Hi Nicolas: This is a working example of the truncation configuration in portal-mysql-ds.xml: <?xml version="1.0" encoding="UTF-8"?> <local-tx-datasource> <jndi-name>PortalDS</jndi-name> <connection-url>jdbc:mysql://localhost:3306/your_database_name?useServerPrepStmts=false&amp;jdbcCompliantTruncation=false</connection-url> <driver-class>org.gjt.mm.mysql.Driver</driver-class> <user-name>your_portal_database_user_name</user-name> your_portal_database_user_password </local-tx-datasource> Also, have you granted permissions to your_portal_database_user_name on the portal database you created in MySQL? Sorry if this seems simplistic but this configuration works very well so I'm wondering if you have typographic errors somewhere.
