when I am trying to define my applet as Main class
<JWrapper>
    <!-- The name of the app bundle -->
    <BundleName>MemoryMap</BundleName>
    <!-- The specification for one app within the bundle -->
    <App>
      <Name>MemoryMap</Name>
      <LogoPNG>sampleapp/logo.png</LogoPNG>
     <MainClass>com.example.SampleApplet</MainClass>
    </App>
getting below exception Caused by: java.lang.NoSuchMethodException: com.example.SampleApplet.main([Ljava.lang.String;)
Not sure if we cannot define applet class as main class , does that mean Jwrapper could not bundle Applet?
Please suggest..
                        
Its not possible to specify an Applet or JApplet as the main class in a JWrapper application however converting an Applet or JApplet to a standalone class is usually a simple process of just creating a JFrame and embedding the applet UI into it, then specifying a main method to launch the JFrame.
Here's an example:
