ADF Simple Questions

Managed Vs Backing Bean


This question is almost asked in every jsff interview but yet there is quite confusion between two, I am putting down the difference between two

1. Managed bean will always be initiated and registered by adfc-config.xml.

2. Managed bean may have bindings for a number of components scattered though the project while Backing Bean must have the bindings only for a single page.

3. Scope of the backing bean will always request, while managed bean can be some of the different scopes.

4. Backing bean can be generated and self updated by option expose binding while creating a page. Jdev itself will add the binding of each component when you add it on page.

5. Backing bean most of the time overhead to the project as unnecessarily every binding is exposed.


Logs in jdev (Integrated Weblogic)

In jdev if debugger is on then a lots of logs are generated by jdev. Now sometimes if user want to go throw the logs or want to parse the logs then we can use inbuilt feature of the jdev to generate the logs at the user defined location.

You can do it by Tools --> Preference --> Environments --> Logs

Now check the checkbox of the "Save Logs to File". Now choose the directory where you wants logs to be generated. It can be any directory which is accessible from the machine where jdev is installed.

Executing a method bindings In Bean method.

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 ...
