[jboss-user] [JBoss Seam] - about custom tags

[dago]

i try to add a custom tag by facelets:(down example code from https://facelets.dev.java.net/servlets/ProjectDocumentList?folderID=3635&expandFolder=3635&folderID=0)

JsfCoreLibrary.java:
package com.arcmind.jsfquickstart.tags;

import com.sun.facelets.tag.AbstractTagLibrary;

import java.lang.reflect.Method;
import java.lang.reflect.Modifier;


/**
 * JsfCoreLibrary is an example for IBM developerWorks (c).
 * @author Rick Hightower from ArcMind Inc. http://www.arc-mind.com
 */
public final class JsfCoreLibrary extends AbstractTagLibrary {
    /** Namespace used to import this library in Facelets pages  */
    public static final String NAMESPACE = "http://www.arc-mind.com/jsf/core";

    /**  Current instance of library. */
    public static final JsfCoreLibrary INSTANCE = new JsfCoreLibrary();

    /**
     * Creates a new JstlCoreLibrary object.
     *
     */
    public JsfCoreLibrary() {
        super(NAMESPACE);

        this.addTagHandler("setValueBinding", SetValueBindingHandler.class);
        this.addTagHandler("isBoolean", IsBooleanHandler.class);
        this.addTagHandler("isText", IsTextHandler.class);
        this.addTagHandler("isDate", IsDateHandler.class);

        try {
            Method[] methods = JsfFunctions.class.getMethods();

            for (int i = 0; i < methods.length; i++) {
                if (Modifier.isStatic(methods.getModifiers())) {
                    this.addFunction(methods.getName(), methods);
                }
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}


jsf-core.taglib.xml:
<?xml version="1.0"?>

<!DOCTYPE facelet-taglib PUBLIC
  "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
  "facelet-taglib_1_0.dtd">

<facelet-taglib>
	<library-class>
           com.arcmind.jsfquickstart.tags.JsfCoreLibrary
      </library-class>
</facelet-taglib>


i get this result:
