Thanks Leonardo. I've managed to work out how to bypass it: I set the org.apache.myfaces.CHECK_EXTENSIONS_FILTER value to false (I basically read the source code to find what I needed to do) to tell tomahawk to not validate the filter configuration. This neatly side-steps the issue.. although if you *do* want validation, it doensn't help much :)
Essentially I just added the following to my web.xml: <context-param> <param-name>org.apache.myfaces.CHECK_EXTENSIONS_FILTER</param-name> <param-value>false</param-value> </context-param> Cheers, Rob Leonardo Uribe <[email protected]> 30/03/2010 03:03 PM Please respond to "MyFaces Discussion" <[email protected]> To MyFaces Discussion <[email protected]> cc Subject Re: ConnectionException validating XML using t: panelTabbedPane [SEC=UNCLASSIFIED] Hi javax.servlet api jar should provide this dtd (maybe your web container is not providing this dtds). In this case tomahawk try to get it, but it "can't see it". Try put this file under your webapp classpath: javax/servlet/resources/web-app_2_3.dtd That should work. The other alternative is override the EntityResolver used by tomahawk to parse the document, to provide the file necessary to be resolved. regards, Leonardo Uribe 2010/3/29 <[email protected]> > Hi, > > I'm trying to use the Tomahawk panelTabbedPane tag on a project that > already has some working tomahawk (tomahawk 1.1.9; jsf 1.1; java 1.6) > tags.
