Custom component/renderer deploy "location"

What is the best place to deploy custom components/renderers sources inside the war archive? Under WEB-INF ?

I would group them in a JAR file and place it in /WEB-INF/lib.

How to get jsp PageContext in custom component renderer

Hi,
How to find PageContext(javax.servlet.jsp.PageContext) form within the custom component renderer class?
Please help?
Thanx & Regards
Milind

Strictly you're looking which URL has invoked the new request? With other words, you want the referrer?
If so, doString referrer = request.getHeader("referer"); // Yes, with the legendaric misspelling.Be careful with this, the client has full control over what he/she sends with the headers, so also the referrer. It might be null or changed while you didn't expect that. If you want to be safe, you may consider to send the current URL as a hidden parameter along with the request.

Controlling custom component rendering

As I'm writing my own custom components, I've come across some behaviorisms of JSF that don't quite make sense to me. I thought I'd ask the group, and see if someone can clarify it.
Let's say I've got a JSP with the following components on it:
<myfaces:comp1>
<myfaces:comp2>
<myfaces:comp3/>
</myfaces:comp2>
</myfaces:comp1>
Let's assume that the UIComponent representing comp2 contains the following snippets:
public boolean getRenderChildren() {
return true;
public void encodeBegin(FacesContext context) throws IOException {
// render something here....
public void encodeChildren(FacesContext context) throws IOException {
Iterator iter = this.getChildren();
while (iter.hasNext()) {
UIComponent child = (UIComponent)iter.next();
child.encodeBegin(context);
if (child.getRenderChildren()) {
child.encodeChildren(context);
child.encodeEnd(context);
public void encodeEnd(FacesContext context) throws IOException {
// render something here....
All the other components return false for getRenderChildren();
During the Rendering Phase, I find that comp3
is actually rendered twice.
This is an oversimplification of the code I was experimenting with, but what puzzled me was the fact that whatever class is traversing the various components during Rendering Phase does not seem to check whether a component is going to render its children itself, and as it comes to that child component (in this case, comp3), it renders it anyhow. Then when comp2's encodeChildren() method is called, it too renders comp3.
I suspect I may misunderstand how these methods are used..

During the Rendering Phase, I find that comp3
is actually rendered twice.
This is an oversimplification of the code I was

check whether a component is going to render its
children itself, and as it comes to that child
component (in this case, comp3), it renders it anyhow.
Then when comp2's encodeChildren() method is called,
it too renders comp3.Yes, Suns reference implementation does not seem to check whether a component's parent has set the "encodeChildren" attribute to true.
Well, the open source implementation "MyFaces" (http://sourceforge.net/projects/myfaces/) does this.
What's not so clear is the following question:
When a component is rendered by it's parent and itself has the "encodeChildren" attribute set to false, should children of this component automatically be rendered, or not? In other words: Whenever a component has the "encodeChildren" attribute set to true, is it responsible for rendering all children and grandchildren (and grand-grandchildren...)?
The final Specification should state this clearly, I think.

Excpeption creating custom component

Hi all,
I'm using Sun's RI 1.2 to create a custom component that consist of
standard components. My problem is that this custom component renders
ok but when I submit the form that contains it I get an
IndexOutOfBoundsException.
Can anyone please tell me what's causing this or what's the problem?
Here's the exception:

Hi,
I had a little trouble find a maven repository serving the RI jars but eventually I found one:
       <dependency>
         <groupId>javax.faces</groupId>
         <artifactId>jsf-impl</artifactId>
         <version>1.2-b19</version>

         <artifactId>jsf-api</artifactId>
         <version>1.2_02</version>
       </dependency>By the way, I had this problem with the myfaces 1.2 implementation too.
Thanks for your help,

Range component in custom item renderer

Hi,
I am trying to put a spark Range component into the labelItemRenderer for flex mobile. Everytime I add it I get the error: "Skin for (long directory name for my range component) cannot be found". The custom item renderer is an actionscipt class because I read this is the best way to make them for mobile. I'll put the error in the bottom of the post.
If anyone has any idea why this could be happening or if anyone knows a possible way around this it would be extremely helpful. I basicaly just need a list where each item has a label on side and then a progress bar on the other side.
Thanks.
Here is the full error, ill put a star on the line where the addChild method gets called in my item renderer for the range component.

