I am a J2EE (Java) developer with good OOP background. Now, I am interested in learning the integration tech of SAP with Java. While browsing through the site, I understood that SAP NetWeaver has come up with this new feature. I also encountered few other tech used which I am confused with.
1. What is SAP Java Connector? Is it used in NetWeaver for the Java and ABAP interaction?
2. What is SAP Java Resource Adapter? Is it used in NetWeaver for the Java and ABAP interaction?
3. How is SAP Web Application Server related with SAP NetWeaver?
4. What is Web Dynpro application?
5. Is it is essential to have basic ABAP knowledge (there by SAP knowledge) to work with these env? is it is a right starting point?
Kindly guide me. Your help in this regards would be highly appreciated.
