Calling Applet method using javascript on Netscape

[pavan in]

Does anyone know how to call an applet method on netscape. I am using OBJECT/EMBED tags. It works fine for IE but, gives error on netscape. Error is 'Not a method'
OBJECT classid="clsid:CAFEEFAC-0014-0000-0000-ABCDEFFEDCBA"
WIDTH = "100%" HEIGHT = "99%" NAME = "treeApplet" codebase="j2re-1_4_0-win.exe">
<PARAM NAME = CODE VALUE = "com.att.uam.ui.treehierarchy.applet.EuamTreeApplet" >
<PARAM NAME = ARCHIVE VALUE = "appleteuam.jar" >
<PARAM NAME = NAME VALUE = "treeApplet" >
<PARAM NAME = MAYSCRIPT VALUE = true >
<PARAM NAME = type VALUE = "application/x-java-applet;jpi-version=1.4">
<PARAM NAME = scriptable VALUE = "true">
<COMMENT>
<EMBED
type="application/x-java-applet;jpi-version=1.4"
CODE = "com.att.uam.ui.treehierarchy.applet.EuamTreeApplet"
ARCHIVE = "appleteuam.jar"
NAME = "treeApplet"
WIDTH = "100%"
HEIGHT = "99%"
MAYSCRIPT = true
scriptable = "true"
pluginspage = "AppletPluginDownload.html"

Dear Pavan,
Where in your code calling the javascript method?
Am also using the applet in netscape and calling the applet method using the javascript.

Please send the full code to solve your problem.