Customizing ADF component rendering

Hi,
I'm trying to override some ADF component rendering in order to provide some clients with a simple application appearance. To do so, in faces-config.xml:
<pre>
<render-kit>
<render-kit-id>oracle.adf.core</render-kit-id>
<renderer>
<component-family>oracle.adf.Panel</component-family>
<renderer-type>oracle.adf.Page</renderer-type>
<renderer-class>com.mycompany.web.faces.renderer.MyPanelPage</renderer-class>
</renderer>
</render-kit>
</pre>
I define MyPanelPage class that extends javax.faces.render.Renderer class. I override encodeBegin, encodeEnd, encodeChildren and getRendersChildren methods and it works fine. However, I run into a problem when I want to make the renderer work "in default mode" (the way it ussually works) under certain condition. I suppose that there might be a special render class used by "oracle.adf.core" render kit to render panelPage component, which determines the location of every facet. Anybody know which is this class.
Thanks in advance.
Luis Serrano.

How do you reference a valueObject located in main to a custom component created in Catalyst?

Hello,
I have been working with the Catalyst Beta 2 / Flash Builder beta trying to create a photogallery and have hit a little bit of a snag, try as I might I can't seem to find the answer anywhere. I am still new to Flex so please excuse me if this is a basic question, I have been trying to understand more about Flex to make my designs in Catalyst better.
I found this video on Adobe TV: http://tv.adobe.com/watch/rich-internet-applications-101/ria-stepbystep-16-binding-a-data- service-to-flash-builder-components/
It's wonderful and I have the datalist I created in Catalyst working with the XML file I generated but I designed my little photogallery a bit diffrent, I created a Custom Component in Catalyst so that when you click an item on the DataList it pop's up a little screen with a larger photo in on it, rather then having an image in the main application. Now my problem seems to be that I can't refrence the valueObject I created with the wizard as it's in my Main.mxml file, is there a way to refrence it from my Custom Component so the larger image will display? Is there a way to let the component know which item on the dataList in the main application is selected and display the correct image?
I should also say I really enjoy working with the Beta for both Flash Builder / Catalyst, thanks for the hard work!
Thanks for the help,
Chris

I am afraid you cannot bind to static properties in Windows Store Apps. It is simply not supported.
You could create a proxy class that exposes the static command property and bind to this property of an instance of the proxy object:
http://stackoverflow.com/questions/14186175/bind-to-a-static-field-in-windows-8-xaml
http://stackoverflow.com/questions/4708711/how-can-i-use-the-xstatic-extension-for-phone7-silverlight-apps
You will of course have to create an instance of the proxy object. There is no way around this.
Please remember to mark helpful posts as answer to close your threads and then start a new thread if you have a new question.

After deploying Custom Component BO Analysis Adaptive Server would not Start

Hello all,
I just developed my custom component in Design Studio with SDK and uploaded this component to BI Enterprise 4.1 SP2 Patch 3 server . After that, I tried to restart the Adaptive Processing Server which includes Analysis Service. However, the server would not start and it fails. If I uninstall the component and restart the server, it starts and works smoothly.
I have installed the same components to other BI servers without having any problems.
Do you guys have any idea what could be causing this?
Thanks in advanced.

Zahid,
Check if this line is added to the command line of the server holding the DS Server.
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
I had a similar problem, openned a support ticket and that solved it.

Custom Resource Renderer not coming on Implementing Flexible UI Components

HI,
I am using the Sneak Preview NW2004s SP9 with TREX .
I have to modify the search result list as returned by the TREX using the default search, basically have to include a custom Link based on the resource name.
I am trying to run the examples from the Knowledge Management and Collaboration Developer's Guide - "How to Implement Flexible UI Components".
I deployed the par file for the sample application "Using Flexible UI Ready-Mades"
and followed the steps as outlined below:
System Administration>System Configuration>Knowledge Management -->Content Management
1) Under
User Interface->Mapping>Resource Renderer
Created a new mapping for the java class com.sap.km.ui.renderer.SimpleResourceRenderer
2) Then under
User Interface->Settings>Resource Renderer Settings
Created a duplicate of SearchResourceRenderer
and in the copy changed the Resource Renderer to the custom one(as the one mapped in previous step).
In the Search Result layout Set, i changed the Resource Renderer Name to the custom one.
Now i restarted the server.(i tried restarting after almost all the steps )
But my resource renderer is not coming after i execute the TREX Search.The list returned seems to use the default Resource Renderer.
I even tried by making an advanced copy of the Search Layout Set, changed the Resource Renderer name, updated the OTH file(search.oth), Switched on the degugging for the WdfProxy and reloaded the OTH.
Now the new layout Set is being used but still i cannot see the result as per the custom resource renderer.
Morover, if i try to print some message from the resource renderer code(Component render method), it is not printed in the default Trace file.
Please help me in identifying and resolving the problem.
Thanks,
Siddhartha

