                final String path= this.editorPane.getPage().getFile();
                final File f = new File(path);
                this.fc = new JFileChooser(f);
                fc.setSelectedFile(f);
                final int returnVal = fc.showSaveDialog(this);
                if(returnVal == JFileChooser.APPROVE_OPTION) {
                      ClassLoader classLoader = this.getClass().getClassLoader();
                      File f = new File(classLoader.getResource(path).getFile());

I have an HTML file residing in my JAR file. I would like to copy it from the JAR file to a place on the hard drive. So far I have worked out choosing the name of the file and where it should be copied. The HTML file is shown in a JTextPane. I do not need to make any modifications to the HTML file. Just need to allow the user to save it anywhere. I am not sure if I need to write the reference f located on the last line.

If you know where in the JAR file the HTML file is found, use Class.getResourceAsStream to get a an InputStream to the HTML file. Then simply copy the contents of the InputStream to the FileOutputStream you create for fc.getSelectedFile().

Thanks for your reply Rob Prime. Of course I know where the HTML file resides in the JAR file. I was quite sure this had something to do with InputStream, but was not sure enough to use it, and vesides, it is quite hard to understand. I was able, so far, to get the InputStream part ot work without throwing an exception. More work neeed though. Thanks for the tip. Isaac.
