Can ABAP program and a Java apps access the same DB table?

[Former Member]

If an ABAP program and a Java apps access the same DB table, how does the Enqueue services from ABAP and Java communicate with each other to ensure locking consistency (if they even communicate with each otehr at all)?

Or there wont be such situation because there are separate schema for ABAP stack and Java stack?

Your help is greatly appreciated.

short answer: they don't. It's forbidden. Completely. No sharing of tables.

Correct. Every stack has it's own schema. If you want to access ABAP data you got to use BAPI/RFC.

Hi frd,

If ABAP and Java stack having different tables then to access transactional tables Java stack have to call ABAP BAPI/RFC then it will decrease the performance of java application, calling BAPI/RFC from Java and other application id one and the same.

How does the java development will be advantageous for SAP?

For business software development it is not advantageous for SAP at all. But there are several other areas:

-for customers who want to use Java.

-for any development that goes near system level.

-future development (most new technology projects are written in Java)

Hello!

A while ago I was a subject to criticism too for not granting points to helpfull answers. I appeared to be ungratefull, but I'm actually not (I guess the same goes for Vincent). I absolutely agree that good people who provide helpfull answers deserve (at least) points, but I didn't quite get the whole idea with points untill I was explicitly warned. I took some time to correct this and I granted points for all my past questions, generously, with "interest rates" for waiting.

My point is:

The pointing system is good, but unintuitive and not documented. I suggested this at that time, and I see that nothing has changed since. I see also that I'm not the only one who has experienced missunderstandings.

I repeat the message to SDN people: Please provide some info on pointing system! A few sentences behind a "What's this?" link would do. It's not such a hard work.

Thanks!

Kind regards,

Hi Igor,

thanks for this hint. I gave you points this time for that valuable information. I'll check with forum personal to provide that.

Benny
