RE: How do I properly use jsp:forward in MyFaces?

Todd,
 
You need to get rid of the Tomahawk references, which is the only reason you would have the extensions filter. This note was on the front page of the myfaces.apache.org site:
 
Please pay attention to the fact that you cannot use this release of MyFaces Core with the MyFaces Tomahawk library in version 1.1.1 - it will only work with the Tomahawk library in version 1.1.2 and onward. (The 1.1.2 release is currently only available as a nightly. The official release is expected in a few days.)
 
Where "This release" is myfaces v 1.1.2 as you mentioned below. Getting rid of the extensions filter should clear some things up as long as you do not, for right now, plan on using the Tomahawk "t" taglib.  For learning purposes, I recommend staying away from that taglib.
 
Regards,
David

No errors in the log file.

Plus, I changed the jsp-forward tag to:
 
<jsp:forward page="tbrowser.jsf"/>
 
Now I get the same ole' error:
javax.servlet.ServletException: ExtensionsFilter not correctly configured. JSF mapping missing. JSF pages not covered.
 
What's interesting is when I look in the myfaces-impl-1.1.2.jar, the following package isn't there:
 
org.apache.myfaces.webapp.filter
 
Only:
 
org.apache.myfaces.webapp
 
 
What is going on? Geez... I did get the simple.war to work, blank.war had a _javascript_ error.
 
Thanks,

Todd,
 
Does your web server have any startup errors in the log files for the /transactionbrowser web application?  Also, have you put a simple/basic JSF page in /tbrowser.jsp and can you post it so we can check the syntax?

David

Hi,

Removing the "/" at the beginning may work,

<jsp:forward page="faces/tbrowser"/>

Todd,
 
From your various posts tonight, you seem to have a number of JSF concepts mixed.  Is this your first Faces Webapp? (That is not meant to be an insult but a simple question)
 
If your project folder looks like this as you indicated:
 
/transactionbrowser/
- WEB-INF
- resources
-index.jsp
-tbrowser.jsp
 
Then the various mappings you have posted over the past 24 hours have often been incorrect.  With this webapp, your main url would likely be:
http://127.0.0.1/transactionbrowser and you would expect it to invoke the welcome page /index.jsp.  Your example index.jsp was listed as:
 
<jsp:forward page="/faces/tbrowser.jsp"/>
 
THAT is where your first make came from: your mappings.  JSF is often taught using SUFFIX mapping so the urls such as /index.jsf are understood to be imaginary (no such file exists) allowing the servlet to map /index.jsf to compile the view from the jsp file /index.jsp.  With prefix mapping the url "/index.jsf" would be equivalent to "/faces/index" see? When you switch to PREFIX mapping like having mappings start "/faces/whatever", you must skip the .jsp extension so your index.jsp file should contain:
 
<jsp:forward page="/faces/tbrowser"/>
 
Adding the .jsp suffix while using prefix mapping is causing your problem (that plus how your web.xml Servlet and Filter mappings are setup). I strongly recommend you to back to the myfaces blank.war and example war files to see how standard *.jsf suffix mapping works and begin your application with that style until you are positive you can make a working JSF application.  It will save you time and effort since searching (the web or this lists's archives) on the *.jsf SUFFIX extension will result in a much greater number of relevant posts than if you use PREFIX "/faces/*" mapping.

I have a project folder that looks like:
 
/transactionbrowser/
- WEB-INF
- resources
-index.jsp
-tbrowser.jsp
 
 
With the servlet-mapping of:
 
<filter>
    <filter-name>MyFacesExtensionsFilter</filter-name>
    <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
    <init-param>
        <param-name>maxFileSize</param-name>
        <param-value>20m</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>MyFacesExtensionsFilter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
<filter-mapping>
    <filter-name>MyFacesExtensionsFilter</filter-name>
    <url-pattern>/faces/myFacesExtensionResource/*</url-pattern>
</filter-mapping>
 
<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
</servlet-mapping>
 
 
The only URLs that work are:
 
 
 
On my index.jsp I have:
 
<jsp:forward page="/faces/tbrowser.jsp"/>
 
 
So, when I go to:
 
 
I see the page, but not with the MyFaces rendering, I still plain control GUI components with none of the add MyFaces filter files. How do I use jsp:forward properly to get to:
 
 
or
 
 
 
I can't use the following since that doesn't run the MyFaces servlet:
 
<jsp:forward page="/transactionbrowser/faces/tbrowser.jsp"/>
 
 
Thoughts or examples are appreciated.
 
Thanks,
 
--Todd
