How to configure JCO's to connect ABAP and JAVA systems

[Former Member]

Hi every one ,

We installed SAP NETWEAVER 7.0 Support Release 3 ABAP stack with oracle database. Next we installed JAVA stack on the same system. Now we want to connect both the systems using JCO's. Please tell me the prerequisites for configuring the JCO's and also the steps.

Is SLD(system landscape directory) should be configured for configuring JCO's

Regards,

Mahesh

Hello Mahesh,

You can create JCo in Java for destination ABAP without SLD.

Visual Administrator > server<x>> services--> JCO destiantion

Please take a look at below help link for more details.

Hi,

Actually don't create jco connection through the sld as that can lead to issues. The correct way to create jco destinations is through the web dynpro content administrator.

http://<hostname>:<port>/index.html from there -> Web Dynpro Tools -> Content Adminsitrator

Then as long as your sld is up and running you can create jco connections.

Kind regards,

Hi

You can do it thru SSO, exchange of certificates between ABAP and JAVA stack.

In ABAP stack,

TRX : Strustsso2

select 'System PSE' > Right click > 'Create'

Accept the details and click ok. You will see that certificate installed under certificate list. Double click on that and view the details in Certificate tab.

Export that certificate , by extension *.crt' and save it local drive. FTP this to SAP server.

In JAVA Stack,

Thru Visual Admin > Dispatcher > Server 0 > Key storage >Run Time.

click on ; Ticket keystore' > SAPLogonTicketKeypair~cert

click on 'Export'. save tht certificate to SAP server

now, in the same window, click on 'Load' and upload that ABAP certificate.

Go back to ABAP stack

Strustsso2 > system pse > server name (double click)

click 'Import' and select that java certificate (FTP that java certificate to your local HD).

once this import is done, save and execute the TR sso2 and click execute.

Check everything is green, if yes, your java stack can communicate to your ABAP stack, with SSO.

Hope this helps.
