java - is javax.sql.DataSource thread safe?

Question

I am using the PostgreSQL 9.1 JDBC4 driver (postgresql-9.1-902.jdbc4.jar) in a Java EE application deployed in JBoss 7.

Can I assume that javax.sql.DataSource is thread-safe so that multiple threads can concurrently call the getConnection() method on it?

Answer 1

javax.sql.DataSource itself is an interface, so it is a specific to the implentation if it is thread-safe or not.

For the postgres sql driver, I recommend that you read Chapter 10. Using the Driver in a Multithreaded or a Servlet Environment from the official documentation:

The PostgreSQL JDBC driver is thread safe. [...]
