What operating systems and platforms does AjaxSwing
run on?
AjaxSwing is written purely in Java and it doesn't use any native calls, which
means that it runs on most platforms that have Sun's JDK 1.2 and up.
However, because AjaxSwing integrates very closely with JVM we can only
guarantee correct execution on the platforms that we have tested. So far
this includes Windows NT, Windows 2000, Solaris, HP-UX, IBM AIX and Linux.
What web servers and servlet engines can I use
with AjaxSwing?
Any web/app server or servlet engine that runs Sun's JDK 1.2.2 and higher and
JSDK 2.1 and higher. For a complete list and details on how to setup AjaxSwing
with your servlet engine refer to Installation and Setup
instructions.
Will AjaxSwing really web-enable any application?
The first thing to do is to check that your application can run on
the server where you are trying to deploy it. Just run it as an application
and test the functionality. Our product has been tested on numerous applications
and has many successful deployments. Most of the times you would see 95% of
your application working as HTML portal right after 30 minute configuration of AjaxSwing.
However, certain problems may arise from the fact that your application is accessed
through HTML. For example, not all GUI events are sent to your application
for performance considerations so if you enable/disable certain controls when
a "change" event is received, your interface will not work as expected.
It's not a problem of AjaxSwing or your application but rather a limitation
of HTML and the Internet speed. Thus, you may have to make minor changes to
your application user interface for it to look better and function properly
in HTML, but using AjaxSwing gives you a tremendous advantage compared to rewriting
your application using Servlets/JSPs or writing both GUI and HTML clients.
Are there step-by-step instructions on setting
up AjaxSwing and web-enabling my application?
Yes. Please refer to Installation and Setup instructions.
Does AjaxSwing support custom controls (e.g. my
own controls, JBCL, KLGroup JClass)?
AjaxSwing supports most AWT and Swing controls and all controls derived
from it. This means that if the custom control extends a standard control
above java.awt.Component or javax.swing.JComponent then it will be automatically
supported. Of course it is going to be presented in HTML just like the
original AWT/Swing control would have been. For example if you create
a custom control that extends JComboBox then it will be supported and
converted to HTML menu. You can change the default rendering by writing
custom renderers.
Can I customize AjaxSwing to change the default
mapping of GUI components to HTML elements?
Yes. A number of configurable parameters are specified in the application
properties file located in the conf directory of AjaxSwing. For details
on the meaning of each parameter refer to Customizating
and Configuring AjaxSwing. For advanced customization you can write
your own Renderers and ActionEmulators that will override the default
implementation provided by AjaxSwing. Renderers generate HTML for Java
controls and ActionEmulators set values back to Java controls and emulate
actions as though performed by the user (for example button click). This
functionality is not provided in the Standard Edition. Follow the link
to learn about developing custom renderers.
How can I integrate AjaxSwing
application into a JSP or HTML page?
The easiest and the cleanest way to integrate AjaxSwing output into a JSP or HTML page
is to use <IFRAME> or <FRAME> tag.
CreamTec website
uses this approach to display demos in the context of the site.
Do I need to have a Java plugin to view pages
generated by AjaxSwing?
No. You use any standard browser because all it gets is HTML. It doesn't
even need to support Java because the Java application executes on the
server.
What AWT and Swing components and classes are supported
by default by AjaxSwing?
| AWT |
Button, CheckBox, Choice, Label, List, MenuBar, TextArea, TextField,
Panel, Window |
| Swing |
Box, BoxFiller, Icon, JButton, JCheckBox, JComboBox, JDesktopPane,
JEditorPane, JInternalFrame, JLabel, JLayeredPane, JList, JMenuBar,
JOptionPane, JPanel, JProgressBar, JRadioButton, JRootPane, JSlider,
JSeparator, JScrollBar, JScrollPane, JSplitPane, JTable, JTabbedPane,
JTextArea, JTextField, JToggleButton, JToolBar, JTree, JViewport,
JavaHelp (via Override Action), JFileChooser |
| Layouts |
All layouts are supported through the use of fixed positioning.
Elements on generated HTML pages have their left, top, width and height specified to be exact same value as the Swing component they represent.
|
AjaxSwing provides a universal SnapshotRenderer
that can render any component as an image on the page. It can be used for custom
components and as an alternative method of rendering a component in HTML.
What GUI events are supported by
AjaxSwing?
ActionListener, FocusListener, ItemListener, DocumentListener,
TreeSelectionListener, ListSelectionListener (for DefaultListSelectionModel only)
How does AjaxSwing determine the name of the
downloaded file when emulating JFileChooser Save dialog?
AjaxSwing calls JFileChooser.getSelectedFile() method to determine the name of the file.
If the method returns null, AjaxSwing uses the default download.txt file name.
Thus, be sure to set the default file name to the JFileChooser as shown below:
JFileChooser chooser = new JFileChooser();
chooser.setApproveButtonText("Select file for export");
chooser.setSelectedFile(new File("application_export.txt"));
int returnVal = chooser.showSaveDialog(this);
if(returnVal == JFileChooser.APPROVE_OPTION) {
File file = chooser.getSelectedFile();
// Save data to the selected file
...
}
