JCo: Fatal error - GUI cannot be reached

[Former Member]

Hello,

when trying to make a RFC which calls a transaction in batch mode i get the following error "Fatal error - GUI cannot be reached", even if SAPGui = 1. The call is only successfull when activating the debug mode.

Used versions see below (installed SAP Gui = 6.40).

Is there a newer JCo Library available in the Marketplace, and if yes where. I couldn't find one.

Thanks for any help in advance.

Solved the problem. It seems that pooled JCO Connection have problems with the GUI. Doing the same with a non pooled connection works correctliy
