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

[Todd Patrick]

OK, this is making sense;

 

I downloaded the blank.war file and I am installing it now - in the meantime, I went back and changed

 

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

 

to:

 

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

 

Now, I receive:

HTTP Status 404 - /transactionbrowser/tbrowser
type Status report
message /transactionbrowser/tbrowser
description The requested resource (/transactionbrowser/tbrowser) is not available.

My servlet-mapping is still:

 

<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>

 

 

Thanks,

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:

 

http://127.0.0.1:8080/transactionbrowser/faces/tbrowser.jsp

http://127.0.0.1:8080/transactionbrowser/faces/

 

 

On my index.jsp I have:

 

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

 

 

So, when I go to:

 

http://127.0.0.1:8080/transactionbrowser/

 

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:

 

http://127.0.0.1:8080/transactionbrowser/faces/

 

or

 

http://127.0.0.1:8080/transactionbrowser/faces/tbrowser.jsp

 

 

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,
