Hi,

I just start to work on JCo and when i tried to eastablish a connection, i recieved error report as below:

Start to connect

Caught an exception:

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed

my client is set as followed:

client = JCO.createClient( "001", // SAP client

<id>, // userid

<password>, // password

"EN", // language

"NSPAD421", // host name

"10" ); // system number

Does anyone has any idea of this?

Thanks.

Hi Li,

May be its the problem with the gateway port.Ask your basis guys to open the port for the gateway sapgw10 .The port number for this gateway can be found in hosts file under etc folder.

Hi,

U need to give the MSGSERVERPort no in ServerSystemwindowssystem32drivershosts--services.

Add the following

MSGSERV tcp/3601.

and in the host file also add the following

192.10.100.10 EPhostname

It is not reaching to the R/3 system.

Thanks,

Lohi.

I have config the files you mentioned already, however the server still can not reached by the JCo. Did i forget something still?

Maybe there is a problem with a firewall. Try to ping the server or to reach it via "telnet" on that mentioned port.

Hi, Thanks, there is no problem for me to ping the server but the jco still can not reach it.
