Netweaver Data base instances for Java and ABAP

[Former Member]

Hello Experts,

Please help me to understand how the two technology stacks of SAP WAS (Java and ABAP) are configured to use underline data base in Netweaver.

Is it manadatory to have two separate data base schemas, one for ABAP applications and other for Java applications in the Netweaver?

If yes..the any idea about what are those schema differences??

Hi Rajan,

As Per my Knowledge for Java and ABAP have the separate schema id because they are separate programming languages,

For ther details please see in the below link

Thanks for the reply.

If these two databases have different schemas ,what is the effecient way to access tables on ABAP stack from application running on Java stack of Netweaver.

One way I know is to write a function module and expose it ot java application as a web service.

How can we access the same using JCo??..

Hello Krishna,

Thanks for the reply.

Is there any way I can access these shemas? Are they the same by structure or there are major differences?

My requirement is to build a common schema out of these two and have the data from these two schemas to be consolidated in the new schema.

Any help will be greatly appreciated.

Schema for ABAP and Java are separate and cannot be combined. But SAP provides

a way for Java to call ABAP schema via persistence APIs
