Can anybody point differences(advantages/disadvantages) between a)calling a BAPI using JCo b)creating a web service for the RFC and calling the webservice fron WD application.

Hi Bhupesh,

Jco is written in java and it convert the java calls into the native ABAP calls ..so comunication is done between a java program and r/3 system through the JCo.....if the BAPI is exposed as a webservice ..then the processing language use is XML and SOAP protocol any language which can create and process XML can communication to BAPI(r/3) system...like java,dotnet etc....else u need a middleware like JCO which can convert java calls to abap calls for that language ...and now a days ....XML is commanly used by most of the Internet technologies...

hope this will clear ur doubt.

Thanx Yash.

So,if I want to call a BAPI from my java/WD application,I publish the BAPI as a webservice rather than using JCO.

In this case how is the authentication to the R/3 going to take place?Can you point out some links describing how to do it?

thanx,

Bhupesh
