[jira] Commented: (OPENJPA-1091) ReverseMappingTool fails for
openjpa-examples/reversemapping sample
[ https://issues.apache.org/jira/browse/OPENJPA-1091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12784482#action_12784482 ]
David M. Karr commented on OPENJPA-1091:
----------------------------------------
Concerning the last comment, I believe that's the problem that I've noticed. I noticed the following in the log when I tried to run it on WinXP.
<openjpa-1.2.1-r752877:753278 fatal user error> org.apache.openjpa.util.UserException: A connection could not be obtained for driver class "org.apache.derby.jdbc.EmbeddedDriver" and URL "jdbc:derby:c:\frameworks\apache-openjpa-1.2.1\examples\reversemapping/reversemapping-database;create=true". You may have specified an invalid URL.

Caused by: java.sql.SQLException: Failed to start database 'c:\frameworks\apache-openjpa-1.2.1\examples\reversemapping/reversemapping-database', see the next exception for details.
