问题
I am familiar with the classloading trouble when using JSF 2 in Websphere 7. I'd like to know if there are similar problems on other fullstack application servers. What about JBoss 5+, WebLogi 10+, etc? Are there any known issues with JSF 2 and if so, what needs to be done to get JSF 2 running on these servers?
Thx

On WebSphere 5.x up to with the current 8.x you need to set the WAR and EAR classloader to PARENT_LAST in the WAS admin console whenever you want to bundle and use your own JSF impl in /WEB-INF/lib.
On JBoss 4.x up to with the current 6.x it's sufficient to add the following context param to /WEB-INF/web.xml to suppress JBoss' builtin JSF deployer.
<context-param>
<param-name>org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL</param-name>
<param-value>true</param-value>
</context-param>
On Glassfish 2.x up to with the current 3.x you need to add the following entries to the /WEB-INF/sun-web.xml (Eclipse with Glassfish plugin should autogenerate the template file if you create a web project with target runtime set to Glassfish).
<class-loader delegate="false" />
<property name="useBundledJsf" value="true" />
On Weblogic, sorry I have no idea, I have never used it.

In WebLogic there is a shared Java EE library that is included with WebLogic for JSF 2.0. It is easy to use and referenced through a deployment descriptor.

Here is a brief how-to for the library concept Jeff mentioned. http://blog.eisele.net/2009/07/jsf-20-beta-1-on-oracle-weblogic-10gr3.html
Seeing the latest WLS 12c it still is in place but AFAIK you will end up having to revert the web-app classloader in the future in favor of this concept.
