WARNING: JSF1091: No mime type could be found for file QcFormDean.jsp, but wait its a jsf file

Question

I just added jstl-1.2.jar, JSF api, and impl jars to my library so that this could work on my jsf xhtml file.

<h:selectOneMenu value="#{qcFormBean.dliStickerValue}">
    <f:selectItem itemValue="P" itemLabel="Pass or Not applicable" />
    <f:selectItem itemValue="M" itemLabel="FAIL-Mechanical" />
    <f:selectItem itemValue="E" itemLabel="FAIL-Electrical" />
    <f:selectItem itemValue="C" itemLabel="FAIL-Cosmetic" />
    <f:selectItem itemValue="S" itemLabel="FAIL-Software" />
    <f:ajax event="change" execute="@this" render="perfbyDliSticker" />
</h:selectOneMenu>

<h:panelGroup id="perfbyDliSticker">
    <h:selectOneMenu value="#{qcFormBean.performedByRoleID}"
                     rendered="#{!qcFormBean.dliStickerValue eq  'P'}">
        <f:selectItem itemValue="A" itemLabel="Always" />                
        <f:selectItem itemValue="O" itemLabel="Often" />
        <f:selectItem itemValue="S" itemLabel="Seldom" />                
    </h:selectOneMenu>
</h:panelGroup>

Now when i try to access the page on IE i get a 404 missing error and i get the following error on Tomcat and i am not sure what to do at this point the error mentions it as a jsp file and i know i am making this as a jsf file so i am not sure what to do.

and this is my web.xml file.

        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

</web-app>

and here are the jar files in the lib folder

javax.faces.jar 
jsf-api.jar 
jstl-1.2.jar 
jsf-impl.jar

Answer 1

Get rid of jsf-api.jar and jsf-impl.jar. They are already represented by the single javax.faces.jar. Right now you're effectively having two different JSF APIs and impls in webapp's runtime classpath which would only lead to class conflicts in all colors.

Big chance that those are actually of legacy JSF 1.x version (you'd first extract the JAR file with a zip tool and then read the /META-INF/MANIFEST.MF file for the exact version detail) which used the ancient JSP as default view technology which in turn at least explains why all your views were by default interpreted as JSP.

Answer 2

try to add the following lines in the web.xml

<mime-mapping>
    <extension>xhtml</extension>
    <mime-type>application/xml</mime-type>
</mime-mapping>
