Hi Sunny,

You have to learn Java SE Technology (JDBC-Java Data Base Connectivity).

Through JDBC API you have to handle SQL DML (Insert, Update and Delete), SELECT statement, Join operations etc.

Read this links.

Before applying JDBC in WD for Java application try to create a small java application using JDBC APIs.

Hi,

Core java is must.

JSP is not needed as such in your project.

For better design of your application, use EJBs for connecting to backend. In the sample web dynpro tutorials you will find example of such application.

Note: In latest release of Netweaver (CE) you will find EJB Model which can be very useful for you application.

So knowledge of EJBs will be advantage.

So to summarize => See core java, JDBC, EJBs and Web Dynpro .

[You might not know web services in detail but you might like to use that in your project. See sample application for such examples]

Vidya

Hi Sunny

First you need to understand Webdynpro framework it is totally for presentation.

you can get help of these from the tutorial.

coming to your project, you are using Oracle as backend. For effiecient use you can create EJB's for all your database operations, this becomes your business layer.

Then, you need to learn use these EJB's from the presentaiton layer i.e. webdynpro, you can find tutorials in SDN.

Hope this clears.
