Benny One Quest on Basic ABAP and Java

[Former Member]

Benny,

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.

Regards,

Arun.

Hi Arun,

I'll try to answer your questions:

>

> 1. What is SAP Java Connector? Is it used in

> NetWeaver for the Java and ABAP interaction?

That's a library which is used to do exactly this, connect java and abap. And yes, it is used in NetWeaver heavily.

> 2. What is SAP Java Resource Adapter? Is it used in

> NetWeaver for the Java and ABAP interaction?

The Ressource adapter is a JCA compliant Adapter, that will be delivered in the future (currently beta). Nevertheless for pure functionality it is using JCo again, as JCA does only take care of Connections handling and such, but not for functionality.

> 3. How is SAP Web Application Server related with SAP

> NetWeaver?

It's the basic Server that runs everything inside NetWeaver, which is our technology platform.

> 4. What is Web Dynpro application?

WebDynpro is a technology for HTML/Javascript front ends, which can use arbitrary back ends as business logic.

This depends on what you're doing. To run and modify SAP applications such a ERP it definitely is a good idea to know ABAP.
