Portal Components and Portal Services

[Former Member]

Hi,

When we are developing any webDynpro application, then how will decide either to use Portal Components or Portal Service or both of them?

Please give me an example...

Thanks & Regards,

Hi Vali

<b>PORTAL COMPONENT</b>

from user point of view,a component that can be displayed into a portal page.from an apllication development perspective,a plug able to component designed to be executed into a portal environment

<b>PORTAL SERVICE</b>

A component offering a globally accessible function in the portal.the portal runtime development model offeres a way to implement a clear separation between a Service

API and its implementation

A Portal Application contain <i>two types of resources</i> :

1)Web Resources

- Accessible via http / https requests to a web server

- All files Not unber WEb-INF

2)Non-Web Resources

- Not accessible via an http / https request

- All files under WEB-INF

A portal Application can contain:

a) Several portal components and several portal services.Using several sections in DD these components and services are defined

b)only <i>ONE</i> Portal Component

c) only <i>ONE</i> Portal Service

All portal services of a portal application are declared in service sections within the services section

A Portal Runtime application defines a collection of portal objects, which are of two types:

&#9679; Portal Component: Produces HTML output to be displayed in an iView in the portal, and is triggered by an HTTP request

&#9679; Portal Service: Provides a service, that is, some sort of processing but is not bound to a specific HTTP request

An application is a set of files – java classes, HTML, JSP and others – that define a set of components and services. The files are bundled and zipped into a single file with the extension .par. Such a file is known as a PAR file. Portal administrators upload PAR files in order to make the enclosed components and services available

A portal service can be used only when the portal platform is installed and the Web Dynpro application and the portal platform run on the same machine.

Even if you use a complete SAP NetWeaver installation (including the portal platform), you always have to use the local portal service. It is not recommended to use your Web Dynpro-based portal content within a global or federated portal scenario
