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

  8. Development Methodology / Tooling Problem • UI development was painful • Lots of coding with no help. • Long before Netbeans and Eclipse • Forte, Borland • Batch files, Notepad, and javac Solution • 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

  9. Deployment Problem • <applet>, <object> tags • Parameters • Class & resources loading • Start pages • Configuration detection Solution • 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

  10. Styling Problem • Graphic API limited • Fonts problematic • Limited AWT Widgets • Switching to Swing make development harder Solution • 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

  11. Server Integration Problem • How to deploy the application easily in a J2EE • RMI, JMS, HTTP • Data Integration • Leverage Web Server Frameworks • Struts, JSP/Servers Solution • 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

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