    Trying to connect an executable JAR file to a database on a server but I keep getting error java.sql.SQLException: No suitable driver found?

    Stack Overflow | 12 months ago | Badddams
    java.sql.SQLException: No suitable driver found for jdbc:postgresql://localhost/projectdb From research into previous questions I understand that I may need to add or SET the classpath for the JDBC jar file so that when the JAR file executes it knows where to find it. However I don't know how to do this and other answers seem unclear. I'm using Postgresql and I'm trying to implement this on my server using Ubuntu 14.04. This works fine on my local machine but that's because the JDBC is included as a referenced library. Here is a snippet of code from the log. java.sql.SQLException: No suitable driver found for jdbc:postgresql://localhost/projectdb
