  • 4. Presentation P t ti  It all started back in 2000…  Existing application  Insurance application  Management of new and existing life insurance contracts  Needed to build Java Frontend  Distributed environment  Implemented a facade- based access to Smalltalk  Over the years…  We used the same technology to build  Smalltalk Clients  C# Clients  Copyright Natural Software SL, 2009 - 2010
  • 5. Existing E i ti application li ti  Existing large scale application  Complex architecture  Access to DB via CICS/Cobol  Model driven approach  Complex business object model  Existing Rule engine  Very small granularity of rules being used y g y g  Basically every entry is checked  Copyright Natural Software SL, 2009 - 2010
  • 6. Architecture A hit t  Existing large scale application CICS Host GUI EOM Service VASER Frameworks Project DB/2 Smalltalk application (Rich client) Database  Copyright Natural Software SL, 2009 - 2010
  • 7. New D N Development l t  Requirement  Turn the „rich client“ application into a advanced, distributed application  Build a Java Frontend  Use AWT (2000)  Later Swing ( g (2003) )  „Re-Use“ existing application as central backend  Transformation from „Rich client“ to „Server“  Multiple M lti l parallel t ll l transactions ti  Multiple concurrent instances of the object model  ~~14.000 Clients in ~~3.000 locations using 7 servers  Copyright Natural Software SL, 2009 - 2010

  • 9. Requirements R i t  Access to the object model from a Java frontend  Low granularity  Methodlevel (Action)  Fast  On O method executions, normal rule checking h t th d ti l l h ki has to occur  Scalable  Target: 14.000 Clients using 7 Servers  Copyright Natural Software SL, 2009 - 2010

  • 11. Facades F d Repository Provides Object Id j Function call Message send Smalltalk perform Java Facade Business m Object Object Result Id Result  Copyright Natural Software SL, 2009 - 2010
  • 12. Facades F d  Java Facade for a Smalltalk Object  Actions  Actions may b performed and may change attributes A ti be f d d h tt ib t  Attributes  Changes in attributes invalidate derived attributes  Cache for server values  Behaves „like a Smalltalk Object“  Copyright Natural Software SL, 2009 - 2010
  • 13. Cool t ff C l stuff  aFacade i F d inspect t  Debugging  Breakpoints  Development i th d b D l t in the debugger  I do 80% development in the debugger  Copyright Natural Software SL, 2009 - 2010
  • 14. Analysis A l i  Network Latency biggest p y gg performance issue  Block size 1 2k Byte 1…2k  Number of datablocks and parallel sockets was/is not an issue  Copyright Natural Software SL, 2009 - 2010
  • 15. Other f Oth functionality ti lit  Event propagation  Facades have to be marked invalid, if someone else changes a value  Solution: E S l ti EventManager waits on events for tM it t f registered objects  Copyright Natural Software SL, 2009 - 2010
  • 16. Event propagation E t ti  Distribution of changes  Objects are marked read-only  If read-only exception  Change will be done anyway  Object fires events to registered facades to invalidate j g attribute value  If required – client facade reloads  Copyright Natural Software SL, 2009 - 2010
  • 17. Other f Oth functionality ti lit  Garbage Collect g  Side effect of event propagation  All remote objects are in a weaktable (RemoteRepository)  Remote usage is a object reference  If taken out, they send a special event  Copyright Natural Software SL, 2009 - 2010
  • 18. Other f Oth functionality ti lit  Performaning an action requires  Invalidating and reloading all attributes I lid ti d l di ll tt ib t  Reloading all attribute descriptors  Type T  Fieldlength (for databasemapping)  Infotext (Information about each attribute like „value has to be between x and y“)  Messages  Information, Warning, Error, etc.  Copyright Natural Software SL, 2009 - 2010
