Problem with booking-portlet-faces sample (from SWF 2.0.3 Released)

**minimarmotte** · Aug 8th, 2008, 07:30 AM

Hi !

I try to run the booking-portlet-faces sample from SWF 2.0.3 Released.

I use Tomcat 6.18 and Apache Pluto Portal 1.1.15.

I generate a war with Maven and deploy it into Tomcat without errors !

With Pluto Admin, I add the portlet to the main page.
When the portlet is rendered , I have this error :

Code:

javax.portlet.PortletException: Request processing failed
	at org.springframework.web.portlet.FrameworkPortlet.processRequest(FrameworkPortlet.java:496)
	at org.springframework.web.portlet.FrameworkPortlet.doDispatch(FrameworkPortlet.java:453)
	at javax.portlet.GenericPortlet.render(GenericPortlet.java:175)
	at org.apache.pluto.core.PortletServlet.dispatch(PortletServlet.java:208)

...

Caused by: org.springframework.webflow.execution.FlowExecutionException: Exception thrown in state 'intro' of flow 'view'
	at org.springframework.webflow.engine.impl.FlowExecutionImpl.wrap(FlowExecutionImpl.java:568)

...

Caused by: java.lang.ClassCastException: org.apache.pluto.internal.impl.PortletContextImpl

	at org.springframework.faces.webflow.JsfViewFactory.getView(JsfViewFactory.java:73)
	at org.springframework.webflow.engine.ViewState.doEnter(ViewState.java:189)
...

Any idea on the ClassCastException: org.apache.pluto.internal.impl.PortletContextImpl ?

Thanks !!

And I have the same problem with Liferay 5.1.0 Bundled with Tomcat 6.0 :

Code:

Caused by: java.lang.ClassCastException: com.liferay.portlet.PortletContextImpl

I have run into the same issue with the Apache MyFace JSR-301 Portlet Bridge. It is still very much in the alpha stages.

The sample apps work with the JSR-301 implementation from https://jsfportletbridge.dev.java.net/.

Please let me know if you continue to have issues.

Thanks for your help !

I took a look at JSF Portlet Bridge, but I don't understand how to apply it, sorry

First, I add th librairy jsf-portlet :

Code:

<dependency>
  <groupId>com.sun.faces.portlet</groupId>
  <artifactId>jsf-portlet</artifactId>
  <version>1.2.3</version>
  <scope>compile</scope>
</dependency>

Then I guess I have to modify portlet.xml ?
I change

Code:

<portlet-class>
  org.springframework.web.portlet.DispatcherPortlet
</portlet-class>

to

Code:

<portlet-class>com.sun.faces.portlet.FacesPortlet</portlet-class>

And normally I have to add :

Code:

<init-param>
  <description>Portlet init view page</description>
  <name>com.sun.faces.portlet.INIT_VIEW</name>
  <value>?</value>
</init-param>

But I don't know what value I have to use

Maybe I'm complety wrong ?

All you need to do is drop the jar onto your classpath. The config should be automatic.

I did what you told me : just add the jar !
And it works very well !!!

Thanks a lot Scott

Hi!

I had exactly the same problem as described above. After adding the dependency to jsf-portlet-1.2.3.jar however, I get a different ClassCastException:

I'm using spring-web-flow 2.0.4.RELEASE, Liferay 5.1.2, Maven2, OSX 10.5.
I have left the portlet.xml and web.xml unchanged.
Any ideas what might cause this error?

I got the same ClassCastException with Liferay Portal. Does anybody have a solution for this problem?
