jsf - How do I exclude servlet-filters from having to be serialized? -

-

i converted beans viewscoped instead of requestscoped. however, since had add serialized beans, getting 2 java.io.notserializableexception exceptions.

this web.xml:

<filter>   <filter-name>primefaces fileupload filter</filter-name>   <filter-class>org.primefaces.webapp.filter.fileuploadfilter</filter-class> </filter> <filter>    <filter-name>loginfilter</filter-name>    <filter-class>com.company.rews.webclient.controller.loginfilter</filter-class> </filter>  <servlet>   <servlet-name>faces servlet</servlet-name>   <servlet-class>com.company.rews.webclient.controller.myfacesservletwrapper</servlet-class>   <load-on-startup>1</load-on-startup> </servlet>

the first place reports exception somewhere inside super.service(req, res):

public class myfacesservletwrapper extends myfacesservlet  {  @override public void service(servletrequest request, servletresponse response)         throws ioexception, servletexception {     httpservletrequest req = (httpservletrequest) request;     httpservletresponse res = (httpservletresponse) response;              req.setcharacterencoding("utf-8");     res.setcharacterencoding("utf-8");              try     {            super.service(req, res);             }     catch (servletexception e)     {                    e.printstacktrace();         loginfilter.gotologin(e, req, res);     }         }

}

and here @ chain.dofilter(request, response): 

public class loginfilter implements filter {  private static final string system_error_uri = "/login.faces";  private static final string viewex_error_uri = "/login.faces";  @override public void dofilter( servletrequest req, servletresponse res, filterchain chain ) throws ioexception, servletexception {      httpservletrequest  request  = (httpservletrequest) req;     httpservletresponse response = (httpservletresponse) res;      if ( isresourcerequest(request, response) )     {         chain.dofilter(request, response);     }     else if ( !isloggedin(request, response) && isloginarea(request, response) )     {         gotologin(null, request, response);     }     else if( !isuserconnectedtorews( request ) && isloginarea(request, response) )     {         gotologin(null, request, response);     }     else     {         chain.dofilter(request, response);     }  }

here complete error report:

how exclude servlet-filters having serialized if that's problem here @ all?

just stop assigning facescontext, externalcontext , of artifacts instance variable. should always, obtain , assign them in thread local scope (i.e. inside method block).

please note has nothing servlet filters.
