New Line in Javascript Alert

I'm writing out some javascript code in my
servlet, and if I put a "\n" into my code -
I get a undetermined string error.  If I take
it out, it works fine.

Here's sample code:

 public void doGet (HttpServletRequest request, HttpServletResponse response)
                                                                      throws ServletException, IOException{
             PrintWriter      out;         
       // set content type and other response header fields first
             response.setContentType("text/html");
           // then write the data of the response
       out = response.getWriter();

             // html text ........................

            out.println("<SCRIPT language=\"JavaScript\">");
            out.println("<!--");
            out.println("function Warning(war, war1){");
            out.println("if(war == \"\" || war1 == -1) {");
     ??? out.println("alert(\"1. Save As \n 2.Open \" );");
            out.println("return (false);");
       out.println("}");
       out.println("else {");
      out.println("return (true);");
      out.println("}  }");
          out.println("//-->");
      out.println("</SCRIPT>");

            // html text.........................
       }

out.println("alert(\"1. Save As \\n 2.Open \" );");

You must escape the backslash with a backslash, otherwise the newline character is written to the alert statement, instead of the text that the alert is supposed to display.  For example, your code above would output this:

 alert("1. Save As
 2. Open");


instead of:

 alert("1. Save As \n2. Open");
