When a compiler with a web development company uses a code generator, internal representation of source code is converted into a distinct form which can be read and interpreted by the computer. It is generally used by the application developer. Present day has seen the introduction of many tools like Blu Age's M2Spring , Spring Roo framework from SpringSource, and Skyway Builder Community Edition version 6.3 which are useful for Java based custom application development.

Crucial reason why code generation included MDD (Model Driven Development) is gaining popularity for Custom application development in Java is that Java development now has several auto generated artifacts like XML to Java mapping files, Data Access Object (DAO), Log4J configuration files, and Spring. Let us learn the role of each unique code generator in little detail.

Spring Roo framework includes all the features that make it a circuit clout code generator able to generate almost all artifacts ...
... that might be used by a web development company in web application development. Command line shell allows command hinting, tab completion and context aware operations. Other functions of Roo for custom application development include:

->Generating automatic web tier for web user interfaces based on REST
->Managing the build configuration of files
->Facilitate creation of domain objects
->Develop applications in Spring in standard directory format

August 2009 saw the release of another code generator for custom application development called Skyway Builder Community Edition version 6.3. It encourages Spring MVC scaffolding techniques used to develop Spring based Java CRUD applications by a web development company from pre existing or new domain models. Spring DSL is inbuilt and has the ability to generate code for Spring Web Flow and Spring MVC solutions. Paid edition of Skyway Builder Enterprise Edition (EE) 6.3 for custom application development allows transformation of UML into functional Spring application due to its integration with IBM Rational Software Architect. DWR (JavaScript/JSON) compatibility allows developers use Spring services for RIA development as well as use JET technology for customization of code generation templates at project level.

A second name for IBM's MDD (Model Driven Development) is Rational Rhapsody. Some of its features include application code generation, requirements traceability, SysML and UML2, and design for testing (DFT). This is also a tater solution for custom application development and assists in creating project requirements using use-case diagrams, requirements diagrams, activity diagrams, state charts and sequence diagrams.

Users can use it for automatically providing traceability, create traceability links from the model to the requirements, coverage documentation as well as impact analysis. Support for a new archetype model driven testing (MDT) put the many advantages of MDD to testing. MDT boosts the custom application development process by allowing developers

->Repetitively imitate a design to find errors in the early stage
->Robotize the annoying testing process
->Amalgamate requirements-based testing to approve design against requirements
->Automatically create coverage tests from the design using IBM Rational Rhapsody Automatic Test Generation Add On capabilities

M2Spring is a product introduced by Blu Age and includes Blu Age Agile Model Transformation and MagicDraw UML which allow model and automatic code generation of application developed using Spring architecture. Supports various JEE and modeling technologies like Hibernate, XMI 2.1, UML 2.2, Struts, OCL 2.0m Spring and EMF UML2 2.x XMI. It also generates web application classes and archetypes in

->Service including web services, business rules and application services
->Presentation including user roles, security policies and user interface
->Persistence layers including DAO finder, DAO implementation and Business Objects

Custom application development service offered by Sparsh Technologies an acclaimed web development company, are compared to none as they use latest code generator.
