Søren Berg Glasius has created a JDBC Providers project on BerliOS, which is something like SourceForge. We’re working on making it easier to run the providers on different databases. It already supported MySQL, and he’s adding Sybase. The idea is to put all the SQL code in an external properties file. There is still some code/DB dependencies, which I’m not sure how to get rid of, such as a dependence on the rough DB schema.
