JTextPane with HTMLEditorKit: missing content when saving
Hi
When trying to save an HTML document to disc I only get HTML tags saved without any content. Similar topic was reported in this forum some time ago (see http://forum.java.sun.com/thread.jspa?threadID=700324&messageID=4066928), however the solution (as well as many other tips from other places) didn't help.
Here is the example code:
import java.awt.BorderLayout;
import java.awt.Color;
import java.io.File;
import java.io.FileWriter;
import javax.swing.JFrame;
import javax.swing.JTextPane;
import javax.swing.SwingUtilities;
import javax.swing.text.BadLocationException;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.StyleConstants;
import javax.swing.text.html.HTMLDocument;
import javax.swing.text.html.HTMLEditorKit;
/**HTMLWriter: starts a JTextPane, generates an HTML test document and saves it to file
* -> it displays the text correctly in the pane, but it doesn't save the content to the file
* @author Chris
*/
publicclass HTMLWriterextends JFrame{
protected JTextPane m_editorPane;
protected HTMLDocument m_doc;
protected HTMLEditorKit m_editorKit;
/** Creates a new instance of HTMLWriter */
public HTMLWriter(){
//Create the text pane and configure it.
m_editorPane =new JTextPane();
m_editorKit =new HTMLEditorKit();
m_editorPane.setEditorKit(m_editorKit);
//Create the document and initialize it
m_doc = (HTMLDocument)m_editorKit.createDefaultDocument();
// m_doc.setAsynchronousLoadPriority(-1);
m_editorPane.setDocument(m_doc);
String initString ="Some text2";
SimpleAttributeSet attr =new SimpleAttributeSet();
StyleConstants.setFontFamily(attr,"SansSerif");
StyleConstants.setFontSize(attr, 16);
StyleConstants.setForeground(attr, Color.red);
try{
m_doc.insertString(m_doc.getLength(), initString +"\n", attr);
}catch (BadLocationException ble){
System.err.println("Couldn't insert initial text.");
}
//Add the components
getContentPane().add(m_editorPane, BorderLayout.CENTER);
//Save the document to c:\temp.htm (MS Windows)
File f =new File("c:\\","temp.htm");
try{
FileWriter fw =new FileWriter(f);
int len = m_doc.getLength();
m_editorKit.write(fw, m_doc, 0, len);
/* I also tried to generate a new HTMLEditorKit object:
HTMLEditorKit newKit = new HTMLEditorKit();
newKit.write(fw, m_doc, 0, len); */
fw.flush();
/* I also tried passing OutputStream object to m_editorKit.write():
OutputStream out = new BufferedOutputStream(new FileOutputStream(f));
int len = m_doc.getLength();
m_editorKit.write(out, m_doc, 0, len);
out.close();
*/
}catch (Exception exSave){
System.out.println(" Error while Saving : " + exSave.getMessage());
}
}
publicstaticvoid main(String[] args){
final HTMLWriter frame =new HTMLWriter();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
}
The output in c:/temp.htm looks as follows:
<html>
<head>
</head>
<body>
<p style="margin-top: 0">
<font size="5" face="SansSerif" color="#ff0000">
</font>
</body>
</html>
I work with NetBeans 5.5 and JDK 1.6.
Thank you for your help!
