Custom JSF Component tags ignored after converting to Facelets layout

I am currently using JDeveloper 10.1.3.3.
I have a project consisting of .jspx pages. These pages mainly use components from ADF faces core. I also created my own custom JSF component that I use in several of these pages.
Then, I needed to use Facelets so that I could apply a standard layout to all my .jspx pages. I looked at all the tutorials, and I created a layout.xhtml for my .jspx pages to use. This worked great for my .jspx pages that don't have my custom JSF component.
Now, when I run my page with my custom component <img:newimage ...etc >
the tag is ignored and it appears in the page's source as is when it should render as <img.src=...etc>. Attributes of newimage are changed on the page appropriately like width and height, but my component's tag, component, and servlet java files are never accessed.
How can I fix this? Please help!
Thanks.

Hi,
did you post this issue to the Facelets open source site ? Sounds like an issue with using Facelets

Create a custom JSF component

Hi,
I want to create a custom JSF component. I've setup a new application containing 2 projects:
- a 'components' project, containing all the custom components
- a 'view' project, to test the created custom components.
There is dependency between the components project and the view project. In the view project, I added the
the Tld, in order to use my components in the project.
From the component palette, I can drop a component onto a .jspx page but after running the page, no output
is printed onto the screen. The HTML source code only contains my 'tag-name' (eg: <ctb:mytag/>)
Am I doing something wrong?
UIComponent:
import java.io.IOException;
import javax.faces.component.UIComponentBase;
import javax.faces.context.FacesContext;
import javax.faces.context.ResponseWriter;
public class BasicComponent extends UIComponentBase {
    public String getFamily() {
        return "BasicComponent";
    public void encodeBegin(FacesContext context) throws IOException {
        ResponseWriter out = context.getResponseWriter();
        out.write("Hello World");
}Tag
import javax.faces.component.UIComponent;
import javax.faces.webapp.UIComponentTag;
public class BasicComponentTag extends UIComponentTag {
    public String getComponentType() {
        return "BasicComponent";
    public String getRendererType() {
        return null;
}Tld entry:
<tag>
    <name>BasicComponent</name>
    <tag-class>BasicComponentTag</tag-class>
    <body-content>JSP</body-content>
</tag>Thanks in advance,
Koen Verhulst

The body tag should be as follows
<bodycontent>JSP</bodycontent>
but the JSP will not work. Here is the file:

Creating a custom JSF Component

Hi,
I am trying to create a custom JSF Component. My ultimate goal is to pass a bean to my custom component and have the component render some HTML output based on the info contained in the bean. Before I attempt that I am trying to get a simple custom component to just work. This component is based on the tutorial found here: http://www.jsftutorials.net/components/index.html
This tutorial just creates a component that outputs a <div> tag around the body contents of the custom component.
To keep this short I have done the following items from the tutorial link above:
1) I have created the tld file defining the tag class, name, uri and shortname
2) I have also created the tag class called TickerTag.java along with the component class UITicker.java. These classes are straight copy-and-paste jobs from the tutorial link and compile fine.
3)My faces-config.xml file has the proper component definition of
<component>
<component-type>ticker</component-type>
<component-class>ticker.UITicker</component-class>
</component>
This was the easy part. The example then goes on to use the custom component in a JSP page. I managed to get the custom component to work in a JSP page BUT my problem is getting the custom component to work in an XHTML file.
I thought all I had to do was define an xml namespace using the uri from my tld file like so:
Note: My uri is www.fubar.com/tags and is defined in the tld file.
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:t="http://myfaces.apache.org/tomahawk"
xmlns:u="http://www.fubar.com/tags">
I then try to use the tag like so <u:ticker> <f:verbatim>Hello JSF Component</f:verbatim></u:ticker>
I am expecting the following output: <div>Hello JSF Component
</div>
but instead I get
<u:ticker>Hello JSF Component</u:ticker>
It seems the tag is not even processed. This is my first jump into custom components. I have done custom JSP tags in the past but I never tried to display them on an XHTML page.
If you are wondering why I am using XHTML pages, this was setup a while back by a previous developer. Changing everything to a JSP would take a long time and probably break some stuff I am not aware of yet. As such the web.xml file of this JSF web app has the following:
<context-param>
<param-name>javax.faces.DEFAULT_SUFFIX</param-name>
<param-value>.xhtml</param-value>
</context-param>
So all *.jsf files are processed and sent to the corresponding .xhtml file.
I have looked up creating custom components on google and every last example uses their newly created components in a jsp file. No XHTML uses so far.
Below are my tld files and xhtml file if that helps:

Thanks Ray. I'll take a look at that site.
I managed to figure out my problem. I never created a .taglib.xml file that reference the component I defined in the faces-config.xml file. Once I did that everything work perfectly.
I managed to use this forum post as a guide.

I hope this helps anyone else.

How to add properties to a custom JSF component?

Hello, everybody!
I've just developed my first custom JSF component. It's a data pager and it is working pretty well. But now I want to be able to use some of it attributes in my backing beans at runtime. I mean, I want to bind it to component in the JSF page. It already has a binding attribute in the tld file, but I want to be able to accesss two values that the renderer of my custom component calculate inside it, which would relieve me from calculating these values manually in the backing beans. So, I would like to know how to make these values external to the component.
By now this is my custom pager class:
import javax.faces.component.UICommand;
public class UIPaginadorDados extends UICommand
}You can see that it has no logic because all the logic is in the renderer class:
import javax.faces.render.Renderer;
public class PaginadorDadosRenderer extends Renderer
// logic here
}As I said I want to be able to do the following in my backing beans:
private UIPaginadorDados pager = new UIPaginadorDados();
// and later...
pager.getCurrentPage();
pager.getPageCount();In the JSF page:
// I already can do this, because I have a binding attribute
<urca:paginadorDados binding="#{backingBean.pager}" />I suppose that I'll have to create the properties getCurrentPage() and getPageCount() in the component class, UIPaginadorDados, but I don't know how to get the values to the properties from the renderer class. I don't even know if this is how I should do it.
So I would appreciate a lot your help about this subject.
Thank you.

Custom JSF component with custom value datatype

I've created a simple custom JSF component with a decode, encodeBegin as follows:
public void decode(FacesContext context) {
    Map<String, String> requestParameters = context.getExternalContext().getRequestParameterMap();
    String clientId = getClientId(context);
    String value = requestParameters.get(clientId);
    setSubmittedValue(value);
    super.decode(context);
public void encodeBegin(FacesContext context) throws IOException {
    ResponseWriter response = context.getResponseWriter();
    String clientId = getClientId(context);
    response.startElement("input", this);
    response.writeAttribute("name", clientId, "id");
    response.writeAttribute("type", "text", null);
    String value = (String) getValue();
    if (null != value) {
         response.writeAttribute("value", value, "value");
    response.endElement("input");
}With also:
setRendererType(null);as part of the constructor.
This component works just fine both inside and outside of a dataTable component, as expected.
What I would like to do now is to replace the String value datatype with a custom class, for example MyDataType. For this I do:
public void decode(FacesContext context) {
    Map<String, String> requestParameters = context.getExternalContext().getRequestParameterMap();
    String clientId = getClientId(context);
    String value = requestParameters.get(clientId);
    MyDataType myData = (MyDataType) getValue();
    MyDataType newData = (MyDataType) myData.clone();
    newData.setValue(value);
    // copy old object and only update the changed field of this object
    setSubmittedValue(newData);
    super.decode(context);
public void encodeBegin(FacesContext context) throws IOException {
    ResponseWriter response = context.getResponseWriter();
    String clientId = getClientId(context);
    response.startElement("input", this);
    response.writeAttribute("name", clientId, "id");
    response.writeAttribute("type", "text", null);
    MyDataType value = (MyDataType) getValue();
    if (null != value) {
         response.writeAttribute("value", value.getValue(), "value");
    response.endElement("input");
}Now this works perfect outside of a dataTable component, but inside it fails to update the property on the BB.
Are there somewhere examples on how to properly use custom datatypes as values for UIInput components? Also how to only partially update the value (like I do, I only want to update the value field of the MyDataType object)

Even if I encode the entire MyDataType via hidden input elements and decode it again (i.e. not using a cloned getValue) it's still not working side a dataTable.
Could it have to do something with me using Facelets?

