Custom JSF StateManager

Hi
Is there any commercial Database StateManager that store the views and views state in the database instead of session
or detailed tutorial for creating custom StateManager
any help will be appreciated
Thanks you and have a good day.

Pretty sure there isn't any such thing, since this is going to completely murder performance.

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.

Problem Adding Custom JSF Components to Oracle JDeveloper 10g (10.1.3) Prev

I'm having a problem on Adding Custom JSF Components to Oracle JDeveloper 10g (10.1.3) Preview (http://www.oracle.com/technology/products/jdev/101/collateral/101/adffaces/howto_customcomponents.html)
The step 1 of 5 isn't visible for me and I don't see the "Install from local file" option to select the adf-faces-bundle.zip from my file system. The OTN check for updates don't prove the ADF Faces...
What may I do?

Customized JSF clientid question

Dear all,
In the jsp jsf codes, I have the following customized component
<dojo:dojoComboBox dojotype="dijit.form" binding="#{backing_GWANADD.dojoComboBox2}" id="dojoComboBox2"/>
<a4j:commandButton binding="#{backing_GWANADD.commandButton1}"
id="commandButton1" action="backing_GWANADD.makeResult" reRender="dojoComboBox2" value="submit"/>
where dojo:dojoComboBox is customized components and a4j is the ajax4jsf component (command button).
Please pay attention on a4j tag, attribue "reRender" was used to urge the component with id dojoComboBox2 to re-render data from backing bean.
When I run the application, there is error that the id "dojoComboBox2" could not be found, showing the id of customized control is not dojoComboBox2.
When I change the id from dojoComboBox2 to id0, it works. How can I change the ID from id0 to dojoComboBox2 ?
If the id is not change from _id0 to the id that I set, I am not able to make use of the component id to do something.
So, change customized jsf id is important to me. How to do it? Thank you.

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.

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:
<?xml version='1.0' encoding='windows-1252'?>

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

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?

YUI Tabs with Custom JSF

Has anyone ever done anything with YUI Tabs and custom JSF presentations? I'm having an issue where a YUI dataSrc'd tab will not load in my JSF page.
Here are some contextual details...
I have the following directory structure configured:
- customJSP
-- proposal.jsf
- webResources
-- js
--- proposal.js
-- includes
--- testInclude.jsf
In proposal.jsf, I load proposal.js using a webResource tag - <script type="text/javascript" src="<fuego-type-lib:webResources relativePath='js/proposal.js' />"></script>. It loads fine.
In proposal.js, I have a YUI tab component that I want to load another page -
var tabs = new YAHOO.widget.TabView();
tabs.addTab(new YAHOO.widget.Tab({label: '<span class="tabTitle"> <br />Tab 1</span>',content: 'Loading... Please wait.',dataSrc: '<jsp:include page="<fuego-type-lib:webResources relativePath="includes/testInclude.jsf" />" />',cacheData: false}));
I have tried to include testInclude.jsf using <% @include file="<fuego-type-lib:webResources relativePath="includes/testInclude.jsf" />". I even moved all files into the same directory and used straight relative paths, e.g. <% @include file="testInclude.jsf' %> and <jsp:include page="testInclude.jsf" />.
testInclude.jsf looks like this:
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="jsf-html" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="jsf-core" %>
<%@ taglib uri="http://fuego.com/jsp/ftl" prefix="fuego-type-lib" %>
<%@ taglib uri="http://fuego.com/jsf/components" prefix="fuego-component" %>
<div id="summaryTabContent" class="tabContent">
This is a test page that should be displayed as an include.
</div>
All I see when I access this tab is the, "Loading... Please wait," message.
I know YUI uses AJAX to display the dataSrc'd tab content. Any thoughts?

I discovered the issue. It has to do with what YUI expects for the path of dataSrc'd pages. It expects an escaped path, e.g. ..//path//to//file which the webResource tag doesn't render properly. I ended up hard-coding the path to the file as ..//webRoot//webResources//includes/testInclude.jsf. It works now; however, the question becomes, is there any issue caused by hard-coding the path to the file in this manner?

Exception handling in custom JSF components

Hi,
Im trying to develop a JSF custom component, intended for professional use ;-)
I want to ask you for a definitive and solid way to handling exceptions in the encode/decode methods.
JSF books dont say too much about that.
For example, if your code may produce an ArrayIndexOutOfBoundsExceptions, how will you handle it? Will you use FacesException, JSFException, JSPException, ServletException, or what?
I find two interesting discussions concerning this, but I want to hear expert voices:
http://forums.sun.com/thread.jspa?forumID=427&threadID=528752
http://forums.sun.com/thread.jspa?forumID=427&threadID=528227
Thanks!

You should in fact never explicitly catch RuntimeExceptions or Errors, unless you have a really, really good excuse. RuntimeExceptions are a sign of a "developer error" and needs to be bugfixed by just adding solid prechecks, so let them go. Errors are in any way unrecoverable, so let them go as well.
To avoid ArrayIndexOutOfBoundsException just add a precheck on the array length and so on.

Generating script tag from Custom JSF Tag

Hi,
I am new to JSF Custom Tags. I developed a Custom tag. It's quite a fun to make your own custom tags . Now I have to use some javascript for my custom components. The inline javascript calls are no issue for me. But I want my javascript be embedded in a <script> tag automatically. So that I don't have to explicitly add my javascript into <script> tag, instead, it is automatically included in the page where my tags are being used. How can this be achieved?
Regards,
Kashif

Anchors don't have a type="submit". You should be basing this on an h:commandLink. In fact you could probably rewrite it all as an XML tag that just generates an h:commandLink.

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

Trying to custom JSF created with NetBeans 5.5

Hello,
I'm trying to create an enterprise application using JSF new technology. I have find an easy way to do this with NetBeans 5.5 with SJSAS 9.0.
I have an Apache Derby database connected and configurated with my enterprise application. I have created the Entity Classes from this database. JSF pages from Entity Classes are generated and persistence unit is configured successfully. All this steps had maked using NetBeans methods. I have feel a lot of tutorials and guides.
When I play the enterprise application, a list of classes appears and you can obtain a list of the objects loaded into database of the selected class. When you have obtained this list of objects, you can create a new object or database row, you can view data of a selected object and finally edit this data.
OK, now I would like to custom this JSF structure created with NetBeans. For example, I would like to call New.jsp page from any JSF class, from index.jsp. Always this error appears:
java.lang.IllegalStateException: No FacesContext is available to process this request. This is most likely due to the request being sent to the wrong path.
The same error I have obtained trying to copy-paste code from a JSF Page generated with NetBeans, the same exception appears only pasting this pice of code:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

</head>
<body>
<f:view>
<h1><h:outputText value="JavaServer Faces" /></h1>
</f:view>
</body>
</html>
A way to solve this exception is using a JSF configuration. I have look for info about JSF configuration but I don't know how to configure faces-config.xml file. It seems is file where are configurated JSF enviroment: converted, managed beans and navigation rules are configurated by NetBeans.
Could you please help me to custom this JSF NetBeans code?
Or a tutorial or guide where JSF NetBeans 5.5 code is used with an enterprise application SJSAS 9.0 and a Apache Derby database.
I have look for any example or possible solution during weeks but, I can't find anything that I can use to custom NetBeans code. All examples are too basic and never use an enterprise application.
Thank you a lot!
Kind regards,
Ricard

I'm sorry for my english, I explain better I know.
Anyone understand my question? May you offer an example or guide or tutorial about this?
Thank you!

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.
