Groovy lets the programmer decide to catch the exception or not. In the following example, the developer tries to open and read the contents of a file. He does not need to surround the method with a try and catch block, when he knows that the file exists. Continue reading “Groovy Exception handling”
The use of semicolons ( ; ) in Groovy is completely optional . The only time a semicolon has to be used, is when multiple function calls are placed on the same line Continue reading “Groovy basic language”
Grails is known as domain driven language that means we can build application using bottom to top approach which is more nearer to object oriented programming. GORM (Grail Object Relational Mapping) uses intern Hibernate to map the domain with table which gives life to Domain modeling. If we combined everything just only based on domain we could build the whole web application. Scaffolding can bring domain design directly to visible state to business users with extra involvement Continue reading “Grails – GORM Tutorial”
Grails is based on the Model-View-Controller (MVC) architectural pattern and favors convention over configuration Grails framework build on top of Spring MVC. It uses URL to identify the action & view and process CRUD using domain. Business logic constitute in Grails services which could be wired with controller using Spring DI (Dependency Injection) mechanism. Continue reading “Grails a Spring MVC Framework”
I discussed about RESTful architecture consideration and how to build RESTful web services using Jersey JAX-RS [JSR 311] in JAVA. Today I am going to discuss how to build the RESTful web services using Grails framework.
GRAILs framework is the platform which provides end to end solution to build web application from scratch to advance intuitive RIA web application. Grails potentially be a one-stop shop for all your enterprise application development. Grails is modular, allowing you to pick and choose which modules are applicable for your application Continue reading “Grails – RESTful Webservice using JAX-RS plugin”
Grails is a web framework based on Groovy and Java which can be deployed into existing Java web servers, e.g. Tomcat or Jetty. Its scaffolding capabilities let you create a new project within a few minutes. Grails is based on the “convention over configuration” idea which allows the application to auto-wires itself based on naming schemes (instead of using configuration files, e.gl XML files). Continue reading “Groovy & Grails Understanding – Part2”
Enterprises today require agile platform for rapid development of applications with ready assurance to quality of services, compliance to architecture and design standards. Two key things influence our ability to be agile. First, it’s the attitude of everyone involved. Second it’s the languages, framework, and tools we use to get our work done. Continue reading “Groovy & Grails Understanding – Part1”
