javascript - Java Applet is undefined -

-

i have jzebra applet need client side ticket printing.

this applets html definition:

<applet id="jzebra" name="jzebra" code="jzebra.printapplet.class" archive="../../../../../../web/org.openbravo.howtos/lib/jzebra.jar"    width="10px" height="10px">

the function call in form button this:

function printdocument() {    var applet = document.jzebra;   var frm = document.frmmain;   var url = frm.elements["inpftpobdir"].value;   var file ="0.txt";   var archivo = url + "/" + file;   if (applet != null) {   var printname = frm.elements["inpprintername"].value;   var indice = frm.inpprinterselected.selectedindex;   var printselected = frm.inpprinterselected.options[indice].text;         alert(printname);         alert(printselected);         if(printselected == ""){            // printname = "zebra"            //alert('default : ' + printname);            applet.findprinter(printname);            monitorfinding();         } else {            //alert('selected : ' + printselected);            applet.findprinter(printname);            monitorfinding();         }         alert('file : ' + archivo);         // applet.findprinter(printname);         applet.appendfile(archivo);          // send characters/raw commands printer         applet.print();           alert('the document sent printer.');    } }

i checked console , there definition of applet, when reaches applet.findprinter(printname), explodes because applet.findprinter not function.

has faced struggle before? have seen there little gray square in top left corner of page. when hover on it, displays "undefined".

i came complex solution, having use jnlp. post code later references, if else find similar problems.
