For developing enterprise portals through SAP Netweaver using JAVA we need to use the packages,classes or interfaces provided in the API.

There are various APIs provided by SAP to help in development of Netweaver applications using JAVA.

Here I will try to discuss Enterprise Portal APIs. They are used in development of enterprise portals.

The following three APIs are most commonly used while developing an Enterprise portal:-

1. Enterprise Portal (Enterprise Portal Runtime and Services API)2. PCD (Portal Content Directory API)

3. HTMLB (HTML Business for Java API)

There are various packages in Enterprise Portal API which provides classes and interfaces forimplementing Portal runtime, Page builders, wizards , dynamic system resolutions etc.

We will discuss few useful classes and interfaces generally used in EP development.

Interface IPortalComponent

It is present in package com.sapportals.portal.prt.component

All Portal Components implement this interface either directly, or more commonly by extending a classthat implements this interface.

It is implemented by class AbstractPortalComponent class.

This interface contains 3 methods :

1. init() - The container calls the init method each time this Portal Component isloaded in memory. It is deprecated in the new versions.

2. destroy() - The destroy method is called each time the PRT (Portal BuilderRuntime) decides to discard this component. After this garbage collector comes

into action.

3. service() - This method is called for each request that the Portal builder runtime

routes to an instance of Portal Component. Multiple threads may be executing

within the service at any time. It processes the clients requests. Animplementation of the IPortalComponent interface can have access to the request

and the type of request sent by the client.

publicvoid service(IPortalComponentRequest request, IPortalComponentResponse response) throws PortalComponentException

request parameter clients request

response parameter- servers response

Class AbstractPortalComponent

It is present in package com.sapportals.portal.prt.component

AbstratPortalComponent class implements following interfaces :

IEventListenerComponent IPortalComponent

IPortalComponentInit

It provides portal Edit, Help etc modes.

For this it has many methods like doHandleEditData(), doHelp(), doPreview() and many other methods.

2 Creating a simple portal application project

We will create a simple portal application project and then we will use this project to create iView, page

and roles on EP.

2.1 Create a Portal Application Project

Open Netweaver.

Click the Create Portal Application Project icon or use menu path.

File -> New -> Other -> Portal Application -> Create Portal Application Project

Enter name of project and directory where you want to store the project and click Finish.

Now click on icon Create Portal Application Objects

Now select the project you created and click next.

Select Abstract Portal Component and click next.


5/29

Enter name, class name and package name.


6/29

Click on finish . Then add following code as given in figure. Most of the code is auto generated.

package test.hello;

import com.sapportals.portal.prt.component.*;

publicclass HelloTest1 extends AbstractPortalComponent

{

publicvoid doContent(IPortalComponentRequest request, IPortalComponentResponse response)

{

response.write("First portal application project demo");

}

}
