Browser using JEditorPane forcing blue background

This is the code I'm using to display google in a JEditorPane

String url="http://google.com";     editorPane.setEditable(false);     try {         editorPane.setPage(url);     } catch (IOException e) {} 

But for some reason the background will always be a blue colour, doesn't matter if I call

setBackgroundColor(Color.WHITE);

As @AndrewThompson noted in the comments JEditorPane is really behind, it supports only a subset of HTML 3.2 and CSS1, and isn't really cable of rendering any modern web pages.

I strongly suggest using an alternative, like:

• JavaFX WebView

  Code Snippet: (no dependencies, you can run it as-is)

  import javafx.application.Platform; import javafx.embed.swing.JFXPanel; import javafx.scene.Scene; import javafx.scene.web.WebEngine; import javafx.scene.web.WebView;  import javax.swing.*; import java.awt.*;  public class JavaFxBrowser implements Runnable {     private WebEngine webEngine;      public static void main(String[] args) {         SwingUtilities.invokeLater(new JavaFxBrowser());     }      public void loadURL(final String url) {         Platform.runLater(() -> {             webEngine.load(url);         });     }      @Override     public void run() {         // setup UI         JFrame frame = new JFrame();         frame.setVisible(true);         frame.setPreferredSize(new Dimension(1024, 600));         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);          JFXPanel jfxPanel = new JFXPanel();         frame.getContentPane().add(jfxPanel);         frame.pack();          Platform.runLater(() -> {             WebView view = new WebView();             webEngine = view.getEngine();              jfxPanel.setScene(new Scene(view));         });          loadURL("http://www.google.com");     } } 

• Flying Saucer

  Code Sample:

  XHTMLPanel panel = new XHTMLPanel(); panel.setDocument("http://www.google.com"); 

  @see BrowsePanel.java

• or NativeSwing

  Code Snippet:

  final JWebBrowser webBrowser = new JWebBrowser(); webBrowser.navigate("http://www.google.com"); 

  @see SimpleWebBrowserExample.java

A possible reason is that HTMLDocument parses three-digit color codes differently from normal. Hence, everything is shown as blue because only the blue byte (and the lowest 4 bits of the green byte) is set.

For example: #FFF would be interpreted as #000FFF, which is sharp blue.

At least this solved my problem mentioned in the comments. A possible reason for related threads on the background, too.

It seems you have extended JFrame in your class. So please use editorPane Object for setting the color as below

String url="http://google.com";     editorPane.setEditable(false); editorPane.setBackground(Color.WHITE);     try {         editorPane.setPage(url);     } ca

I once tried using JEditorPane circa JDK1.3 and the support was awfully limited. From what i understand there has not been much advancements in that API to provide support for browsing.

I recommend you checkout DJ here. Simple to setup and use reliably.
