What is the difference between EP and webdynpro?

What is EAR and how do we deploy Webdynpro ?

Is there any change request system in EP and WD like in R/3?

Hi

Let me have a go at it .........

Enterprise Portal : Provides role based access to your content i.e., who should get to see what.

Please go through the link for EP :

http://help.sap.com/saphelp_nw04/helpdata/en/a4/76bd3b57743b09e10000000a11402f/frameset.htm

Web Dynpro : It is one of the methods to create a content to be displayed in portal.We have other ways to display content in portal like BSP, JSP Dyn page etc.,

<b>From Help.sap:</b>

With Web Dynpro, you build professional, highly interactive, Web-based, and accessible user interfaces for business applications. With the portal, you provide role-based, secure access to any kind of information (structured or unstructured), services and applications via a Web browser. In SAP NetWeaver, these two technologies converge, enabling you to run Web Dynpro-designed content in iViews from within the portal.

EAR is a Enterprise application archive and it is deployed on to the WAS server through your Software Deployment Manager.

Thanks & Regards,

Vijith

EP :

EP Development consists of developing applications (known as iViews) that run in the Portal. These applications are typically built using Java technologies such as J2EE (JSP or Java Server Pages and EJBs (Enterprise Java Beans) , Web Dynpro, HTMLB for Java, XML, Web Services and more. Some development is also done using the PDK for .Net. The applications have to be able to run in the Portal, which runs on a Web Application Server, a J2EE engine that uses the Portal Runtime and, optionally, a Web Dynpro runtime

Hi,

It will be a very lengthy, if i start about EP and Web Dynpro.

You can get ample information about EP and Web Dynpro in

http://help.sap.com

<b>EP</b>

EP usage type contains the following components:

Portal: Serves as the front end of SAP NetWeaver, offering a single point of access to SAP and non-SAP information sources, enterprise applications, information repositories, databases and services in and outside the enterprise—all integrated into a single user experience.

Knowledge Management: Provides role-based access to unstructured information from various data sources. The unstructured information can be in many forms, such as text documents, presentations and HTML files, and can be viewed via iViews in the portal.

Knowledge Management makes use of the standalone engine TREX to perform search and classification operations.

Collaboration: Provides services that help communication and cooperation among colleagues and others in the enterprise. Services include virtual rooms, groupware integration, asynchronous and real-time collaboration tools.

Guided Procedures: Provides a framework for modeling and managing processes that involve access to multiple backend systems. It enables runtime collaboration and execution of ad-hoc items, as well as invocation of different types of applications and services within a process. The framework implements role-based access to tools, resources and process steps.

<b>Web Dynpro</b>

Web Dynpro is the SAP development environment within the SAP NetWeaver Developer Studio for creating professional Web user interfaces (UI) for business applications. Its model-driven approach minimizes manual coding and uses visual tools to design and reuse UI components. Web Dynpro is based on a powerful and flexible Model-View-Controller architecture that ensures a clear separation of user interfaces and backend services. Developers have full control of the generated code at all stages of the development process.

The Web Dynpro tools support application developers during the implementation and design phases. When a Web Dynpro application is developed, a platform-independent metamodel is created. With Web Dynpro for Java, Java classes are generated from this metamodel and used within a servlet.

Web Dynpro combines the strengths of the GUI/Dynpro approach offered in SAP R/3, including such features as dictionary-based field validation and error handling as well as seamless integration in a software lifecycle and distribution infrastructure to handle all installation, upgrade, administration, and monitoring tasks, with such Internet innovations as worldwide access, and integration of arbitrary content via hyperlinks.
