In addition to above :-

1. Create a TCP/Ip connection from the abap system to portal with the program id hostname_portal_sid.

2. Maintain/check used Jco destinations (WebDynpro Content Administrator ‘Maintain Jco Destinations’).

3. Test the connection between them.

4.Create an entry in the table rspor_t_portal using sm30 and enter the details of the portal like http://hostname:50000.

5. Create a system in the portal and specify all the parameters as hostname, msg server.

Himanshu

Hi Santosh,

If I understand correctly that you want to connect ABAP system (say ECC) as back-end with JAVA portal (say EP), then the configuration can be established through JCO RFC connectors. JCO RFC can be created through netweaver administrator link of EP (http://<FQDN of EP server>:<port>/nwa) .

After creating JCO RFC connection, mention the program ID in ECC system during creation of TCP/IP RFC .

This would create a connection between EP & ECC . Now in order to fetch data from ABAP system in EP, you also need to create JCO connections, which I have elaborated in my blog http://scn.sap.com/community/netweaver-administrator/blog/2013/07/30/jco-connections-required-for-ess-mss-configuration .

Please let me know if any issue.

Regards,

Nilutpal.

Hello

An RFC from the ABAP system to the Java system - Tx SM59

A Jco RFC from the Java system to the ABAP system - NWA for newer releases / Visual Admin for old releases.

The JCo RFC should be started in the Java stack.

See an example here:

Hi Santhosh,

Yes ! its correct that all the above mentioned method will connect your JAVA portal to ABAP backend.

But you have to do many lot more steps with respect your use case , ie. For example if you want to connect BI poral to ABAP BW system or EP to ABAP ECC, then there is separate guide for configurations.

So first explain your Use case, then chose the correct reply

Hi KK,

Thanks for reply. As suggested by you, i can create RFC Connection between Portal and Abap. You asked me the configuration, We need to connect the Portal (only contains java ) to ABAP Server (ECC 6.0 EHP4) . Can you please tell me the required configuration (apart from RFC) need to do. The requirement is to connecting both and fetch the data from ABAP

Thanks

Hi Dipak,

As per my understanding you have you already done the SSO(Single Sign On) Configuration and JCO RFC Configuration in your Portal System?

Please let us know if you have done any of those configuration ? Also what is the Portal Netweaver Release Version and the ABAP Netweaver Version you are using ?

In order to access the ABAP backend data via Portal Interface you have to perform the above activities.

Thanks and Regards
