You can use a trial account to send a limited number of free messages for testing.\n\nThese quickstarts can be run using any server which can run Java Servlets. For these examples, we've used [Jetty](https://eclipse.org/jetty/) and jsp to provide a UI to view the receipts.\n\n1. Create a new Dynamic Website project\n2. Add the following libraries to the project\n * commons-logging-1.2.jar\n * httpasyncclient-4.1.1.jar\n * httpclient-4.5.1.jar\n * httpcore-4.4.4.jar\n * httpcore-nio-4.4.4.jar\n * servlet-api-3.0.jar\n * javax.servlet.jsp.jstl-1.2.0.v201105211821.jar\n\nCreate a file called Receipt.java to represent the incoming data\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"package com.dynmark;\\n\\nimport java.util.Date;\\n\\npublic class Receipt {\\n\\tprivate Date date;\\n\\tprivate String recipient;\\n\\tprivate int statusId;\\n\\tprivate String statusDescription;\\n\\tprivate String clientRef;\\n\\n\\tpublic Date getDate() {\\n\\t\\treturn date;\\n\\t}\\n\\n\\tpublic void setDate(Date date) {\\n\\t\\tthis.date = date;\\n\\t}\\n\\n\\tpublic String getRecipient() {\\n\\t\\treturn recipient;\\n\\t}\\n\\n\\tpublic void setRecipient(String recipient) {\\n\\t\\tthis.recipient = recipient;\\n\\t}\\n\\n\\tpublic int getStatusId() {\\n\\t\\treturn statusId;\\n\\t}\\n\\n\\tpublic void setStatusId(int statusId) {\\n\\t\\tthis.statusId = statusId;\\n\\t}\\n\\n\\tpublic String getStatusDescription() {\\n\\t\\treturn statusDescription;\\n\\t}\\n\\n\\tpublic void setStatusDescription(String statusDescription) {\\n\\t\\tthis.statusDescription = statusDescription;\\n\\t}\\n\\n\\tpublic String getClientRef() {\\n\\t\\treturn clientRef;\\n\\t}\\n\\n\\tpublic void setClientRef(String clientRef) {\\n\\t\\tthis.clientRef = clientRef;\\n\\t}\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nCreate a new servlet called ReceiptServlet.java\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"package com.dynmark;\\n\\nimport java.io.IOException;\\nimport java.lang.Integer;\\nimport java.text.ParseException;\\nimport java.text.SimpleDateFormat;\\nimport java.util.ArrayList;\\n\\nimport javax.servlet.ServletException;\\nimport javax.servlet.annotation.WebServlet;\\nimport javax.servlet.http.HttpServlet;\\nimport javax.servlet.http.HttpServletRequest;\\nimport javax.servlet.http.HttpServletResponse;\\n\\n:::at:::WebServlet(urlPatterns = { \\\"/receipt\\\" })\\npublic class ReceiptServlet extends HttpServlet {\\n\\tprivate static final long serialVersionUID = 1L;\\n\\tpublic static ArrayList<Receipt> receiptStore = new ArrayList<>();\\n\\n\\tprotected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {\\n\\t\\t// Do some basic parameter validation before processing\\n\\t\\tif (request.getParameter(\\\"datetime\\\") != null)\\n\\t\\t{\\n\\t\\t\\tSimpleDateFormat dateFormat = new SimpleDateFormat(\\\"yyyy-MM-dd'T'HH:mm:ss.SSS\\\");\\n\\n\\t\\t\\tReceipt receipt = new Receipt();\\n\\t\\t\\ttry {\\n\\t\\t\\t\\treceipt.setDate(dateFormat.parse(request.getParameter(\\\"datetime\\\")));\\n\\t\\t\\t\\treceipt.setRecipient(request.getParameter(\\\"recipient\\\"));\\n\\t\\t\\t\\treceipt.setStatusId(Integer.parseInt(request.getParameter(\\\"statusid\\\")));\\n\\t\\t\\t\\treceipt.setStatusDescription(request.getParameter(\\\"statusdescription\\\"));\\n\\t\\t\\t\\treceipt.setClientRef(request.getParameter(\\\"clientref\\\"));\\n\\n\\t\\t\\t\\treceiptStore.add(receipt);\\n\\t\\t\\t} catch (ParseException e) {\\n\\t\\t\\t\\tresponse.setStatus(HttpServletResponse.SC_BAD_REQUEST);\\n\\t\\t\\t}\\n\\t\\t}\\n\\n\\t\\tresponse.setStatus(HttpServletResponse.SC_OK);\\n\\t}\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nWe parse each piece of receipt data that arrives on out handler and push it into an ArrayList. In the real world we'd push receipts into a database or NoSQL storage via a decoupling buffer such as RabbitMQ and we'd also make sure we're threadsafe - we forward receipts on multiple threads!\n\nNow lets build some web UI to view the receipts. Create ReceiptViewer.jsp in /WebContent, which will read from our receipt \"storage\":\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"<%@page import=\\\"java.util.ArrayList\\\"%>\\n<%@taglib uri=\\\"http://java.sun.com/jsp/jstl/core\\\" prefix=\\\"c\\\"%>\\n\\n<html>\\n<head>\\n<title>Receipt Viewer</title>\\n</head>\\n <%\\n \\tpageContext.setAttribute(\\\"receipts\\\", com.dynmark.ReceiptServlet.receiptStore);\\n %>\\n\\n<body>\\n<table>\\n    <tr>\\n        <th>ClientRef</th>\\n        <th>Received At</th>\\n        <th>Recipient</th>\\n        <th>StatusId</th>\\n        <th>Status Description</th>\\n    </tr>\\n\\n    <c:forEach var=\\\"receipt\\\" items=\\\"${pageScope.receipts}\\\">\\n        <tr>\\n            <td><c:out value=\\\"${receipt.clientRef}\\\"/></td>\\n            <td><c:out value=\\\"${receipt.date}\\\"/></td>\\n            <td><c:out value=\\\"${receipt.recipient}\\\"/></td>\\n            <td><c:out value=\\\"${receipt.statusId}\\\"/></td>\\n            <td><c:out value=\\\"${receipt.statusDescription}\\\"/></td>\\n        </tr>\\n    </c:forEach>\\n</table>\\n</body>\\n</html>\\n\",\n      \"language\": \"html\",\n      \"name\": \"jsp\"\n    }\n  ]\n}\n[/block]","excerpt":"Sending text messages via the REST API","slug":"qs-java-receive-sms-receipts","type":"basic","title":"Receive SMS Receipts"}
