The IPCC Express agent desktop must access the jtapi.tar file that is located on the IPCC Express server when the application starts:
\\Program Files\Cisco\Desktop_Config\Desktop\Agentins\JTAPI\jtapi.jarIf the agent desktop detects there is a mismatch between its jtapi.tar version and the jtapi.jar version on the Cisco IPCC Express server, the agent desktop must copy jtapi.jar on the Cisco IPCC server to itself. The problem described in this document occurs when the agent desktop fails to perform this function, and the jtapi.jar version on the agent desktop needs to be manually updated.
To manually update the file, copy the jtapi.jar file from the IPCC Express server to the agent desktop JTAPI client folder:
\\Program Files\Cisco\Desktop\bin\CiscoJTAPIClient\Lib\jtapi.jar
