The Business Reasons
Re-development of UNIX oriented system and expansion on the Windows oriented market.
Migration and double maintenance of an information management system.
Their primary goals:
- deliver in time ready for market software product
- extend Unix based product by newest features
- increase reliability of the system
- find cost effective solution how to migrate the product from J2EE to .Net
The Solution
iTechArt started from studying requirements and creating of our vision. Project was divided to three layers: representation, business logic and data storage. It was well for a starting point. iTechArt's team re-designed and implemented representation layer. Business logic and data storage were a part of the customer's development team. It was a very effective cooperation and we are kindly grateful for this.
The re-design is based on the following:
- ASP.NET and Struts web application architectures
- iTechArt unified the Model-View Controller paradigm for Web for Struts and Asp.Net
Struts Page generation process:
A browser request is submitted to and handled by the Action Servlet class, which has one physical instance per server. The Action Servlet calls the Request Processor to prepare the request and response objects, determine action mapping etc. The Request Processor creates (or re-uses) the corresponding Action Form bean, populates it with the input fields from the html form and invokes form validation (if required). Using the action mapping in its configuration file, the Request Processor passes control to the appropriate Action Class. The Struts framework pools instances of Action classes; therefore, if the action has already been requested, it will be retrieved from the instance pool, as opposed to being created with every request. However, without multi-threading, this can lead to significant collisions when multiple users are accessing the same action. The Action Class invokes business logic beans and passes the Action Form (or a portion of it) to the model. The model may be EJB-based, or consist of plain Java objects. After the action completes execution, it is returned as an Action Forward object which determines the target of the request. Control is finally returned to the Request Processor, which forwards the request to the appropriate target. The JSP page may get data from the Model through a set of tag libraries.
ASP.NET page generation process:
