Configuring Facelets into Seam

fleury May 10, 2007 10:57 AM

Hey,

I have some troubles to configure a custom facelet tag library.

Configuration files :

faces-config.xml :

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE faces-config PUBLIC
"-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
"http://java.sun.com/dtd/web-facesconfig_1_1.dtd">

The TaskFormLibrary class :

package cns.genoscope.console;

import com.sun.facelets.tag.AbstractTagLibrary;
import com.sun.facelets.tag.TagLibrary;

import javax.faces.context.FacesContext;
import javax.faces.application.Application;

public final class TaskFormLibrary extends AbstractTagLibrary {
public TaskFormLibrary() {
super("http://jbpm.org/jsf/tf");

final FacesContext facesContext = FacesContext.getCurrentInstance();
final Application application = facesContext.getApplication();

// Task form environment setup
application.addComponent("org.jbpm.tf.TaskForm", "org.jbpm.webapp.tag.tf.ui.TaskForm");
addComponent("taskForm", "org.jbpm.tf.TaskForm", null);

// Task form include tag
addTagHandler("includeTaskForm", IncludeTaskFormHandler.class);

}
}

Thanks

Odd, I think you have a classloading problem. Is the TaskFormLibarary in the war classes? Check you don't have more than one copy of facelets.jar hanging around.

Why not just use xml to set up your components?

Thank you Petemuir for your help

I'm using Jboss server (jboss-4.0.5.GA) and my TaskFormLibrary class appears only in the subdirectory jar of the exploded-archives folder, with the other classes of my session beans but not in the war subdirectory. Found no copy of facelets.jar.

Why not just use xml to set up your components?

Could you show me how to use xml for my tag library ?

Thanks

Petemuir, I'm coming back to this point :

Check you don't have more than one copy of facelets.jar hanging around.

I have a jsf-facelets.jar file in the lib directory and this declaration in my application.xml file :

jsf-facelets.jar

Is this the right configuration ?
If i remove this declaration, i get the expected exception :

java.lang.NoClassDefFoundError: com/sun/facelets/tag/AbstractTagLibrary

pmuir May 10, 2007 12:05 PM (in response to fleury)

You need to have jsf-facelets.jar in WEB-INF/lib (stuff *will* break otherwise) and if you want to do the ClassLibrary in code, you'll need to make sure its on the war classloader.

https://facelets.dev.java.net/nonav/docs/dev/docbook.html#taglib-create (or look at the jboss-seam-ui.jar/META-INF/*.taglib.xml for an example) - the xml way of declaring tags is *much* easier.
