Developing swing GUI using XML

hi
I must develop a GUI using swing by parsing XML documents.How to render the swing objects at run time, after parsing the XML document.I must know the process of creating the swing containers,components from XML document. Some open sources are available for the purpose but i must create a framework for our own purpose, so must know the process involved.
kindly provide me any links or tutorial for the same.
with Regards,
A.Rajesh

hey thanks for the help...i saw these tools but my problem will not be solved by these as the diagram i need to generate from XML is a class diagram. The components of class diagram cannot be made using swings...eg arrow,rectangle,aggregation symbol etc....

Build GUI using XML

Hi,
I am interested in learning more about building a UI using XML...any suggestions? I have looked at SwiXml ....just looking for more. If you have used one/or more of them before, let me know what your opinions are to.
Thanks!

I know there are several of these things out there. The one I've tried was Thinlets. It looks good and is very lightweight. It's easy to get something running quickly, but you'll eventually run into limitations since the components are by far not as rich and flexible as swing. I still think it's great for what it does.
If you're going to do a google search, I think one of the key words to use is XUL.

GUI in XML

I am interested in writing some Swing GUI's in XML, and i know there are a couple of programs/libraries that do this (such as UIML), but can you please recommend me some good one? Anybody has any experience with this?
Thanks in advance,
Victor.

There's a few levels of this question I'm sure. You could write Swing GUIs in XML using the XMLEncoder/XMLDecoder framework to effectively write Swing code.
Then again, you could write XUL, which wouldn't be tied to Swing, but you could use a Swing implementation of it.

XML = Swing GUI, which framework would you recommend?

Hi,
I'm looking for a framework that translates an XML description to a Swing GUI.
There're a lot available, e.g. gui4J, swixml, Thinlet, XUL, XULUX, Jelly, SwingML
Can you recommend one?
Are there any drawbacks I should be aware of from using such a framework? How about performance?
Many thanks

Hello,
The SwingAppKit is provided with the source :

Develop UI displaying Tree Using XML

Hi Techies,
I am in the process of developing a UI that should show a tree (not like folder structure).
The tree should start from root node and that may contain n-children and similarly n-levels.
Currently I have a XML file that has the information about the Parent Children relationships.
I wanted to know how to parse this XML and put in the form of UI, the bottom line is, "Developing UI by using XMLfile in Java Code".
I hope I am clear.
Waiting for the reply(ies).
Thanks
- Vikas DK

have two tier architecture... One is View and another one is model&controller
For view use JTree to construct root and show thier children in the form of nodes.
In the model part,use DOM parser to read the XML and store it as a document. From the document read the elements and populate the tree nodes in the view part....
This is a highlevel approach.. ... do u expect any specific implementation details

Loading large files in Java Swing GUI

Hello Everyone!
I am trying to load large files(more then 70 MB of xml text) in a Java Swing GUI. I tried several approaches,
1)Byte based loading whith a loop similar to
pane.setText("");
             InputStream file_reader = new BufferedInputStream(new FileInputStream
                       (file));
             int BUFFER_SIZE = 4096;
             byte[] buffer = new byte[BUFFER_SIZE];
             int bytesRead;
             String line;
             while ((bytesRead = file_reader.read(buffer, 0, BUFFER_SIZE)) != -1)
                  line = new String(buffer, 0, bytesRead);
                  pane.append(line);
             }But this is gives me unacceptable response times for large files and runs out of Java Heap memory.
2) I read in several places that I could load only small chunks of the file at a time and when the user scrolls upwards or downwards the next/previous chunk is loaded , to achieve this I am guessing extensive manipulation for the ScrollBar in the JScrollPane will be needed or adding an external JScrollBar perhaps? Can anyone provide sample code for that approach? (Putting in mind that I am writting code for an editor so I will be needing to interact via clicks and mouse wheel roatation and keyboard buttons and so on...)
If anyone can help me, post sample code or point me to useful links that deal with this issue or with writting code for editors in general I would be very grateful.
Thank you in advance.

Hi,
I'm replying to your question from another thread.
To handle large files I used the new IO libary. I'm trying to remember off the top of my head but the classes involved were the RandomAccessFile, FileChannel and MappedByteBuffer. The MappedByteBuffer was the best way for me to read and write to the file.
When opening the file I had to scan through the contents of the file using a swing worker thread and progress monitor. Whilst doing this I indexed the file into managable chunks. I also created a cache to further optimise file access.
In all it worked really well and I was suprised by the performance of the new IO libraries. I remember loading 1GB files and whilst having to wait a few seconds to perform the indexing you wouldn't know that the data for the JList was being retrieved from a file whilst the application was running.
Good Luck,
Martin.

