SAP NW Gateway - Network Connection Error

[rajkishor10]

Hi All,

I am facing an issue with the SAP Netweaver GW connectivity via Eclipse Juno 2.0

I have the SAP NW Gateway components and installed and configured on SAP Netweaver 7.0 Ehp 2 (CRM System).

When I create a new connection it errors with the message 'Network Connection Error' .

I have tried creating a connection through Eclipse to the SAP Demo Gateway server it's showing error "Network Connection Error".

This is the Log File:

Message:

Network connection error

Hi Raj,

You mentioned  "tried creating a connection through Eclipse to the SAP Demo Gateway server", but the host/ip-address/http-port from your screendump didn't reflect this.

Also, did you activate NW Gateway in SPRO on your CRM system?

I hope this will help you.

Regards,

Andre
