I'm getting the same error: "Lookup error: java.lang.SecurityException: Invalid username/password" when running eiter the cart or product samples. Any hints on what may be causing this? My config/application.xml is as follows: <?xml version="1.0"?> <!DOCTYPE data-sources PUBLIC "Orion data-sources" "http://www.orionserver.com/dtds/data-sources.dtd"> <data-sources> <!-- An example DataSource that uses an ordinary JDBC-driver to create the connections, to install; set the proper URL to the db, specify the db-driver name and unrem the below section. This creates all the needed kinds of data-sources, transactional, pooled and EJB-aware sources. --> <data-source name="Default data-source" class="com.evermind.sql.ConnectionDataSource" location="jdbc/DefaultDS" url="jdbc:HypersonicSQL:defaultdb" pooled-location="jdbc/DefaultPooledDS" xa-location="jdbc/xa/DefaultXADS" ejb-location="jdbc/DefaultEJBDS" connection-driver="org.hsql.jdbcDriver" username="sa" password="" /> </data-sources> Thanks, Micah Skilling.
