Hi Gavin, Thank you for your reply. I want to try to integrate the tomahawk.jar in JBoss to see whether it works. I plan to copy the tomahawk.jar into "C:\jboss-4.0.4.GA\server\default\deploy\jbossweb-tomcat55.sar\jsf-libs", but I don't know how to modify the web.xml file in the "\jboss-4.0.4.GA\server\default\deploy\jbossweb-tomcat55.sar\conf". The modification seems to be similar to myfaces-impl.jar integration: web.xml: | ... | <init-param> | <description>MyFaces tlds</description> | <param-name>tagLibJar0</param-name> | <param-value>jsf-libs/myfaces-impl.jar</param-value> | </init-param> | ... Could you please give me some guidance on web.xml, which seems like, perhaps: <init-param> | <description>Tomahawk tlds</description> | <param-name>????</param-name> | <param-value>jsf-libs/tomahawk.jar</param-value> | </init-param> Thank you so much.
