B2B ------------------------------------- This term is very frequent in the ERP, its refer to the transactions done by one business entity to other business entity. Like a tv manufacturing company is buying chip-set from one company and picture tubes from other company. These all are the example of the B2B transactions. B2C ------------------------------------- This term is less frequent in business world but irony is revenue comes from these transactions only. B2C refers to the transactions done between a legal business unit and customer. Like selling a tv to customer. B2G --------------------------------------------- Its refers to the transactions done between the businsess entity and Government. Simple terms its refers when a business entity do business with the government, or when customer of the business unit is government.  Now question may come B2C and B2G are almost same, yes both are almost same but the way business in these two handles a...

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.

Hi, Today I got stuck with the requirement where I had to display the parent and child in the input mode. My problem was I am having two VOs both are connected to each other using a view link and both are having the id column. This column is a primary key for the Employee table and foreign key for the Description table which in tern also have a id column. so my database schema is like this. EQUITY_USERS Name Null Type ------------------- -------- -------------- USERID NOT NULL NUMBER USER_NAME NOT NULL VARCHAR2(20) FULL_NAME VARCHAR2(20) ACTIVATION_FLAG NOT NULL VARCHAR2(10) DEACTIVATION_REASON VARCHAR2(2000) ADMINUSERID NUMBER LAST_UPDATED_DATE NOT NULL DATE ...

Some time we have come to scenarios when the validatity of the row is dependent over a column value of date type. A typical example of this is contractual employees, if the contract date is over we may not be interested these employees for the payrole. ADF provides a property effective date for this use case. Its quite easy to implement and in the VO by just setting a flag we can ignore these rows. For this example we are using default HR schema of the XE database, we will create a new table as the existing table does not solve our purpose. create table CONTRATUAL_EMP as select * from employees; alter table CONTRATUAL_EMP add (CONTRACT_END_DATE DATE); update CONTRATUAL_EMP set CONTRACT_END_DATE = sysdate -10 where mod(employee_id,2) =0; update CONTRATUAL_EMP set CONTRACT_END_DATE = sysdate + 200 where mod(employee_id,2) =1; commit; Now table is ready, We are moving to to project. please download the project from the link . Open this project and then run the page DisplayResult.jpx. No...

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 j...

This is the final post in continuation for the creation of the weblogic domain with the SOA support. In last two post I described component required and placement of the each artifact required for the creation of the SOA server. Now everything in place and we can start building a server which will support soa. There are two ways a SOA server can be configured 1. All in one Admin server 2. Soa server as a managed server to Admin server. In weblogic we can create a number of managed server under a admin server each of these managed server are like different serving point. In a cluster environment two or more managed server worked as a single unit, to increase availability. Each managed server can be controlled from Admin server and while startup it takes all the configuration related information from the Admin server. While for the study purpose its better to have a all in one admin server which take less resource to run and require less steps to shutdown or start, which we must have to ...

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
