Connected remotely to the user to continue to check and fix the error encountered when printing barcodes for casepack PO. Installed the application to the user's PC, as the existing application is not installed, after installing tested the application, and as per testing, the same error is encountered, and while testing, an error is encountered in searching, the connection time out. check the existing barcode if the same error is encountered, as per checking, it does, and the same error is encountered, then after checking the installed application it now extracts the data from JDA meaning, the search work and connects to JDA successfully, there are no changes on this yet. Modified the application to add a variable in the application to see where the exact error is encountered, when the error in search is encountered, the message prompt "connection time out - cannot connect to JDA", is added before the connection is to be opened, meaning the error is on the connection into JDA, though check the ping, there are RTO and it is frequent and while the error in search is encountered there is no RTO in ping. Checked the application again, and as per checking, the error is encountered in printing, still checked for the cause of the error and see why it is having an error on this while on my PC and Arvin's PC this is working and this is working as well before the anti-virus is installed. We request for a restore before the AV is installed and check the barcode again, as per checking, the same error is encountered. The checking and fixing will continue tomorrow.
