[dtp-connect-dev] ping failes
|
Dear all,
I have a problem with getting the Apache Derby example up and running.
I installed Apache Derby, I am not sure what I should do with the classpath. I created the DERBY_INSTALL environment variable.
I followed these steps:
- created the driver definition: it is a bit strange but the driver for the latest version of derby is not available, selected the available one.
I used the embedded JDBC driver
- I assigned the location where the derby.jar of my apache derby installation is located and the location where I am going to store my databases
- Then I created a connection profile. When I press the button test connection I get a message Ping failed
Here are the details:
java.sql.SQLException: Failed to create database 'C:\DataFiles\DerbyDatabases', see the next exception for details.