Hi Detlev,
Sorry for the delay.
We don't want to exlude the folders, we would like keep it, the problem is, instead of appearing the folder name, is displayed the error message and below the actions (details, delete, ).
At first, we thought that could have been an error in the configuration of LayoutSet, but then, we tried on other two environments, with the default LayoutSet configuration and we still get, on the three environments, the same error message.
Any idea?
Thanks and Regards,
John

Custom component problem

I wrote a custom component:
Here is the code for the UIComponent:
package customcomponents;
import javax.faces.component.*;
import javax.faces.context.*;
import java.util.Vector;
import jsf.*;
public class UIEventsTable extends UIComponentBase {
     public String getFamily() {
          return "EventsTable";
     public void encodeEnd( FacesContext context ) throws java.io.IOException {
          Vector<Event> events = (Vector<Event>) this.getAttributes().get("events");
          ResponseWriter writer = context.getResponseWriter();
          writer.startElement("table" , this );
          for( int i = 0 ; i < events.size() ; ++i ) {
               writer.startElement("tr",this);
                    writer.startElement("td",this);
                         writer.write( events.elementAt(i).getEvent_description() );
                    writer.endElement("td");
               writer.endElement("tr");
          writer.endElement("table");
}This is the tag class
package customcomponents;
import javax.faces.webapp.*;
import javax.faces.component.*;
import java.util.*;
import jsf.*;
public class EventsTableTag extends UIComponentTag {
     Vector<Event> events = null;
     public String getRendererType() {
          return null;
     public String getComponentType() {
          return "EventsTable";
     public void release() {
          super.release();
          events = null;
     protected void setProperties( UIComponent component ){
          super.setProperties( component );
          if( events != null )
               component.getAttributes().put( "events" , events );
     public Vector<Event> getEvents() {
          return events;
     public void setEvents(Vector<Event> events) {
          this.events = events;

<d:EventsTable events="#{location.events}" />
...Now location.events is a java.util.Vector with the events. But when I use this tag I get following error message:
Servlet.service() for servlet Faces Servlet threw exception
org.apache.jasper.JasperException: Unable to convert string "#{location.events}" to class "java.util.Vector" for attribute "events": Property Editor not registered with the PropertyEditorManagerI do not understand why this doesn't work. Because in a "h:dataTable" I can tell the component to use an array as an input. Even more I don't know what a PropertyEditorManager is.
So how can I pass the vector object to this custom component?

Custom Property Renderer - class not found error?

Hi,
I am trying to create a custom property renderer in KM - just a basic Hello World for now, as in some of the other threads on SDN.
When I use the renderer for a property in my layout set, nothing is displayed.
My code is as follows:
public class SBPCPropertyRenderer extends AbstractPropertyRenderer
     public Component renderProperty(IProperty property, IResource res, int maxLength)
          throws WcmException
          TextView t = new TextView();
          t.setText("Hello World");
          return t;// renders a property
public interface IRFServiceWrapper extends IService
    public static final String KEY = "com.company.project.km.SBPCPropertyRenderer";
public class RFServiceWrapper implements IRFServiceWrapper
     private IServiceContext mm_serviceContext;
      * Generic init method of the service. Will be called by the portal runtime.
      * @param serviceContext
     public void init(IServiceContext serviceContext)
          mm_serviceContext = serviceContext;
          CrtClassLoaderRegistry.addClassLoader(this.getKey(), this.getClass().getClassLoader());
      * This method is called after all services in the portal runtime have already been initialized.
     public void afterInit()
      * configure the service : @param configuration
     public void configure(IServiceConfiguration configuration)
      * This method is called by the portal runtime when the service is destroyed.
     public void destroy()
      * This method is called by the portal runtime when the service is released.
     public void release()
     * @return the context of the service, which was previously set by the portal runtime
     public IServiceContext getContext()
          return mm_serviceContext;
      * This method should return a string that is unique to this service amongst all
      * other services deployed in the portal runtime.
      * @return a unique key of the service
     public String getKey()
          return KEY;
However, when I try to render using this bespoke renderer, I get the following error in the Default Trace:

Can anyone spot what I am doing wrong?

