Hi alll,

please help us in resolving the Error with Jco ........

Even though we have given correct username and Password we are getting Error.

Error is as Below:

RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed,

Connect_PM GWHOST=http://ciber:8000/sap/bc/gui/sap/its/webgui, GWSERV=sapgw00, ASHOST=http://ciber:8000/sap/bc/gui/sap/its/webgui, SYSNR=00

LOCATION CPIC (TCP/IP) on local host

ERROR hostname 'http://ciber:8000/sap/bc/gui/sap/its/webgui' unknown

Code related to the above Error is ................

JCO.Pool Pool = JCO.getClientPoolManager().getPool(pool_Name);

JCO.Client mconnection;

if(Pool == null)

{

System.out.println("1");

JCO.addClientPool(pool_Name,10,"100","USER","password","EN","http://ciber:8000/sap/bc/gui/sap/its/webgui","00");

System.out.println("2");

mconnection = JCO.getClient(pool_Name);

System.out.println("3");

System.out.println(mconnection.getAttributes());

}

Waiting for the reply

Thanks and Regards,

hi preethi,

from the logs, it says that the SAP gateway is failing.

it seems that you are specifying a wrong host name.

"http://ciber:8000/sap/bc/gui/sap/its/webgui"

>JCO.addClientPool(pool_Name,10,"100","USER","password","EN",

>"<b>http://ciber:8000/sap/bc/gui/sap/its/webgui</b>","00");

try changing this to your ASHostName.

hello preethi,

had you tried specifying the host name of the SAP

application server rather the URL "http://ciber:8000/sap/bc/gui/sap/its/webgui"?

hello preethi,

check on the program SAPLZLBSGROUP; it might have some

syntax related errors as described by the message.

try looking at ST22 dumps or your JCO trace files.

you will be able to get some hints what went wrong.
