ABAP & JAVA stacks

[Former Member]

There are lots of post regarding ABAP & JAVA stacks. I am not sure if I see a consolidated answer anywhere. Also I don't see overall architecture diagram explaining just the stack part.

Here is my understanding after reading/researching, forums, help, blogs and other documents.

<b>ABAP Stack:</b>

-Integration Engine (IE) {This is where the message pipeline happens}

-Business Process Engine (BPE)

-ABAP Mapping

-XSLT Mapping

-IDOC Adapter

-Http Adapter

<b>Java Stack:</b>

-Adapter Engine (AE)

-Integration Builder, SLD, RWB

-Standard Mapping

-Java Mapping

-XSLT Mapping

Is this correct, am I missing anything else?

Thanks

Isn't that <b>RFC ADAPTER</b> uses both <b>ABAP</b> and <b>JAVA</b> stack>?

cheers,

No, it doesn't.

RFC Adapter is entirely Java-based (based on the JCo API).

JCo itself is based on both Java and ABAP developments.

Thanks Vijaya and Michal.

I updated my orginal post on your comments.

Anyone else would like to add more to this, if not I will close this post by end of the day.

Hi,

IDoc and HTTP adapter are on ABAP stack all other Adapters are JAVA stack, Since IDoc and HTTP adapter are on ABAP stack they no need sender agreement.IR,ID,SLD,RWB are in Java Stack.

Hi,

Maybe you can also add cache's integration directory, bpm and repository to ABAP and CPA cache to java. But maybe it's not related to your question.

That is interesting, can you please explain a bit more.

Are you saying that the cache of integration directory, bpm and integration repository is stored in ABAP stack and CPA cache is stored in JAVA stack?

[Former Member]

yes
