Move init() method to top of class for clarity (See #137)
Update spelling of applicationContextTest.xml (case sensitive) (See #137)
Set hibernate.show_sql to false in applicationContext.xml (See #137)
Set dataTypeFactory to HsqldbDataTypeFactory in ApplicationContext.xml (See #137)

Without specifying the dataTypeFactory, there were a series of warnings
when running the test dbunit setup:

[main] WARN org.dbunit.dataset.AbstractTableMetaData - Potential
problem found: The configured data type factory 'class
org.dbunit.dataset.datatype.DefaultDataTypeFactory' might cause
problems with the current database 'HSQL Database Engine' (e.g. some
datatypes may not be supported properly). In rare cases you might see
this message because the list of supported database products is
incomplete (list=[derby]). If so please request a java-class update via
the forums.If you are using your own IDataTypeFactory extending
DefaultDataTypeFactory, ensure that you override getValidDbProducts()
to specify the supported database products.