Question about creating Custom JSF form tag and renderer

Is it possible to build a custom form tag in JSF and have it replace the standard jsf form tag. Are there any potential issues with child forms or anything else.
I created the following
- custom form component class that extends javax.faces.component.UIForm (the only changes I made was to change the value of the COMPONENT_TYPE attribute and change the value for renderer type)
- custom form renderer class that extends HtmlBasicRenderer and I made changes to the encodebegin method and encrypt the value of the id and action url)
- custom form tag class that extends UIComponentELTag ( I did not make any changes here)
- tld for my custom form tag
- created an entry in faces-config.xml of my web-app for my custom form tag
Are there any issues with the above.
Is there something I should do in addition.

In theory you should be fine. Some of the open source libraries either swap out the renderer for the standard h:form component or supply their own form components. You could look at their code for reference if need be.

Customer JSF Component Value Expression not work

why my customer tag not work,
in my jsp
<q:my formatString="yyyy/mm/dd" current="#{LoginBean.date}"></q:my>the isLiteralText() always return true, and I can't get the correct value, #{LoginBean.date} is returned.

                component.getClass().getName() +" is no UIDatePicker");
        component.setValueExpression("current", current);
        System.out.println(current.getExpressionString());
        System.out.println(current.isLiteralText());
        System.out.println((String) component.getAttributes().get("current"));
     * @return the formatString
    public String getFormatString() {
        return formatString;
     * @param formatString the formatString to set
    public void setFormatString(String formatString) {
        this.formatString = formatString;
    private ValueExpression current;

        return current;
     * @param value the value to set
    public void setCurrent(ValueExpression current) {

I do not know what your native is, but there's quite a huge difference between "custom" and "customer". Look it up in your dictionary.

JSF Component Tag Localization

In resource file if I have "." (dot) in between the key name then how to change the code below,
For eg,
Search.Value = Search Now
Working Code:
<jsfc:loadBundle basename="res.Resource" var="resource" />
<jsfc:view>
<jsfh:command_button id="btnSearch" value="#{resource.SearchValue}">
<jsfh:output_text value="#{jsfresource.SearchValue}" />
</jsfc:view>

Since <loadBundle> loads resouce bundle in as a map, change your code as follows:
<jsfh:output_text value="#{jsfresource['Search.Value']}" />

Custom AS3 Component / Event Definition for MXML Tag

Custom AS3 Component / Event Definition for MXML Tag
Exposing custom event in custom MXML tag.
I have made an AS3 custom component named,
'CustomListComponent'.
Is a list type component extending UIComponent.
When an item is clicked (selected) I generate a custom event
named, 'selChange'
I want the user to be able to use this tag, define a handler
on the MXML tag.
I tried using metadata like [Event("selChange")] in the
component AS3 file with no luck.
Any help / examples to expose a custom event from an AS3
custom component to the MXML tag for the end user/developer would
help significantly.
Anyone? Thank you.

Well, That did not take long.
My mistake, Typo type.
[Event(nane="selChange", type="flash.events.Event")]
That is: naNe not naMe :(
Thank you all for your time and responses.
I WILL check my code more closely next time I post a
question.
P.S.: @VarioPegged : My code is big and not needed now. If
you would like it anyway just message me. TY

GetStyle() of JSF component before render

Hey guys,
I'm hoping this is an easy one, here goes...
For one reason or another, I need to modify the CSS of certain components in a JSF page before it is rendered to the browser. The JSF pages are going to be laid out in Netbeans 6.0 (beta right now) using mostly Woodstock components and will have the 'style' attribute filled in for each component. However, like I said, I want to modify the CSS style value of some components prior to rendering.
Looking through the Javadocs for Woodstock (javadocs are included with plugin) I see that many components do indeed give you access to this attribute ('style'), com.sun.webui.jsf.component.Field.getStyle() returns "CSS style(s) to be applied to the outermost HTML element when this component is rendered" for example.
I figured this would be straight forward enough and attempted to retrieve the style using the prerender() method. Unfortunately, getStyle() returned null. After playing around with it for a while, it appears as though the components do not get these properties set (by the Netbeans attribute) until DURING the renderResponse phase. I say this because I tried setStyle() during prerender() and my changes were ignored. I then went back to Netbeans and removed my 'suggested style', now my setStyle() call during prerender() holds showing that somewhere in the renderResponse phase (after prerender()) the style is being set if one is given.
Obviously making any changes after prerender() [like in afterRenderResponse()] will not cut it.
To sum up:
Even as late in the lifecycle as prerender(), the CSS style attribute of a Woodstock component is not yet set (getStyle() returns null and setStyle() ends up being overwritten). Any suggestions on how to modify the style?
Thanks in advance (and I hope this is an applicable forum),
Sean

