    JTextPane trouble

    I am an email client. I want to be able to send the emails in rich-text format, so the GUI uses a JTextPane as the Text Component in which the user's message is entered. The problem is that when I call textPane.getTex t() the returned string contains only HTML tags, no actual text. So my question is how do I get the HTML content from a JTextPane, including tags and text, to use in a JavaMail application? Here is the jist of what I have tried:

    Code:
    //a lot of GUI code

JTextPane textPane = new JTextPane();
textPane.setEditorKit( new HTMLEditorKit() );
textPane.setDocument( new HTMLDocument() );

//more GUI code

String message = textPane.getText();

//then code to send the email
    Having entered some arbitrarily formatted text and calling System.out.prin tln(message) the following output is produced. (The output of course varies with the random non-sense I enter into the JTextPane whilst testing, but it is always only tags)

    Code:
    <html>
  <head>

  </head>
  <body>
    <p style="margin-top: 0">
      <font face="Dialog" size="3"><Dialog>
      <u><Dialog>
      </u><b><Dialog>
      </b></font><b><font face="Dialog" size="7"><Dialog>
</font></b>    </p>
  </body>
</html>

      What happens when you ask your HTMLEditorKit to write its entire content? Read the API docs for the details of its write() method. For the actual Writer you can use a StringWriter so you can get the content as a String later.

      kind regards,

          I have tried that, with the same result. I combed the API and thought this would work, but it does the same thing - prints only the tags.

          Code:
          HTMLEditorKit kit = (HTMLEditorKit)textPane.getEditorKit();
HTMLDocument doc = (HTMLDocument)textPane.getDocument();
StringWriter writer = new StringWriter();

try{
kit.write( writer, doc, 0, doc.getLength() );
System.out.println( writer.toString() );
}
catch( IOException ie ){
//code to handle exception 
}

              I have a question for you: can you post a (preferably short) example that shows the behaviour you described, so that I can play with it? The API doesn't give me an answer and I find it a bit strange that there would be no way to get the original html back (I don't really care about comments in the text).

              kind regards,

              Jos

                  Well Jos, in the process of writing a small example for you I discovered the problem. For some reason setting more than one attribute at a time with SimpleAttribute Set causes the JTextPane to get confused and lose the text. So I modified the code to change only one attribute at a time, and voila. Thanks for the help

                      You're welcome of course; what just happened to you is typical when you write an SSCCE, i.e. the mistake bubbles up to the surface and you're able to solve your problems yourself ;-)

                      kind regards,
