Hi Aarti

First of all welcome to SDN Network and now about your question.

There are many fields you can work with. Java development is used in various components of SAP Netweaver. You can also look to the EP Content Development area on SDN if you are ineterested in Enterprise portal development using Java. Else Java programming is used in various different application development. There is Java development area in Netweaver Developer studio in Java perspective. You can also use J2ee perspective for making J2ee applications. There are Various API provided by SAP which you can use to interact with various components of Netweaver.

> Why do we need two different engines defined in the diagrams explaining the SAP Netweaver architecture?

I have once answered this question earlier. Please refer to the link:

If you are interested in the things like web developement then you can work in Web Dynpro (used in UI development and provide a wonderful way of Web Development, Based on MVC architecture).

There is few more options. What you have to work on depends on you:

1) You can work in simple JSP and J2EE applications.

2) Portal Project using HTMLB in JAVA (JSPDynPages).

3) BSP(Business Server Pages), this interact with SAP system very effectively.

You can do UI(User Interface) development using all these Option and use various techniques for integrating with backend R/3 system.

If you have any speacific doubt feel free to ask

hi aarthi vijayaraghavan,

<b>Same pinchh.....</b>,

I was also new to sap Netweaver from Java background. similar question have kicked me when I entered this work area.

to my knowledge Java is the basic foundation for Sap Netweaver because of its Wonderful features like platform independence which you know.

The workarea of Netweaver is NWDS, which is nothing but Eclipse.. Hopefully basic knowledge of Java,JSP,Javabeans and understanding of MVC architecture is enough to start working on Netweaver..

Hi Aarthi,

JAVA is widely used in SAP Netweaver world. Earlier JAVA was not necessary for SAP but after netweaver it broadly used at many places. We have two engines in Netweaver that is ABAP engine and JAVA engine. EP is almost based on JAVA only. You have to do coding in JAVA for portal application. In XI we have JAVA and ABAP stack. We need to install JAVA web start to run the XI server. Even user defined functions are build up using JAVA codes.

For more on netweaver go to the homepage of Netweaver where youwill find all the details related to it:

Check this index of SAP for Netweaver:
