It is a common scenario that you use the same ADF app for different versions of the BPM flow. In those cases you would like to control the visibility of the new features of the ADF app that supports the BPM flow changes .. Here is the way to read this info from ADF Add below to you page definitions.. <accessorIterator id="scaIterator" MasterBinding="taskIterator" Binds="sca" RangeSize="25" DataControl="Details" BeanClass="Details.scaType"/> <attributeValues IterBinding="scaIterator" id="compositeVersion"> <AttrNames> <Item Value="compositeVersion"/> </AttrNames> </attributeValues>                And then control your features as below, assuming the new button is visible at 1.10 rendered="#{bindings.compositeVersion.inputValue  >= 1.10 }”

It is very common that once you release your application you may need to execute some SQL queries through your application for trouble shooting purposes etc. I wanted to try how possible to implement  this in ADF and here is what I found in a very primitive way. I have a text area for the user to enter the SQL query and when the execute button is clicked the results will be displayed in the table below. In able to achieve this I am creating a View Object from a SQL statement in my AM. AM code ... @Override protected void prepareSession(Session session) { super.prepareSession(session); if (findViewObject("SQLVo") == null) { createViewObjectFromQueryStmt("SQLVo", " select 1 from dual "); } } public void executeSQL(String pSQLQuery){ ViewObjectImpl vo = null; if (findViewOb...

Say that you have a table created with this script, create table users(user_name varchar2(20) primary key, name varchar2(100),active_yn varchar2(1) default 'Y') And you want to set the active_yn to N when a delete occurs instead of doing a hard delete. I found this solution working, I am still not sure whether it is the best way or not.. I created my entity by using the wizard . Then edit the entity and on the Java tab select the below check boxes to generate the required Java classes. 1-Generate entity object class 2-Remove method 3-Data manipulation methods Then in the generated Java file change the remove and doDml methods as below /**Add entity remove logic in this method. */ public void remove() { setActiveYn("N"); super.remove(); } /**Custom DML update/insert/delete logic here. */ protected void doDML(int operation, TransactionEvent e) { if (operation != DML_DELETE) super.doDML(operation, e); ...

Yesterday I was experiencing some login form, in which I am calling a backing bean when the login button is pressed. In the backing bean depending on the return of the operation call I want to redirect the navigation to the corresponding page. After doing some research in the forums I found the below solution. We use NavigationHandler class to redirect the flow of the application. public String doLogin() { BindingContainer bindings = getBindings(); OperationBinding operationBinding = bindings.getOperationBinding("login"); Object result = operationBinding.execute(); FacesContext context = FacesContext.getCurrentInstance(); NavigationHandler nh = context.getApplication().getNavigationHandler(); if (((String)result).equals("SUCCESS")) nh.handleNavigation(context, null, "SUCCESS"); else nh.handleNavigation(context, null, "ERROR"); return null; }

Some ADF experts created a mailing list on Google to discuss the best practices with ADF. Here is the link to be part of that group http://groups.google.com/group/adf-methodology?hl=en

I will go over how to call a PL/SQL function from Jdeveloper 11G Tp4 First create a function that you will use , for this I used JDeveloper's database editor Then create an ADF project and an Application Modulu within the new project. Follow the wizard until the Java screen, there we need to check the first check box to generate the Java class file for the application module. Once you are done with the wizard you will see that a Java file was created under the application module. Edit this file and add the a public method to call the PL/Sql API. For more information you can check the developer's guide documentation . Now we need to expose this function . To do this edit the application module and go to Java tab. There click the pen for client interface. You should the newly created function on the left side. Select it and move it to right. After completing the previous step you should be seeing your function under Data controls. Everything is ready now. We need to create a page...

I started to work with the IDE 3 weeks ago. My company decided to migrate our existing forms application to ADF. My first impression with IDE was not so positive but it is still a preview release so I hope it will be better once released. I decided to write my experiences with this tool from now on..Lets see how it will be .. Wait me JDeveloper , I am coming to explore you !!
