The actualy Version is Infor Web UI 10.16 - build MA0029
i think if you plane a update you should use this Version.
but also the tomcat Version and JRE Bundle are changing...
you install this Version on another port. sho you can test it, prarallel to the live webui.
for example: http://infor01:8312/webui
live webui and http://infor01:9312/webui
if the Errors are solved you can Switch all users to port 9312 or update the live Version.
if you have any questions - feel free to contact me.
