Thanks for your help everyone ..... after some number of hours of work yesterday, I managed to get everything changed over, and I'm NOT using the SingleThreadModel. I inherited part of the code, and wrote most of the rest .... a couple of perl scripts was able to help significantly.
Long and the short, was we were trying to get away with an OOP design, in which all of our servlets derived from a single class (which in turn, implements HttpServlet), so that our forward(), logging, and erroring methods could be easily implemented. In doing so, you were all correct, we were over-writing our own variables. On Wednesday I upgraded to the latest DBCP and Commons Pool, as well as the latest JDBC driver for our vendor, reducing the number of those errors from an enormous 760 to 220. Today, thus far, we've had a total of 10 errors, only two of which were related to that same problem, and probably are from me missing something in the code. Thanks for your help in this mess .... --Anthony On Thu, 2003-12-11 at 15:00, Antonio Fiol BonnÃn wrote: > >So ..... what your telling me, is that it's a concurrency problem > >created by having "object attributes"?
