How to get request object, for example the servletPath

[juan_uy]

Hi All,

This question is pretty trivial from the old model (Servlet or Struts). I'm moving to JSF because of the component model, but I need to retrieve the current path of the page, because of the permission mapped to this page in the database. So, how to get the current path inside seam component (request.getServletParh() in the old model).

I have searched in all Seam forum, but wthout results. :(

Thx a lot,
juan.

Try not to use the Servlet API unless you have. Try something similar to this:

@In
private FacesContext facesContext;
private HttpServletRequest request;

public void initComponent(){
 request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
}

Basel,

Thanks!! You saved me many nightmares!!. I 'll not try to use it for business logic, I will simple use to get a node from the database using the servlet path instead of putting a node's id variable in the url parameter :P.

Actually, you should avoid casting to HttpServletRequest if at all possible because your application will break if/when you run it as a portlet.

ExternalContext has methods available for path information.

ExternalContext extCtx = facesContext.getExternalContext();
extCtx.getRequestContextPath();
extCtx.getRequestServletPath();
extCtx.getRequestPathInfo();

etc.
