FormsFileWatcher

This is a Oracle Forms Proof-of-Concept demo for exchanging data files in a watched directory:

• producing and sending (write file)
• receiving and consuming (read file) .

Motivation

Interactions of Oracle Forms with other runtimes or virtual machines are sometimes difficult on the local front-end side.
A practical and simple solution is realized with exchanging data files in temporary watched directories.
Forms can send or receive files in watched directories, so there is a simple One Line Data Format for interacting used: Action|Parameter1|Parameter2 .. . You can apply to parse this simple format with the d2dlkstr2.pll library, modified from original d2dlkstr.pll.

This Forms solution includes the FormsFileWatcherPJC : https://github.com/Fxztam/FormsFileWatcherPJC .

Examples

• Ping-pong testing loop:

• C# sending demo "FileWatcherSend.cs"

Modul chk_fwatcherself.fmb

• Forms module view

• Sequence diagram

Modul FileWatcherSend.cs

This C# module https://github.com/Fxztam/FormsFileWatcher/blob/master/FileWatcherSend.cs sends Action2Forms and EOwatchSercice :

Running

This Oracle Forms module was tested on:

• Windows 10
• IE 11
• Java 8_151 32 Bit (11.151.2.12 x86)
• Oracle Forms 12.2.1.2.0 .

After signing the FormsFileWatcherPJC.jar with a certificate from a Trusted Certificate Authority, deploying this certificated JAR file and re-starting the Forms Weblogic Server you can test:

• Ping-pong testing loop:

  1. "Start"
  2. "Loop"
  3. "Stop"

• C# sending demo:

  1. "Start"
  2. "Run FileWatcherSend.cs"
  3. "Stop" .
