I have seen this exception, but in my case is was always due to an error on my
part and disappeared after I fixed it.
I am currently using Seam 1.2.1 on JBAS 4.2.1 in production.
I will switch to Seam 2.0 as soon as it comes out though.

I am seeing exactly the same bizzare behavior. My app works fine (s:hasRole()
apparently working since my menu.xhtml is evaluating ok), until I click on a
Save button (though oddly, I can click Delete on the same form without any
trouble). Exception at the bottom of this post.

In hopes that this is a clue to one of the Seam developers (specifically
Michael Yuan who seems to have done quite a bit of porting to various new
environments and may recognize the symptoms):

Can you try with the latest CVS version of Seam? I believe we made some
changes after 1.2.1 to fix this.

Thanks Shane,
I don't doubt that this is fixed in 2.0 or CVS latest, but I can't easily
migrate my app to the new Seam config. I'd hoped to be able to do a partial
migration of a still Seam 1.2.1-based app, but running with JSF 1.2 (we've had
some problems that appear fixed by the newer JSF) -
Yeah, the problem with the examples for the book is that security is the last
chapter to be added to the book just before it goes off to the printers. So, I
did not have a runnable example application in the source code bundle to test
out the security annotations. My apologies to my readers!
All,
Good news: I just noticed that Chiral posted a followup to my post on Michael's
blog explaining the bug and proposing a workaround:

I was too quick when I said it works. It works most of the time, but not all
the time. I get errors like:
javax.faces.FacesException: javax.el.ELException: /layout/menu.xhtml @12,51

It seems to be happening when I invoke an action from that page by clicking a
button, which hits some action in my FooHome extends EntityHome object. I can
research this some more if it would help.

And it looks like the problem is in org.jboss.seam.util.EL:
| import com.sun.el.ExpressionFactoryImpl;
| import com.sun.el.lang.VariableMapperImpl;
|
which means that Seam is still dependent on the Sun EL RI, while JBoss AS has
switched, and packaging the Sun RI in the EAR causes
Further checking, the Sun RI is used in only two files in Seam:
./main/org/jboss/seam/util/EL.java:import com.sun.el.ExpressionFactoryImpl;
| ./main/org/jboss/seam/util/EL.java:import
com.sun.el.lang.VariableMapperImpl;
| ./main/org/jboss/seam/jsf/SeamELFunctionMapper.java:import
I think you may need to have that JAR around.
FWIW, this all works fine in the upcoming Seam 1.3.

It seems like that jar would mess up other things. Reading Michael Yuan's blog:

There is now a JIRA open on it:
Yes - Seam 2.0. I got confused. :)

By the way this shows why classes which are not public should not be labeled
public. My guess is that com.sun.el.*Impl should have default permissions so
external projects couldn't specify them directly.

Let me clarify: the el-*.jar entires in application.xml mess up things. It does
not hurt to leave the JARs in the EAR/WAR classpath -- at least this is what I
think ...

When I put the jars in the war/WEB-INF/lib, I get:

Can you try to put just the implementation classes not the interfaces in the
lib dir? Thanks.

I put el-ri.jar in the WEB-INF/lib, and got the same
java.lang.NoClassDefFoundError: com/sun/el/ExpressionFactoryImpl.
I then put the el-ri.jar directly in the ear, and added it as a module in
application.xml, and... it works! I tested it and it lets me run the

Is this AS 4.2.1 GA?
Thanks

I looked some more and the missing class is defined in el-ri.jar . But I
thought that that jar should no longer be used in JBoss 4.2.1. This means that
some Seam class is compiled to look for the com.sun.el.ExpressionFactoryImpl
class. Is there a work-around for this?
Everything else is