Hi Tom,
I've implemented similar behaviour but with the state of resource. The code is following:
private static final class URLs {
          private static final String BEFORE_APPROVAL = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledr.gif";
          private static final String APPROVAL = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledy.gif";
          private static final String PUBLISHED = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledg.gif";
          private static final String     ARCHIVED = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledi.gif";
     public Component renderProperty(IProperty property, IResource res, int maxLength){
          Image image = null;
          try {
               IRepositoryServiceFactory factory = ResourceFactory.getInstance().getServiceFactory();
               IURLGeneratorService ug = (IURLGeneratorService)factory.getService(IServiceTypesConst.URLGENERATOR_SERVICE);
               IStatemanagementManager stateManager = (IStatemanagementManager) factory.getRepositoryService(res,IWcmConst.STATEMANAGEMENT_SERVICE);
               IStatemanagementUtilsResource sResource = stateManager.getStatemangementResource(res).getUtils();
               Locale locale = res.getContext().getLocale();
               IState state = sResource.readState();
               if (state.getID().equalsIgnoreCase(States.BEFORE_APPROVAL))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.BEFORE_APPROVAL,null,null)).getPath(), state.getDescription(locale));
               if (state.getID().equalsIgnoreCase(States.ARCHIVED))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.ARCHIVED,null,null)).getPath(), state.getDescription(locale));
               if (state.getID().equalsIgnoreCase(States.APPROVAL))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.APPROVAL,null,null)).getPath(), state.getDescription(locale));
               if (state.getID().equalsIgnoreCase(States.PUBLISHED))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.PUBLISHED,null,null)).getPath(), state.getDescription(locale));
               return image;
          } catch (Exception e) {
               StatePropertyRenderer.log.fatalT(e.getMessage());
               return image;
But you can simply take one of the properties of your resource with the method res.getProperty(<IPropertyName>) instead of state and check the value of this IProperty. I took images from KM but you can also add necessary images to your project and use them.

Can't instantiate JSF Custom Component

I'm hoping some of you expert (or at least seasoned) JSF custom component developers might be able to lend some insight into the "Can't instantiate class" problem. I have a custom component which extends another component (which happens to be Oracle ADF's panelGroup), and I've verified that everything is in place:
1. Component class uses correct component type referenced by faces-config.xml and tag class
2. Renderer type referenced in faces-config.xml matches that of the renderer type in component class
3. There is a default constructor (no args) for the component class, which also sets the renderer type
4. TLD with tag is correct
All classes are definitely in the classpath, as I have another custom component in the same packages which loads and is used just fine.
Any ideas would be appreciated.
Thanks,
Shawn Bertrand

So, is no one else having any problems when using the new JSF components from Java Studio Creator 2 in their existing projects? I can make simple projects in Creator and run them on PointBase and Tomcat and can deploy and run from Eclipse using MyEclipse but I cannot get my existing project working and I am wondering if their is some sort of conflict between the new JSF components and legacy Struts stuff in that project or if perhaps Spring is someone interferering. Kind of at a loss right now...

Problem with inputText in my custom component

Hi, I have a custom dataTable component that I'm trying to get to work. It has to be a custom component because dataTable doesn't support rowspan, colspan, multi line headers, and a rendered attribute for rows. The problem is, that when I wrap the column tag inside my row tag then the method for the inputText tag never gets called in the UPDATE_MODEL_VALUES phase.
I'm starting to think that JSF doesn't support 2 levels of tags between the inputText and dataTable. I'm hoping that someone can tell me what I have wrong with my components.
Here is the JSP snippet.
<cjsf:rptTable>
     <cjsf:data id="dataTable1" value="#{allAuthUser.tableRows}" var="myTableRow1">
          <cjsf:row>
               <cjsf:col>
                    <h:inputText id="tableTestFld" value="#{myTableRow1.testFld}" size="5" maxlength="5"/>
               </cjsf:col>
          </cjsf:row>
     </cjsf:data>
</cjsf:rptTable>Here is what it renders. It looks to me like everything renders fine. So I'm guessing that there is something in a component that is causing JSF during the life cycle to not be able to process correctly.
<table>
     <tbody>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_0:tableTestFld" name="tblmaintForm:body:dataTable1_0:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_1:tableTestFld" name="tblmaintForm:body:dataTable1_1:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_2:tableTestFld" name="tblmaintForm:body:dataTable1_2:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
     </tbody>
</table>Note: If I leave off the row tag it renders the same way except of course the <tr> and </tr> tags are missing. If I do this, then the backing method for the inputText tag is called and everything works fine. Why doesn't it work with the row tag in place?
Here are the components:
public class UIRptTable extends UIComponentBase {
     public UIRptTable() {
          setRendererType("tblmaint.rptTableRenderer");
     public String getFamily() {
          return "javax.faces.Output";
public class UIRptTableData extends HtmlDataTable {
     public UIRptTableData() {
          setRendererType("tblmaint.rptTableDataRenderer");
     public String getFamily() {
          return "javax.faces.Data";
public class UIRptTableRow extends UIOutput {
     public UIRptTableRow() {
          setRendererType("tblmaint.rptTableRowRenderer");
     public String getFamily() {
          return "javax.faces.Output";
public class UIRptTableCol extends UIColumn {
     public UIRptTableCol() {
          setRendererType("tblmaint.rptTableColRenderer");
     public String getFamily() {
          return "javax.faces.Column";
}Here is part of the faces-config file in case you need it.

