richfaces configuration with spring web flow

[braduk]

Hi all,

I'm trying to get richfaces working with spring web flow on JBoss 5.1. After lots of configuration issues I think I'm nearly there but I'm having trouble getting the richfaces tags to render. Basically the tags weren't being expanded, they'd just come back in their original raw form.

I think that problem may have been due to my faces-config.xml which was missing the view handler. So I added that:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">

     <application>
          <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
     </application>     

</faces-config>

Once I add the view handler section I get this error:

2009-12-16 10:15:14,071 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/test]](main) Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener

Can anyone tell me where I'm going wrong? I'm pretty keen to get this working.

Thanks,

Brad.

Hi Brad,

Looks like you have conflicting versions of EL-API in your application and application server.

Hi Nick,

thanks for answering.

I tried using the el-api.jar that comes with JBoss 5.1 in C:\java\jboss-5.1.0.GA\common\lib. That gives me the same error:

Cause: Class 'org.richfaces.component.ClonedObjectResolver' is not an instance of 'class javax.el.ELResolver'

If I remove el-api.jar from my WEB-INF/lib I get:

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoClassDefFoundError: com/sun/el/ExpressionFactoryImpl

Looking at the maven config info in the docs at

 http://docs.jboss.org/richfaces/3.3.2.GA/en/devguide/html/GettingStarted.html

I see it lists

http://repository.jboss.com/maven2/javax/el/el-api/1.0/el-api-1.0.jar

....I tried that one too and got the error about ClonedObjectResolver. Any ideas?

.

Ok that was fixed by removing el-api.jar from WEB-INF/lib and adding in el-ri.jar. I tried my test page and got a NullPointerException:

ERROR  [compiler] Missing Built-in Tag Libraries! Make sure they are included within the META-INF di
rectory of Facelets' Jar
ERROR  [viewhandler] Error Rendering View[/home.xhtml]
java.lang.NullPointerException
     at com.sun.facelets.compiler.NamespaceHandler.apply(NamespaceHandler.java:49)
     at com.sun.facelets.compiler.EncodingHandler.apply(EncodingHandler.java:25)

I upgraded to the jsf-facelets.jar from jboss-seam-2.2.0.GA as described in this page:

http://seamframework.org/Community/JBoss5AndFacelets

......and it works!

Thanks for your help Nick.
