Java EE (J2EE) outsourcing software development

Our software engineers have been leveraging J2EE in outsourcing projects since 1999, when Sun Microsystems first introduced this platform. Exigen Services' Java portfolio includes hundreds of successfully delivered products ranging from small software utilities to large enterprise applications containing several million lines of code. Among Exigen Services 600+ Java developers, there are many certified by Sun or other Java-based platform solutions providers like Oracle, IBM or JBoss.

The key to a successful Java EE solution implementation is not only a thorough knowledge of the Java language, but also having extensive experience with various technologies, frameworks and libraries, such as: JSF, Spring, Hibernate, Struts, and others. Most of which were produced by well-established open source Java-communities developed and improved by hundreds of software developers around the world. For the past 9 years, our engineers continually strive to define the right balance between the proven, but aging technologies and the promising, but younger technologies.

This approach allows Exigen Services to considerably decrease time to market while maintaining a high level of quality and reliability by applying our best practices experiences from past projects. Specifically, one of the most important aspects that customers expect from a Java EE solution is scalability. Designing an easily-scalable solution requires expertise in EJB out-of-the-spec and implementation specific knowledge of particular application servers like BEA WebLogic, IBM WebSphere, OC4J, JBoss AS or Sun GlassFish. We have significant experience building cluster solutions on various platforms like x86-64, IBM pSeries, and others.

Quality is the top priority for us. Exigen Services believes that quality assurance needs to be introduced on all levels of a project including, but not limited to, development. In our projects, we utilize automated testing (unit tests, integration tests) in conjunction with a continuous integration approach to instantly track code quality. Frequent refactoring enables our engineers to generalize specific changes performed on different parts of the system, thus allowing system architecture to evolve rather than become outdated and patch-based.

Another important aspect of software development of the enterprise-level systems is security. It is difficult to underestimate the importance of this requirement, especially in such areas like financial institutions or healthcare organizations. Our engineering approach, based on variety of available j2ee security instruments (such JAAS, Java ACC, Acegi/Sprint security, etc) and successfully supported by application security testing practice, allows us to deliver solutions even for highly-regulated industries.

To maintain an efficient company strategy within a changing environment, we do all that is necessary to simplify change implementation to a source code process. Code documentation follows a defined architecture and clear coding convention which enables Exigen Services specialists to locate and eliminate defects, even in a large and complex source code hierarchy. In addition, our engineers follow industry standards produced by W3C, JCP Executive Committees, OASIS and other respected bodies to decrease the risk of incompatibility of the developed system with future versions of third party software.

This combination of innovative technologies and advanced project methodologies enables Exigen Services to provide our customers with world-class Java EE/J2EE outsourcing software development services.
