Requirement – How to Create a UCM custom component

Solutions- Please follow the below steps –

Starting the componentWizard – CD to the path where the component wizard is.
[[email protected] ~]$ cd /oracle/Middleware/user_projects/domains/ucm_domain/ucm/cs/bin // this path will of your weblogic domain
[[email protected] bin]$ ./ComponentWizard

1. Goto Options -> Add
You get the below window.
Fill in the component Name. Click OK.

Resources created
demo_component_resource.htm
demo_component_service.htm
demo_component.hda

Modify the resource.htm as below. Give the Service name, handler name and search order.
The handler name is the fully qualified name of the java file where the service method (printTheName()) is created.

Place the compiled java class file in the classes folder inside the custom component.
cs/custom/demo_component/classes/de/xyz/ucm/service

Fetching server name and port number for ADF application

Requirement – How to get server name and server port.
Solutions- You can get this information in by writing below code in java

FacesContext fctx = FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest) fctx.getExternalContext ().GetRequest ();
String serverName = request.getServerName();
int serverPort =request.getServerPort();

System.out.println ("Server Name:" + serverName);
System.out.println ("Server Port no:" + server port);

Difference in RowCount Vs EstimatedRowCount Vs FetchedRowCount in ADF

Being an ADF developer,there are few method which is very confusing .So lets discuss method which fetch row count of VO>
Sometimes in ADF applications, we need to count the number of rows, as shown in the table .If we don’t understand these method , it will create a big performance problem.

getRowCount() -> getRowCount() retrives all the records from View Object by executing ViewObject Query.The count is calculated by traversing the Viewobject using next() method until the
last record is retrived. This method hinders the performance of application in case of VO with large number of rows.

getEstimatedRowCount() -> When you need to get quick count of row.Use this method. Method getEstimatedRowCount() actually retrives the count by hitting getQueryHitCount() which runs the select count(*) on the VO query.

getFetchedRowCount() -> Method getFetchedRowCount() counts the number of rows from the Result Set.Returns the number of rows fetched at that point of time.

In Short –

-> When you need to iterate all row to get or check some attribute value use getRowCount().It can create problem issue.
-> When you just need an count of table use getEstimatedRowCount().

If the application, we need to traverse the rowset all records, such as some of the above every line to get attribute values, you can choose to use getRowCount () method;
And if we only need to know the number of rows set the time, then use getEstimatedRowCount () method,
