Hello. Hope this is the right place to post (seems like jboss el is part of the seam project). I would like to use JBoss EL as a standalone EL provider. Is this possible? I'm using Tomcat 6, JSF 1.2 and Facelets. I've tried putting the el jars in /lib folder, but I'm getting this error: java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.addELResolver(Ljavax/el/ELResolver;)V" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, org/apache/myfaces/webapp/DefaultFacesInitializer, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ELResolver used in the signature Can't find much information about this on the net. --- View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075986#...
