I am running Netbeans 8.02 on Windows 10 Pro 64-bit, and the other day I discovered that I can't access the 'sample' Derby database any longer. I get the following error:
Unable to connect. Cannot establish a connection to jdbc:derby://localhost:1527/sample using org.apache.derby.jdbc.ClientDriver (DERBY SQL error: ERRORCODE: 40000, SQLSTATE:XJ040, SQLERRMC: Failed to start database 'sample' with class loader sun.misc.Launcher$AppClassLoader@60e53b93, see the next exception for details.::SQLSTATE:XSLAM).
Apache Derby is running and it otherwise seems in good working order. The only things using the 'sample' database are the apps from this completed tutorial: Enterprise application tutorial
That's the only thing that I can think of that might have caused this error. Thanks in advance.
Thanks for replying. Here's what I found in the logs:
