1. Tech Showcase
INSIGHT INTO DEVELOPMENT FRAMEWORKS
& TOOLS

2. Agenda
2
 Spring
 Hibernate
 Vaadin
 FishEye
 Bamboo
 Cobertura
 TWiki

3. Spring
3
LIGHTWEIGHT FRAMEWORK FOR
ENTERPRISE APPLICATIONS

4. Why Spring specifically?
4
 The most complete lightweight container
 A common abstraction layer for transaction management
 Integration with Toplink, Hibernate, JDO, and iBATIS
SQL Maps
 AOP functionality
 A flexible MVC web application framework

5. Hibernate
5
OBJECT RELATIONAL MAPPING (ORM)
FRAMEWORK

6. Why Hibernate? Isn’t JDBC enough?
6
 Exclude pure SQL data handling
 Transparent Persistence
 No interfaces or base classes needed for persistence.
 High Performance
 lazy initialization, Superior performance over JDBC
 Reliability and Scalability
 Clustered environment
 Comprehensive Query Facilities
 HQL & JPAQL support (preferred over SQL)

7. Vaadin
7
JAVA CODING -> JAVASCRIPT

8. Why I want to use Vaadin?
8
HTML, JavaScript & RPC
 Server side Java – Forget
 Extend or create own components
 Single JAR
 Browser compatibility
•Internet •Mozilla Firefox 3+ •Safari 3+ •Opera 10 •Google Chrome 4
Explorer 6+
 Supported application servers
•Apache Tomcat 4.1+ •BEA WebLogic 9.2+ •IBM WebSphere Application
Server 6.1+
•Jetty 5+ •Glassfish 2+

9. FishEye
9
A WEB SOURCE CODE CONTROL SOLUTION

10. Drawbacks in current source code control
10
 Current version control frameworks lack high quality
source code viewer.
 Going through deep directory trees takes time.
 Diffs with VI or Notepad takes time.
 Reports on who, when, what about code not possible.

11. What FishEye offers?
11
 Best side-by-side diff viewer for Subversion, Git,
Perforce, ClearCase or CVS.
 Fast navigation.
 Personalized dashboard that displays the activity related
to the projects, repositories, people, and source
 Email & RSS Feeds
 Reports to visualize the growth of the project

12. Bamboo
12
CONTINUOUS INTEGRATION SERVER

13. What is continuous integration?
13
 Iterative Development + Automated Testing
 Changes are delivered in small, rapid increments, instead of
a single delivery
 Every time a change is made, the system is built, and all
tests are run
 Keep the system working by keeping the build GREEN
 Fix BROKEN builds ASAP

14. More with Bamboo
14
 Statistics of the build
 Build times
 % of successful vs. failed builds
 Number of failing tests
 Time to fix a build failure
 Historical summary helps identify the problem.
 E.g. How this test failed in the past? , How it was
fixed?
 Integration with FishEye

15. Cobertura
15
FREE JAVA TEST COVERAGE TOOL

16. Cobertura
16
 Can be executed from ant or from the command line.
 Can generate reports in HTML or XML.
 Shows the percentage of lines and branches covered
for each class, each package, and for the overall
project.
 Can sort HTML results by class name, percent of lines
covered, percent of branches covered, etc. And can sort
in ascending or descending order.

17. TWiki
17
WEB BASED OPEN SOURCE COLLABORATION
SYSTEM

18. What is TWiki used for?
18
 Online collaboration platform.
 Project tracking.
 Document management system
 Organize and share knowledge
