Subject [jira] Commented: (DERBY-646) In-memory backend storage support
Date Sat, 14 Jul 2007 12:38:06 GMT

    [ https://issues.apache.org/jira/browse/DERBY-646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12512711

Dave Syer commented on DERBY-646:

I would like to test this storage strategy, but I don't know how to set it up.  I have compiled
the code against, and now I want to obtain a connection (ideally through a DataSource).
 This is what I tried


EmbeddedDataSource ds = new EmbeddedDataSource();
Connection connection = ds.getConnection();

It fails with 

java.sql.SQLException: Failed to start database 'memory:test', see the next exception for
	at org.apache.derby.impl.jdbc.SQLExceptionFactory.getSQLException(Unknown Source)
	at org.apache.derby.impl.jdbc.Util.newEmbedSQLException(Unknown Source)

There is no "next exception" in the stack trace.

I also tried:

DriverManager.registerDriver(new org.apache.derby.jdbc.EmbeddedDriver());
Connection connection = DriverManager.getConnection("jdbc:derby:memory:test")

which fails the same way.
