Обсуждение: Windows port installer
Hi, I'm currently working on the installer for the binary distribution of the Win32 port of PostgreSQL. We are already including psqlODBC and Npgsql, and would like to include the JDBC driver as well. Knowing nothing about JDBC I'm at a bit of a loss however and would appreciate some guidance on what files to install, and where, as well as any changes to the environment or registry etc. that may be required. TIA, Regards, Dave [Oh, and please CC me as I'm not on the JDBC list].

Here's an opinion from someone who's not really a JDBC driver developer at all. There's not really a location to install JDBC drivers onto an operating system. They are not native libraries, and are typically packaged with applications. The closest thing you could do to an installation would be to locate JVM install directories via "HKEY_LOCAL_MACHINE/SOFTWARE/JavaSoft/Java Runtime Environment/*/JavaHome", and drop the JAR file into lib/ext relative to that directory; but frankly I'd probably resent your doing so and certainly wouldn't find it very useful. If you need to give lip service to including JDBC drivers for political reasons, then the best approach is probably to just leave the JDBC driver JAR file somewhere, and provide documentation on how to find it. -- www.designacourse.com The Easiest Way to Train Anyone...

Hmm, probably not the best option as you suggest. I wasn't sure if there was something like .NET's Global Assembly Cache into which such files should be installed. > If you need to give lip service to including JDBC drivers for > political reasons, then the best approach is probably to just > leave the JDBC driver JAR file somewhere, and provide > documentation on how to find it. That's certainly easy enough - by default it would probably end up in C:\Program Files\PostgreSQL\7.5\JDBC\. Are there any html docs etc. that should/could be included? Thanks, Dave.

This URL has about a month old version: http://www.ejurka.com/pgsql/docs/cvs/ For release we will have something easily downloadable, probably a .tar.gz. Do you want/need something now to get the process down? Kris Jurka

I'm no .NET expert, but I think the JRE extensions directory is a lot like the GAC. It's just not used in the same ways because it's more difficult to find it from installation kits, and because of historical issues. -- www.designacourse.com The Easiest Way to Train Anyone...

My suggestion would be to put it wherever you are putting the postgresql libraries, then tell the user how to set the CLASSPATH.

No, Idon't need one as such, just wondered if there was a simple HTML starter guide or similar that could be included (there is one for Npgsql). Regards, Dave.

OK, I'll just leave the jar files under the main installation directory for now then. Thanks, Dave.

Hi Dave, I'm trying to keep each component of the installation in a separate directory for simplicity/cleanliness/organisation etc. so unless there's a specific need to put them in \lib, I'd rather avoid doing so. I'll certainly do something about the classpath though - we should be able to automate that - thanks. Regards, Dave.
Dave, there's no reason to put it there, however as someone pointed out putting it in jre/ext will be a problem for Tomcat.
