eBook - Java Application Development on Linux

"Java™ Application Development on Linux® - Free 599 Page eBook"

Linux is the fastest-growing Java development platform because it saves money and time by serving as a platform for both development and deployment. But developers face significant platform-specific challenges when managing and deploying Java applications in a controlled production environment.

Written for Java and Linux developers alike, Java™ Application Development on Linux® is the hands-on guide to the full Java application development lifecycle on Linux.

Determined to spare other developers hours of trial and error, Albing and Schwarz demonstrate the platform, tools, and application development by showing realistic, easy-to-follow examples. After a simple command-line application introduces basic tools, this program leads readers through business-logic object analysis, database design, Java servlet UIs, Java Server Pages (JSP) UIs, Swing GUIs, and Standard Widget Toolkit (SWT) GUIs. Scaling up to the enterprise level provides the opportunity to use both the JBoss Application Server and the Apache Geronimo Application Servers, and Enterprise JavaBeans (EJB).

Readers learn how to:
 * Use development tools available on Linux, such as the GNU Compiler for Java (gcj), Ant, the NetBeans IDE, IBM's Eclipse Java IDE, JUnit, and SunONE Studio
 * Develop business logic layers using Java DataBase Connectivity (JDBC)
 * Add a Web interface using servlets and JSPs
 * Add a GUI using Sun's Abstract Window Toolkit (AWT) and IBM's SWT
 * Deploy EJBs in Linux

The authors conclude by demonstrating how a hierarchy of budgets can be created, tracked, and shared with Concurrent Versions System (CVS). Java™ Application Development on Linux® can propel you from a standing start to the full-speed development and deployment of Java applications on Linux.

White Paper - There's an App for That, But is it Secure?

"There's an App for That, But is it Secure?"

This Tech Dossier will outline proven best practices to mitigate risk and embrace mobility without trepidation.

Security has eroded over the past decade as companies strive to create applications for multiple platforms by farming design and development out to subcontractors. This trend has strained the processes and governance put in place to ensure application security.

Display Dialog boxes from shell scripts - Whiptail

whiptail is a lightweight replacement for dialog, to provide dialog boxes for shell scripts. It is built on the newt windowing library rather than the ncurses library, allowing it to be smaller in embedded environments such as installers, rescue disks, etc.

Currently, these types of dialog boxes are implemented:
yes/no box, menu box, input box, message box, text box, info box, checklist  box,  radiolist box gauge box, and password box.

whiptail is designed to be drop-in compatible with dialog, but has less features: some dialog boxes are not implemented, such as tailbox, timebox, calendarbox, etc.

Whiptail Installation:
Open the terminal and type following command to install whiptail:

sudo apt-get install whiptail
