[jboss-user] [JBoss Seam] - Re: Access Seam Component from Servlet Filter in JSF Request

[wadahiro]

Thank you for your advice.

I made a custom filter that is called inside the Seam context filter.
Although Contexts access that is called before doFilter method of
next filter is successful, the access that is called after doFilter method
cause IllegalStateException because of No active Contexts.

It seems that SeamPhaseListener already destroy Contexts after render response,
so my custom filter can't access the Contexts.

How do I access to Contexts after doFilter method?


My sample code is as follows.

custom filter code is:


  | @Startup
  | @Scope(ScopeType.APPLICATION)
  | @Name("filtertest")
  | @BypassInterceptors
  | @Filter(within = "org.jboss.seam.web.contextFilter")
  | public class FileterTest extends AbstractFilter {
  | 
  | 	public void doFilter(ServletRequest arg0, ServletResponse arg1,
  | 			FilterChain arg2) throws IOException, ServletException {
  | 		String s = Interpolator.instance().interpolate("#{cookie}");
  | 		System.out.println(s);
  | 		arg2.doFilter(arg0, arg1);
  | 	}
  | 
  | }
  | 

and WEB-INF/components.xml is:


  | 	<web:context-filter />
  | 

and console log is:
