Is anyone here using it via a Singleton pattern? I'm trying to figure out
the best way to use this...

Currently, we have an object that gets a database connection (with no
pooling), and I'm trying to snap DbConnectionPool in with it. I have two
static variables
within the object now, one for db connection pool reference (that only gets
initialized once) and a variable for a connection (public). In the
constructor of this object, I check to see if connection is null or closed.
If it is, I get another connection from dbpool.

When I do stress testing with Apache JMeter, I'm getting lots of errors like
this:

java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]Connection is busy
with results for another hstmt


Can you see holes in my logic? Should I just create a method that doles out
a connection, and another that calls freeConnection after I'm done with it?
The only reason I don't do this now is because all the changes I'll have to
make to accomodate this.


TIA,
