Facts and Truth


• My developers are very knowledgeable with PB
• My developers create PB Applications very quickly
• My developers don’t know about J2EE, C#, .NET
• My applications need to use the WEB ( INTRA-INTERNET)
• The economy is struggling
   – Reduced Budgets, Reduced Costs
   – I cannot hire neither dev nor contractors !!
• Arrrrghh !!! What should I do ?
• Hum if I could transform my PB APPS into RICH WEB APPS
  without re-engineering them …

  Appeon Server

• Appeon Server (Execution Components)
   – A set of Java, PowerBuilder and Servlets that access EAS services like
     EAS Connection Caches, Instances Pooling
   – The components are “stateless” for better performance
   – Document Printing is done thru Acrobat PDF Writer and directly if the GIF
     format is chosen
   – RoundTrips to the server are minimized thank to the Appeon JavaScript
     WEBLIB
   – The runtime generates a GUI as close as posible to the original CS
     Application
   – Intensive use of HTML, XML and JavaScript
   – Files ( XML, HTML, JPG, PDF, JavaScript, etc.) are downloaded to the
     client thru regular HTTP requests
   – No Need for Plug-ins, Java Applets, or ActiveX !


                                                                                 15
Appeon, Deployment Process


• Code Export of PB Objects ( srX…)
• Converts PB Code source to Unicode
• Converts Unicode to XML
• Analyzes XML files looking for unsupported features
• Converts those XML files to HTML, XML and compressed-encrypted
  JavaScript files
   – Appeon JavaScript WEB Library has a 1-1 mapping with existing
     PowerScript functions
• Deploys the WEB APP files to the Appeon Server




                                                                     16
Appeon, deployed files


        Object Type                         Output File
Entire Application           Index.html
Window, Visual User Object   2 HTML files + 1 JavaScript file
DataWindow                   XML file
NVO, Menu, Application       JavaScript file - In a future release, the
Object, etc.                 customer will decide whether NVOs
                             should run remotely in Appeon Server
                             or locally in encrypted JavaScript


– All JavaScript is compressed and encrypted which reduces the file
size > 50% and protects the customer business logic investment




                                                                          17
