Re: Unable to make a connention through jdbc

Hi, Dave,

I already tried all the three drivers under the
8.0/jdbc directry and get the same error message. Can
you provide a URL of the documentation in regarding of
the difference among the three drivers.

I will change the server character configuration to
overcome this problem. I had a typo in my email of the
IP address.

Thanks a lot for your promptly helps.
