Seam Remoting java.lang.NoClassDefFoundError: com/sun/el/Exp

Paul Sideleau Newbie

I am testing the seam remoting feature on JBOSS 4.2 with seam 1.2.1 ga. I have a bean with bijection annotations that use el expressions to inject the proper object. I get the following error when a remote method is called.:

For example:

@Name("test")
public class Test implements Serializable
{
@In(#{someBean.property})

@WebRemote
public void test()
{
// some code
}
}

Is this a bug or am I not supped to use el-expressions and/or bijection for beans that are to be accessed remotely?

Thank you.
