Thread: RE: Compiling JDBC Driver - impossible!
If anyone wants to submit to me successfully built Postgres JAR files (1.1
and 1.2), I'm happy to create a site where people can download them... I
guess it would be useful to have all manner of JARS (RC-x) available too.
Let me know or just submit successfully built JAR's and I'll send a message
to the list when the site is ready. I know I'd find this handy sometimes.
Cheers,
Joe

I agree, this is an excellent idea. A repository of JDBC driver JARs for each different Postgres release - good thinking.
