Hi,
When I deploy a JSF+Facelets application into JBoss 4.2.2, it works fine: when I visit http://localhost:8080/project_name/home.faces the page is rendered correctly.
However, if I package it as an EAR and then deploy it, JBoss displays the following error message:
java.lang.LinkageError: loader constraints violated when linking javax/el/ELContext class
com.sun.facelets.el.ELAdaptor.getELContext(ELAdaptor.java:45)
com.sun.facelets.impl.DefaultFaceletContext.<init>(DefaultFaceletContext.java:85)

Are you deploying a Web project or an Enterprise Application project ?
An EAR project that only contains a simple WAR project (JSF 1.2 + Facelets / JavaEE 1.5)
Is there an expression language library in the packaged EAR that you are deploying? Is the commons-el.jar is present in JBOSS_DIR/server/default/deploy/jbossweb…./ ?
I will check that tomorrow. I am very zleepy right now 😉 I has to zleep 🙂 But just as a quick response, it is the default setup and I have not changed/modified anything. I expected it to work out of da box…
Having the same issue here. I’ve had a really difficult time getting JSF to work at all from MyEclipse. I guess I’m just not used to the “myeclipse way”.
It looks like the myeclipse facelets library (which includes the el- jars) is just not compatible with the JBoss implementation. To work around this, I removed the Facelets 1.1 library, and created a new JSF implementation library using the jars from /jboss/server/default/deploy/jboss-web.deployer/jsf-libs.
That builds and deploys and runs (so far) without any issues, but I’m afraid I’ll run into issues with the myeclipse tools later (this is a very simple test so far).
I was really hoping myeclipse would work for me. I’m trying to work up a prototype for my next project, but it’s not really working out very well so far. Should I be using something else for web UI?
Have you gone thorugh this tutorial to get an idea on how to create a JSF app with MyEclipse:-
