Embedded Derby DB examples Add comment to Wiki View in Wiki Edit Wiki page Printable Version

Be sure that derby.jar is either:

  • in the groovy lib folder
  • explicitly set in the classpath (ie. set CLASSPATH=%CLASSPATH%;/path/to/derby.jar)
  • loaded at runtime (ie. this.class.classLoader.rootLoader.addURL(new URL("file:derby.jar")) )

If you are using JDK 1.5 or greater, a LinkageError will occur. Removing the mx4j-3.0.2.jar library from %GROOVY_HOME%\lib will make it work again, but a better solution would be preferable.

Look at http://jira.codehaus.org/browse/GROOVY-2303 for further information, or ask on the user@groovy.codehaus.org.

This will create derby.log and derbyDB folder in the folder where the script is.

If something goes wrong, simply remove derbyDB folder, and everything will be clean for next run.
