Starting this year, we are going to host a series of articles focused on the Hibernate community.
We are going to share blog posts, forum and StackOverflow questions, that are especially relevant to our users.
For my first post, I’d like to share the experience of running the in.relation.to blog on my Windows machine.
All the blog content is available on GitHub, and you can practically run the whole site on your local environment.
The Hibernate blog is built with awestruct from Asciidoctor files, and getting all the Ruby gems in place is definite not a walk in the park.
To make matters worse, I’m running a Windows machine and all these Ruby gems are tightly coupled to Linux libraries, as I discovered after several failed attempts with the 64 bits Ruby 2.2.4 or the 32 bits Ruby 1.9.3.
Hibernate has moved to Git (hosted on GitHub) for source control. That has been well documented. I wanted describe the approach Hibernate takes to branching, versioning and releasing as it is something that has come up a number of times, even prior to the move to Git.
Yyou probably don't know it yet but Hibernate Core and Hibernate Validator source code is now on Git and Hibernate Search and co will likely follow very soon. There are various reasons for the move but to summarize it, life was not bad under SVN but it's really great under Git.
In Hibernate there is a particular branch of logic where we need to parse and validate an org.xml.sax.InputSource that might represent either a Hibernate mapping (hbm.xml) file, a 1.0-compliant orm.xml file or a 2.0-compliant orm.xml file. Now currently Hibernate mapping files are defined by a DTD and both versions of the orm.xml files by an XSD. Currently the code builds a SAXReader with DTD and Schema validation enabled and tries to read in the source. It first maps Schema validation to the 2.0 version of the XSD; if an error occurs it then tries re-parsing mapping Schema validation to 1.0 version of the XSD.
The JPA 2 metamodel is the cornerstone of type-safe criteria queries in JPA 2. The generated classes allow you to refer to entity properties using static field references, instead of strings. (A metamodel class is the fully-qualified class name of the entity class it matches followed by an underscore (_)).
The goal of this blog post is to walk you through an Java EE 6 application from a simple, static
web page until we have a full blown stack that consist of the stuff in the list below. I'm calling this
stack Summer because after a long, hard winter Spring may be nice but boy, wait until Summer kicks in ;-)
