Users Manual

User Manual for use as JavaBean

The Sferyx JSyndrome  HTMLBrowser  Component Edition has been released as easy to use and configure Java Bean. If you intend to use it as component within an application then you can consult the javadoc documentation supplied with the product - it can be inserted as visual java bean into the editing environments such as Forte for Java, JBuilder or similar. It is sufficient to add the jar file to the component palette of the IDE and the icon of the  HTMLBrowser  should appear on the toolbar. The demo version is restricted and cannot be customized, it also takes automatically the default system look & feel.

User Manual for use with Oracle Forms

In order to use our  browser  in Oracle forms you should do the following steps:

1) Place the jar file in the class path of the oracle forms:

For example, if your installation folder is c:\orant, you have to place the jar file in the following folder:


2) Edit the /forms/server/formsweb.cfg file to add the jar file to the archive_jinit variable - this step is needed for the starting the form on the web

# Forms applet archive setting for JInitiator 
archive_jini=f90all_jinit.jar, HTMLBrowser.jar

3) Designing your form with the java bean and the Forms designer
- Open your form
- Add a "Bean area" to any block from the layout designer - there is a "Bean area" canvas on the toolbox and you can add it to any container on your form
- Set its Implementation class property to : sferyx.administration.renderers.HTMLBrowserOracleBean

That's all - if you have configured everything properly, the  browser  will appear inside your form. For setting variables and using its methods, please refer to the oracle help - the topic for using java beans with oracle forms. Further you can consult our FAQ - it contains some examples and tips on how to handle the  browser  in various situations regarding Oracle Forms.


User Manual for use with Eclipse SWT

1. How can I integrate the browser in an Eclipse / SWT Application?

 Place the jar file in the designer's build classpath and it will be loaded by the Eclipse environment. You can add this as follows:

Your project --> Build Path --> Configure Build path --> add HTMLBrowser.jar

and make sure to import all the necessary packages including org.eclipse.swt.awt.SWT_AWT

2. How to instantiate and load the class?

We have provided a special wrapper class sferyx.administration.renderers.HTMLBrowserSWTBean class which provides instant integration with just a few lines of code as follows:

Composite composite = new Composite(shell, SWT.NO_BACKGROUND | SWT.EMBEDDED);
Frame frame = SWT_AWT.new_Frame(composite);
HTMLBrowserSWTBean htmlBrowserSWTBean=new HTMLBrowserSWTBean();


The Sferyx JSyndrome HTMLBrowser is fully compatible and will run on any JRE 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 9, 10, 11, 12 ,13, 14, 15, 16 and higher. The provided wrapper classes like HTMLBrowserOracleBean and HTMLBrowserSWTBean make it also compatible with Oracle Forms environment and Eclipse/SWT environement.




If you use it as a javabean, the installation is quite simple and is sufficient to add the  HTMLBrowser  jar file (for example  HTMLBrowser Pro.jar) to the classpath of your application and include few lines of code for instantiating the HTML  browser  instance like:

sferyx.administration.renderers. HTMLBrowser   HTMLBrowser  = new sferyx.administration.renderers.HTMLBrowser();
 HTMLBrowser .setContent("Some html content"); //set some initial content
 HTMLBrowser .setRemovedToolbarItems("openFileButton, printFileButton"); //remove some toolbar items
