Can Seam be configured to support JSP and Facelets in an ap

[gfzhang]

Hi,

We are trying to port our web application to Seam.

We want to use Facelets to newly developed pages and port the existed JSP pages to Facelets in the future.

I replace javax.faces.DEFAULT_SUFFIX in context-param with facelets.VIEW_MAPPINGS:

 <context-param>
 <param-name>facelets.VIEW_MAPPINGS</param-name>
 <param-value>*.xhtml</param-value>
 </context-param>

but the sample application won't work.

Could anyone kindly tell me if it is possible or how to do it?

Thanks for your help very much!

I'm curious about this as well.

[cptnkirk]

Yes it is. Set your facelets.VIEW_MAPPINGS like you have done and use prefex matching for the JSF servlet.

<servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
 <url-pattern>/faces/*</url-pattern>
</servlet-mapping>

You can then go to either /faces/somepage.jsp or /faces/somepage.xhtml.

Hello

I've changed booking example to use jsp, but I'm getting the following error:

After changing the servlet mapping according to CptnKirk's instruction, The modified sample works well.

You please try:

 <filter-mapping>
 <filter-name>Seam Redirect Filter</filter-name>
 <url-pattern>/faces/*</url-pattern>
 </filter-mapping>

and

 <!-- Faces Servlet Mapping -->
 <servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
 <url-pattern>/faces/*</url-pattern>
 </servlet-mapping>

I do not know why the program failed when using"/*" as the url-pattern. It can not work here either. It display the same error message as you reported.

I don't think JSF supports that....

I've tried your suggestion but in't work well for me.
From http://localhost:8080/seam-booking/ got redirected to http://localhost:8080/seam-booking/home.seam where I got 404 error:

HTTP Status 404 - /home.jsp

type Status report

message /home.jsp

description The requested resource (/home.jsp) is not available.
Apache Tomcat/5.5.17

[gfzhang]

I modify the booking sample as described above. I did not create any jsp files, so I use the files provided by the sample, that is, use xhtml as the suffix. It works.

try

http://localhost:8080/seam-booking/faces/home.xhtml

or change index.html to

<html>
<head>
 <meta http-equiv="Refresh" content="0; URL=faces/home.xhtml">
</head>
</html>

[cptnkirk]

You'll have an easier time starting a new JSF project from scratch.

* Make the above changes and create two files in your web root. test.jsp and test1.xhtml.
* Have one use JSP/JSF and the other Facelets/JSF.
* Then navigate to /faces/test.jsp and /faces/test.xhtml.

Both JSF pages should render.

Guofeng,

It's working now. Thank you for your help!

Hi everyone,

I have a similar problem. I have tried your solutions, but it doesn´t work. My problem is that when I have a datatable in a portlet, and I want to see another page of the datatable, it redirect to faces/home.xhtml, and I don´t want that ir redirect to faces/... because I have my views in webapp directory.

Sorry very much, for my english.

Mi web.xml is as follows:
