Refencing ADF Bindings with TagLibs

If I reference my binding with <c:out value="${bindings.pageNumber}" />
The page number is printed out on the page.
Now if I use the page number for my pagination links tag library like this:
<page:GeneratePageLinks currentPage="${bindings.pageNumber}" />
The actual String "${bindings.pageNumber}" is passed in instead of the actual page number.
Anyone have an idea of how to get this to work?

I have not used the Pagination Links Tag Library but I am familiar with using custom tags. The <rtexprvalue> tag of the TLD file of a custom tag library specifies whether the attribute's value is determined from a runtime expression. If it is set to true, then you can use EL to set the value of the attribute. If it is set to false, then the attribute value cannot be set with EL and must be a string. So if you have access to source code and can change the TLD file, just set the <rtexprvalue> tag of the currentPage attribute to true. Otherwise, you are out of luck trying to use EL with that attribute.

ADF Bindings with LOV

Hi,
I have a list of values field on my page and when i select a value from this, it defaults the values to the other fields too. However these(defaulted fields) are not getting saved eventhough i set the property for these fields as Autosubmit=true.Any ideas?
Thanks,
Lakshmi.

Hi Shay,
I set the partial trigger to the parent item. but still the same. I was able to default the child items when a parent item is selected. However, the data structure i have is an XML data and not from a VO.
1. My adf table is based on XML payload.
2. Created a VO with 3 columns
3. Created 3 new columns in the adf table.One of them is Input List of values
4. Drag and dropped the 3 feilds from VO data control onto these fields
when i run this page, i can select the values from the LOV and it gets defaulted to the remaining 2 fields.
Now i want to populate the 3rd field value into one of the columns(which is not in the VO) in the adf table.
Thanks,
Lakshmi.

ADF Paging with EJB3.0

Hello,
I'm using ADF faces and ADF bindings with EJB3.0
I have af:table with paging, but that is only visual it still gets a list with al my objects.
Is it possible to have real paging that only gets the displayed data from the database.
Regards,
Tim

Hello,
I already have the method on the EJB, you pass the parameters, the number of the first record and the number of records you want.
The problem I'm having is that I don't know how to make adf call it.
I've used this with myfaces
http://wiki.apache.org/myfaces/WorkingWithLargeTables
But if I use something like that I can't use the bindings.
Am I right in presuming that the adf table only uses get(int pos) and size() to get the data from the collection. If so it was thinking about creating a PagedList based on the myfaces DataModel example. I don't really like that solution, but I don't know a better one.

Tim

ADF bindings are not working with inheritance heirarchy.

ADF bindings are not working with inheritance heirarchy. I am using embedded OC4J in JDeveloper 10.1.3.2.
For the data model I have the following objects\attributes.
1) User (abstract EJB 3.0 POJO)
- Id
- userId
- userName
2) Employee -> extends User (EJB 3.0 POJO)
- enabled
- password
3) Manager -> extends Employee (EJB 3.0 POJO)
- numOfEmployees
4) UserSessionBean (Stateless Session Bean)
- public User findUserByUserId(String userId)
- public List<User> queryUserFindAll()
- Object mergeEntity(Object entity)
I created 2 JSF pages using ADF.
1) ListUsers.jspx - Lists all the users of type Employee and Manager in a table. You can select an user and chose to modify the user details using a modify button.
2) ModifyUser.jspx - Modify the selected user and persist the modified user details.
I implemented ListUsers.jspx by dragging and dropping queryUserFindAll() method from the ADF datacontrol on to the JSF page and selected ADF Table format with selection enabled.
Similarly for the ModifyUser.jspx page I dragged and dropped the User object returned by findUserByUserId(String userId) and selected ADF Form format. I selected OutputText field types for userId and userName.
I then created a navigation case from ListUsers.jspx to ModifyUser.jspx and pass the selected user.
Now when I try to run the web application, ListUsers.jspx correctly displays all the users. Then I select a user of type Employee and click on the modify button. This brings up the ModifyUser.jspx page. However, the UserId text field displays the value for "Id" field rather than "userId".
Question that I have is:
- Why is ADF framework not able to retrieve the appropriate user attribute value for a Employee based on the binding information in case of inheritance ?
Thanks,
Piyush

Hi,
tried with JDeveloper 10.1.3.3 and this works for me. Try JDeveloper 10.1.3.3 - if it doesn't work, have a closer look at your sessionFacade

ADF Bindings CRUD with either JDBC or Hibernate

Does anyone know of an example CRUD application that uses ADF Bindings and either Hibernate or JDBC.
The site...
http://technology.amis.nl/blog/index.php?p=765
uses ADF Bindings and Hibernate, but does not update a database.
I have attempted to do this myself, but when my add/edit page loads, all of my af:inputtext controls display labels instead of input boxes.
There are several ADF Biding examples for both Toplink and ADF BC, but if anyone can point me in the direction of examples for JDBC and/or Hibernate, I would appreciate it.

I have created the target datacontrol for ADF Binding.
In my DataContorls.dcx file, my datacontrol (a JavaBeanDataControl, not an AdapterDataControl) has its SupportsUpdates attribute = "false".
When I create a form, the #{bindings.<my_property>.updateable} expression returns false, making it so my af:inputText controls cannot take input data. If I manually set SupportUpdates="true", my #{bindings.<my_property>.updateable} expression still returns false.
If anyone knows how to set it so I can make it so I can update my java objects, I think I will be set.
Any help would be appreciated.

ADF Faces with ADF BC

Hi everyone,
I'm trying to map a <af:table> to an ADF Business Component. I can retrieve the records and I can also navigate doing Next and Previous, but I cannot do a Delete of a record. Do you know if there's any kind of "work arround" to use ADF Faces with ADF BC to do a delete or update, etc.?
Here is the code, you can notice the: <af:tableSelectOne> tag to put the radio buttons colums to select which one to delete, and you can also notice the action="#{row.markForDeletion}" for the commandbutton to perform the delete.
Jonas Jacobi wrote in his web blog on August 16 that he was going to post some samples for this "work arround" but I think he never posted them.
Here is the code:
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://xmlns.oracle.com/adf/faces/EA12/html" prefix="afh"%><%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>

Thanks,
Pablo (sorry for the long post)

Thank you Gabrielle. At least now I have an excuse to tell my boss why I can't get it to work.
Any idea when it may be available? Would it be a better idea to implement the table in plain vanilla JSF, and when ADF Faces is ready for ADF BC then do the migration?
Are there any workarround to this problem?
Thank you for your time,
Pablo

ADF Bindings Servlet/Filter not invoking Faces Servlet

I'm getting ADF Faces and Facelets working properly with pages written in jspx format, but the Faces Servlet being mapped to jsf format.
The problem I'm getting is while displaying ADF Tables with data retrieved from the database using Toplink and bindings provided by ADF Databindings.
The following is the Web.xml mappings for Faces Servlet and ADF bindings filter:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>resources</servlet-name>
<url-pattern>/adf/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<filter>
<filter-name>adfBindings</filter-name>
<filter-class>oracle.adf.model.servlet.ADFBindingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jspx</url-pattern>
</filter-mapping>
I'm getting the ADF tables displayed using ADF Bindings, if the faces servlet is mapped for jspx format;but, at the cost of losing Facelets...Facelets is not working with Faces Servlet mapped to jspx format(though written in jspx format, the faces servlet mappping has to be made for jsf format.On the other hand, if I use faces servlet mapping for jsf pages I'm getting Facelets working but ADF Databindings are not working ,(I guess) and hence ADF Faces Tables are not being displayed(I'm getting Access Denied message).
I even tried to change the ADF binding filter mappings
---- from ---- jsp &jspx---- to ----- jsp and jsf ----
But I got the same Access denied message.
I read a similar post on this forum by Mr.Ashish Kumar who said he is using java script and automatic form submission, to refresh the page and that gave him the table working.
as quoted in the post:
af:table displays Access Denied
Why should the page be refreshed at all. I Guess , the Faces Servlet is not being invoked by the ADF Bindings Filter/Servlet, and for this , I suppose , Mr.Ashish is using java script to provide the action required.
And one more thing which that Automatic Refreshing of page using JavaScript cannot do.
Suppose,
I need customised display, rather than just a Table or Form,like:
public String getEmp() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("findAllEmp");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
List<Emp> res=(List<Emp>)result;
for(int i=0;i<res.size();i++)
Emp myrec=res.get(i);
System.out.println("Employee ["+myrec.getEname()+"], Salary ["+myrec.getSal()+"]");
return "";
where I do some customisation in the backing bean.
and I call that method binded to a button as below:
<af:commandButton
text="findAllEmp"
disabled="#{!bindings.findAllEmp.enabled}"
binding="#{backing_Success.commandButton1}"
id="commandButton1"
action="#{backing_Success.getEmp}"/>
What I'm getting is a disabled button.
Why doesn't ADF bindings servlet invoke the faces Servlet?
Can't we make ADF Bindings Servlet invoke Faces Servlet by configuring in the web.xml?
Can't we get ADF Bindings filter mapped to work with jsf pages?
Won't ADF Bindings work with jsf pages, will they work only with jspx pages?
ADF Team,
Please Help me.
Thanking you,
Samba

Hi! Frank,
Thankyou for your Reply.
Yes, Mr.Adam Winer has contributed that library, I guess.
But I already have that adf-facelets.jar in my lib folder ; and with out that the Facelets won't work with ADF faces , in the first place.
I'm getting Facelets working excellently with ADF Faces but I'm not getting ADF Bindings working with Faceletpages.
The thing is even in another application which does not have facelets in it, if we use mapping for jsf pages, ADF Bindings are not working.
I think the ADF bindings filter is configured some where to work with jspx pages only.Could you tell me where to change that entry to make ADF Bindings work with jsf extension?
Thanking you,
Samba.

DWR + ADF Bindings get Binding Container at the Filter level

Hi I'm still pressing on to use DWR with the ADF Bindings.
To do this, The managed bean method called from javascript needs access to the BindingContainer object or the "#{bindings}" property which is not available out of the box when setting up DWR according to their documentation. So I need to maybe an additional filter or extend the DwrFilter to do this.
Any ideas how to get or create the bindingContainer object or the "bindings" during the execution of the FacesFilter stage?

Why is ADF Bindings node not displayed in Expression Builder window?

Hello,
I'm using Oracle JDeveloper Studio Edition Version 11.1.1.1.0, and I've created a Fusion Web Application and I've configured ADF Authentication and Security for my web project, using the provided wizard.
On a certain page, I've placed a Go Link component, and I'm trying to edit the Text and Destination Property using EL Expressions. When I open the Expression Builder window all I can see are the following nodes: ADF Controller Objects, ADF Managed Beans, JSF Managed Beans and JSP Objects, but no ADF Bindings. I need to access the securityContext properties, and from what I've read in B31974-03, I need ADF Bindings.
Also, I've tryied using the search field from the Expression Builder windows, without any luck.
This is probably a newbie problem, but I really can't figure it out. Please help.
Bogdan.

Hi,
maybe your problem is that you don't have created pageDef related with your page. Try right click on your page and Go To Page Definition. It will create the related pageDef if it does not exist.
Hope this helps

Tomahawk and ADF bindings conflict

Hi, I use Tomahawk components <t:dataTable> and <t:dataScroller> to handle table with large number of rows (I learned from http://wiki.apache.org/myfaces/WorkingWithLargeTables)
The problem is that after I added ADF bindings to call EJB session bean methods, six navigation image buttons (first, last, previous, next, ff, fr) have been disabled. It seems that ADF does something to disable JavaScript code which activates these buttons (I noticed some changes have been made in faces-config.xml and web.xml). It took me 6 hours to find bugs but I've reached nowhere. :) Pls help me.
Thanks a lot!

Hi Frank, I have a method:
public List <SimpleCar> searchCar(int start, int rows);
in a session facade bean called CarFacadeBean.
And the following is the Page Definition.
<?xml version="1.0" encoding="UTF-8" ?>
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel"
version="10.1.3.40.66" id="carsDataModelPageDef" Package="view.pageDefs">
<parameters/>
<executables>
<variableIterator id="variables"/>
</executables>
<bindings>
<methodAction id="searchCar" InstanceName="CarFacadeLocal.dataProvider"
DataControl="CarFacadeLocal" MethodName="searchCar"
RequiresUpdateModel="true" Action="999"
IsViewObjectMethod="false"
ReturnName="CarFacadeLocal.methodResults.CarFacadeLocal_dataProvider_searchCar_result">
<NamedData NDName="start" NDType="int" NDValue="15"/>
<NamedData NDName="rows" NDType="int" NDValue="15"/>
</methodAction>
</bindings>
</pageDefinition>
Then in backed beans, I put:
BindingContainer bindings = this.getBindings();
OperationBinding operationBinding = (OperationBinding) bindings.getOperationBinding("searchCar");
List <SimpleCar> cars = (List<SimpleCar>) operationBinding.execute();
to get the result set from EJB method (searchCar(start, rows)).
These are all basic things, I believe. The problem occurs only after I dragged the method searchCar from Data Control Pallete to the page (there is only one page in this testing view). May I upload the code to somewhere so that you can take a further look?
Regards,
Harry.

ADF Faces with NetBeans

Hi,
This is Sandip Kulkarni.
I want to know that, how can we use or integrate ADF Faces with NetBeans 6.1 or NetBeans 6.5?
Please assist me with the solution as early as possible........
Thanking you

Sandip,
In all honesty, if you want to do ADF development - JDeveloper is the only game in town... yes, I know you can make it work, but it's not going to be productive. If you are talking about ADF Faces only, you may be able to configure the taglibs + etc in Netbeans, but not sure it's going to be fun. If you want to bring ADF Business Components into the mix, it's going to be unworkable.
One thing you could look at doing is to use something like maven - and then use Maven to generate the Netbeans artifacts.
Caveat: I've not done this before and cannot comment on how workable it will be.
Why don't you want to use JDeveloper?

Workaround for missing ADF Faces Cache taglib

I've downloaded Steve's migrated version of SRdemo (http://otn.oracle.com/products/jdev/tips/muench/1013srdemo/SRDemoSampleADFBC_migrated_to_11g_otn3.zip) and am trying to run it on JDev 11g TP3. However it couldn't find the ADF Faces Cache taglib in the afc.jar file that is deployed within the UserInterface project as it looks for a D:\temp... path.
A workaround for this is to:
* go to UserInterface "Project Properties...", choose JSP Tag Libraries: "ADF Faces Cache 1.0" will be shown in red as it references jar:file:/D:/temp/SRDemoSampleADFBC/UserInterface/public_html/WEB-INF/lib/afc.jar!/META-INF/afc.tld
* delete the red "ADF Faces Cache 1.0"
* click "Add", "User" folder at top, then click "New" button.
* navigate to the directory where your SRDemo project is stored and then UserInterface/public_html/WEB-INF/lib/afc.jar - then click OK.
* it calls this "ADF Faces Cache [1] 1.1" - select this and click OK, then save the project properties.
You should now see ADF Faces Cache [1] 1.1 in the list - I'm assuming this is a new version of afc.jar not yet bundled with JDev 11g.
HTH. Any comments or alternative suggestions welcome!

2. Answer its question Itself. Yes, change the filling items in SelectOneChoice through ForEach on preparing the reference book in BackBean and bind it with attribute "value" of f:selectItems speedup rendering about 6 times!

ADF Taskflows with EJB and pageflow scope

Hi,
I am trying to create a simple registration page which is very simillar to FOD customer registration using EJBs instead of ADF BC.
I can achieve the registration in one page but I wanted to try this using a wizard based process using ADF taskflows.
I created a bounded taskflow with 3 pages. page1 is employee details, page2 is job details, page 3 is the summary page. I have JPA entities for Employee and Jobs and an EJB3 session Facade. I have used the Employees default constructor to create the UI bindings from the constructor section of the data controls. This creates an EmployeesIterator which I use it for bindings on all the three pages.
My question is can I use this Iterator binding in pageflow scope? If yes How do I do this?
The other way is to use a managed bean in pageflow scope and have UI bindings to the variables in managed bean. This option will work but I will not be utilising any of the features of ADF bindings.
Can anyone please suggest which is the better option.
Thanks
Venkatesh

Hi,
pageDef files can be shared, but their instances aren't. The caching is on the data control side, which means that instead of using a constructor you would break up the input form into method calls like
createPerson(String, fn, String ln, String address)
createInterest(String hobby1, String hobby2);
dagging and dropping the method calls should the reate an input form. Submitting the forms allows you to build a new person object on the session facade which at the end is committed. This way the ADF binding works across pages, operating on a single new object
Frank
Ps.: Note that I did not run this example for a test

Packaging ADF application with Libraries

Hi Experts,
I was exploring on packaging/ bundling an ADF application with all required libraries, so that this application can be deployed on any J2EE server.
I have gone through another thread on similar topic - Error while deploying ADF application to a standalone weblogic server
Above thread says that installation of run-time libraries are must. But I want to dig little deeper into the reasoning.
What are libraries that can't be added into Application WAR file? (Normally J2EE developed application can be bundled and deployed on any of these servers (Weblogic/ tomcat/websphere)).
Is it possible to bundle ADF application with all libraries and then deploy it to Websphere server directly (without installing 3rd party libraries)?
Any help on this is appreciated.
Thanks,
Randhir

Timo / Frank / Shay,
Thanks for your help.
Websphere server is being used by other applications. So the intention of bundling libs was to check ADF application funcationality on Websphere server without installing 3rd party ADF libraries (installation may conflict other libraries and some application can stop working).
I gave a try on bundling all libraries with ADF application, but still I can see some error messages about missing libraries.
What is your suggestion on installing 3rd party libs on Websphere server? Will this impact any deployed application?
Thanks,
Randhir

ADF Table with CheckBox - Select/deselect issue

I have seen couple of threads and blogs for ADF table with check box . but none of them exactly matching with my requirement . My Database table does not have any field for check box .
Here is my DB Table
tableA_
A_Id
A_Name
tableB*
B_Id
Requirements :*
1. Display the above tables data with Checkbox . ( if A_Id = B_Id then the checkbox will be checked , else unchecked ) .
2. Select / deselect the check box and save the data . Saving the data , will update only tableB . i,e when a new check box is selected then A_Id value will be inserted to tableB . Similarly , deselecting a checked in data will remove the entry from tableB.
Development :
1. Created a VO where tableB has marked as updateable .
2. Created a transient Boolean variable for checkBox . and modified the getter method of checkbox for returning true/false based on the below condition in the ViewRowImpl Class .
if ( A_Id = B_Id )
return true;
else false ;
3. I have not modified the setter method .
Using the above concept i can view the data with selected checkbox . but the problem is to save the data . because , when I select a checkbox the above coding in the getter method will return false .
Therefore , though i am selecting the checkbox but value of the checkbox has been set as false .
While saving the Data , I am iterating through the VOIterator and observed that a newly selected checkbox value is false . and realized its because of the getter method condition .
Can you please suggest how can I overcome this issue or shall I need to take any other approach ?
Jdev version 11.1.1.5

You need to go through the ADF page life cycle concepts. In simple words the boolean value in the model is not set while in valueChangeListener. Try adding valueChangeEvent.getComponent().processUpdates(FacesContext.getCurrentInstance()); on top in your listener method and see the effect.
