Hi Gavin, I found a post in Seam forum (I remember I ever saw it, but could not find it before) about the integrating tomahawk.jar into JBoss, and modification to the conf/web.xml as follows:<init-param> | <description>MyFaces tlds</description> | <param-name>tagLibJar1</param-name> | | <param-value>jsf-libs/tomahawk.jar</param-value> | </init-param> I will try it tonight to see whether it works. Thank you. Gus View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959716#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
