Hello all:
I am experiencing strange jdbc errors. I am running tomcat 3.2.2 on win2k. I
store the request parameters from the browser into a hastable. Then I pass
the hashtable and response object to a new instance of a class. The method
in the class then queries the database if a particular user name already
exists. I tried using prepared statement as well as Statement but as soon as
I give a call to database_connection.close(), I get an SQL Exception..The
stack trac is as follows
Closing database connection....

This subsequently causes tomcat to crash occasianally....it also produces a
log file..
Can someone explain why this is happening? I am using Microsoft Access 2000
Database
Thanks
