In a JSF backing bean (Managed Bean, Weld Bean, doesn't matter), I can get the context path the client is on by calling
FacesContext ctx = FacesContext.getCurrentInstance();
String path = ctx.getExternalContext().getRequestContextPath();
This gives me the path the client currently accesses, like /myapplication
.
Is it also possible to get the current page, like /home.faces
, and how?
You normally want to use UIViewRoot#getViewId()
for this.
String viewId = facesContext.getViewRoot().getViewId();
This is in EL also available as follows:
#{view.viewId}
Exactly this value is reuseable in navigation case outcomes such as <h:link outcome>
and <h:button outcome>
.
Alternatively, you can also use HttpServletRequest#getRequestURI()
to get whatever the enduser is actually seeing in the browser address bar.
String uri = ((HttpServletRequest) externalContext.getRequest()).getRequestURI();
Which is in EL also available as follows:
#{request.requestURI}
Exactly this value is reuseable in <h:outputLink value>
or plain <a href>
. Note that you can't use it as navigation case outcome.
Ok, got it, it's
FacesContext ctx = FacesContext.getCurrentInstance();
HttpServletRequest servletRequest = (HttpServletRequest) ctx.getExternalContext().getRequest();
// returns something like "/myapplication/home.faces"
String fullURI = servletRequest.getRequestURI();
