Composite components via portletfaces

[Alexey Truntov, módosítva 12 év-val korábban]

Hi, i'm using Liferay with JSF 2.0 and portletfaces 2.0.1 and trying to create composite component. Here's component itself:

<!--?xml version="1.0" encoding="UTF-8"?-->


	
<composite:interface />

<composite:implementation>
	<font size="20px">TEST</font>
</composite:implementation>
	

Component (xhtml) resides right in 'cz/bsc/g6/components/card/web/ui/component' directory in 'resources' folder. After compilation it goes to '../classes/cz/bsc/g6/components/card/web/ui/component'.

Here's using page:

<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:p="http://primefaces.prime.com.tr/ui" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:myutil="http://java.sun.com/jsf/composite/cz/bsc/g6/components/card/web/ui/component">
...
<myutil:button />
....
</ui:composition>

On rendering of using page i've got following exception:

13:33:51,262 ERROR [ResourceImpl:139] Resource handler=[com.sun.faces.application.resource.ResourceHandlerImpl@1ca87ea] was unable to create a resource for resourceName=[button.xhtml] libraryName=[cz/bsc/g6/components/card/web/ui/component] contentType=[null]

Could someone tell me what i'm doing wrong? It seems to be valid composite component usage for me.

Rather than having the resources live in the classpath, try putting your resources in src/main/webapp/resources/myutil

That's the way Example JSF2 portlet does it:
https://github.com/liferay/liferay-faces/blob/master/demos/bridge/jsf2-portlet/src/main/webapp/resources/

Also, the following view shows how the namespace is used:
https://github.com/liferay/liferay-faces/blob/master/demos/bridge/jsf2-portlet/src/main/webapp/views/applicant.xhtml

Like this:
xmlns:example-cc="http://java.sun.com/jsf/composite/example-cc

Many thanks, Neil, it works.

Now we have problems on Weblogic.

Composite components are found in project wars and correctly rendered on page, but when any server requests initiated on page with composites we get following errors in WLS logs and all those requests fail.

Any ideas are greatly appreciated.

PS: i've tried to turn on optimistic synchronization in WLS, but the error still persist.

Hi Alexey,

Sorry for the late reply but somehow I missed your post. First, I would recommend upgrading to Liferay Faces Bridge. If you still get the NotSerializableException in WebSphere AS, then please checkout the source from Git and have the PortletContainerLiferayImpl class implement Serializable. Also add a serialVersionUID field. If that fixes it, then let me know and we can add that.

Neil

Thanks, Neil. We'll try your solution later.
