Assigning java function output to VXML variable in GVP 7.6

deadmeat · July 16, 2012, 7:08am

Hello everyone! Would be very grateful if someone could help me. The goal is to insert some java code into the jsp page, and assign the output to VXML Variable. Here is the example:


<?xml version="1.0" encoding="UTF-8"?><%@page contentType="text/xml" pageEncoding="UTF-8" buffer="none"%>
<vxml xmlns="http://www.w3.org/2001/vxml"  xml:lang="ru-RU" version="2.0" application="root.jsp">
    <%@page import="java.util.Date, java.sql.Timestamp"%>
    <%@taglib prefix="bakcellivr" uri="/WEB-INF/tlds/bakcellivr"%>
    <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
    <%@taglib prefix="ad" tagdir="/WEB-INF/tags/attach_data"%>
    <%@taglib prefix="debug" uri="/WEB-INF/tlds/debug"%>

<%
java.sql.Timestamp timestamp = new Timestamp(System.currentTimeMillis());
pageContext.setAttribute("timestamp ", timestamp);
System.out.println(timestamp);
%>

    <form>
        <!-- Get the attach data -->
        <ad:get name="attach_data">

But unfortunately the value of IVRTenter variable remains empty

Hi,

Have you tried following?

<assign name="OBMESSAGE" expr="${bakcellivr:getIvrOption('obmessage')}"/>
<assign name="IVRTenter" value="<%=timestamp%>"/>

Does the START.jsp page open from browser? Can you send me generated VXML code?

No, browser can not open the page.

Well, I noticed that all efforts to assign value to VXML variable using are ending with server error. Must be the specifications of VXML it can only accept static values in value=“” expression, not the server code like <% %>
That’s why I used <c:set > instead. But it doesn’t put any value to variable, it remains empty. This construction <%
java.sql.Timestamp timestamp = new Timestamp(System.currentTimeMillis());
pageContext.setAttribute("timestamp ", timestamp);
System.out.println(timestamp);
%> is working fine, I see it in catalina.out (the println function) the problem is to assign this output to VXML variable. Somebody has any thoughts on that ?

Rene · July 18, 2012, 12:18pm

Hi deadmeat,

Construction <%= … %> is never passed to VoiceXML interpreter as it is processed by your Java server.

Your problem is related to the fact that your Java server doesn’t know ‘Timestamp’ type (class). Please fix this error first.

An error occurred at line: 10 in the jsp file: /vxml/start.jsp Timestamp cannot be resolved to a type 7: <%@taglib prefix="debug" uri="/WEB-INF/tlds/debug"%> 8: 9: <% 10: java.sql.Timestamp timestamp = new Timestamp(System.currentTimeMillis()); 11: pageContext.setAttribute("timestamp ", timestamp); 12: System.out.println(timestamp); 13: %>

By the way, when I was getting the timestamp like this: 2012-07-18 17:08:00.563 PopGateway was throwing errors, that this value cannot be assigned to a variable. Maybe some VXML restrictions, I don’t know.
