Hi,

I am working with Sun Solaris 9 Sparc,Sun-Blade-100.In my application,I need to monitor the UPS using Serial port.
When I am using JRE 1.4 in my application,I am able to monitor it but when I am upgrading the JRE version from 1.4 to JRE1.6. I am not able to monitor the UPS.It is showing the message

Can any1 tell me the reason and any idea to solve this issue ??
