Tomahawk1.1.3 ugrade exception...ExtensionsFilter not correctly configured. JSF mappi

[ved gunjan]

Hi Experts,

I new to the world of JSF and im presently playing around with MyFaces Tomhawk implementation.
I tried the tree example using tomahawk.jar ,myfaces-api and myfaces-impl.

I was able to get the tree working with these version of jars.



But now when i upgraded to the latest jars i.e
myfaces-api 1.1.3
myfaces-imple1.1.3 and
tomahawk-1.1.3



I'm getting the following error...see the stack trace below:



java.lang.IllegalStateException: ExtensionsFilter not correctly configured. JSF mapping missing. JSF pages not covered. Please see: http://myfaces.apache.org/tomahawk/extensionsFilter.html
org.apache.myfaces.renderkit.html.util.AddResourceFactory.throwExtensionsFilterMissing(AddResourceFactory.java:371)

javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:512)

Dear Ved,

I saw duplicated filter mapping in your web.xml file. See here:

 
 <!-- extension mapping for adding <script/>, <link/>, and other resource
tags to JSF-pages -->
<filter-mapping>
    <filter-name>MyFacesExtensionsFilter</filter-name>
    <!-- servlet-name must match the name of your javax.faces.webapp.FacesServlet entry -->
    <url-pattern>*.jsp</url-pattern>
</filter-mapping>
 
<!-- extension mapping for serving page-independent resources (javascript,
stylesheets, images, etc.) -->
<filter-mapping>
    <filter-name>MyFacesExtensionsFilter</filter-name>
    <url-pattern>/faces/myFacesExtensionResource/*</url-pattern>
</filter-mapping>
<!-- Extensions Filter -->

Maybe you could try to delete the first mapping and keep the second one. In my app I configured the mapping like the second mapping, it works flawlessly.


HTH,
