Echo Web Framework

I am trying to get the BrowserOpenWindowCommand to open a new browser with an HTML source from within my application. The html is under the webapp folder and this works perfectly well in Mozilla Firefox, but not in Microsoft IE. Any suggestions? My code is posted below.

Thanks!

    HttpServletRequest req = app.getCurrentRequest();

    String sep = "/";
    String serverName  = req.getServerName();
    int    serverPort  = req.getServerPort();
    String contextPath = req.getContextPath();
            
    StringBuilder sbURI = new StringBuilder()
    .append("http:")
    .append(sep)
    .append(sep)
    .append(serverName)
    .append(":")
    .append(serverPort)
    .append(contextPath)
    .append(sep)
    .append("help")
    .append(sep)
    .append("Scenario2.htm")
;
            
    StringBuilder sb= new StringBuilder()
    .append("width=800")
    .append(",height=600")
    .append(",resizable=yes")
    .append(",scrollbars=yes")
;

    Command oComm = new BrowserOpenWindowCommand(sbURI.toString(),"New"",sb.toString());
    app.enqueueCommand(oComm);
