Where to place business logic in the following case.
Hello
The user interacts with a button on the user interface. The business logic is to call a web service and do some simple calculations and then return the result in the same page.
The web service is already available on the server of the soa. Where should I put my business logic? Call POJO (who hold the business logic) managed a bean method related to the user interface button?
Create a service in AM method and call the pojo holding business logic? Business logic should go in the template project? If its model in how I access it on a click on the button in the view?
Please help and made me know the flow and the right place to include business logic.
Concerning
As its name suggests, the business logic belongs to the model layer. Separation of concerns must be in this case too.
You implement a method in the module of the application that does all the work and returns the answer to the view layer where show you. In this way, you can change the implementation without changing the substance of the user interface. The interface is the method with its parameters.
ADF allows you to call a public from the application module method as for example the commit method. You drag the operation of the data control to the page and drop it as a button. This will create the necessary liaison and a block on the button calls the method.
If you call a web service, a good practice is to wrap the web service in a pojo to add a layer of abstraction that you can then use to implement advanced logic. The pojo belongs to the model layer.

Where should write business Logic in ADF 11 g
Hello
I use JDeveloper11.1.2 and ADFbc in the model layer. If I want to customize the logic, where should write it.
Thanks in advanceHello
It depends on you, you can use your business Services layer to write your business logic, or you can write your business logic in your java class and as data control and use them at your leisure.
Another way is that you can write your own query and do as a non-updatablle VO and use it.
It will be better if you share some of your use cases, so I can tell you better.

Onload event management to add business logic to the JSF page in ADF
I want to know how to handle the onload event so that add us business logic once a view is loaded.
In short, that's what I want to achieve-
I have an entity object that I show as editable ADF table. Once the page is loaded and I want the table to show at least 4 tiers bit regardless of the number of lines now exist in the database table. For example, if the database table has 2 entries then table ADF should show these 2 rows and 2 additional lines in the table of the ADF. And if the database table has 6 ranks, it should show 6-row table of the ADF. How to programmatically manage this feature. What functions and methods, I need to replace or add. Any help is appreciated.

Set the following fields in 'read only' to take data from the first occurrence?
Hoping that this can be easily done without the need for scripting.
I'm working on creating a form of proposal. There are a few areas where I would like the first instance of an editable field, but the rest would be locked so that they are even taken out of the tab order.
Example: On the first page, I have a field for the name of the company. This field is reproduced in the pages of the proposal. Each field has the same name. So all data have concluded one of them are dealt to each of them.
Ideal solution: Front page field is editable, and is where data is entered. "All the following fields are defined as 'read only' and take their 'master' field data" so someone can't make a change to this form, for example, the third page and have this error repeated throughout the document.
Is this possible?
I use Acrobat Pro DC on Windows 7 pro.
Thank you.
You use a script to do it, but it's very simple.
If the 'master' field is called "Text1", then enter this code in the calculation script customized for all other areas that need to have its value:
Event.Value = this.getField("Text1").value;

You attempt to add a web form of Business Catalyst to my site Web of Adobe Muse (via insert html) and the shape is cut all the content below where to place the html area. I tried the basic troubleshooting and it's only when I insert a form of Catalyst Business that my web page is cut, where is the bottom of the form. I use this code when you insert form BC in Muse,
"< div class ="bulletin of information-form"> < form name ="catemaillistform58787"onsubmit ="return checkWholeForm58787 (this)"method ="post"action =" http://theincitejournal.BusinessCatalyst.com/CampaignProcess.aspx?ListId=53681& OPTIN = true & PageID = / index.html"> < div class ="form"> < div class ="item"> < label for ="CLFullName"> full name < / label > < br / > < input class ="cat_textbox_small"type ="text"name ="Full name"id ="CLFullName"maxlength ="255"/ > < / div > < div class ="item"> < label for ="CLEmailAddress"> E-mail address < / label > < br / > < input class ="cat_textbox_small"type ="text"name ="EmailAddress"id = '" "CLEmailAddress" MaxLength = "255" / > < / div > < div class = "item" > < label > Enter Word verification in box below < / label > < br / > {module_captchav2} < / div > < div class = "item" > < input class = "cat_button" type = "submit" value = "subscribe" id = "catlistbutton" / > < / div > < / div > < script type = "text/javascript" src = "http://theincitejournal.businesscatalyst.com/CatalystScripts/ValidationFunctions.js" > < / script > < script type = "text/javascript" > '
The only settings I did took the H3 header on opt-in and page navigation after the action to get rid of the opt in BC function as default. I tried to download the source code as well and I'm having the same problem. The web Page is here " copy " and a version of what I was creating the page to look like here is ' home ' As you can see, the 'House' version allows me to scroll past where I would have placed the shape box while the 'copy' stops at any user to parade before. I have called the shape slightly from the "development" of British Colombia under the style sheets tab and still tried to trouble shoot and get rid of the code to see if it affects something and it did not add style. For some reason only the HTML to the form is but I cannot understand what the section of the code would do that. Any ideas?
I see that you have inserted a script tag open that you forgot to close, which generates errors on the page and prevent it from be returned correctly. You should ensure that the code that you insert in the Muse is syntactically correct.

