The following code just never
// Load class "org.sqlite.JDBC" Class.forName("org.sqlite.JDBC");
// Establish connection to database named "treehouse.db" try(Connection c = DriverManager.getConnection("jdbc:sqlite:treehouse.db")) {
} catch(SQLException ex) {
}
// Load class "org.sqlite.JDBC"
Class.forName("org.sqlite.JDBC");
// Establish connection to database named "treehouse.db"
try(Connection c = DriverManager.getConnection("jdbc:sqlite:treehouse.db")) {
} catch(SQLException ex) {
}

The problem is the Treehouse error that states: "Oh no! We didn't hear from the challenge service in a timely fashion!".
I've reported it to their support team. But in case anyone else comes by, the construct is valid and I'll report back here what they reply with.

try {
// Your code here - i.e. what you want to try to do
} catch (Exception exc) {
// Error handling code
}
I understand the way that the challenge has been set out makes it seem like you put your code within the try ( here), but try keyword should be followed by an opening curly brace.

1,141 PointsThis construct is a "try with resources", the issue seems to be the actual connection is timing out and I'm receiving an error about the server process not executing in time.

8,181 PointsFair enough, but it did work for me when I put your code inside the try block.
