desperate : help required with webflow/faces and grails 2.0.3

[will.woodman]

folks desperate for some help

i'm a closet grails user - and i was trying to get JSF working with grails. the JSF2 plugin doesnt work at all under 2.0

tried a different tack and built myself a plugin and tried to use mojarra, and cut and pasted webflow 2.3.1. sample stuff into my plugin

this fails completely in embedded tomcat 7 dev mode see this posted on grails forum
http://grails.1312388.n4.nabble.com/...td4568248.html

i get an error like this

| Error 2012-04-18 17:02:39,390 [pool-6-thread-1] ERROR [localhost].[/aGflow]  - StandardWrapper.Throwable
java.lang.IllegalStateException: Could not find backup for factory javax.faces.context.FacesContextFactory.
        at javax.faces.FactoryFinder$FactoryManager.getFactory(FactoryFinder.java:1008)
        at javax.faces.FactoryFinder.getFactory(FactoryFinder.java:343)
        at javax.faces.webapp.FacesServlet.init(FacesServlet.java:302)
...

however when i generate a seperate WAR built in grails and deploy to tomcat 7 my static and facelet page renders of (saw something about problems with mojarra outsid of a WAR)

so in desperation i tried MyFaces instead and got further - but still doesnt work

so here goes. In my buildConfig i have this

   repositories {
        grailsCentral()
        mavenRepo "http://tomcat.apache.org/dev/dist/m2-repository"
        // uncomment the below to enable remote dependency resolution
        // from public Maven repositories
        //mavenCentral()
        //mavenLocal()
        //mavenRepo "http://snapshots.repository.codehaus.org"
        //mavenRepo "http://repository.codehaus.org"
        //mavenRepo "http://download.java.net/maven/2/"
        //mavenRepo "http://repository.jboss.com/maven2/"
    }
    dependencies {
        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg.

        // runtime 'mysql:mysql-connector-java:5.1.5'
		compile 'org.springframework.webflow:spring-webflow:2.3.1.RELEASE',
			'org.springframework.webflow:spring-faces:2.3.1.RELEASE',
			//'org.springframework.security:spring-security-core:3.1.0.RELEASE',
			'org.springframework:spring-webmvc:3.1.1.RELEASE',
			'org.apache.myfaces.core:myfaces-api:2.1.7',
			'org.apache.myfaces.core:myfaces-impl:2.1.7'

    }

in my doWithWebDescriptor closure in the plugin i add the webflow/faces bits into the web.xml as per the 2.3.1 documentation

	static def  doWithWebDescriptor (def xml)
	{

		/** 
		 * Spring web root context 
		 */
		def envParams = xml.'context-param'[0]
		/* grails already sets this for us 
		envParams + {
		  
			'context-param' {
			  'param-name'('contextConfigLocation')
			  'param-value'('/WEB-INF/applicationContext.xml')
			}
		} */
		
		def listenersList = xml.'listener'
		def listeners = listenersList[listenersList.size() - 1]

		
		listeners + {
			  listener {
				'listener-class'('org.apache.myfaces.webapp.StartupServletContextListener')
			  }
		  } 

		/**
		 * JSF2 Implementation
		 * 
		 */
		envParams + {
			
			  'context-param' {
				'param-name'('javax.faces.DEFAULT_SUFFIX')
				'param-value'('.xhtml')
			  }
			  'context-param' {
				'param-name'('javax.faces.PROJECT_STAGE')
				'param-value'('Development')
			  }
			  'context-param' {
				'param-name'('javax.faces.FACELETS_REFRESH_PERIOD')
				'param-value'('1')
			  }
		  }
  
		println "add faces servlet"
		def servletsList = xml.servlet
		def servlets = servletsList[servletsList.size() -1]

		// load the Faces servlet
		servlets + {
			servlet {
			  'servlet-name'('Faces Servlet')
			  'servlet-class'('javax.faces.webapp.FacesServlet')
			  'load-on-startup'('1')
			}
		}

		def mappingsList = xml.'servlet-mapping'
		def mappings = mappingsList[mappingsList.size() - 1]
			mappings + {
				  'servlet-mapping' {
					'servlet-name'('Faces Servlet')
					'url-pattern'('*.faces')
				  }
			  }
	
		/**
		* MVC Implementation
		*
		*/
			println "add MVC servlet"
			servletsList = xml.servlet
			servlets = servletsList[servletsList.size() -1]
	
			// load the Faces servlet
			servlets + {
				servlet {
					'servlet-name' ('springmvc')
					'servlet-class' ( 'org.springframework.web.servlet.DispatcherServlet')
					'init-param' {
						'param-name' ('contextConfigLocation' )
						'param-value' ('/WEB-INF/spring/appServlet/servlet-context.xml' )
					}
				'load-on-statup' ('1')
				}
			}
	
			mappingsList = xml.'servlet-mapping'
			mappings = mappingsList[mappingsList.size() - 1]
				mappings + {
						'servlet-mapping' {
						'servlet-name'('springmvc')
						'url-pattern'('/app/*')
					  }
				  }
	
		println "final web.xml config looks like :"
		println renderFormattedXML (xml)
		return xml
	}

If i run this in standalone tomcat it works and my /app/home facelets page is rendered

if i run this in embedded tomcat mode it fails

details in reply post below - the first time i posted this said it was too long - so here goes for part 2

[will.woodman]

ok part 2 .

here is my generated web.xml

Caused by IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

I dont want to have to give up dev mode working in STS and have to export to WAR all the time. What is going on and how can i fix it

really appreciate some fresh eyes and some help on this its driving my barmy

yours in advance

[will.woodman]

I think its something to do with grails run-app and its packaging - as well as doing stuff in your workspace under STS something happens round the back of the file system in C:\Users\802518659\.grails\2.0.3\projects\aflowMyf acesPlugin


so run i try and do a run app - it creates a web.xml.tmp file

this a web.xml formatted file - but if you look at it doesnt have the additions i have written through the doWithXMLDescriptor closure in the plugin descriptor file

where are is if you generaate a war with run-war - it builds an 'xml' file the war.web-inf directory and this does have additions included .

so when your then deploy that war on tomcat externally which i did it kind of works - at least it serves my /app/home facelet page

whereas if i do a run-war in embedded working as opposed to run-app i get an error like this

WARNING: No mappings of FacesServlet found. Abort initializing MyFaces.
| Error 2012-04-21 22:40:12,486 [pool-6-thread-1] ERROR [localhost].[/aflowMyfacesPlugin]  - StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

	at javax.faces.FactoryFinder.getFactory(FactoryFinder.java:206)
	at javax.faces.webapp.

would be intereted is anyone know what this is doing - i'll post back over at the grails forum also
