Astrient 101: Java, Tomcat, Linux
Wednesday October 21, 2009 10:00 PM

HostJ2ME.com and WorldDeveloper.org (CliqCafe hosted) are Java web applications running on Tomcat 6 on Centos. Specifically:

[root@HostJ2ME ~]$ cat /proc/version

Linux version 2.6.24-19-xen (buildd@king) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Sat Jul 12 00:15:59 UTC 2008

[root@HostJ2ME ~]$ java -version

java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)

This environment has been stable for years, and we often operate our servers for hundreds of days at a time before rebooting or restarting services. Using Slicehost.com, we are able to clone or backup servers with little effort. Here are the issues that we considered when choosing the technologies for the two aforementioned applications.

  • Java is stable, has many free and open source libraries and components, has a robust API, and is very easy to use.
  • Linux offers great stability, a small footprint, a familiar command line with great tools for managing processes, resources and files, and has a low cost of maintaining with many hosting options.
  • Tomcat is free, mature, and provides all of the functionality we need. Although we are essentially a Java shop, we do not see the need for complex application frameworks or a soup of XML files.

    H2 Database
    Wednesday October 21, 2009 9:30 PM

    At Astrient we use MySQL for all of our web applications. As an alternative,
    we have found most developers to consider the PostgreSQL database. Which is why I was very surprised when I stumbled upon the H2 database. From the details presented on the H2 website, the database engine not only performs well but packs a comprehensive set of features and can be embedded in applications. I would recommend anyone looking for an alternative to MySQL and PostgreSQL to visit:
