Is it possible to use JSF file as as error page.

Question

I am using jsf file as an error page.It is working in fine in websphere. But if i am using that only the exception is raised it is not going to error page.
In Web.XML file,
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<error-page>
<error-code>403</error-code>          <location>/faces/unauthorized.jsp</location>
</error-page>
jsf codings are placed under *.jsp files. In the time submitting form data to server a method throws NumberFormatException. This exception information is displayed in console. but blankpage is coming . It is not redirected to error.jsp fle which is under faces/error.jsp.
If i am directly giving /error.jsp then it is giving Faces context is not created error.
So i tried use simple jsp(pure jsp) file wihtin the folder and i set path like /pages/foo.jsp. It is working.
Tell me is it possible to use jsf as error page.

What would you hope to do with the reference?  The Mathscript node doesn't have a file reading capability.  You need to read the file and pass the data into the Mathscript node.
EDIT: I stand corrected.  You need to use the fopen and fclose functions inside of the MathScript node to be able to read a file inside of it.
