Updating database from Servlet

I have thsi vague problem.
I made a simple phone book whick queries number according to name. It worked until I wanted to add counter to it.
When ever I click it also should update a Counter table in a database. I made a class for the updation process.
Its called UpdatePhoneBookCounter(Connection con).
First I used it from command line. I passed a connection from another test and also passed a date-string(new Date().toString()) so that it updates the table with date, month, year, day etc.
It works on command line.
But same creation of pdate class passing a connection has spoilt my basic phonebook too.
Is this because I am using the same connection for getting the phonenumber from 1st table and then again using it for updation??? ( I get the connection from another class Oracle Connection which is surely working)
Please help.

I forgot to give the URl.
The counter applet works with already existing data.
The update doesnot work.

Hello rk t,
First of all same connection can be used for more than one queries so you can count out that reason for the error. Secondly I tried to reach the link you have given but in vain it is not working. It gives me misspelled URL exception.
