What is relation of Business component and EJB3?

Hi
Thank you for reading my post
I saw that we can use Business components to make data driven pages very easily
can some one explain me , what is relation of Business components and EJBs ?
Does business components use EJB 3 ?
What about toplink , Does Jdeveloper provide better tooling for toplink persistance or EJB 3 persistance ?
Thanks

ADF Business Components is a Java framework we developed at Oracle to make development easier.
ADF BC doesn't use EJB 3.0 - and on a certain level it is an alternative approach to EJBs.
To see what ADF Business Components offers you out of the box to make you more productive read chapter 4 of the ADF Developer Guide -
http://download.oracle.com/docs/html/B25947_01/bcintro.htm#sm0051
The bottom line is that when you use ADF Business Components you end up writing less code.
With ADF you can use either ADF BC, EJB, or TopLink to build your application.
In terms of mapping capabilities - we currently offer richer and more visual mapping support for TopLink then for EJB 3.0.
Note that when you use EJB 3.0 and you deploy it to Oracle AS you are actually using TopLink as the JPA implementation.

Business Service of PI7.0 is now Business Component of PI7.1 with the same functionality

What is the different between component and component type in extract struc

Hi All,
What is the different between component and component type in the Extract Structure?
I used them, but I never really know the different between them yet.
Thanks,
Grace

The difference between Component and Component Type are:
Component This is essentially the field name in the extraction structure. These can either be SAP delivered field names or custom field names (e.g. Y* or Z*).
Component Type This defines the data definition for the field, along with associated attrributes and descriptions for anything using that Component Type, to define the corresponding Component. If you double-click on any Component Type in an extraction structure, it will show you the definitions that have been setup for that Component Type (will display as Data Element but it's essentially synonymous - Component Type refers to structures and Data Elements refer to tables).

Relation between business process and functional area during the role search

Hi Experts,
We have 2 functional areas in which we have different business process involved.
During the Access request, if the user selects one functional area then business process related to that functional area should come.
Is there any functionality in GRC, where the mapping between functional are and business process to be done?
Thanks,
Sriram

Hi Sri,
there is relationship between 'Business process' and 'Sub-business' process as in configuration parameter you can setup that once business process is selected only relevant sub-process will be selected.
There is no such a relation between functional area and business process.

CRM Architecture: relations between business roles and transaction

Hello Experts!
I am dwelling on the topic of the relations between Business Roles, Transactions, Transaction Types etc. Do you know if there is any architectual diagram to make clear how these objects are related, and how they depend on each other?
Thank you for help!
Karolina

Hi Javier,
As far as I understand you want to restrict transaction types per business role.
You can achieve this by customizing. You can create a transaction profile in customizing for each business role and assign the transaction types you have created to this transaction profile.You can find this customizing activity in spro transaction.
Then you can assign transaction profile you have created to your business roile by assigning function profile 'transaction profile' to the business role in crmc_ui_profile tcode.
In this way when you login with the business role the transactions you have maintained in transaction profile will only be shown up in the pop up.
I hope this helps yiour requirement. Let me know if you require any further information. Thanks.

Relation between business area and materials

I have to extract the materials given the business area , can i use these the tables t134g and mbew for that . Both have common field valuation area , t134g has business area and mbew has material number in it. I appreciate your responses.

Hi Deepthi,
You can directly use MBEW table to retrive Materials for a particelar valuation type. No need to use MARA.
Like this..
Select MATNR from MBEW where BWKEY = 'Put valuation area you want'.
Reward points if helpful.

What is the difference between component and sub-assebly?

Experts,
What is the diffence between sub-assembly and a component?
in my report if user enters component it should display sub-assembly. if it is reverse should not get component for that.
is there any function module for this?
I tried in CS15 but not get exact information.
please help me...

Hi,
component is nothing but one of small product. So many no.of products could combine and they will give one big product. For that particular component one or more sub-assemblies can be used.
Sub-assembly will contain one or more no of small contents.
14' inch boltnut is one of sub-assembly for the one big component.
In that boltnut sub assembly might contains bolt , nut and washer. That is called sub-assembly.
Thanks,
Shankar

In Short we use Business System when we have all details about the system and can mark it easily in the System landscape.