Solved:
Once I wrapped my head around the problem I found a much more elegant solution.
What I wanted to do was relatively position page fragments but was having trouble as the Netbeans IDE positions components within fragments absolutely. To make my page dynamic I was taking the style="position: absolute" attribute out of the <div> tag that was holding the <jsp:directive-include>. The components within the fragments were then being positioned absolutely on the resulting page, ending up strewn all over the place. This led me off on the tangent to reposition the components when the page was called (original post above).
The weekend did me well I suppose. I came up with the bright idea to CHANGE the style attribute on the <div> tag rather than remove it. Making the <div> component "position: relative" passed its positioning down the the containing components and now my fragments are displayed correctly while being dynamically repositionable.
Hope this helps anyone coming across the same problem.

Just extended my first jsf component. but in the right way?

Hi all,
After days of trial and error, i finally managed to code my own JSF component, extending existing infrastructure. Since things just suddenly fell in place during a brute force approach to make it work, i'd like to ask for opinions of seasoned JSF veterans whether this makes sense or there is a better way to do things.
The objective was to be able to render a collection of items as a comma separated list. To this end, I took an existing data iterator UIComponent from richfaces, added a custom renderer -- again extending on richfaces, and hooked things up in 2 config files, as follows:
CsvRenderer.java:
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.context.ResponseWriter;
import org.ajax4jsf.component.UIDataAdaptor;
import org.richfaces.renderkit.AbstractRowsRenderer;
import org.richfaces.renderkit.TableHolder;
/** Renders a richfaces UIDataList component as a comma separated list */
public class CsvRenderer extends AbstractRowsRenderer {
     @Override
     public void encodeOneRow(FacesContext context, TableHolder holder)     throws IOException {
          UIDataAdaptor table = holder.getTable();
          ResponseWriter writer = context.getResponseWriter();
          renderChildren(context, table);
          if(holder.getRowCounter() < table.getRowCount() - 1) {
               writer.write(", ");

Custom faces component not rendering at runtime

I'm new to the JSF Framework. So I thought that starting a custom component/tag library would be a good start to jump in and get familiar with it. My goal is to have a project separate from my web-apps that I could compile into a jar which I could include wherever I needed it. So I started simple with two projects: the first is the custom tags project, the second is a simple webapp using jsf / facelets / seam which I am running in a Tomcat 5.5 container.
I've included the complete projects in a zip file here: http://burtoncarl.com/share/CustomProof.zip
I build the components project with ant and include it in the /WEB-INF/lib folder of the web project. But when I open a browser to the web app it doesn't render my tag at all. It leaves my new tag in the rendered HTML which leads me to believe that the parser isn't matching my taglib or something.
And of course I get no errors in any of the log files.
ANY help would be appreciated...

It sounds like the component library is not registered on the page. Assuming you are using facelets, did you define an xmlns for it? E.g. see the definition for the tomahawk library below within the facelet xhtml file:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:t="http://myfaces.apache.org/tomahawk">
    
</html>You also need to tell facelets about the library in the web.xml:
    
    <context-param>
        <param-name>facelets.LIBRARIES</param-name>
        <param-value>
            /WEB-INF/tomahawk.taglib.xml
        </param-value>
    </context-param>

