Exception thrown by tomcat originating in database errors do not specify the table(s) that cause the problem. For example:

Caused by: java.sql.BatchUpdateException: Duplicate entry ‘483384ff93ba497da101d07dcd2a1dde’ for key ‘PRIMARY’
at com.mysql.jdbc.PreparedStatement.executeBatchSerially(PreparedStatement.java:1666)
at com.mysql.jdbc.PreparedStatement.executeBatch(PreparedStatement.java:1082)

This makes finding the cause of the problem hard.

This is an error since such problems should be reported in term of the WebDSL program, not its implementation.
