Java Enterprise Development

Java application development best practices for "best fit" Java solutions

With over a decade of Java enterprise application development successes under our belt, we have evolved a set of best practices that are deployed across all development projects. Some fundamentals of these best practices include:

• Understanding the core requirements
• Define high level design using technologies/framework to be used in the development
• Identify the core modules and key risk areas
• Identify re-usable components at an early stage
• Optimize development with proven techniques such as automating the build and deployment process using tools like Apache Ant or Hudson

Better application quality through a test driven development approach

We follow a test driven development approach in Java application development for better code quality and lower application lifecycle maintenance costs. Salient features of our test driven development methodology include:

• Write as many unit tests as possible to perform code level testing using frameworks like JUnit
• Set the validation rules for each and every part of the application (screen-by-screen)
• Automate the unit test scripts by integrating with the build scripts and generate test reports
• Try to minimize mocking of objects while unit testing

Secure, scalable and high performance application design

We have proven expertise in designing complex and mission critical architectures for Java. Our enterprise Java architects come with several years of development experience, and have been champions at adopting industry wide best practices and approaches while architecting solutions. Some consideration areas include:

• Refactoring and design patterns
• Make appropriate use of design patterns
• Make use of Java interfaces to improve design
• Tuning performance and scalability
• Use tools like Apache Jmeter to test the performance of the application
• Use profiling tools as often as needed
• Check the request-response time for applications
• Conducting load and stress tests
• Identifying performance bottlenecks
• Tune JVM and other application parameters
• Writing reliable, thread-safe code
• Avoiding race condition and deadlocks
• Select the best Java collection objects available
• Prevent memory leaks
• Authentication and authorization
• Apply role-based security authentication and authorization frameworks like ACEGI or Spring
• Authenticate the type and hierarchy of users in the web application
