Current Logged in User and Roles in ADF and Fusion Apps



A) Using the groovy Expression.

We can set default expression in view object attribute as below 
adf.context.securityContext.getUserPrincipal().getName() 
adf.context.securityContext.getUserName()  


 For Roles use 

 
adf.context.securityContext.getUserRoles()



B) Java Code
You can get User Name in Java code also using the following code.

     ADFContext adfCtx = ADFContext.getCurrent();  
     SecurityContext secCntx = adfCtx.getSecurityContext();  
     String user = secCntx.getUserPrincipal().getName();  
     String userName = secCntx.getUserName();

     String[]  Roles = secCntx.getUserRoles();

C) Expression Language
You can bind ADF Faces componenets with the following EL to get logged User Name.

 #{securityContext.userName}  
 #{securityContext.userRoles}

D) In Fusion Applications (On Premise Implementation)

      ApplSession session = ApplSessionUtil.getSession();
      String guid1 = session.getUserGuid();

Executing a method bindings In Bean method.

Image
Many time you be in a situation where there is a AM method exposed as a client and requirement is to execute that AM method from the backing bean. Its quite simple first you have to register that AM method in the page definition file as method bindings. Now choose the method you want to add to the page definition and executed by a bean method. for the parameter either you can use the bindings if your parameter clearly coming from bindings else leave them blank. Now in the bean method first you have to catch the handle of the DCBindingContainer and then using this binding container you can get the operation binding for the AM method and then can add the parameter. If you are have already bind the parameter with the bindings then can skip that. then you just need to call the execute method of your operation binding.

Using Java Decompiler(JD) with Oracle Jdeveloper (Jdev)

Image
  Java Decompiler(JD) with Oracle Jdeveloper (Jdev) Java Decompiler is a good tool to check the code, when we just have complied code.  There are ways by which you can check the code, which is been in form of jar with you.   Let say you got ADF Jar file for a project and now want to check, what is the code inside of an entity object IMpl or how this code is structured.  There are some simple steps to it. 1. Create an ADF application with mode and UI project. If you have more project, try to keep the name of the model same as jar. Here I have two jars to check. employee Model.jar and employeeUI.jar.   2. Now go to you jars and then unzip these jars using the unzip or 7 zip prog. 3. Once you done with the unzip then place these directries under the application and project you have created. Please have model code paste under src directory only. 4. Refresh the application now and you will be able to see new files under the project.

Current Date in ADF.

Image
In adf a number of places you want to set the currentDate as a default parameter, you can use the groovy expression to set this. Like for a bind parameter if you want to set the default value use the value option and set the currentDate from the adf. In case if you want to set the value less then 10 days to current date you can use it adf.currentDate -10. This will give you date 10 days less then current date. If you want date and time both you can use adf.currentDateTime. In some of the cases you may need to execute the custom methods defined in your entityImpl then you need to use adf.object for that. Like in the below case if a custom method has been coded in the entityImpl to get the default value like getDefaultDepartmentCode. If you need to set the same for your variable you need to use it adf.object.getDefaultDepartmentCode
