    Default problems with rendering HTML using JEditorPane

    i have this code to render a locally saved html file onto a jframe. i have the following problems with how the html was rendered:

    1. the texts of the 'webpage' do not wrap;
    2. in order to solve my problem in 1. above, i added a JScrollPane, problem is, the scrollbars do not appear.

    any help is appreciated. thanks.

    i have the code below:
    (main method -TryJEditor.java)
    import javax.swing.JFrame;
     
    public class TryJEditor {
     
    	public static void main(String[] args) {
     
    		TryHtml itry = new TryHtml();
    		itry.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		itry.setSize(500, 300);
    		itry.setVisible(true);	
    	}
    }

    (and the class - TryHtml.java)

    import java.awt.*;
    import java.io.File;
    import java.io.IOException;
    import java.net.MalformedURLException;
    import javax.swing.*;
     
    public class TryHtml extends JFrame {
     
    	private JEditorPane HtmlPane;
    	private JPanel pane;
    	private JScrollPane scroller;
    	private String url = "file:///D:\\Java Exercise Programs\\TryJEditor\\myhtml.htm";
     
    	public TryHtml() {
    		super("title");
    		FlowLayout fl = new FlowLayout(FlowLayout.LEFT);
    		setLayout(fl);
     
    		pane = new JPanel();
    		try {
    			pane = new JPanel();
    			HtmlPane= new JEditorPane(url);			
    			HtmlPane.setContentType("text/html");
    			HtmlPane.setEditable(false);
    			HtmlPane.setSize(500, 250);	
    			scroller = new JScrollPane(HtmlPane, ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
     
    		} catch (IOException e) {
    			e.printStackTrace();
    		}
     
    		pane.add(scroller);
    		add(pane);
    		pack();		
    	}
    }

    It would help to have myhtml.html as well, since that file is required to run your code.

    disregard.. i found some ideas from the internet.
    i just added this new line after creating the JScrollPane.

    scroller.setPreferredSize(new Dimension(int, int));
