Eclipse - connection to Gateway demo system not working

[Former Member]

Hi,

I am configuring connection to Gateway demo system : sapes1.sapdevcenter.com @ port 443.

I am getting network connection error.

Parameters in Eclipse -> WIndows->Preferences->

Server host: sapes1.sapdevcenter.com

Port: 443

username:

password:

No HTTPS selected.

I am pasting Eclipse log file logs for ref:

Selecting HTTPS checkbox in Eclipse-connection parameters did the trick

Thanks Friends.

Hi Divyesh,

                  Please check if the port is opened at the time you are trying to connect to the system.

You can do that by going to cmd ->telnet <server-name> <port-no>

If the port is opened then you might have to make an entry of your server's name and port number in host file located in System32 in case you are using windows.

Telnet>open sapes1.sapdevcenter.com:443 --->not working.

Can you tell me which URL, I should use in Eclipse- connection parameters?

I am using below for Netweaver gateway demo system:

Server host: sapes1.sapdevcenter.com

Port: 443

Divyesh,

               The connection parameters can be got from your BASIS team

These are the parameters you need to  establish connection with gateway

when you use

telnet[space]<server-name>[space]<port-no>

If you get a blank screen it means the port is opened, else you have to open the port.

try pinging your server host-name and  check if your system is connected to it.

When all the above things are successful...

while deploying you may have to add an exception in the proxy settings of your browser.

Regards,

Prathik