JSF component inside HTML table -- not rendering properly

I have a HTML table like the one below. In one of those columns (td) I have a JSF component. When I run the app, the JSF component (even if its a simple inputText or panelGrid or panelGroup) is not getting inside the td. Instead, it forms a seperate table after this td.
Code I have:
<table border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td>... ..MULTIPLE Td's here - Deleted for simplicity </td>
<td class="topNav">
Blog Directory
</td>
<td>
<img src="./images/top_button_right.gif"/>
</td>
<td class="topNav">
<f:panelGroup>
<h:inputText value="Username"/>
<h:inputSecret value="Password"/>
</f:panelGroup>
</td>
</tr>
</tbody>
</table>
What I expected:
username, passwd field inside the top level HTML table.
What comes: (as a result of running thsi JSF page )
<table> -- Original table
<td> </td> -- -TD that had the inputText - comes empty here
</table>
<table>
<tbody>
<tr>
<td><input type="text" name="_id1:header:EasyHeader:_id4" value="Username" /><input type="password" name="_id1:header:EasyHeader:_id5" value="" /></td>
</tr>
<tr>
<td><table>
I am a newbie to JSF & due to the complexity of the layout & page, I m unable to get rid of the HTML tags totally.
Thanks in advance.
Ganesh

Found the solution to the problem.
wrapped the entire HTML page till the JSF component ( panelGrid) under <f:verbatim>.
something like this
<f:verbatim>
<table>
<tr> <td>...</td>
<td>
</f:verbatim>
<h:panelGrid> ... </h:panelGrid>
<f:verbatim>
</td>
</table>
</f:verbatim>

Tomcat and refreshing jsf component attributes in the browser

I'm using Eclipse and Tomcat 5.0.25. I start Tomcat in debug mode with a shortcut: "C:\Tomcat-5.0\bin\catalina.bat jpda start". I have an entry in the Tomcat server.xml file that points to my web application:
<Context debug="0" docBase="C:\MyProjects\eclipse\cdstore\WebContent" path="/cdstore" reloadable="true"/>
I have a jsp page with a jsf dataTable tag. If I change the html markup (i.e. by typing "hello" in the jsp page) and press the refresh button in my IE 6.0 browser, the "hello" message is displayed.
If, however, I change the content of a dataTable attribute (i.e. I change styleClass="aClass" to styleClass="anotherClass") or add a new dataTable attribute, the attribute changes are not sent to the browser when I press the browser refresh button. I do a "view html source" and they are not there.
I have to close the browser down and relaunch the browser to see the new dataTable attributes.
Does anybody know if there is any easier way of doing this?
thanks, jeff

Hi pushpa latha
Yes it is possible to update the data at the header level using below approach
create the component interface for your cusotm component
use the component interface in the header overview standard component as resuable component.
Implement the event handler method for the button , in the event handler method get the refreshed value
create the navigation and call the navigation (fire_outbond_plug) to cutom component by passing the plug name and refreshed data..
set the refreshed data to your value node in your custom component.
Thanks & Regards

How to build custom JSF components?

The JSF tutorials demonstrate ways to build JSF web "applications" ...
I am interested in developing JSF web "components" ... Is there any resource that I can avail of or if it's possible for some of u to share a sample ...
thanks much,
keyur

Hi Keyur,
The tutorial does need to include a custom component example. We have been working on an example and it's just about done. We need to work out some bugs, get it working on the RI that is publicly available, and document it.
If you need to get started in the meantime, here are some basic steps for creating a custom component:
1. Write a tag handler class that extends javax.faces.webapp.FacesTag. In this
class, you need:
* a getRendererType method, which returns the name of your custom renderer, if
you are using one (explained in step 4).
* a createComponent method, which returns an instance of your custom component.
* an overrideProperties method, in which you set all of the new attributes of
your component.
2. Create a TLD that associates the custom tag to the tag handler.
3. Write a class that either extends a standard JSF component or extends directly from javax.faces.component.UIComponentBase.
If a standard JSF component has most of the functionality you need, you can extend the component class that defines this component. These classes are found in the javax.faces.component package. Otherwise, extend UIComponentBase.
4. Either create a custom renderer by extending javax.faces.render.Renderer, or include the rendering code in one of the encodeXXX methods of your custom
component class. From the encodeXXX method, use the ResponseWriter from FacesContext to write out the markup. If what you need to render is fairly
simple, it's easier to include the rendering code in the component class.
5. From your ServletContextListener instance, register your Renderer to the standard RenderKit by: using RenderKitFactory to get the RenderKit, and using
addRenderer on the RenderKit to add your new Renderer. You only need to do this if you created a Renderer in step 4.
6. Declare your new TLD in your JSP page and use the tag in the page.
This will all be clearer once we publish the custom component documentation. We are working on it presently and will announce its release on this forum.
Thank you for your interest in JavaServer Faces
