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


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

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

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

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“

 Debugging

 Breakpoints

 Development i th d b

 I do 80% development in the debugger


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


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


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


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


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.
