I am trying to set a property to a bean ModelBean in a Filter and access this property in a JSF controller IndexController.
The ModelBean is annotated @SessionScoped and it is used in the filter and controller with @Inject. The problem is that two separate instances are created and I cannot access the property that I set in filter.
What would be the best way to keep the bean alive throughout the session? Or maybe there is a better method to pass data from the filter?
@SessionScoped
public class ModelBean{
private String deviceId;
public ModelBean() {
super();
}
public String getDeviceId() {
return deviceId;
}
public void setDeviceId(String deviceId) {
this.deviceId = deviceId;
}
}
@Provider
public class AuthRequestFilter implements Filter {
@Inject
ModelBean model;
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws
IOException, ServletException {
// the device id is set just fine
model.setDeviceId(deviceId);
filterChain.doFilter(servletRequest, servletResponse);
return;
}
}
@Named(value = "indexController")
public class IndexController {
@Inject
ModelBean model;
// the method **is* called from the xhtml
public String justAnExample() {
// this is the problem, the deviceId is null=>
return model.getDeviceId();
}
}
