Calling a java function from javascript

Hi all!
I have created a java applet and wish to access one of its methods in Javascript, so I am using the following HTML code:
function sendMessage() { window.document.formName.variablePassedIn.value = window.document.appletName.readReturnValue(); } .... <applet name="appletName" code="Example.class" height=500 width=500 VIEWASTEXT> <param name="message" value="<%=number%>"> <param name="phonenumber" value="<%=number%>"> <param name="userID" value="<%=UID%>"> <param name="password" value="<%=UPW%>"> <param name="MAYSCRIPT" value="true"> <param name="scriptable" value="true"> </APPLET> <form name="formName"> <input type = "hidden" name="variablePassedIn"> </form> <SCRIPT language="JavaScript"> sendMessage() alert(window.document.formName.variablePassedInvalue); alert("Hello"); </script>
The java code is as follows:
public static String readReturnValue() { String returnValue= new String("100"); return returnValue; }
There doesn't seem to be a problem running the applet, but when I call the javascript function I get the following error message:
'Object doesn't support this property or method'
Does anyone know why this is? And how I remedy it?
Thanks and regards,
Sean

Hi,
Are you getting error in function sendMessage()?
To confirm this put alert statements before and after
window.document.formName.variablePassedIn.value = window.document.appletName.readReturnValue();
Also change
alert(window.document.formName.variablePassedInvalue);
to
alert(window.document.formName.variablePassedInvalue.value);
