Hi,
I am back with my solution for this issue.
This is what I did to solve problem (I hope this can help someone):
SERVER SIDE:
1) Create Filter:
| public class SeamRemotingSessionValidationFilter implements Filter {
|
| public void init(FilterConfig filterConfig) throws ServletException {}
| public void destroy() {}
|
| public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
| HttpSession session =
((HttpServletRequest)request).getSession();
| String servletPath = ((HttpServletRequest)
request).getServletPath();
|
| if( servletPath.startsWith("/seam/resource") &&
| ( session.getAttribute( "loged" ) == null ||
!((String)session.getAttribute( "loged" )).equals("true") ) )
| {
|
((HttpServletResponse)response).getWriter().append("<redirectPage
to='startpage.jsf'/>");
| return;
| }
|
| chain.doFilter(request, response);
| }
| }
|
Code "session.getAttribute( "loged" )" is my indicator for sassion.
2) Register Filter in web.xml:
| <filter>
| <filter-name>SeamRemotingSessionValidationFilter</filter-name>
| <filter-class>
| com.yc.isystem.presentation.filter.SeamRemotingSessionValidationFilter
| </filter-class>
| </filter>
| <filter-mapping>
| <filter-name>SeamRemotingSessionValidationFilter</filter-name>
| <url-pattern>/seam/resource/remoting/*</url-pattern>
| </filter-mapping>
|
CLIENT SIDE:
I decide not to change seam's js libraries so I used Javascript AOP (Aspect
Oriented Programing). We already use dojotoolkit in our project so I used
dojo's aop functions (there are other libraries which are created just for aop
- search google for "js aop"). Next steps are explanation for dojo's aop
functionalities.
3) Import dojo and set required library:
| <script
src="#{facesContext.externalContext.requestContextPath}/js/dojo/dojo.js"
language="javascript"></script>
| <script>
| dojo.require("dojo.event");
| </script>
|
4) Set around advice:
| dojo.event.connect('around', Seam.Remoting, 'processResponse',
'ajaxResponseInterceptor');
|
I put this in html body (tag) onload='--here--' (attribute) but you can put
where you need it.
5) Create js function for redirection:
| function ajaxResponseInterceptor(invocation){
|
| if(invocation.args[0].firstChild.tagName == 'redirectPage'){
| window.location =
invocation.args[0].firstChild.attributes['to'].nodeValue;
| }
|
| var result = invocation.proceed();
| return result;
| }
|
For some other js aop library steps would be same!
If you have problems adding this to you project feel free to ask for help -
I'll help if I can.
IMPORTANT: This is first version so it's possible that there are some issues.
If you seen some please inform me.
Thanks,
Uros.
