Description

When looking for duplicate issue before raising, I found DERBY-540 which was closed out a while back - not sure if related

I've tried many versions of loading db from both classpath and jar
1) From Classpath
connection = DriverManager.getConnection("jdbc:derby:directory:/myDb");
connection = DriverManager.getConnection("jdbc:derby:directory:myDb");
connection = DriverManager.getConnection("jdbc:derby:/myDb");
connection = DriverManager.getConnection("jdbc:derby:mtDb");
2) From jar on classpath
connection = DriverManager.getConnection("jdbc:derby:myDb");
connection = DriverManager.getConnection("jdbc:derby:/myDb");
connection = DriverManager.getConnection("jdbc:derby:memory:myDb"); //load from classpath jar into memory
connection = DriverManager.getConnection("jdbc:derby:/myDb"); //load from classpath jar into memory
3) From non classpath jar - THESE WORK!!
connection = DriverManager.getConnection("jdbc:derby:jar:(C:/myDb.zip)myDb");
connection = DriverManager.getConnection("jdbc:derby:jar:(C:/myDb.zip)/myDb");

Unfortunately I couldn't get classpath based loading to work - I verified the zip was on the classpath and successfully loaded resources from it using:
Thread.currentThread().getContextClassLoader.getResourceAsStream(....)

Error stack trace is typically:

java.sql.SQLException: Database 'myDb' not found.
