I vaguely remember having a similar sounding problem with the DB2 for as/400 oledb driver when trying to set up a linked server from sql 2005 to the as/400.

There is no way to find out the source of an exception *after* it's caught, unless you include that information when it is thrown. By the time you catch the exception, the stack is already unwound, and there's no way to reconstruct the stack's previous state.

Maven helps quite a lot with this problem when I'm coding java. We commit the pom.xml to the scs and the maven repository contains all our dependencies.

One possibility is Hudson. It's written in Java, but there's integration with Python projects:

AFAIK, there's no ready-made library to do this for you, but producing a tool capable of translating from CSV to XML should only require you to write a crude CSV parser and hook up JDOM (or your XML Java library of choice) with some glue code. |
