Purpose
Here is a Java Bean from Mark Striekwold to have an enhanced Web Browser (2nd edition). It is a full Web browser that can handle Javascript. This bean is based on the idea of the Full Web Browser Java Bean and rewritten so it makes use of the fbean package to register the bean and to call the methods of the java bean. It also makes use of a newer version of the jdic.jar which makes it easier to use under windows.
The material comes from the JDICplus project (WIN32 only):
https://java.net/projects/jdic
It can accept both http url and local machine html file names.
It needs, at least, a 1.6 JRE so the Sun Java plug-in, so that it won't run with the JInitiator and earlier version of the Sun Java plug-in.
The Java code
ehb.java
The implementation class of the Bean Item
oracle.forms.ms.ehb
The methods you can call
- Register the bean
fbean.register_bean('BL.BEAN', 1, 'oracle.forms.ms.ehb');
This is the very first operation you have to do.
- Get the Forms Window
fbean.invoke( '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
fbean.invoke( 'BL.BEAN', 1, 'setUrl', 'URL');
e.g. :
fbean.invoke( 'BL.BEAN', 1, 'setUrl', 'http://mark-oracle.blogspot.com');
- Set the border of the bean
fbean.invoke( 'BL.BEAN', 1, 'setBorder', '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
fbean.invoke( 'BL.BEAN', 1, 'setNavigation', 'back | forward | refresh' ) ;
e.g.:
fbean.invoke( 'BL.BEAN', 1, 'setNavigation', 'back');
The sample dialog
. Download the ehb.zip file
. Unzip the ehb.zip file
. Copy the ehb.jar file in your /forms/java/ folder
. Download the JDICplus project zip file
. Unzip the JDICplus-0.2.2-bin-win32.zip file
. copy the /lib/JDICplus.jar in your /forms/java/ folder
. copy the /lib/bin/jdicArc.dll and /lib/bin/jdicWeb.dll in your /windows/system32 folder
. Update your /forms/server/formsweb.cfg configuration file:
. archive=frmall.jar,ehb.jar,JDICplus.jar
. Notice that we update the archive tag and not the archive_jini tag because this bean needs the Sun Java plug-in 1.6 and won't run with any older version, including the Oracle JInitiator
. Open the EHBROWSER.fmb module (Oracle Forms 10.1.2)
. Compile all and run the module
The .jar files must be signed
The ehb.jar file provided with the .zip file are already signed