Hi, Ray!
1) I was trying to put a button in the column header (for sorting) and I couldn't get that to work. That involved the >colhdr tag. I got that to work but I don't remember the fix. I'll look it up and reply back with that when I can.Dealing the first part of your trouble, you need NOT a custom component.
I have looked through the implementation of RepeaterRenderer, as you advised me, and found that the multi-header possibility is included in the implementation of dataTable control.
The code below is the part of source of repeater.jsp with only change:
<d:data_repeater>  <h:dataTable>
And it works fine.
<h:dataTable id="table"
binding="#{RepeaterBean.data}"
     rows="5"
value="#{RepeaterBean.customers}"
var="customer">
<f:facet name="header">
<h:outputText value="Customer List"/>               <!� First Header row -- >
</f:facet>
<h:column>
<%-- Visible checkbox for selection --%>
<h:selectBooleanCheckbox
id="checked"
binding="#{RepeaterBean.checked}"/>
<%-- Invisible checkbox for "created" flag --%>
<h:selectBooleanCheckbox
id="created"
binding="#{RepeaterBean.created}"
rendered="false"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Account Id"/>               <!�Second Header row -- >
</f:facet>
<h:inputText id="accountId"
binding="#{RepeaterBean.accountId}"
required="true"
size="6"
value="#{customer.accountId}">
</h:inputText>
<h:message for="accountId"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Customer Name"/>               <!�Second Header row -- >
</f:facet>
<h:inputText id="name"
required="true"
size="50"
value="#{customer.name}">
</h:inputText>
<h:message for="name"/>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Symbol"/>
</f:facet>
<h:inputText id="symbol"
required="true"
size="6"
value="#{customer.symbol}">
<f:validateLength
maximum="6"
minimum="2"/>
</h:inputText>
<h:message for="symbol"/>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Total Sales"/>
</f:facet>
<h:outputText id="totalSales"
value="#{customer.totalSales}">
<f:convertNumber
type="currency"/>
</h:outputText>
</h:column>
<h:column>
<f:facet name="header">                    <!�Second Header row -- >
<h:outputText value="Commands"/>
</f:facet>
<h:commandButton id="press"
action="#{RepeaterBean.press}"
immediate="true"
value="#{RepeaterBean.pressLabel}"
type="SUBMIT"/>
<h:commandLink id="click"
action="#{RepeaterBean.click}"
immediate="true">
<h:outputText
value="Click"/>
</h:commandLink>
</h:column>
</h:dataTable>
You may have a look at HTML source to prove that dataTable is already what you need:
<table id="myform:table">
<thead>
<tr><th colspan="6" scope="colgroup">Customer List</th></tr>
<tr>
<th scope="col"></th>
<th scope="col">Account Id</th>
<th scope="col">Customer Name</th>
<th scope="col">Symbol</th>
<th scope="col">Total Sales</th>
<th scope="col">Commands</th>
</tr>
</thead>
<tbody>
2.) The second trouble is still unsettled as previously. Right now I have different task at my job, and I can�t continue investigation of this problem.
But when you find smth., please let me know. I�ll be very grateful.

Decode-method for custom component isn't called

Hi,
i have writen a custom component which gets some information by command-link. To make the data from the link accessible, i wrote a decode method in my renderer and in me component. But both method are not called from the faces framework.
Dows anybody knows what i made wrong???
Thanks, Sebastian

Hi,
thank you for your reply.
Unfortunately the processDecodes(...) of my component is also not called from the framework. Does anybody knows what i'm making wrong???
Thanks!
