TOTD #93 showed how to get started with Java EE 6 using NetBeans 6.8 M1 and GlassFish v3 by building a simple Servlet 3.0 + JPA 2.0 web application. TOTD #94 built upon it by using Java Server Faces 2 instead of Servlet 3.0 for displaying the results. However we are still using a POJO for all the database interactions. This works fine if we are only reading values from the database but that's not how a typical web application behaves. The web application would typically perform all CRUD operations. More typically they like to perform one or more CRUD …

TOTD #93 showed how to get started with Java EE 6 using NetBeans 6.8 M1 and GlassFish v3 by building a simple Servlet 3.0 + JPA 2.0 web application. JPA 2.0 + Eclipselink was used for the database connectivity and Servlet 3.0 was used for displaying the results to the user. The sample demonstrated how the two technologies can be mixed to create a simple web application. But Servlets are meant for server-side processing rather than displaying the results to end user. JavaServer Faces 2 (another new specification in Java EE 6) is designed to fulfill that purpose.

NetBeans 6.8 M1 introduces support for creating Java EE 6 applications ... cool!

This Tip Of The Day (TOTD) shows how to create a simple web application using JPA 2.0 and Servlet 3.0 and deploy on GlassFish v3 latest promoted build (58 as of this writing). If you can work with the one week older build then NetBeans 6.8 M1 comes pre-bundled with 57. The example below should work fine on that as well.

1. Create the database, table, and populate some data into it as shown below:
   
   

   ~/tools/glassfish/v3/58/glassfishv3/bin >sudo mysql --user root …

Gearman is an open source generic framework for distributed processing. At OSCON 2009 I attended the Gearman: Build Your Own Distributed Platform in 3 Hours tutorial.

While it’s very easy to install Gearman, and follow the first example, if you missed the all important additional PHP steps listed on just one slide you may be left with the “‘Class ‘GearmanClient’ not found” error.

The following are detailed instructions for the installation and configuration of Gearman and PHP on Ubuntu 9.04 Jaunty.

Add the Drizzle PPA to get pre-packaged versions of Gearman.

cp /etc/apt/sources.list /etc/apt/sources.list.orig
echo "deb http://ppa.launchpad.net/drizzle-developers/ppa/ubuntu intrepid main
deb-src http://ppa.launchpad.net/drizzle-developers/ppa/ubuntu intrepid main" …

Sysbench is a open source product that enables you to perform various system benchmarks including databases. Drizzles performs regression testing of every trunk revision with a branched version of sysbench within Drizzle Automation.

A pending branch https://code.launchpad.net/~elambert/sysbench/trunk_drizzle_merge by Eric Lambert now enables side by side testing with MySQL and Drizzle. On a system running MySQL and Drizzle I was able install this sysbench branch with the following commands.

cd bzr
bzr branch lp:~elambert/sysbench/trunk_drizzle_merge
cd trunk_drizzle_merge/
./autogen.sh
./configure
make
sudo make install

Running the default lua tests supplied required me to ensure …

If your compiling a product that includes a dependency of MySQL, you can easily get the error

configure: error: mysql_config executable not found

I generally don’t see this problem, because I use MySQL binary tar files, however if you use MySQL packages, such as Ubuntu, you can easily miss the required dependency.

My currently installed MySQL packages on this Ubuntu machine are:
