Java to SAP

Hello,

I want to built an interface to a SAP R/3 software without using the Java Connector (JCo) or something similar.

I know that it is possible to call SAP BAPIs with remote function calls, I tried it with JCo and it worked, but I want to built this without using JCo.

I read about using RMI or J2EE Connector Architecture but I really have no idea how to use it an weather it is possible or not.

Can you help me? And do you have some examples?

Many thanks,

Claudia Stephani

    Hi Claudia,

    RMI is Remote Method Invocation and works between different JVMs. On R/3, you do not have a JVM, so that's not the way...

    > without using the Java Connector (JCo)

    That's OK, nobody forces you to go this way...

    > or something similar.

    Hm. JCA could be called "something similar". It's just that it is a general architecture, not bound to a specific kind of backend implementation.

    > I really have no idea how to use it

    See https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/jca on ep6 building portal applications.zip for an introduction including some example (based on EP).

    > and weather it is possible or not.

    It is! Have fun!

    Hope it helps

    hello

    there is an j2ee resource adapter available from sap (beta version) which supports java -> R/3 (rfc) communication

    take a look at: service.sap.com/connectors

    ( but this is still not without jco, because the layer under the j2ee connector is jco )
