A Full Web Browser Java Bean

Purpose

Here is a Java bean that allows to have an enhanced Web Browser.
It is a full Web browser that can handle Javascript and display Flash animations.

The material comes from a sourceforge project:
http://sourceforge.net/project/showfiles.php?group_id=170904

It can accept both http url and local machine html file names.

It needs, at least, a 1.4 JRE so the Sun Java plug-in, so that it won't run with the JInitiator.


The Java code

     EnhancedHTMLBrowser.java



The implementation class of the Bean Item

     oracle.forms.fd.EnhancedHTMLBrowser


The methods you can call

• Get the Forms Window

Set_Custom_Property( 'BL.BEAN', 1, 'INFOBEAN', '' ) ;

This must be used to retrieve the Forms window that handles the webBrowser, then synchronize its position when the windows is moved. This must be the first property set (in the When-New-Form-Instance trigger).

• Set the URL/File

Set_Custom_Property( 'BL.BEAN', 1, 'SET_URL', 'url | file_name' ) ;


e.g. :

Set_Custom_Property('BL.BEAN', 1, 'SET_URL', 'http://www.developpez.com/' ) ;         


Set_Custom_Property('BL.BEAN', 1, 'SET_URL', 'd:/mypage.htm' ) ;

• Set the border of the bean

Set_Custom_Property( 'BL.BEAN', 1, 'SET_BORDER', 'true | false' ) ;


When you want to use this bean to display a Flash image (*.swf), you would probably prefer not to have any border bounding the image.
In this case, set the border to false.

• Basic navigation

Set_Custom_Property( 'BL.BEAN', 1, 'SET_NAVIGATION', 'back | forward | refresh' ) ;



The sample dialog

     . Download the eHTMLBrowser.zip file
     . Download the sourceforge project zip file
     . Unzip the files
     . copy the jdic.jar and eHTMLBrowser.jar files in the <ORACLE_HOME>/forms/java directory
     . Edit your /forms/server/formsweb.cfg file to add these 2 jar files
     . Add the 2 .dll files and IeEmbed.exe (from the javaflashbridge-v1.zip file) to your Windows/system32 directory
     . Open the EHTMLBROWSER.fmb module (Oracle Forms 9.0.2)
     . Compile all and run the module

     The .jar files must be signed
     The eHTMLBrowser.jar and jdic.jar files provided with the .zip file are already signed

Hello,

I followed all the mentioned steps and the form opens in the application, but the Browser is not displayed in the form.
Could anyone please suggest on this: what could be the reason(s).

Regards,
Samir

Hi,


I use JInitiator 1.3.1.22, and I also have installed on my machine the java JRE 1.6.0, but was configured as formsweb.cfg orientation. but not open the page properly, or does not work, as I am
novice in java, I do not know how to load a jar out of JInitiator + Java, or a jar that is not configured into the JInitiator. Could you give me an example of a forms without JInitiator running
or active with a java class that is configured and outside Jnitiator.

Below the configuration of formsweb.cfg

Thank you for your attention and patience.
