JCO/JCA

[Former Member]

Hi all,

I searched for JCO/JCA topics in the forum, but I confused some terms/usages about them. Could anyone clarify for me:

1. What is different between JCO and JCA? Does JCA have the api to programming as JCO? From EP 6, JCO is deprecated, we use JCA to connect to SAP instead, is it right?

2. With JCO, what is JCO Destination, JCO inbound, JCO outbound? When we need to configure JCO Destination?

3. If we develop a portal application (ex: JSPDynPage)/ a WebDynPro application to get data from SAP, do you need configure JCO (in SLD, in EP, ...) or we just need use JCO API in code? How do we configure it?

4. What is Adaptive RFC?

Hello

a short answer to some of your questions

1. What is different between JCO and JCA?

JCO is a SAP java library to connect to a SAP R/3 System. it can be used by independant (ie non-portal) application.

JCA, as i understand it, is a library whose structure as been defined by Sun, to connect to external system. The JCA implementation in the portal is based on JCO, and is to be used in the portal.

3. If we develop a portal application (ex: JSPDynPage)/ a WebDynPro application to get data from SAP, do you need configure JCO (in SLD, in EP, ...) or we just need use JCO API in code? How do we configure it?

If you use WebDynpro, you configue JCO in the WAS, and then use the plugins to create connections to R/3 RFC Functions.

If you develops standard Iviews (JspDynPage or Dynpage), you use the JCA api to get a connection to an alias, that itself point to a (R/3) system that has been defined in the portal administration.