Once check this document by Chris Muir-Oracle ADF Code Guidelines
Normally any code that deals with the model model or the update must be written in the template itself
You can do that in AMImpl (implementation of Application Module class), for any specific code viewObject you can use VOImpl (ViewObject implementation class)
For any specific operation, create, update, or delete, you can make use of EOImpl class
and any validation level of page, for access to the UI component, the use of any script on the client side as a listener client or server listener, using iterator, listbindngs, bindings, call business services through link etc. layer you can make use of bean managed

Hello
I'm currently building the cluster by RAC 11 GR 2. I try to install Oracle Grid Infrastructure Oracle Linux 6.4 (x86_64bit) machine - node1.abc.com.
I'm at the stage of the "Cluster Node Information" where I have to provide me with the list of nodes to be managed by the Oracle grid Infrastructure. Currently I have added just me - node1.abc.com with the name of the virtual IP address - node1 - vip.abc.com. The two host name and virtual IP addresses are registered on the DNS server - it is also installed on node 1. Before adding the second node2.abc.com, I was testing SSH connection but it fails. I clicked the [SSH_Connectivity...] button and in the OS Username (grid) and his password. When I press the [Setup] button, it pops up message successful "Able to establish connectivity SSH without password between selected nodes." But when I click on the [Test] button or the [next] button, I get error - ' connectivity [INS-06006] SSH without password, do not put in place between the following nodes: [node 1].» What is the problem and what exactly to do to avoid this error?
Thank you
It was because I assigned a real static IP address for the second NIC eth1. With this affected YES wouldn't let you go to the next screen. So I had to remove NIC out of my laptop. But if eth1 is not resolved by the DNS name it also gives you errors. So I guess a correct functioning is I would sign up eth0 and eth1 to the DNS server but eth1 does not have real IP. Then I could go to the next screen.

Hello
This is my first time on this forum so bear with my ignorance! I'll expose the background of my setup and then explain the error.
We have a small business with a server running SBS2011 and PC running Windows 8 and 8.1 connected to the server in a domain environment.
We use a CRM product called Emu Tall that uses SQL Server 2008 R2 on the server for the database and the PC run a local application that connects to this database.
On a daily basis, but completely randomly and sometimes several times a day, a user will try and open the application on a PC and get the following error message.
Could not load file or assembly 'Microsoft.SqlServer.SqlEnum, Version = 10.0.0.0, Culture = neutral, PublicKeyToken = 89845dcd8080cc91' or one of its dependencies. The system cannot find the specified file.
At first, I thought it must be a matter of waiting time as it seemed to happen every morning, but I've proved since that it occurs at any time of the day and is apparently unrelated to amount of users or idle time or something like that.
Here's another oddity that hopefully sheds some light on it. If I go to the server and open the CRM application on the server, it works very well since it is only the PC that have the connection problem. In addition, as soon as I connected to the server of any PC can connect immediately (until it happens again later in the day). I don't need to stay connected to the server, connect one time and close the session and he "fixed" it for a few hours for all PC users.
I contacted the CRM vendor, and they are completely confused and have no idea what to do.
We are trolling along at the moment with me opening a session on the server for launch launch whenever a user receives the error message but it is far from satisfactory.
A final observation is that it does not always. It used to work fine. The problem began just two months ago and seems to coincide with the increase in our user from 5 to 12 users license even if the CRM provider swear that it is nothing to do with the license. They may agree; I don't know enough to argue the point.
Any help will be appreciated! I'm sure it will be a simple solution and someone there will know why and the answer immediately but is elusive at this time.
This issue is beyond the scope of this site and must be placed on Technet or MSDN
