XForms Interview Questions And Answers

XForms is a GUI toolkit based on Xlib for X Window Systems. It features a rich set of objects, such as buttons, scrollbars, and menus etc. integrated into an easy and efficient object/event callback execution model that allows fast and easy construction of X-applications. In addition, the library is extensible and new objects can easily be created and added to the library.

We use XSLT to generate HTML from an internal representation. This means that users of PresentationServer can easily customize the stylesheets and fully control the generated HTML. At this point, we generate "classic" HTML and use JavaScript very sparsely

Rendering is performed with XSLT. We provide a stylesheet that generates HTML out of the box, but one could write his/her own stylesheet that generates SVG or XUL without too much difficulty, by looking at the existing stylesheet that comes with OPS.

The XForms engine is implemented in two processors. Since processors can be called through a Java API, the XForms engine could be used stand-alone and, say, called directly from a Servlet.

PresentationServer is often compared to Cocoon as both are platforms for building Web applications and they both use XML technologies, and are both open source. We have on our Web site a page linked from the FAQ comparing PresentationServer with Cocoon.

Alessandro Vernet: PresentationServer is not so much about adding extensions to XForms, it is rather about providing the features related to XForms that application developers need. Once a form has been submitted by the end-user and the XForms engine has created an XForms instance document that contains the data entered by the end-user

This life cycle is used for standard applications that are built from various custom technologies and follow the normal or standard testing approach. The Application or custom-build Lifecycle and its phases is depicted below:
► Requirement Specification documents
► Functional Specification documents
► Design Specification documents (use cases, etc)
► Use case Documents
► Test Trace-ability Matrix for identifying Test Coverage
► Test Scope, Test Environment
► Different Test phase and Test Methodologies
► Manual and Automation Testing
► Defect Mgmt, Configuration Mgmt, Risk Mgmt. Etc
► Evaluation & identification – Test, Defect tracking tools
► Test Bed installation and configuration
► Network connectivity’s
► All the Software/ tools Installation and configuration
