BlazeDS and JSF

I have an existing JSF (really Oracle ADF) application that I'd like to connect to a Flex front-end rather than rewrite totally in Flex + JSPs for the back-end. BlazeDS will properly instantiate the managed beans through remote object requests, but the FacesContext references in my managed beans are null, as BlazeDS seems to have nothing to do with this context. Does anyone have experience connecting a Flex application to a JSF application properly, maybe through creating his/her own FacesContext factory?

<div class=Section1> color:#1F497D'>Hi,<o:p></o:p> color:#1F497D'><o:p> </o:p> color:#1F497D'>It’s pretty easy to integrate blazeds into an existing application. The war is just an example of how to configure and package blazeds. BlazeDS itself is just a servlet, with a collection of jars and some configuration files. You put the required jars into your WEB-INF/lib, the configuration files into WEB-INF/flex (If I remember correctly), and then map the blazeds message broker servlet in your web.xml file. You can open up the war file and see how it’s configured there and base your configuration on that. Depending on your needs and your servlet container you may have to add a jar file to your container’s lib or classpath.<o:p></o:p> color:#1F497D'><o:p> </o:p> color:#1F497D'>One of the benefits of blazeds is that if you’ve structured your application so that you’ve abstracted the view then you can just plop bds right in there and expose all your services through bds views.

How to integrate Single Sign-On and JSF?

Hi all,
We are going to develop a web application using Oracle technologies, including ADF and JSF.
But we´ll need to secure our website using Oracle Identity Manager (Single Sign-On). I am having difficulties to find any resource explaining how to do that.
Also, the IM (SSO) will run on a Oracle AS instance and our web app (ADF+JSF) will run on a separete OC4J instance, due to ADF version. Is this a problem?
Thanks

We too are in the process of implementing iStore with SSO features.
And if you believe me it seems to me as nightmare.
In our scenerio we are intgrating this SSO with Third party access control too (AD and Siteminder). I would request you to please respond me on the following mail id , so we can share our experince which will help us in our implementation
[email protected]
regards and thanks in advance

Facelets and jsf-extensions problem.

I'm fairly certain I've run into a problem between facelets and jsf-extensions. I'm working with JSF 1.2 RI, Woodstock, Facelets 1.1.13, on Tomcat 6.
When trying to get Woodstock autoValidation to work I get a javascript error the "I has no properties". The error occurs in the com_sun_faces_ajax.js file in the jsf-extensions-dynamic-faces-0.1.jar (I've used both the RC4 and a build today ,10/18/07 from source with the same results). Here is the code snippet where it happens (with my comment).
var I = G.getElementsByTagName("components")[0];
var C = I.getElementsByTagName("render");
for(var F = 0; F < C.length; F++) {
In the second line there it looks like the variable I is null, but based on the post response below I don't know why.
The response from the post looks like this:
<partial-response><components><render id="PayableForm:vendorGci"><markup><![CDATA[{"valid":true,"id":"PayableForm:vendorGci"}]]></markup></render></components>
However the server side code (validation method) never gets executed. I'm willing to do some digging and debug work, but I'd need to be pointed in the right direction.
The following is more potentially useful code snippets.
Here is the textField code:
<w:form id="PayableForm">
<w:textField style="display:none;" />
<w:message for="vendorGci" />
<w:label id="vendorGciLabel" for="vendorGci" text="Vendor: " />
<w:textField id="vendorGci" autoValidate="true"
text="${vendorBean.searchGci}" maxlength="8" required="true"
validatorExpression="#{ vendorBean.validateVendor}" />
Here is the javascript in the page (the init function is called from the body: onLoad="setTimeout('init();', 0);" , this does happen):
<w:script type="text/javascript">
function VendorListener(){
function VendorNotify(props){
alert("VendorNotify called!"); <--------------- I never see this alert message
if ( props.id != "PayableForm:vendorGci") { return; }
var field = document.getElementById("PayableForm:vendorGciLabel");
field.setProps({
valid: props.valid
VendorListener.prototype.notify = VendorNotify;
function initAccountRows(){
var table = document.getElementById("PayableForm:vendorAccountTable");
table.initAllRows();
function init(){
initAccountRows();
var listener = new VendorListener();
dojo.subscribe(
webui.suntheme.widget.textField.event.validation.endTopic ,
listener, listener.notify);
Here is the validator method. It currently doesn't do anything, just trying to get something to work. I never see the output, and I never hit the breakpoint in the method.
public void validateVendor(FacesContext context, UIComponent comp, Object value){
System.out.println("**********************************");
System.out.println("validateVendor called");
System.out.println(value);
System.out.println("**********************************");
}

Actually I don't need a global variable. I need to refer in my included template the actual backing bean used in the current page. As all my backing bean extends a abstract class I could bind my component to a property of the current backing bean, no matters which one. Just like a polymorphic call but without the parameter. Let's imagine I could get this object of the facesContext object I would be able to do:
<rich:datascroller renderIfSinglePage="false" align="right" for="listagem" maxPages="12" fastStep="10"
pageIndexVar="pageIndex" pagesVar="pages" stepControls="show" fastControls="hide" boundaryControls="show"
inactiveStyleClass="paginacaoInativa" selectedStyleClass="paginacaoSelecionada"
styleClass="paginacao" tableStyleClass="paginacaoTabela"
binding="#{facesContext.currentBackingbean.formDataScroller}" id="paginacao">
Instead of pass the backing bean to the ui:param of this template... Dou you get the point?

Hi!
I am using Flash Builder 4.6, BlazeDS, and Hibernate. How to store a webcam snapshot into the MySql Database. I stored Form Items by using RemoteObject into the database. But I failed to store webcam snapshot. I captured that image on Panel component.I converted that image to ByteArray. Now I want to save that image into the database. Please help me in this regard.
thanks in advance.

What's the difference between jsp and jsf?

who can tell me what's the difference between jsp and jsf?
I'm puzzled when I found some of the technology in jsp is so similar to the ones in jsp( javaserver page)

Hi,
Find the difference between JSP and JSF
1. A developer has more control with JSP, but (should) get easier development with JSF
2. Event handling is done differently in JSP (HTTP) and JSF (Java)
3. The UI is designed differently (or should be at least) with JSP (markup) and JSF (components).
4. The end product should also be defined differently - JSP page versus a JSF application.
Is this the only thing that is need to make a decision for either or? Probably not. There are other pieces that need to be taken in account when deciding which technology to use - tools support, enough components, type of application etc.... At this point there are not enough JSF components (although there are some interesting projects underway - Ajaxfaces, Myfaces, ADF Faces, and WebChart 3d) and enterprise tools support is still limited to a few tools vendor. Looking at our ADF Faces components they are currently available as early access (not production) and demands for these components are stacking up, literally, outside my office doorstep. Although I would love to make them production - now! - it is not a viable solution since we are still checking features and fixing critical bugs.
All this combined - not enough enterprise level components in production, lacking tools support etc... - leave customers in a vacuum where the decision is either to continue with JSP, since it is mature and has a wide developer base, or move forward with JSF not sure if the support, or the developers will be there. This is particularly sensitive to customers that need to get started now and be production by summer.
If you are in this vacuum here are some key points promoting JSF:
1. Fundamental unit is the Component
2. Built in event and state management
3. Component sets can be provided by any vendor
4. Closer to ASP.Net or Swing development
5. Choice of UI technology
6. Scale up (rich clients)
7. Scale down (mobile devices)
8. Built into J2EE containers in J2EE 5.0 (tentative)

Getting started with Flex Builder, BlazeDS and Eclipse

Hi,
I'm a java developer looking at RIA for the first time. I'm really excited about BlazeDS and object remoting, but I can't get a working dev environment together. I'm assuming I should use Flex Builder for the client code, Eclipse Europa for the java webapp code, and deploy from both IDEs into the BlazeDS-equipped turnkey-Tomcat. I haven't found a tutorial explaining how to deploy a new webapp with this setup.
The turnkey-Tomcat sample app works fine. Trouble starts when I try to create a new project in Flex Builder. I don't understand the 'debug' deployment that Flex Builder does. Why are there 2 versions of my app, the regular and the debug versions? What is exactly the project structure that I'm supposed to have in Tomcat?
The specific error I encounter when trying to deploy a new Flex project is this:
[MessagingError message='Destination 'productService' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']
I do have a default channel configured for my environment in services-config:
And I do have a valid destination configured in remoting-config (I'm mostly interested in object remoting):
test.ProductService
Here's the client code:
What am I doing wrong? Where can I get help on these specific topics? Also, does anyone have an Ant build file that would automate this sort of deployment?
Thanks!

Hi Peter, I don't have problems passing JavaBeans to Flex. For collections, I used DataGrid, it displayed my collection seamlessly, except I don't get column headers, just a column index number. For receiving a single JavaBean, I had a little more trouble, until I tried to display it with a DataGrid: it displayed a single row that represented my data, with each java property name used as a column header, and object attributes were displayed as 'object'. These 2 experiences led me to these conclusions: - for the collection, Flex converted each element into an ordered list of attributes - for the single bean, Flex converted it into a hierarchy of Maps of attributes I didn't create a Flex value object. Flex is doing it automatically,very much like in JavaScript/JSON: dynamic objects. Here's the remote object markup:  <mx:RemoteObject id="myRemoteObject" destination="productService" fault="Alert.show(event.fault.faultString, 'Error');"> <mx:method name="getProductsCount" result="setProductsCount(event)"> <mx:arguments> <arg1>{productSC}</arg1> </mx:arguments> </mx:method> <mx:method name="getProducts">  <mx:arguments> <arg1>{productSC}</arg1>  <arg2>{pager.pageSize}</arg2> <arg3>{pager.currentPage}</arg3> </mx:arguments> </mx:method> <mx:method name="getProduct" result="goToView()">  <mx:arguments> <arg1>{selectedRecordId}</arg1> </mx:arguments> </mx:method> </mx:RemoteObject> And here's the dataGrid that displays the bean collection: <mx:DataGrid id="myDataGrid" dataProvider="{myRemoteObject.getProducts.lastResult}" change="selectRecord();" width="100%" height="100%" > </mx:DataGrid> Let me know how it goes, I'd be glad to assist if I can.

Struts and JSF Integration in OPDk-java based portlet

Hi,
thanks in advance for your help.
I'm developing a PDK java based portlet. For some reasons I cannot use the JSF bridge but I would like to integrate Struts and Jsf in my portlet, using Struts to manage actions and navigation and JSF (with ADF Faces components) for the view. I'm using the Strus-Faces library.
When I try to submit my portlet form, I receive the error "request URL not found on this server". I'm posting some exstracts of my code.
It's made of three pages: the main one "Integration1ShowPage", "error" and "result". The MainAction.java displays my mainPage, where there's a form. To keep it easy, when the user submits this form, the ActionName returns "success" and the "result" page should be displayed.
The MainAction works properly: the portlet is displayed but when I tried to submit the form I receive
The requested URL /provaDeploy/htdocs/integration1/integration1ShowPage.do was not found on this server.Could you please suggest me something?
Many many thanks,
B.
<struts-config>

Hi,
have a look at this whitepaper for how to use JavaScript in ADF.
http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf
This link here (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html --> see sample 71) shows an integration sample between a Java Applet and ADF. Its a similar use case to yours

Can Struts and JSF coexist?

I have a Struts based application and now I want to build an additional module on top of that using pure JSF. My question is, can Struts and JSF co-exist in the same application? If yes, what are the cons of that approach? What are the places I need to tweak in the configuration files so that they work together?
thanks,

Hi,
Yes they can coexist. Actually that's the approach recommended by Craig McClanahan. I have developed a full enterprise application (80% completed) which uses JSF in front and Struts in the back using Struts-Faces integration library (developed by Apache).
So far I haven't faced any major issues with this approach. However, I haven't try using Struts validator on JSF objects.
Read the article below on how to integrate JSF w/ Struts.