Error JBO-33003 ADF Business component as an EJB remote

Hi,
I need to deploy an ADF application (model in business component and view in ADF Faces) in a multi-tier architecture. I deployed the MODEL project (bc4j) in an OAS’s OC4J instance. Now, when I try to test de application I get the following error:
oracle.jbo.ConfigException: JBO-33003: Connection name <my_conn_to_oas> not defined.
Also, I tried to connect to de EJB session from my VIEW project, so I changed the file DataBindings.cpx. I changed the line Configuration="AMProyectosLocal" to Configuration="AMProyectosAS_DS".
When I run the view project I get the same error:
500 Internal Server Error

Please, help me.

Thank for your help.
I reviewed the datasource configuration and it is Ok.
The connection’s name isn't a datasource name. It is the connection’s name to the APPLICATION SERVER. I reviewed the bc4j.xcfg file and it has the following definition:
<ConnectionDefinition name="AppServerPenny">
<ENTRY name="remote-oracle-home" value="/home/oracle/OAS/10.2.0/middle"/>
<ENTRY name="ConnectionType" value="Oracle_AS_10g_UNIX"/>
<ENTRY name="HOSTNAME" value="penny.asesoftware.com"/>
<ENTRY name="DeployPassword" value="true"/>
<ENTRY name="oc4j-instance-name" value="OC4J_ARES"/>
<ENTRY name="user" value="ias_admin"/>
<ENTRY name="ConnectionName" value="AppServerPenny"/>
<ENTRY name="ormi-username" value="admin"/>
<ENTRY name="ormi-client-url" value="ormi://penny.asesoftware.com:23791"/>
<ENTRY name="IIOP_PORT" value="1810"/>
<ENTRY name="password">

</ENTRY>
<ENTRY name="ormi-password" value="manager123"/>
<ENTRY name="DeployPassword" value="true"/>
</ConnectionDefinition>
Why does the test utility not found the AppServerPenny connection?

Why business component does not support generics method parameter

Hi Folks,
I have created a business component and in this business component I have added a public method which takes a parameter - List of map (Like List<Map<String, String>> inputListOfMap). Now when I try to run the artifacts for this business component it gives an error
ERROR
com.splwg.shared.common.LoggedException: No method declaration for createListElements found matching argument types [List, Element, String, String] with pattern public\s+(final\s+)?(<[^>]*>\s+)?([\w\.]+)\s*(<[\w<>,\s\.]+>)?\s+createListElements\s*\(\s*((\w*\.)+)?(List)(\<[^\>]*\>)?\s+\w+,\s*((\w*\.)+)?(Element)(\<[^\>]*\>)?\s+\w+,\s*((\w*\.)+)?(String)(\<[^\>]*\>)?\s+\w+,\s*((\w*\.)+)?(String)(\<[^\>]*\>)?\s+\w+\s*\)\s*(throws [^\{]+\s*)?[;\{]
After checking the spl-tool2.2.0 jar class JavaSourceFile.java i am guessing that such method parameters are not supported. It compiles well if its a simple Map or List. Also works fine if I make the method as private. But in this case I cannot use this method from any other class... which I don't want.
it would be great help if anyone can suggest what needs to be done to overcome this issue
Following is the method of Business Component
public void createListElements(List<Map<String, String>> inputListOfMap, Element sourceElement, String groupName, String listElementName) {
          logger.info("createListElements ");
          Element groupElement = null;
          Element listElement = null;
          if(!isBlankOrNull(groupName)){
               groupElement = sourceElement.addElement(groupName);
          if(notNull(inputListOfMap) && inputListOfMap.size()>0){
               for (Map<String, String> inputMap : inputListOfMap) {
                    //If group name is provided then put the list element will be within the group element else within the bill element
                    if(notNull(groupElement))
                         listElement = groupElement.addElement(listElementName);
                    else
                         listElement = sourceElement.addElement(listElementName);
                    for (Map.Entry<String, String> mapEntry : inputMap.entrySet()) {
                         String elementName = mapEntry.getKey();
                         String elementValue = mapEntry.getValue();
                         if(notBlank(elementName) && notBlank(elementValue)){
                              listElement.addElement(elementName).addText(elementValue);
     }

Hi Victor,
the issue is that the archive pool in your NWDS is not set up properly. Could you check the configuration of the development configuration? I guess you are developing in Local Development, right? Please check in the "Component Browser" that the two Software Components "NWMCLIENT" and "XOCA" are present and contain some DCs inside them. If this is not true, than something went wrong with your setup of the IDE. The modifications of the default.confdef are most likely not right.
Please come back to me if you don´t know how to proceed.
Regards,
Stefan
