<b>What is the difference between Webdynpro and portal development Kit? </b>
Hi,
<b>WebDynpro</b> is a highly declarative, tool-based programming model. It minimizes platform-dependent "plumbing" code for building UIs and maximizes declarative metadata describing huge portions of a typical application in a platform-independent way.
Web Dynpro follows a "top-down" approach in order to consistently support multiple runtime platforms.
In Web Dynpro you just do drag & drop the UI components.
Portal components has followed a "bottom-up", programming-driven approach to Web development.
<b>Webdynpro</b> is used when requirements ask for a prototype using minimal time n effort.
Highly skilled programmers are not necessary to write a webdynpro application
It uses dynamic controls without reloading the page.
<b>The Portal Development Kit (PDK)</b> provides documentation and examples with source code to demonstrate how to develop portal applications and portal content for the SAP NetWeaver Portal using the SAP NetWeaver Developer Studio.
PDK includes coding examples on the following topics:
*Creating Portal Components and Portal Services
*Portal Profiles
*Resources
*Internationalization
*Portal Beans
*Page Builder
*EPCF
*Application Integrator
*Connector Framework
*Portal Navigation
*Object Based Navigation
*Transformation Service
*User Management
PDK is for deployment for portal application, has very good documentation of portal development, contains sample application, Java Docs for all the apis for portal and KM and plugins for eclipse(which you don't need if you are using NWDS). It is basically a nice help for developer along with an iviews for uploading par and testing them.
In EP 6.0 it is just business package that you import to your portal. This will then give a "java development" role in portal which can be assigned to users. The role will then create a tab called "Java Development" in the top navigation and click on it you can see all the contents underneath.
Regards,
Pooja.

Hi Pooja,
Could you pls let me know, what is the latest PDK available in market for EP7.0, is it needed at all. I was wondering whether this is the only way a 'javadeveloper' role is got, also it is my understanding that PDK is required for viewing the trace/log files. Am i right in this or am i missing anything here ?
Thanks in advance,
Anupama
