following may help u for deploying existing developer applications on web
Procedure:
1. The conversion is automatic when opening the 4.5 form in
Developer 6.
2. Convert all Icons to GIF files, OCX and VBX controls to
appropriate similar java beans control, Remove User Exits, Host
commands and Reading and writing files using TEXT_IO, Mouse
Move/Enter/Leave event triggers appropriately to meet the functionality
provided by them.
3. Write the separate HTML scripts file for every entry point into
the application. The HTML file will contain the relevant form name and
parameters hard coded. But if using Oracle Application Server, Forms
server cartridge will create HTML pages automatically.
4. Set up Middle tier with developer server and all forms with
HTML script files loaded
Restrictions:
5. All Icons need to be converted to GIF files - warning only
about the top left 9x9 will display!
6. If you want to display toolbars and/or a status line then on
the Property page of the form set the CONSOLE WINDOW to a valid window
(any one will do)
7. Menu items can be added to the toolbar by setting horizontal
toolbar to true and adding an appropriate icon
8. OCX and VBX controls are not supported. Because the user
interface is not on the same machine as the runtime engine, there is no
way for the control to display. Developer forms server 6.0 supports the
use of java beans, so the functionality provided these controls should
be replaced by a similar java beans control
9. User Exits, Host commands execute on the middle tier, not on
the java client. Therefore, they can not carry out any user interface
because the display used by the user is not the one on the middle tier.
10. Reading and writing files using TEXT_IO package takes place on
the middle tier. Therefore, a local file from the end user’s machine
cant be read, unless user’s drive is shared and is visible from the
form server machine. If user machine is not shared, Java Beans should
be used.
11. Mouse Move/Enter/Leave event triggers are disabled when running
over the Web in order to prevent the network from being swamped with
mouse messages, if these event triggers r used in the form, they should
be changed appropriately.
Oracle Software Required:
12. Oracle developer 6.0 and developer server. 13. Any web server. Oracle Application Server is not essential -any Web server will do. However if the HTML pages are required to be generated automatically, OAS is required and this will help in Cartridge implementation.
14. Jinitiator is required
