Question

I’m having a little bit of a problem here, whenever I use an action attribute (i.e. <h:commandButton action="/test/test2.whatever" value="Test"/>) jsf changes the extension to .jsf and then redirects me there. So if I press the aforementioned button it would redirect me to /test/test2.jsf. Is this the default behavour and can I change it so only for example files with .xhtml would be changed to .jsf (to be honest this is my first JSF project and the configuration was done by my teammate who’s on vacation).

Answer 1

action should return a string that will be used by the NavigationHandler to decide the next page to render. These navigation rules are defined in the faces-config.xml file, located normally under /WEB-INF.

Besides, there is a context-param in the file web.xml defining what is the default extension of JSF files. I.e.

 <context-param>
  <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
  <param-value>.xhtml</param-value>
 </context-param>

So probably yours is defined to be .jsf and that’s why JSF is changing your .whatever to .jsf

My recomendation is that you shouldn’t decide navigation rules inside the action parameter. Instead you should define them through the faces-config.xml file. I.e:

 <navigation-rule>
  <display-name>login</display-name>
  <from-view-id>/pages/login.xhtml</from-view-id>
  <navigation-case>
   <from-outcome>userLoaded</from-outcome>
   <to-view-id>/pages/user.xhtml</to-view-id>
   <redirect/>
  </navigation-case>
  <navigation-case>
   <from-outcome>userLoadedFail</from-outcome>
   <to-view-id>/pages/login.xhtml</to-view-id>
   <redirect/>
  </navigation-case>
 </navigation-rule>
