    Smile Netbeans IDE 7.4 does not recognize Swing apps, it is looking for main method instead...

    Hello there,

    As the title state's, my IDE doesn't seem to recognize that my program is a Swing app.
    I get the following error message when I run the app: "jtabledemo.JTableDemo class wasn't found in JTableDemo project."
    It compiles successfully though.


    Here is the code verbatim:


    package jtableDemo;

    // Demonstrate JTable.
    import java.awt.*;
    import javax.swing.*;

    /*
    <applet code="JTableDemo" width=400 height=200>
    </applet>
    */

    public class JTableDemo extends JApplet {
    /**
    */
    public void init() {
    try {
    SwingUtilities.invokeAndWait(
    new Runnable() {
    public void run() {
    makeGUI();
    } // run()
    } // Runnable()
    ); // invokeAndWait()

    // end of try block
    } catch (Exception exc) {
    System.out.println("Can't create because of " + exc);
    }
    } // end of init() method scope


    private void makeGUI() {

    // Initialize column headings.
    String[] colHeads = {"Name", "Telephone", "ID#" };

    // Initialize data
    Object [][] data = {
    {"Gail", "345-5678", "865"},
    {"Ken", "654-7890", "555"},
    {"Viviane", "7566", "587"},
    {"Melanie", "7345" ,"922"},
    {"Anne", "333-4567" ,"333"},
    {"John", "222-5656" ,"314"},
    {"Matt", "456-6655" ,"217"},
    {"Claire", "6741" ,"444"},
    {"Erwin", "444-9023" ,"519"},
    {"Ellen", "667-1134" ,"532"},
    {"Jennifer", "999-5689" ,"112"},
    {"Ed", "345-5544" ,"133"},
    {"Helena", "334-6790" ,"145"}
    }; //end brace of array variable: data

    //Create the table
    JTable table = new JTable(data, colHeads); // pass the two arrays as arguments to constructor

    // Add the table to a scroll pane...thus making the table scrollable...
    JScrollPane jsp = new JScrollPane(table);

    // Add the scroll pane to the content pane
    add(jsp);

    } // end of makeGUI() scope
    } // class scope

    Any help is greatly appreciated!
    Thanks in advance.

    Welcome to the forum! Please read this topic to learn how to post your code correctly and other useful info for newcomers.

    Your error has nothing to do with Netbeans or recognizing your code as a Swing app. It's all about the capitalization of your package name.
