    Unhappy Java Image Query Problem

    Hello. I am posting here, as I am having a problem, maybe more. What I am trying to do is to emulate a Google Image Search.
    I found a way to do this by using no special APIs as I am completely unfamiliar to this kind of practice. What I am trying to do in order to grab an image query
    is this:
    Append my query term to the following link:

    http://ajax.googleapis.com/ajax/serv...mages?v=1.0&q=


    You can see the actual page here:
    http://ajax.googleapis.com/ajax/serv...?v=1.0&q=panda
    This will return a result like:

    Code:
    {"responseData": {"results":[{"GsearchResultClass":"GimageSearch","width":"640","height":"480","imageId":"ANd9GcQRrzUNljCTG8-I68KUD8-SI2uwG77AYHvCcA50IFu4cs9WDK2DV9zHgnc","tbWidth":"137","tbHeight":"103","unescapedUrl":"http://assets.worldwildlife.org/photos/144/images/hero_small/Giant_Panda_Hero_image_(c)_Michel_Gunther_WWF_Canon.jpg?1345515244","url":"http://assets.worldwildlife.org/photos/144/images/hero_small/Giant_Panda_Hero_image_(c)_Michel_Gunther_WWF_Canon.jpg%3F1345515244","visibleUrl":"worldwildlife.org","title":"Giant \u003cb\u003ePanda\u003c/b\u003e | Species | WWF","titleNoFormatting":"Giant Panda | Species | WWF","originalContextUrl":"http://worldwildlife.org/species/giant-panda","content":"Giant \u003cb\u003ePanda\u003c/b\u003e","contentNoFormatting":"Giant Panda","tbUrl":"http://t0.gstatic.com/images?q\u003dtbn:ANd9GcQRrzUNljCTG8-I68KUD8-SI2uwG77AYHvCcA50IFu4cs9WDK2DV9zHgnc"},{"GsearchResultClass":"GimageSearch","width":"606","height":"387","imageId":"ANd9GcSE2zijRhPrLfVHuzROQrMbd3AXdutJwWiUyqysnDnUK07UjOlWdDJHOZHU","tbWidth":"136","tbHeight":"87","unescapedUrl":"http://www.washingtonpost.com/rf/image_606w/WashingtonPost/Content/Blogs/in-the-loop/Images/2012-09-17T130533Z_01_TOR901_RTRIDSP_3_USA-PANDA-WASHINGTON-218.jpg","url":"http://www.washingtonpost.com/rf/image_606w/WashingtonPost/Content/Blogs/in-the-loop/Images/2012-09-17T130533Z_01_TOR901_RTRIDSP_3_USA-PANDA-WASHINGTON-218.jpg","visibleUrl":"articles.washingtonpost.com","title":"National Zoo welcomes baby \u003cb\u003epanda\u003c/b\u003e - Washington Post","titleNoFormatting":"National Zoo welcomes baby panda - Washington Post","originalContextUrl":"http://articles.washingtonpost.com/2012-09-17/local/35498108_1_panda-cub-panda-reproduction-baby-panda","content":"Zoo welcomes baby \u003cb\u003epanda\u003c/b\u003e","contentNoFormatting":"Zoo welcomes baby panda","tbUrl":"http://t1.gstatic.com/images?q\u003dtbn:ANd9GcSE2zijRhPrLfVHuzROQrMbd3AXdutJwWiUyqysnDnUK07UjOlWdDJHOZHU"},{"GsearchResultClass":"GimageSearch","width":"948","height":"964","imageId":"ANd9GcQnXahbarc0laLmKjf4Rz9JYwVdWPfsWlF1rb_ytZTIzcg2akZaoskVxcCT","tbWidth":"146","tbHeight":"148","unescapedUrl":"http://media.npr.org/assets/img/2012/01/04/ap99121501386_custom-feedbb6efa738efee47e7828e805758dc427fa60-s6-c10.jpg","url":"http://media.npr.org/assets/img/2012/01/04/ap99121501386_custom-feedbb6efa738efee47e7828e805758dc427fa60-s6-c10.jpg","visibleUrl":"www.npr.org","title":"What The \u003cb\u003ePanda\u003c/b\u003e Won\u0026#39;t Tell Us : Krulwich Wonders... : NPR","titleNoFormatting":"What The Panda Won\u0026#39;t Tell Us : Krulwich Wonders... : NPR","originalContextUrl":"http://www.npr.org/blogs/krulwich/2012/01/03/144633582/what-the-panda-won-t-tell-us","content":"Every giant \u003cb\u003epanda\u003c/b\u003e, said","contentNoFormatting":"Every giant panda, said","tbUrl":"http://t1.gstatic.com/images?q\u003dtbn:ANd9GcQnXahbarc0laLmKjf4Rz9JYwVdWPfsWlF1rb_ytZTIzcg2akZaoskVxcCT"},{"GsearchResultClass":"GimageSearch","width":"948","height":"711","imageId":"ANd9GcT3wJ6FzzTa01idfln9jm2pNKC8YJFAJGsMim0KjGR9fztzbIdFhZcvPAA","tbWidth":"148","tbHeight":"111","unescapedUrl":"http://media.npr.org/assets/news/2010/04/11/panda-f8a7c9331bbac776e52b26feeccc53de959f46d1-s6-c10.jpg","url":"http://media.npr.org/assets/news/2010/04/11/panda-f8a7c9331bbac776e52b26feeccc53de959f46d1-s6-c10.jpg","visibleUrl":"www.npr.org","title":"Why The Animal Critic Gives The \u003cb\u003ePanda\u003c/b\u003e An F : NPR","titleNoFormatting":"Why The Animal Critic Gives The Panda An F : NPR","originalContextUrl":"http://www.npr.org/templates/story/story.php?storyId\u003d125773728","content":"A \u003cb\u003epanda\u003c/b\u003e. iStockphoto.com","contentNoFormatting":"A panda. iStockphoto.com","tbUrl":"http://t3.gstatic.com/images?q\u003dtbn:ANd9GcT3wJ6FzzTa01idfln9jm2pNKC8YJFAJGsMim0KjGR9fztzbIdFhZcvPAA"}],"cursor":{"resultCount":"428,000,000","pages":[{"start":"0","label":1},{"start":"4","label":2},{"start":"8","label":3},{"start":"12","label":4},{"start":"16","label":5},{"start":"20","label":6},{"start":"24","label":7},{"start":"28","label":8}],"estimatedResultCount":"428000000","currentPageIndex":0,"moreResultsUrl":"http://www.google.com/images?oe\u003dutf8\u0026ie\u003dutf8\u0026source\u003duds\u0026start\u003d0\u0026hl\u003den\u0026q\u003dpanda","searchResultTime":"0.24"}}, "responseDetails": null, "responseStatus": 200}

    The Result itself might seem confusing at first, but by filtering it with the following regex a much more clear list of results can be displayed.

    (\"http\\S+?jpg\")

    After applying this regex a list like the following can be extracted:

    As you can easily tell, not all URLs are valid, but there are 2 or 3 that could be used.
    What I am trying to do is extracting a list of "potential valid URLs" and then try to make labels with imageIcons extracted off the valid links.
    This is my code so far.
    Code:
    import java.awt.BorderLayout;
    
    
    public class browser extends JFrame {
    
    	private JPanel contentPane;
    	private JTextField textField;
    
    
    
    	/**
    	 * Create the frame.
    	 */
    	public browser() {
    		
    		setBounds(100, 100, 450, 300);
    		setVisible(true);
    		contentPane = new JPanel();
    		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    		setContentPane(contentPane);
    		contentPane.setLayout(null);
    		
    		textField = new JTextField();
    		textField.setBounds(6, 11, 390, 28);
    		contentPane.add(textField);
    		textField.setColumns(10);
    		mainFrame mOb = new mainFrame();
    		
    		JButton search = new JButton("");
    		
    		search.setIcon(new ImageIcon("C:\\Users\\Mihai\\Desktop\\search-icon.png"));
    		search.setBounds(397, 11, 31, 28);
    		contentPane.add(search);
    		
    		JScrollPane scrollPane = new JScrollPane();
    		scrollPane.setBounds(6, 51, 422, 205);
    		contentPane.add(scrollPane);
    		scrollPane.getViewport().setOpaque(false);
    		final JPanel editorPane = new JPanel();
    		scrollPane.setViewportView(editorPane);
    		editorPane.setOpaque(false);
    		editorPane.setBackground(new Color(0,0,0,0));

    		background.setBounds(0, 0, 434, 262);

    //I have deleted one of the exceptions as i should limit myself to 20000 characters per post, but it's essentially the same as the other null-pointers

    The first line is the raw query, the nest 6 are "potentially valid URLs" and the code following is a series of exceptions. You can observe that The first exception refers to a malformed URL exception, while all the others refer to null-pointer exceptions.

    I am curious and seeking help about the following:




    •Why is the sequence of exceptions like it is?
    •Can you help me design a better RegEx to grab valid URLs?
    •Is there a better, and not very complicated way of doing the same thing(making an image query) without all this trouble?



    Thank you so much for your time!
