JPA 2 Criteria API Tutorial

Sun, 07/10/2011 - 14:00 — mark

When JPA 2 was released in 2009 it included the new criteria API. The purpose of the API was to get away from using JQL strings , (JPA Query Language), in your code. Although JQL seems like a great way to leverage your existing SQL knowledge ,in the OO world it has a major drawback  namely;  there is no compile time checking of your query strings. The first time you find out about a spelling or syntactical error in your query string is at run time. This can be quiet a productivity drain with developers having to correct, compile and redeploy to  continue.

Maven, Jaxb-Schemagen Plugin POM.xml Setup and How to Generate XML Schemas for POJOs

Tue, 01/19/2010 - 06:02 — mark

When ever I need to use the JAXB maven plugin, it is always a task to configure the maven pom.xml file to get this tool to run, but usually an answer can be found pretty quickly so its just annoying. Most often I just use javaws and jaxb plugins to import and export web services, but recently I had to export XML schemas for some POJOs for a client, and this was a bit more of a challenge. It seems, from the google search results at least, that Java developers do not export XML schema definitons for POJO's that often.

Java - Parsing CSV Files How To

Sun, 05/17/2009 - 11:31 — mark

Parsing CSV files is one of those routine tasks that can end up taking an inordinate amount of time for a programmer to handle, especially once you discover the CSV file is not clean. Often CSV files come with extraneous headers and footers like, page numbers and distribution information. This is especially true if they are user generated, from spreadsheet applications like Open Office, or are effectively screen scraps of reports from some mainframe or AS400 reporting application.

JDBC connection to MS SQL 2005

Sat, 12/06/2008 - 16:43 — mark

I haven't had to work with MS SQL server since around 2003 but we recently took over a project that was running on MS SQL so I got to work with it again. It was quiet nice when MS took long to release new versions of its flagship database because it meant I didn't have to learn anything new for years. Sadly things have changed since then :) Although our client is running on MS SQL 2000 and that should have been a relief, except for the fact that, being a Linux shop, we don't have a copy of MS SQL 2000 and could only get the Express version of 2008 and 2005 from MS web site.
