Hi Experts,


I have an application and a menu called Reports. From that menu I have to open an HTML file with a browser.
Actually I have a menu open that can open files but I can't open HTML files.
Can you help me with that.



Thank you

Here is my code
I've got the following error : Unhandled exception type IOException



class MyHTMLListener extends AbstractAction{
            
                         //display message dialog when user selects About ...
                    public void actionPerformed( ActionEvent event )
                    {
                    Runtime.getRuntime().exec("cmd.exe /c start" + "E:/JAVA DISTRIBUTION/My CTA Platform/jars/reports/SwingTrader--bund--Wed_Nov_15_225311_EST_2006/Summary.html" );
                    }
            
                   } // end anonymous inner class

You need to catch the IOException by surrounding the Runtime.getRuntime.exec() call with try-catch, like this:

try {
Runtime.getRuntime().exec("cmd.exe /c start" + "E:/JAVA DISTRIBUTION/My CTA Platform/jars/reports/SwingTrader--bund--Wed_Nov_15_225311_EST_2006/Summary.html" );
} catch (java.io.IOException e) { }

Can you please type "e.printStackTrace();" in your catch block and re-run it? See if there is any exception thrown.

Also, can you run it by typing the command in "Run" dialog ("Start->Run")?

Yes you're right it helped but I still can't get my HTML file....

I have a error message from Windows stating that it can't find E:/JAVA

I thing that the problem comes with the separated bars /. If I can this / with \ Java is not accepting it ??

I don't think so. You need to quote the url with double-quotes, as the following:

Runtime.getRuntime().exec("cmd.exe /c start" + "\"E:/JAVA DISTRIBUTION/My CTA Platform/jars/reports/SwingTrader--bund--Wed_Nov_15_225311_EST_2006/Summary.html\"" );

Oops... should be:

Runtime.getRuntime().exec("cmd.exe /c start " + "\"E:/JAVA DISTRIBUTION/My CTA Platform/jars/reports/SwingTrader--bund--Wed_Nov_15_225311_EST_2006/Summary.html\"" );

I don't know why I get this message E:\JAVA DISTRIBUTION\My CTA Platform\src\SteadFast>

since I have included this directory in my code E:/JAVA DISTRIBUTION/My CTA Platform/jars/reports/SwingTrader--bund--Wed_Nov_15_225311_EST_2006/Summary.html

and run as:
Runtime.getRuntime().exec("cmd.exe /c start " + "\"E:\\Summary.html\"" );

 Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " +
                                            "E:/JAVA DISTRIBUTION/My CTA Platform/jars/reports/SwingTrader--bund--Wed_Nov_15_225311_EST_2006/Summary.html".toString());

You need to use  JEditorPane if you want the html to be interpreted

When I do this I have the same problem as before nothing's happens

 try {
                            String url = "\"E:\\JAVA DISTRIBUTION\\My CTA Platform\\jars\\reports\\SwingTrader--bund--Wed_Nov_15_225311_EST_2006\\Summary.html\"" ";
                            JEditorPane editorPane = new JEditorPane(url);
                            editorPane.setEditable(false);
                       
                            JFrame frame = new JFrame();
                            frame.getContentPane().add(editorPane, BorderLayout.CENTER);
                            frame.setSize(200, 200);
                            frame.setVisible(true);
                        } catch (IOException e) {
                        }
