Re: Does Tomcat JDBC Connection Pool reset autocommit on closed connections?

The simplest way to be sure is to run a test with a pool size of 1. A quick look at the code (I might have missed something) suggests that if defaultAutoCommit is configured then it will be reset to that default value. Otherwise it will be unchanged from when the connection was returned to the pool.

The SQLite database (with sample data) should reside in the webapp itself,
maybe in a subdirectory

"javax.sql.DataSource" and use some
variable that would resolve the contextPath and that can be used in the "url"

There are samples that show how to use "${catalina.home}" as part of such a

"url"

Not currently, no. It would be a little tricky to implement given how
${...} replacement currently works.
