About Using the managed-bean Element

Initializing Managed Bean Properties
why referenced bean can't instantiate? Please help.
<managed-bean>
<managed-bean-name>customers</managed-bean-name>
<managed-bean-class>test.Customers</managed-bean-class>
<managed-bean-scope> session</managed-bean-scope>
<managed-property>
<property-name>mailingAddress</property-name>
<value>addressBean</value>
</managed-property>
</managed-bean>

<managed-bean-name>addressBean</managed-bean-name>
<managed-bean-class>test..AddressBean</managed-bean-class>
<managed-bean-scope> none </managed-bean-scope>
</managed-bean>

Hi,
Maybe this helps:
When you create an object that points to other objects, do not try to point to an object with a shorter life span.
A scope of "none" means that the bean is created only when something else references it.
The life span is in this order: none, application, session, request .
Best regards,
Nick

Rss feed won't validate when I use the itunes:order element?

Hi
I'm trying to use the <itunes:order> element -
http://deimos.apple.com/rsrc/doc/iTunesUAdministrationGuide/AddingContent/chapte r12_section3.html
When I run my feed through the W3C rss validator it won't validate. It says - Undefined item element: itunes:order
I also get a recommendation which says - Use of unknown namespace: http://www.itunesu.com/feed
As far as I can tell I'm doing everything correctly. The iTunes and iTunesU namespaces are declared correctly in the root rss element and the itunes:order are where they should be within the <item></item> element.
What am I doing wrong? Any help would be much appreciated.
Here's my rss feed -

I have been in touch with someone at Apple and I was advised that I shouldn't worry about this.
It would seem that the feed validator doesn't recognise the iTunes U namespace and some of the iTunes and iTunes U specific feed elements. The use of an unknown namespace gives an adviosry note and <itunes:order> and <itunesu:category> elements will not validate at all. I suspect there may be other elements that I haven't used in our feeds.

How can we contrrol the focus of an form Object from the Managed bean??

I am getting the following script error...
Can't move the focus to the control because it is invisible or not enabled or of the type that does not accept the focus...
I have a button whose action is mapped to a function in the Managed bean.
In the managed bean
I am making the button Invisible along with some other components.
Can any one help me out....

@BalusC
You were proposing the following solution in other thread..
<html>
<head>
</head>
<body>
<f:verbatim>
<script>
setFocus('</f:verbatim><h:outputText value="#{myBean.focusId}" /><f:verbatim>');
</script>
</f:verbatim>
</body>
</html>
But it is giving the following error
javax.faces.FacesException: org.apache.jasper.JasperException: /EducationDetails.jsp(97,29) The element type "script" must be terminated by the matching end-tag "</script>".

How do I set the CoreTable sort column in the managed bean?

I have a CoreTable with two columns, first name and company, from the managed bean in a session scope, how do I set the company column to be the default/selected sort order?
Or is that done by binding the af:column to a CoreColumn object in the managed bean, which method would I use?
<af:column sortProperty="company" sortable="true">
<f:facet name="header">
<af:outputText value="#{common.labelCompany}"/>
</f:facet>
<af:outputText value="#{row.company}"/>
</af:column>
Thanks,
--Todd

Yes, I know, "sortable", see, I even used it in my example. I don't want to disable default sorting.
What I'm asking is how to have more than one sortProperty. When the user clicks the column heading, I want to sort by "myFirstProperty" AND "mySecondProperty". The sortProperty only seems to allow one sort property.
One possibility seems to be to programatically add items to the List of SortCriterion objects as in your example, but where would I put this code so that it is executed when the user clicks the column heading, but before the table is sorted.

How to use a managed bean in a bounded task flow without definig it in adfc-config

Dear all
I create a bounded task flow without page fragments (the pages are jspx), i created a jspx page with a button that its action has bounded to a managed bean function.
i defined the managed bean on the corresponding bounded task flow, but it does not work.
But there is no problem when i define the managed bean in adfc-config.xml.
can anybody help me with this problem.
is it possible to use jspx page with backing bean in bounded task flows, without defining the beans on adfc-config?
Thank you very much

Dear Timo
I use jDev 11.1.1.6 and the scope is Request.Although when i use task flow page fragment and create jsff pages, there is no problem.

Setting bind variable for a view object from the Managed Bean

Hi,
i am using JDeveloper 11g, i have to create LOV in the JSF. To show the LOV, it has to populate data using View object and its query parameter need to be sent from the Managed Bean.
For the View object i want to set the bind variable parameter from the managed bean value. bename is stored in a managed bean (session scope)
#{beantest.bename}
But it gives the following exception.
JBO-29000: Unexpected exception caught:
org.codehaus.groovy.control.MultipleCompilationErrorsException,msg=startup failed, Script1.groovy: 1: expecting '!',found '{'@ line1, column 2.

How to input the VO bind parameter with Managed bean variable?
Any Help
Regards
Raj
Edited by: user9928180 on Dec 17, 2008 9:51 AM

Hi,
a bind variable in a VO needs to be exposed as an executeWithParams operation in the pageDef file. Just add a new action binding to the pageDef file (context menu) and select the executeWithParams operation on teh VO. Then in the argument field, reference the managed bean property for the value

How to use the FormDownload UI element?

Hi,
I am a newbie in ABAP Webdynpro and I want to know how to use the FormDownload UI Element. Any hints plz? Thanks in advance.

Hi,
I used CONVERT_OTF FM to convert the otf data to pdf data. In my form user has the option to view the smartform (a button) or to directly download the pdf from smartform output without displaying the output. While the former has been taken care of by using InteractiveForm UI element and is displaying the smartform output fine, I am not being able to implement the second option. I have given a supply function to the pdfsource context node but am clueless about what to write to pass pdf data. In the sam WD component WDR_TEST_EVENTS, the FileDownload is used to save a text file with just one line. But how can I save a pdf file? I have assigned mime to application/pdf. How will I proceed now? Please suggest. Thanks in advance.

How to clear the Managed Bean Values prior to load a JSF page

Hello.
I have a jsf page that contains fields that need to be cleared BEFORE the page is loaded.
My managed bean where the fields are linked (I�m using the value attribute) is in the SESSION scope because I need to control they values across a popup window and if I use request scope, my vectors that load objects like dataTable are cleared when I post the form.
My question is :
How I CLEAR all the values in the managed bean BEFORE the page is loaded ???
In the WebForms (Microsoft .NET) I have an method on the codebehind called Page_Load where I put my initialization code for my page.
Thanks in advance.
Rog�rio

Rog�rio,
You can do this with a PhaseListener. Just regiser a new listener for the RESTORE_VIEW phase, and implement the beforePhase method; you can do this in the backing bean's constructor, or somewhere elase. This is pretty much the same as the Page_Load event handler in .NET.

The Managed Bean in the faces-config.xml File

I am still very new to JSF. I am confused about the managed bean.
For example, I have a button in my web page. A click on this button invokes an action; say, ListAction.java.
In this ListAction class, I instantiate a business delegate; say, ListPersonnel.java and call a method in this business delegate to return an ArrayList: personnel. Of course, this business delegate goes through facade, DAO, etc. to populate the ArrayList. This ArrayList is a collecation of a JavaBean called PersonnelBean that gets and sets a number of personnel information; such as ssn, name, etc.
Upon this ArrayList is successfully populated and received by the ListAction class, I am going to display a web page with a table. In JSF, it is <h:dataTable ...>.
My questions are regarding the managed bean in the faces-config.xml file.
1. Which one is my <managed-bean-class>? packageName.ListAction? or packageName.PersonnelBean? or something else?
2. What should be my <managed-bean-name>? I guess that I can give a name I like. Is it right? What about xyz?
3. Then, how do I specify the "value" attribute of my <h:dataTable ...> tag when I display a web page to show the data table? Is it correct to specify value="#{xyz.personnel}"? What is the correct specification if it is wrong?
4. I guess that I can give any name to the "var" attribute in the <h:dataTable ...> tag. Is it right?

1. Which one is my <managed-bean-class>?
packageName.ListAction? or
packageName.PersonnelBean? or something else?ListAction
2. What should be my <managed-bean-name>? I guess
that I can give a name I like. Is it right? What
about xyz?Anything you like. xyz is OK.
3. Then, how do I specify the "value" attribute of my
<h:dataTable ...> tag when I display a web page to
show the data table? Is it correct to specify
value="#{xyz.personnel}"? What is the correct
specification if it is wrong?xyz.personnel is OK assuming that ListAction class has a public
method getPersonnel() which returns the ArrayList of PersonnellBeans.
4. I guess that I can give any name to the "var"
attribute in the <h:dataTable ...> tag. Is it right?Yes, you can give any name you like.

How to pass js variable to be used in managed bean constractor?

Hi,
I got a list of items that i present in <h:selectOneMenu on my page (the first page the user sees)
the labels that are shown in the ><h:selectOneMenu are date + time , and the time itself is stored in the db in UTC without any + or - timezone offset (e.g UTC +2)
In order to show the correct time in the labels of the ><h:selectOneMenu I'm adding the needed offset of the user timezone
the problem is that the ><h:selectOneMenu is being populated from the managed bean before I'm passing the offset from the xhtml page itself using jQuery $.post(
like this
<h:head>
<script type="text/javascript">
          jQuery(document).ready(function($) {
               d = new Date();
               var tz = -1 * d.getTimezoneOffset()/60;
               $.post("/servlets/TimeZoneFromClientServlet",{timezone : tz});
       </script>
     </h:head>any ideas how can i pass the TimezoneOffset to the application before the managed bean is loaded?
Thanks ahead!
Daniel.

You know, any website I've encountered so far ASKS for your timezone. Why do you think that is?
In any case, if you really want to go ahead and do what you want, you need a single point of entry in your web application that sets the timezone in the session once so you can reuse it. It could be something as simple as doing it in a login page if you have one; just create a hidden input field that is prefilled with the timezone you find using Javascript; then simply submit it to the server and stick it in the session there. When the session times out the user would have to login again, which would give you the timezone value back.
another option: is the managed bean session scoped? If so you can simply fetch it in your servlet and update the appropriate property of the managed bean. This one makes me feel some shame for suggesting it though.

Which view object classes should be used by managed bean in ViewController?

I just like to find out which java implementation classes created for a view object should be referenced in a managed bean on the UI side.
For my view object InfoVO, I can create the following classes:
View Object class: InfoVOImpl
View Row class: InfoVORowImpl
View Row Client Interface: InfoVORow
View Row Client Class: InfoVORowClient
Currently, I use InfoVOImpl and InfoVORowImpl in my managed bean so that I can use the getter methods conveniently to access the attributes with proper data types.
I am not sure when I should use InfoVORow and InfoVORowClient instead of InfoVORowImpl.
What are the context and reasons for using InfoVORow or InfoVORowClient instead of InfoVORowImpl?

Hi,
all of these are wrong. If you want to access a method exposed on a ViewObjectImpl class, the you expose the method as a clientMethod (or clientInterface) in the Java options for the View Object (or Application Module if the method is on AMImpl). You should avoid using implementation classes directly in the managed bean. If you need to access a View Object, use its interface ViewObject. If you need anything more specific than that, expose a method on the client interface after which you can access it through the binding layer.

How to use the same bean from Jsp and Servlet

I want to use the same bean instance from both the servlet and jsp.
for eg. if a create a bean using the jsp:useBean in servlet and if a modify some values, that values should be reflected while i access the same bean from the servlet. But instead of that the servlet is creating a new instance of the bean.
is it possible?
Thanks in advance

Hi,
When you call jsp:useBean you inform a scope (session, request, page...)
This means the bean instance will be stored in that scope.
So, if the informed scope is session, then, in the servlet you could get the bean instance back from the session, this way:
HttpSession session = request.getSession();
Bean b = (Bean) session.getAttribute("bean_id");

Managed Bean "Name" Access with in the Managed Bean

Hi,
I have faces-config.xml in which I have registered a managed bean
and I have a base class for all the managed bean.
The JSP's invoke the action/method defined in the base bean and I want to remove the managed bean from session upon a particular event.
To remove the managed bean from session, as far as I know - we need to know the managed-bean-name in the faces config.
I wanted to know if there is any way to get the name of the managed bean in the faces-config.xml at run time?.
Thanks,

Thanks for your recommendations. The issue that I get stuck on is how to call this method that retrives employee data. When I had the code in the constructor, it executed when I accessed the view.jsp page. Then I populated the fields from the Employee class fields. But once I create non-constructor method, how do I invoke it from my JSF page.

How to pass a value from jspx page to the managed bean

hi,
i have created a jspx page and manages bean with page flow scope..
in my jspx page i am searching a employee record from the data base . and getting entire employee details including 'status' as a search result.
here i want to pass the value of 'status ' field to the managed bean variable called 'stval'.
can anybody suggest any solution?.......

As per the details provided in the post above, when the user clicks on the search in the af:query, the results are populated in the table. And you are interested in getting the value of particular column. This could be done by having the custom row selection listener to get the value of the current row (selected row in the table).
1) Have a custom selection listener:
<af:table value="#{bindings.EmpDeptVO.collectionModel}" var="row"
rows="#{bindings.EmpDeptVO.rangeSize}"
emptyText="#{bindings.EmpDeptVO.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.EmpDeptVO.rangeSize}"
rowBandingInterval="0"
rowSelection="single" id="t1"
partialTriggers=":::qryId1 ::ctb1 ::commandToolbarButton1"
columnStretching="column:c1"
styleClass="AFStretchWidth" columnSelection="multiple"
first="0" contentDelivery="immediate" autoHeightRows="10"
binding="#{pageFlowScope.ExampleBean.searchResultsTable}"
*selectionListener="#{pageFlowScope.ExampleBean.rowSelected}">*
2) In the method, set the current row programmatically:
ADFUtil.invokeEL("#{bindings.EmpDeptVO.collectionModel.makeCurrent}",
new Class[] { SelectionEvent.class },
new Object[] { selectionEvent });
3) Get the current row and get the required attribute values and set it in any of the variables in the managed bean:
Row selectedRow =
(Row)ADFUtil.evaluateEL("#{bindings.EmpDeptVOIterator.currentRow}");
String status = selectedRow.getAttribute("Status");
