Problem description : 
With Mozilla browser when I try to invoke the JSObjects call method 
it throws following exception 

SEVERE: Stack Trace - netscape.javascript.JSException

Following is what I have done in my applet. 
I have passed a DOM html page in sText as shown below to CallJavaScript 

String sText = "<!DOCTYPE HTML PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'xhtml1-transitional.dtd'><html mlns:ims0='http://www.imsproject.org/xsd/imscp_rootv1p1p2'><head><META http-equiv='Content-Type' content='text/html; charset=UTF-8'><title>Test Page </title><script type='text/javascript' langauge='javascript'>\t\t\t\t\t\tfunction callMe(sText){\t\t\t\t\t\t\talert(" in CallMe");\t\t\t\t\t\t}\t\t\t\t\t\t\tfunction callMeNS(sText) {\t\t\t\t\t\t\talert("in CallMeNS");\t\t\t\t\t\t}/script></head><body><table><tr><td>WELCOME</td></tr></table></body></html>"; 

then I constructed a String array to be passed as second argument to the CallJavaScript function 

String sParam[] = {"window.top.frames[\"frmTest\"].callMe(\"" + sText + "\");"}; 

this is my call javascript function call 
CallJavaScript("callMe", sParam); 

Below is the CallJavaScript function which throws an exception 

/** 
* Note : This method calls javascript function on the client side. 
* @param functionName - JavaScript function to be called 
* @param parameters - List of Parameters to the JavaScript Function 
*/ 
public void CallJavaScript(String functionName, String parameters []) { 
this.functionName = functionName; 
this.parameters = parameters; 
try { 
if (oSession.sGetValue("browser").toString().equals("IE")) { 
JSObject win = JSObject.getWindow(this); 
win.call(functionName, parameters); 
} else { 
JSObject win = JSObject.getWindow(this); 
win.call("callMeNS", parameters); }} 
catch (netscape.javascript.JSException e) { 
e.printStackTrace(); } 
catch (Exception excep) { 
excep.printStackTrace(); } } } 

Actually I am trying to pass a html snippet to a Javascript function via JSObject. 
If the browser is FireFox then it throws an exception. 
It shows some errors pertaning to the parameterlist passed as second argument to JSObject's call() function. 

Here in the code, the second argument "parameters" produces some JavaScript errors in the browser. 
win.call("callMeNS", parameters); 

My html page is divided in 2 frames,I am trying to invoke a function in one of those frames. 
I can call the function by passing null as argument2 as fuollows 
win.call("callMeNS", null); 
but it gives me exception for the argument list I pass.

Firefox code moved from custom Liveconnect code to the NPAPI/NPRuntime bridge a while back. Mass-closing the bugs in the liveconnect component which are likely invalid. If you believe that this bug is still relevant to modern versions of Firefox, please reopen it and move it the "Core" product, component "Plug-Ins".
