My 1999 Client-side Evaluation

What are the issues with Java? Development Methodology Tooling Deployment Styling Server-side integration Size and versioning of JVM JVM Installation Start up time

Fixing the Problems The problems can be solved Need to define issues Need a desire to fix them Get it done!

Development Methodology / Tooling UI development was painful –Lots of coding with no help. Long before Netbeans and Eclipse –Forte, Borland Batch files, Notepad, and javac Markup + POJO –Created a markup language to define the user interface and connect components to event handlers and data DOM Model + xPath Support Integration with Eclipse IDE –Visual Editor for Screens –Drag and Drop data binding Solution Problem

Deployment, tags Parameters Class & resources loading Start pages Configuration detection Handled automatically Server-side configuration of all startup parameters Nexaweb handles all class and resource loading –Custom Class loader the is integrated with the server Default start page Solution Problem

Styling Graphic API limited Fonts problematic Limited AWT Widgets Switching to Swing make development harder Wrote from the ground up our own widget library –Built on lightweight AWT component, JDK 1.1 Complaint External styling using CSS like configuration State based styling Extensible Pixel level controls Solution Problem

Server Integration How to deploy the application easily in a J2EE –RMI, JMS, HTTP Data Integration Leverage Web Server Frameworks –Struts, JSP/Servers Markup + POJO –XML is rendered on the client side Internet Messaging Bus Data Binding (XML, POJO) Server-side Control of the Application –Java APIs, xModify Solution Problem

Improve Download Size Improve Startup Time –No more spinning coffee cup Motivated by JavaFX Release this Year Consumer JVM
