A nice alternative to specifying the taglib using the web.xml is to pack the component in a separate jar-file and to include the taglib within the META-INF folder. Only condition: the taglib-name must follow the pattern XXX.taglib.xml.
Nice sideeffect: all xhtml-artifacts are read from the jar-file!!! works smoothly regards Alexander -----Original Message----- From: kindsol [mailto:[EMAIL PROTECTED] Sent: Thursday, November 30, 2006 6:29 PM To: MyFaces Discussion Subject: Re: Using custom JSF-Components with Facelets You also need to tell facelets to look at your custom-taglib: Add to web.xml something like: <context-param> <param-name>facelets.LIBRARIES</param-name> <param-value>/WEB-INF/custom-taglib.xml</param-value> </context-param You can add more files to the param-value, just separate each file by a semicolon.
