JCo Connection - (102) JCO_ERROR_COMMUNICATION

1397 Views

Hi gurus 😊

I have been struggling with a development in java :). I got a new brand laptop with i7 processor. So I change my development from my MACOS system. I had to find the appropiate driver for Windows 7 and this processor. ( I've never knew if the x64 worked in my laptop )

the reason, its I am working with the 32 bits driver. I realized that probably the other driver worked. the problem here is the system number of the server which I am trying to connect to.

Does anybody know why, if I connect to a

HOST : xxx.xxx.xxx.xxx - SYSNR : 07 - CLIENT: 001

. My application works flawlessly, But when I am trying to connect to

HOST : xxx.xxx.xxx.xxx - SYSNR : 24 - CLIENT: 800

it cant even connect and shows the next error message. (Remind that the same application connected to a different system number works just perfectly )

Any help would be really appreaciated 😊 BTW if somebody know which one is the appropiate i7 driver 😊 My laptop will be really glad 😊 I know she is feeling jealous of MACKY 😊
