    Default Help with url

    Hi. Hope someone can give me a clue.

    I have a java standalone using Eclipse EE. I have an embedded browser which works fine if I throw 'bbc.com' at it.

    I have a text box where the users enters the url. A common entry would be ''.

    However using URI and URL having no luck and just don't see it. Tried lots of combinations. Any hints very welcome.

    Here my Listener.

    buttonurl.addSelectionListener(new SelectionAdapter() {
                public void widgetSelected(SelectionEvent e) {
            		URI uri = null;
            		URL url = null;
            		try {
    					uri = new URI(texturl.getText());
    				} catch (URISyntaxException e1) {
    					System.out.println("failed setting uri");
            		try {
    					url = uri.toURL();
    				} catch (MalformedURLException e1) {
    					System.out.println("failed creating url");

    This code even with simple bbc.com gives me the stack trace below. But if I pass bbc.com as a simple string no problem,

    Exception in thread "main" java.lang.IllegalArgumentException: URI is not absolute
    at java.net.URI.toURL(Unknown Source)
    at Path01class$31.widgetSelected(Path01class.java:156 6)
    at org.eclipse.swt.widgets.TypedListener.handleEvent( TypedListener.java:248)
    at org.eclipse.swt.widgets.EventTable.sendEvent(Event Table.java:84)
    at org.eclipse.swt.widgets.Display.sendEvent(Display. java:4353)
    at org.eclipse.swt.widgets.Widget.sendEvent(Widget.ja va:1061)
    at org.eclipse.swt.widgets.Display.runDeferredEvents( Display.java:4172)
    at org.eclipse.swt.widgets.Display.readAndDispatch(Di splay.java:3761)
    at Path01class.main(Path01class.java:2352)

    And if I try I get

    java.net.URISyntaxException: Illegal character in scheme name at index 0:
    failed setting uri

    having no luck
    Please copy the full text of the error messages and paste it here.

    Read the API doc for the URL class. Also it has a link to a site that defines what goes in a valid URL.
    The String you show: '' is missing the protocol.
    If you don't understand my answer, don't ignore it, ask a question.

    Norm many thanks. It's amazing just a little push in the right line of thinking and we are there.

    Having fed the embedded browser simple strings like 'bbc.com' and getting the correct result I thought I should be able to pass '' as I do with all external browsers. Guess I'll have to write a parser to pick up whatever the users throws in and build to the protocol. But much appreciated and enjoy your day.
