Changes in 2.0.0 (revision 264) compared to 1.1.5

-------------------------------------------------



The biggest and most important change is that the query template engine is been rebuild from the ground up to be a fully generic template engine. The query template engine has become an extension of this generic template engine.



Template file must have the following first line, starting in column 1:



<%@ template version="1.0" language="groovy" %>



The language attribute becomes optional when the TemplateLoader or QueryLoader is ocnfigured with a default language.

Supported script languages: groovy and javascript.

For javascript you need the rhino javascript implementation in the classpath.



A lot of improvements in the template compiler.



Generic templates:



	Template files need to have the .slt extension, for example: soap-result.xml.slt



Query templates:



	The QueryManager is renamed to QueryLoader.

	

	setPackage() is replaced with setTemplatePath()

		The path can now be:

			a folder in the classpath: "classpath:/solidstack/query/"

			a folder in the filesystem: "c:/folder/"

			a url: "file:/c:/folder/"



	Queries do not have to be bound to its parameters before execution. Parameters are supplied when executing.

	Template files need to have the .slt extension, for example: example-query.sql.slt

	

	Query.getPreparedSQL() is now public and returns a PreparedSQL object.

	

	Added directive: <%@ query language="SQL|JPQL|HQL" %>, default SQL

		The helps the Query to automatically determine if a native query or a normal query should be used.



	The HibernateSupport class is moved to the solidstack.query.hibernate package.

		Added methods:

			createQuery() which returns a org.hibernate.Query.

			executeUpdate() which calls org.hibernate.Query.executeUpdate() and returns the number of modified entities.

			list() which calls org.hibernate.Query.list() and returns a list of Hibernate entities.

			uniqueResult() which calls org.hibernate.Query.uniqueResult() and returns a single Hibernate entity or null.

		

	The JPASupport class is moved to the solidstack.query.jpa package.

		Added methods:

			getResultList() without the resultClass parameter. This one returns a list of Object[] or a list of objects depending on the number of values returned by the query.

			getSingleResult() without the resultClass parameter. This one returns an Object[] or an object depending on the number of values returned by the query.

			executeUpdate() which calls javax.persistence.Query.executeUpdate() and returns the number of modified entities.
