[SOLVED] JSF with ExtensionlessURLs / Omnifaces

JSF with ExtensionlessURLs / Omnifaces

I´m trying to use ExtensionlessURLs in my JSF app...

I´m using already: https://showcase.omnifaces.org/facesviews/ExtensionlessURLs This works fine, but if I have a URL with a parameter it´s still with:

mypage.jsf?myparameter=12345

Is there a possibility to exclude here also .jsf, so the URL will be:

mypage?myparameter=12345

I know also Prettyfaces is available, but here I guess I have to define for each JSF page a mapping? Therefore I was using Omnifaces...

Any idea to help here?

Solution

It appears that you've an existing JSF application whose FacesServlet is mapped to *.jsf instead of *.xhtml and are trying to enable extensionless URLs through OmniFaces FacesViews using its default "minimal" configuration.

This will indeed not work without making other changes to the existing JSF application.

FacesViews expects that you have already mapped the FacesServlet to the URL pattern of *.xhtml which is recommended since JSF 2.0. So you need to make the following adjustments:

Change FacesServlet mapping from *.jsf to *.xhtml in web.xml.
Find & replace all occurrences of .jsf throughout source code with .xhtml. So e.g.
```
ec.redirect(ec.getRequestContextPath() + "/portal/employeeEdit.jsf" + "?id=" + id);
```
must become
```
ec.redirect(ec.getRequestContextPath() + "/portal/employeeEdit.xhtml" + "?id=" + id);
```
A bit decent IDE can do this in a few clicks (e.g. Eclipse Ctrl+H, File Search, find .jsf in Enclosing project and replace by .xhtml).

Alternatively, wait for OmniFaces 2.7.11 or 3.11 or 4.0-M8 to be released. I've today fixed this backwards compatibility issue in these versions as per issue 623. With this fix, the existing *.jsf URLs will properly be automatically 301-redirected to the extensionless ones.

Note that this problem is not specifically related to URLs with parameters. It would also happen to URLs without parameters.
