Cannot attach to java applet

[gen_www]

I am running an applet in Internet Explorer using <Object> tag and
trying to attach to it using Netbeans IDE. However Netbeans is not able
to attach to the applet. However I can use Netbeans to attach to
Weblogic server.

a) Have read various documents on various websites including
http://java.sun.com/products/plugin/...debugging.html
b) My classes are compiled with -g option. (Attaching to VM fails, so I
dont think that's an issue at this stage)

I will appreciate any help or comments.
Thanks

Here are the settings and parameters:

Java plugin version = 1.3.1_02

(have tried various versions for both)
1)
Java runtime parameters in Java plugin control panel.
-Djava.compiler= NONE -Xnoagent -Xdebug
-Xrunjdwp:transp ort=dt_shmem,ad dress=2502,serv er=y,suspend=n

2) <OBJECT> tag:
OBJECT name="ABC" classid="clsid: CAFEEFAC-0013-0001-0002-ABCDEFFEDCBB"
width="10" height="10" align="baseline "

codebase="http://<%=request.getS erverName()%>:< %=request.getSe rverPort()%>/downloads/jre_plugin.cab# Version=1,3,1,0 2">

<PARAM NAME="code" VALUE="com.mypa ckage.myclass.c lass">