JSF datatable - any difference with JSF 1.1 and JSF 1.2

Hi All,
In my project there are lot of Datatables, which retrieve data from the database and display it to the user. For each datatable, the columns are not fixed. I want to create some kind of component that can be reusable.
It is basically a JSF portlet. Now i have to use RAD 6. RAD 6 supports only JSF1.1. I have to migrate this to RAD7 in the near future. Are there any differences between the Datatable in JSF 1.1 and JSF 1.2?
I had this approach in mind.
a) Create the datatable programmatically and put the contents to panelgrid. This way the jsp code will be minimized. Is it a good option.? Are the APIs same in both the versions?
b) Is it possible to create a custom datatable which can take some key as input. Then based on the key the datatable can be populated with as many columns as desired.
Please let me know if there are any other good options.
~Anitha.

Hi guys,
my code goes like this..
for (int j = 0; j < size; j++) {
 UIColumn column = new UIColumn();
 dataTable.getChildren().add(column);
 HtmlOutputText header = new HtmlOutputText();
 header.setValue(periodHeader[j]);
 column.setHeader(header);
 HtmlOutputText output = new HtmlOutputText();
 output.setValue(new Double(periodLiability[j]));
 ValueBinding vb1 = FacesContext.getCurrentInstance()
 .getApplication().createValueBinding(
 ("#{liability.periodLiability["+j+"]}"));
 output.setValueBinding("value", vb1);
 column.getChildren().add(output);
this code gives me the number of headers i need. But, it doesnt render the columns. I have an array of Double (periodLiability) which stores few values of Double type. I want to show thesee values inthe dataTable Column.
Please help me..

Some advice please, BlazeDS and some ideas

HEllo all,
I am planning on building an app out, that has two versions, viewer and admin. The admin will be allowed to upload images, and then display an image of choice on the viewers page, and be able to change these images at will, with the viewers page automatically updating.
Kind of like a daynamic image sharing thing.
Now i have been doing some research in how to do this, and stumbled along BlazeDS, and am wondering if something like this is possible with Blaze, i know it can support sending and recieving text based messages really well, but dose it suppose images in the same way ?
Any advice would be great !

hi,
You would still use the messageing system of blaze to tell a user an image has been modified then tehy would download it again, much the same way we did with the video app you would have a key word in the message that triggers a dowload event.
For instance a user uploads an image when the event complete is fired it feeds a message to the server "imageUL:image001.jpg" the serevr then posts a message to all clients "imageED:USR:image001.jpg"
when you get the message it fires the download event because ther first 7 characters ="imageED, the character between the colons is the user id so if you where the one that updated the image you would not proceed to download the image.

BlazeDS and JBoss

Hi All,
I have this BlazeDS problem I need help with....
I need to get Flex application to "talk to" java on the back-end.
For that to work, as you know, I need BlazeDS and, among many, JBoss application server.
I was wondering if someone knows how to integrate BlazeDS with JBoss?
I got stuck with this part....
I've seen some tutorials on the Internet suggesting to just put blazeds.war file into JBoss' deploy directory.
(server/default/deploy/) I think was the path....
I tried that and in fact this worked. I was able to run sample application too.... Strange.
The problem is that I need to control and map my java class to the flex class, which involves editing some config file.
If I'm not mistaken this file is in the blazeds.war file so I can't really edit it. And what if I have to make a change to it?
I can't just figure this whole thing out and run Flex project in Eclipse that "talks to" a java class.
Please note that I have to use JBoss and NOT Tomcat. If I can just correctly integrate BlazeDS with JBoss I'll be half way there already....
Thanks for any suggestions.
Gregg

Hi,
You have 2 options. Probably the preferred method during development is to use an expanded war. Create a subdirectory in the deploy directory named blazeds.war and expand the blazeds war file into it.
If you are ready to deploy the webapp, you can jar the directory back up and deploy it as a war. But as you have seen you cannot make updates to config files or classes on the war file itself.
