an old spring project that I am integrating with seam. It uses acegi for security and although I have gotten it to bootstrap, I get the same error as you when logging in.


          I am trying to expose a few of the classes it uses as seam components to see if that makes a difference, otherwise I think another way around it is to extends the old filter and use the annotations seam provides.

            What are the annotations on your filter?


            The Seam example in the doco is like this:


            @Startup
            @Scope(APPLICATION)
            @Name("org.jboss.seam.web.multipartFilter")
            @BypassInterceptors
            @Filter(within="org.jboss.seam.web.ajax4jsfFilter")
            public class MultipartFilter extends AbstractFilter {
            



            What have you got?
