Hi everyone,
Iam calling an Applet from JSP,while Applet is getting loaded, Iam getting an exception message, I tried to debug this by putting some debud statements inside the Applet's init() method, but it is not printing any debug statements, the Applet has to load two images in the webpage it is loading the images but it is not printing the debug statements, and these two images inside the Applet acts like buttons to call the Servlets, but when I click on the images they are not calling the Servlets.
Iam posting here the code for JSP,Applet's init() method and WAS log.

<jsp lugin
type="applet"
code="com.sas.edis.viewers.EDISCaptureSnapShotApplet.class"
codebase="/EDIS/assets/graph/"
jreversion="1.4"
width="80"
height="100"
name = "OutputOptionsObject"
iepluginurl ="https://edistest.intra.daimlerchrysler.com:8000/unprotected/edis/j2re-1_4_2_07-windows-i586-p.exe">;

<jsp arams>
<jsp aram name="java_archive" value="EDISGraphApplet.jar"/>
<jsp aram name="java_type" value="application/x-java-applet;version=1.4"/>
<jsp aram name= "fileName" value ="<%=elements.getImageName() %>" />
<jsp aram name="fullImageLocation" value="<%=elements.getFullImageLocation()%>"/>
<jsp aram name="SASImageLocation" value="<%=elements.getSASImageLocation()%>"/>
<jsp aram name="applicationURL" value="<%=elements.getApplicationURL()%>"/>
</jsp arams>

init() method code::::

public void init()
{
System.out.println("begining of the init() method:");
log.error("inside init() method");

this.fileName = getParameter("fileName");
this.applicationURL = getParameter("applicationURL");
this.fullImageLocation = getParameter("fullImageLocation");
this.SASImageLocation = getParameter("SASImageLocation");


System.out.println("middle of the init() method:");

String imageJPG = new String("../../images/imagedit.gif");
String imagePDF = new String("../../images/filepdf.gif");

ImageIcon JPGicon = new ImageIcon(getURL(imageJPG));
ImageIcon PDFicon = new ImageIcon(getURL(imagePDF));

System.out.println("Inside the Applet's init method");


JPanel onePanel = new JPanel();

btnJPG = new JButton(JPGicon);
btnJPG.setToolTipText("Output to JPG");
btnJPG.setBackground(Color.white);
btnJPG.addActionListener(this);

btnPDF = new JButton(PDFicon);
btnPDF.setToolTipText("Output to PDF");
btnPDF.setBackground(Color.white);
btnPDF.addActionListener(this);

log.error("end of init() method");
System.out.println("end of the init() method:");

Container contentPane = getContentPane();
contentPane.setLayout(new GridLayout());
contentPane.setBackground(Color.white);

onePanel.add(btnJPG);
onePanel.add(btnPDF);
onePanel.setBackground(Color.white);

contentPane.add(onePanel);
}
