    Default My code was showing picture but now it's not!!!!!

    I had a Person class (I mentioned it earlier in other threads) and I had a class called TablePanel and a Tester class. It showed my picture.

     
    package addressbook.util;

    When I tried to make it more sophisticated and get toward the final project, I added the following classes. (Also, that main class above was just a test one. The one below is actually the project main class.)

    (Note: I don't think PersonSearcher is the problem. Though, maybe it's my get() method.)

    {
     
     
     
       public static void main(String[] args)
       {
     
          new JAddressFrame();
     
     
     
     
       }
     
     
    }


    Now, when I run it, it doesn't show the picture, at least, not until I upload a new one. But, as it would really ruin part of the point of what I'm trying, I need the picture to show up right away. My default picture, which is in the same spot, pretty much, as the code, is

    noPic.jpg


    When I run it now, however, it won't show up.

    However, once I hit "upload" and upload, it'll show the picture all of a sudden. So I know that my structure has to been working right with my CellRenderer subclass.

    I can say that it's not in the part where I'm formatting the menus and probably couldn't be in any but the setPicture() part of the Person class. (Though I doubt it as it worked there earlier and works when I upload.)

    The PersonSearcher doesn't appear to be it.

    It likely could be because of the fact that I don't have canonical path for the default image but the upload has it.

    It may well be a glitch in the way I'm using my XML Parser (the PersonXMLHandler or whatever it was called).

    I doubt it is anything in the JAddressBook or the testing class for the project. I have no clue where and can't pair down the code in there too much further or it wouldn't compile for you.

    I'm just baffled as to what could have happened to make it work with just Person, TablePanel, and that test class at the top, but not work when I add PersonSearcher, PersonXMLHandler, JAddressBook, and the project test class. And why, if it won't work initially, will it show suddenly when I use the upload button? (Somehow, I feel that the canonical path may be an issue. The other likely culprit is the XML parser class.)

    I'm just so lost as to what's going wrong.

    That's a ton of code to ask strangers on the internet to debug for you, for free, in their spare time. If you want better help faster, I suggest creating an SSCCE that demonstrates your problem in as few lines as possible.

    Now things are even stranger, when I tried to fix it. I got it to create the canonical path when it reads the xml file (if the xml file doesn't exist). If that happens, then it adds twice to my JTabbedPane, and the second tab, though the same data as the first, shows the picture.

    However, once the xml file exists, in future runs, it'll only show one tab (which is good) but not the image (which is bad).

    I can post classes one by one and see if the glitch is in them. I am going to check the PersonXMLHandler class first as I am still learning about the XML reading classes and may easily have made a mistake as I only used tutorials.

    ----Update-----
    I have tried altering the XML file and put data in most of the columns to see if that was it and it reads them in, but the picture still isn't displaying. I have to go somewhere right now

    I cannot really make a SSCCE as I don't know where the problem is happening at.

    I can get it to work if I load a new Person but not if I load it from the xml. I think it's a glitch either in the parser or the Person class. I think it wasn't working if the image was already defined. The non-default Person constructor could be the issue.

    It's likely in this class. (Note, I might want to get rid of the getCanonicalPath() stuff as that makes it less transferable if stuff is moved to another computer. It was just using it mainly to see if it fixes the problem but it's not.)

    It's probably in the second constructor or something. But I can't see what's going wrong.

    Also, I am trying to make it work here too but it's not working still:

     protected class ImageRenderer extends DefaultTableCellRenderer
       {
     
          @Override
          public Component getTableCellRendererComponent(JTable table,Object value, boolean isSelected,boolean hasFocus, int row, int column)
          {
             JLabel label = new JLabel();
     
             if (value!=null) {
                label.setHorizontalAlignment(JLabel.CENTER);
     
     
                java.io.File f = new java.io.File((String) value);
     
                String fullPath = null;
     
                try
                {
                   fullPath = f.getCanonicalPath();
                }
     
                catch(java.io.IOException ioe)
                {
     
     
     
                }
     
     
                ImageIcon icon = new ImageIcon(fullPath);
     
     
                java.awt.Image image = icon.getImage().getScaledInstance(200, 200, java.awt.Image.SCALE_SMOOTH);
                icon.setImage(image);
     
                label.setIcon(icon);
             }
     
     
             return label;

    Default Re: My code was showing picture but now it's not!!!!!

    Ok, it's NOT the non-default constructor of Person either as my earlier test class was able to show the picture successfully with it. I tried using the value of the picture attribute read in by my XMLParser and tried

    System.out.println((new File(pictureValue).exists());

    It printed out "false".

    I tried creating a new JFrame and setting the content pane to be the picture attribute read in in a new ImageIcon, which didn't show up there either.

    I tried setting the full path to see if it just didn't like that I was just using ./picFile.jpg as the spot for it, still didn't work.

    I told it to print out what it's reading and it printed what was in the XML file so I know it's reading it. I just have no clue whatsoever as to why it wouldn't display it.

    Also, it DOES display it if I, once I have the stuff read in, albeit without the picture, click the upload button and get a picture that way.

    I uploaded the same image file that it couldn't somehow display and that, when I created a File object with the String, it said that the file didn't exist, and it worked like it should.

    I cannot seem to get any closer to finding what IS causing it, but rather, only ruling out what likely ISN'T the reason for it not showing.


    Here is the XML Parser class. The error is very likely in here, though, I have no idea where it could be.

          try {
             SAXParser parser = factory.newSAXParser();
             parser.parse(xmlFile, this);
          } 
          catch (ParserConfigurationException e) {
             System.out.println("ParserConfig error");
          } 
          catch (SAXException e) {
             System.out.println("SAXException : xml not well formed");
          } 
          catch (java.io.IOException e) {
             System.out.println("IO error");
          }
       }
     
     
    }


    The XML file is:

    <addressbook>
    <person>
    <name> Barack Obama </name>
    <address> 1600 Pennsylvania Avenue </address>
    <city> Washington D.C. </city>
    <zip> 12345 </zip>
    <home> 123-456-7890 </home>
    <cell> 098-765-4321 </cell>
    <email> ihateAmerica@whitehouse.gov </email>
    <picture> ./noPic.jpg </picture>
    </person>
    <person>
    <name> Paul Revere </name>
    <address> 1234 Lexington St. </address>
    <city> New York </city>
    <zip> 83019 </zip>
    <home> </home>
    <cell> 223-315-8312 </cell>
    <email> hero@revolution.com</email>
    <picture> ./noPic.jpg </picture>
    </person>
    </addressbook>


    The picture, noPic.jpg is in the main directory of the folder of the project. Normally, that's where my code looks to find images in other projects and it can find it there. I know it can find it where it's at too as it did for when I added a new person using the add person button the picture with the picture string ./noPic.jpg and it worked and when I upload a picture from that directory.

    noPic.jpg


    I am nearly able to get a lot of the address book done, and can probably do the write to the xml to make sure that it can use the xml file to get the data in the future. However, this picture displaying problem is an issue that is holding me up.


    -----Update------
    I found that it was, in fact, because of spaces in my test xml file that were making the image files invalid. I was right to suspect that the problem was coming form the xml reader. However, the issue turned out to be in the xml file. I think the issue is solved now.
