Hi,
I want to built a custom render kit for SVG. I put in faces-config.xml the
following
<render-kit>
<render-kit-id>SVG</render-kit-id>
<renderer>
<component-family>javax.faces.Command</component-family>
<renderer-type>rendersvg.Button</renderer-type>
<renderer-class>rendersvg.CommandButtonTag</renderer-class>
</renderer>
others renders
....
</render-kit>
I use this renderkit in the following jsp:
<?xml version="1.0"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd";>
<%@ page contentType="image/svg+xml"%>
<%@ taglib uri="http://java.sun.com/jsf/svg"; prefix="g" %>
<%@ taglib uri="http://java.sun.com/jsf/core"; prefix="f" %>
<svg xmlns="http://www.w3.org/2000/svg";
xmlns:xlink="http://www.w3.org/1999/xlink";>
<style type="text/css">
rect:hover {fill-opacity:0.3;}
</style>
<f:view renderKitId="SVG" >
<g:form id="form">
<g:outputText x="100" y="50" textAnchor="middle" value=".xxx..."
style="stroke:black; stroke-width:0.5; fill:none;
font-size:32pt;" />
....................
</g:form>
</f:view>
</svg>
I wrote the renderers (this is one example)
public class ButtonRenderer extends Renderer {
..........
public void decode(FacesContext context, UIComponent component) {
............
}
public void encodeBegin(FacesContext context, UIComponent component)
throws IOException {
..........
}
public void encodeEnd(FacesContext context, UIComponent component)
................
}
}
I wrote the tag clases
public final class CommandButtonTag extends UIComponentELTag {
..........
public String getRendererType() {
return "rendersvg.Button";
}
public String getComponentType() {
return "javax.faces.Command";
}
..........
}
But when I start tomcat I get
Apr 24, 2009 4:38:21 PM org.apache.myfaces.config.FacesConfigurator
configureRenderKits
SEVERE: failed to configure rendersvg.CommandButtonTag
java.lang.ClassCastException: rendersvg.CommandButtonTag

What do you think I am missing?