Gui xalan xml

I am trying to program a java swing gui with one button that will
transform old.xml to new.xml using transform.xsl using xalan
but the compiler gives an error message:
Transform2.java:53: unreported exception javax.xml.transform.TransformerException; must be caught or declared to be thrown
transformation("hamlet.xml","transformation1.xsl","hamletnew.xml"
anyone know the solution of this problem
this is the complete code:
//using apache xalan to transform old.xml with tranform.xsl into new.xml
//with java swing gui
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.FileNotFoundException;

button.addActionListener(eventclick);
frame.getContentPane().setLayout(new FlowLayout());
frame.getContentPane().add(button);
frame.pack();
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
private static void transformation(String inputfile,String xslfile,String outputfile)throws TransformerException, TransformerConfigurationException,FileNotFoundException, IOException
// Use the static TransformerFactory.newInstance() method to instantiate
// a TransformerFactory. The javax.xml.transform.TransformerFactory
// system property setting determines the actual class to instantiate --
// org.apache.xalan.transformer.TransformerImpl.
TransformerFactory tFactory = TransformerFactory.newInstance();
// Use the TransformerFactory to instantiate a Transformer that will work with
// the stylesheet you specify. This method call also processes the stylesheet
// into a compiled Templates object.
Transformer transformer = tFactory.newTransformer(new StreamSource(xslfile));
// Use the Transformer to apply the associated Templates object to an XML document
// (foo.xml) and write the output to a file (foo.out).
transformer.transform(new StreamSource(inputfile), new StreamResult(new FileOutputStream(outputfile)));

Function
private static void transformation(String inputfile,String xslfile,String outputfile)throws TransformerException, TransformerConfigurationException,FileNotFoundException, IOExceptionStates that that function might throw an on of the exceptions mentioned.. to do this you have to have
try{
   //the code that this function should do...
catch(Exception e)
    // if doing previous stuff fails... this will be executed.
    // here do the throwing..
    throw new IOException (this);
}also the main function propably should not throw exceptions..

Recommended Tool for devloping Swing GUI's?

Hello everyone.
I was wondering what a good tool kit was for building swing gui's?
I heard NetBean was one, any others you recommend?
Currently I use Rational Software Architect to do all my java coding but I don't see any options in this IDE for creating drag and drop GUI development.
Thanks!

You have 2 very different answers to consider. Before making your final decision, I'd ask yourself, which of the two responders is a Swing expert and which isn't. That should put a whole lot of added weight to one of the recs. Just my two scheckel's worth.

Embedding applets in Swing GUI?

I'm pretty new to developing with Swing.
I want to know what I would need to do in order to embed an applet inside a Swing GUI (if this is possible). I've looked around, but can't seem to find anything with an answer to my question.
Any help would be greatly appreciated.

import javax.swing.*;
import java.applet.Applet;
import java.awt.Label;
/** Simplistic example of putting an Applet in a JFrame. */
public class AppletInSwingGui extends Applet {
public void init() {
    add( new Label("I am an applet!") );
public static void main(String[] args) {
    final AppletInSwingGui applet = new AppletInSwingGui();
    // very important!
    applet.init();
    Runnable r = new Runnable() {
      public void run() {
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add( applet );
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    SwingUtilities.invokeLater(r);
}Note that if the applet uses the functionality of the AppletContext, the programmer needs to implement it. Some of the Applet specific methods (like getDocumentBase() and getCodeBase()) are also a bit tricky.

Develop Java GUI to interact with MS Access

I am doing a Java course and got this assignment to develop a GUI application using MS Access to get data and to update information for an automated library system. I would realy like some help with integrating the GUI with Access. I started Java a few weeks ago from scratch and would appreciate all the help I could get. I really have fallen in love with Java and I think that it is a really great programming language to use. I really would love to become a Java expert some day.

Take a look at the Java tutorials page. Theres a tutorial on "Creating a GUI Using JFC/Swing" and "JDBC Database Access":

Launch swing GUI on MAC

I developed a swing GUI recently. It works perfectly under Linux, Unix, Windows, but the users of the GUI will run it on MAC. I haven't any idea about MAC. Does anybody give me some suggestions about
How to launch my application on mac?
Are there any strategies or tricks for running a swing GUI on MAC?
How can I put a shortcut or icon on user's desktop of mac so that when the user click it, my swing gui can open immediately?
Thank a million in advance

Well... on Mac OS X, it is very easy. You just put your application in a .jar file. On Mac OS X, jar files are automatically run when double clicked. You won't have to worry about downloading a jdk, because it is integrated with the system.
Mac OS 9 however only made it to jdk version 1.1.8, and you will have to use the Bindary program to make it runnable. Strongly suggest users to upgrade to Mac OS X, because on 9, it is a pain...
With pleasure,
Wannes.

Multi-Client TCP Server /w Swing GUI

Hi everybody,
i have to develop a Multi-Client TCP Server with a Swing GUI. The GUI mainly consists of a JTable which shows various trace messages from processes running on other computers. As the data needs to be filtered i�m using a custom TableModel derived from AbstractTableModel. I�m creating a new thread for every client that connects as shown in http://java.sun.com/developer/onlineTraining/Programming/BasicJava2/socket.html
Now every client thread reads data from its TCP connection and puts it into the JTable by calling the method addRow of the model. But i�m getting strange NullPointerExceptions and IndexOutOfBoundExceptions when data arrives (i�m using ArrayList in the model). These exceptions never show in a single-threaded Swing app (i�ve tested this already, so i don�t think it�s a bug in my model), so i think this is a problem with Swing�s thread unsafety? Do you have any hints on how to get away with it? Also general design tips for a Multi-Client TCP Server /w Swing GUI are greatly appreciated.
Thanks in advance!
Best regards,
Disposable_Hero

Of course, but i don�t think it is the model (as said before it works fine in a single thread swing app)
