SQLNonTransientConnectionException: No current connection, in my application while interacting with Derby database

Question

I implemented derby data base in my application to save my data,and I am getting this exception in retrieval of result set form select query in Derby database.

Answer 1

Found this via Google.

I had the same problem and found my answer in this sample application: http://db.apache.org/derby/docs/10.4/devguide/rdevcsecure26537.html

// force garbage collection to unload the EmbeddedDriver
// so Derby can be restarted
System.gc();

Works perfectly now.
