Hi Ajay,

To connect to R/3 system from WAS you have to set up the SLD (System Landscape Directory) and configure the same.You have to create JCO connections also to connect to R/3.

Please check the following link to know more about SLD and configuring the same.

Hi Ajay,

If you have SAP WAS installed,you have to establish a connection to R/3 database, using JCO connections.

one way to connect to R/3 is

http://<server>:port/webdynpro->; logon with valid userID and Password you will be directed toCreate JCO destination and check sldConnection here you can establish connection to R/3.

Hope this info helps you

Hi Ajay,

If you want to call some BAPIs from your SAP R/3 and that R/3 system is already available then there is no need to install ABAP stack. You can work with only JAVA stack.

You can use RFC model in case of Webdynpro application or you can use JCO connections from any other java applications like JSP. servlets etc.

So, using this facility you can call BAPI on any SAP R/3 system and these R/3 systems are independent of the WAS JAVA stack.

SAP WAS has two engines, one is java engine and the other is ABAP engine.

For you to write java code you need the java engine, for BAPIs you need the ABAP engine. For connecting from java to ABAP you need Javaconnector.
