If you have duplicate entries in a resultset of a hibernate query, then this could be caused by a eager fetchmode. A result is to add a ResulTransformer to your query.
Example:
Criteria criteria = getSession().createCriteria(Order.class); criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

input {
outline: 0 none;

I needed some simple functions for writing integegration tests with DbUnit.
Functions like:
NOW()
addDays(NOW(),1)

addDays(baseDate, days), addHours(baseDate, hours),
addMinutes(baseDate, minutes) and addSeconds(baseDate, seconds)
Example 1:
<table […]

But there are two workarounds:
Patching the actionmailer staticly
This workaround is metioned in the […]
