Error: java.lang.NoClassDefFoundError: Chase (wrong name: pong/Chase)
<p>I have created an applet program using Eclipse IDE. Now im creating .html file as below:</p>

<pre><code>&lt;html&gt;
&lt;APPLET CODE="Chase.class" width=500 height=400&gt;
&lt;/APPLET&gt;
&lt;/html&gt;
</code></pre>

<p>When Im executing this file the error im getting is:</p>

<pre><code>java.lang.NoClassDefFoundError: Chase (wrong name: pong/Chase)

</code></pre>

<p>In Eclipse IDE is have created new project and packaged the program into "pong" folder.</p>

<p>Can anybody explain why this error is occuring?</p>

<p>Edit:</p>

<p>Adding few Chase.java code lines, for clarification. It is simple applet:</p>

<pre><code>package pong;


import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.Random;



public class Chase extends Applet implements Runnable
{ ...  }
</code></pre>
