Error while creating RFC destinations LCRSAPRFC & SAPSLDAPI

Hi All,

I want to activate ABAP Proxies in ECC 5.0. For that I am using following Blog:

/people/vijaya.kumari2/blog/2006/01/26/how-do-you-activate-abap-proxies

In this, while creating LCRSAPRFC & SAPSLDAPI destnations

I get following error 'Connection error:Error opening an RFC connection'.

I have given the same program ID in J2EE engine for JCo RFC Provider service of XI & the RFC destinations created in ECC 5.0 i.e. LCRSAPRFC & SAPSLDAPI.

Can anybody please guide me on this.

Thanks & Regards,

Chandravadan
