Printing a html page through Swings

[S Krishnan]

I have generated a html page in a servlet and want to print it through Swings. The servlet where the generation of html page happens is a child servlet being called from within a loop of a parent servlet that is automatically activated by Jrun and NOT CALLED BY A CLIENT BROWSER.

If it's a simple HTML file ( Text only with Styles ) , you can open it in a hidden JTextPane ( or
JEditorPane ) and print this component.

I am having the problem of printing an HTML page displayed on a JEditorPane which is more than a single page. Here is my code . Please correct it . Thank you inadvance.



import javax.swing.*;
import javax.swing.text.*;

super("Test Pane");
setSize(600,700);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
we.getWindow().setVisible(false);
System.exit(0);
}});
JPanel urlPanel = new JPanel();
urlPanel.setLayout(new BorderLayout());
JTextField urlField = new JTextField(startingUrl);
urlPanel.add(new JLabel("Site: "), BorderLayout.WEST);
urlPanel.add(urlField, BorderLayout.CENTER);
final JLabel statusBar = new JLabel(" ");
jep.setEditable(false);
// force the pane to use our new editor kit
jep.setEditorKitForContentType("text/html", new HTMLEditorKit());
try {
jep.setPage(startingUrl);
} catch(Exception e) {statusBar.setText("Could not open starting page. Using a blank.");}
JButton btnPrint = new JButton("Print");
btnPrint.addActionListener(new ActionListener(){

printJob.setPageable(prepareBook(aPageFormat));

}

Hi,

If you don't mind can you tell me how to call a applet(it contains some swing components) from html page. I have used <applet code="Test.class" widhth=700 height=700></applet>, but it is showing some error in the browser statsu bar ie java.lang.ClassNotfoundExecption.

Some my friends adviced me to install HTMLConverter & Plugin. I don't how to use the HTMLConverter.

So can u tell how to call a applet from html page?

Hi,

You are asking this question again and again. I told a step by step instruction
in the following post.

http://codeguru.earthweb.com/bbs/wt/showpost.pl?Board=java&Number=15378&Searchpage=0&Limit=25

If you dont understand, or if you still have problems, please explain it clearly.
Do not just say "I don't how to use the HTMLConverter". I really dont think HTMLConverter
is that much complicated one to use.

Could you please tell me what did you do after you downloaded the HTMLConverter ?
Dont worry about Java plugin now. Just tell me what did you do after you downloaded
the zip file from the sun site.

Poochi...
