This error can occur when loading a JSF/Facelets page :-
org.apache.jasper.JasperException: /home.jspx(16,17)
#{...} is not allowed in template text
One reason for this, described on JavaRanch here, is that the JSF page is not being routed properly via the servlet mapping in web.xml. The following extract from web.xml shows a mapping for .iface, to route urls ending in .iface to the ICEfaces Persistent Faces Servlet:-
<servlet-mapping> <servlet-name>Persistent Faces Servlet</servlet-name> <url-pattern>*.iface</url-pattern> </servlet-mapping>
Even though the page itself may be a .jspx file, using .jspx rather than .iface in the url would not route the page to the above servlet, causing it to be parsed incorrectly. This post describes the cause in more detail – the #{…} syntax is unified EL, which is not allowed in template text in a JSP (hence the error). In the above case the page was being treated as a JSP rather than a Facelet due to the incorrect routing.
