8:00 – 4:00 SR
- Still no server access. Looks like Dave W. is the hangup. Also, the reason that Ronda can’t get her Centrify account is because she doesn’t have access either.
- Added an “EchoServlet” to the YUITestServlets for playing with Angular. In retrospect, maybe we should have called this the JS-JavaServlets. Ah, well. Lockin sucks.
- After considerable flailing, figured out how to handle deployments (to the local Tomcat Server) in Webstorm. The process is as follows:
- Under the Tools tab, select ‘Deployment’, then ‘Configuration’. This will bring up the dialog that appears below. Click the green ‘plus’ to add a configuration.
- Give the configuration and a name, then set up the project file and urls as shown. Once that’s done, you can configure the mappings. Note that if the deployment options in the Tools->Deployment tab are disabled, you’ve probably messed up a mapping, so be careful here:
- The tricky part that I found is that there has to be at leas a ‘\’ in the deployment path or this doesn’t work. So just follow the above template and things ‘should’ work.
- Ok, got everything working. The following is a complete example that echoes the request from the client back from the server
- First, the html
<!DOCTYPE html>
<html ng-app="queryAppServlet">
<head lang="en">
<meta charset="UTF-8">
<title>Test</title>
<style>
.queryDiv {
background-color: lightgrey;
width: 700px;
height: 200px;
padding: 5px;
margin: 5px;
overflow: auto;
}
.responseDiv {
background-color: lightgrey;
width: 700px;
height: 400px;
padding: 5px;
margin: 5px;
overflow: auto;
}
p.messages{
font-size: 12px;
font-style: italic;
}
.results{
font-family: "Courier New";
font-size: 12px;
}
</style>
</head>
<body body ng-controller="MainCtrl as mainCtrl">
<div>Raw queries of irev database. Copy results and paste into Excel or .csv file</div>
<textarea class="queryDiv"contenteditable="true" ng-model="mainCtrl.query"></textarea>
<div></div>
<input type="button" value="Submit Query" ng-click = "mainCtrl.submit()"/>
<div class="responseDiv">
<p class = "messages">{{mainCtrl.message}}</p>
<div class = "results" ng-repeat="item in mainCtrl.items"> {{item}}</div>
</div>
<script src="libs/angular.js"> </script>
<script src="queryAppServlet.js"></script>
</body>
</html>
- Next, the Angular component:
var qa = angular.module('queryAppServlet', []);
qa.controller('MainCtrl', ['$http', function ($http) {
"use strict";
var self = this;
self.items = ["Ready"];
self.message = "No Messages";
self.submit = function () {
self.message = "No Messages";
var upstring = encodeURI("query=" + self.query);
var upObj = {
url: 'EchoServlet/foo.json',
method: "POST",
data: upstring,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
};
function goodResponse(response){
var data = response.data;
if (data['database access']) {
self.message = data['database access'];
self.items = [];
return;
}
if (data.connect_error) {
self.message = data.connect_error;
self.items = [];
return;
}
self.items = [];
var item;
var keys = Object.keys(data[0]);
var key;
var i = 0, j = 0;
var str = "";
for (i = 0; i < keys.length; i++) {
str += keys[i] + ', ';
}
self.items.push(str);
for (i = 0; i < data.length; i++) {
item = data[i];
str = "";
for (j = 0; j < keys.length; j++) {
key = keys[j];
str += item[key] + ', ';
}
self.items.push(str);
}
}
function errorResponse(response){
alert('queryApp.js: Error while fetching data from io2.php: '+response);
}
$http(upObj).then(goodResponse, errorResponse);
};
}]);
- Last, the Java Servlet

buf += "]";
System.out.println(buf);
rsp.setContentType("application/json");

} catch (IOException e) {
logger.error(e.getMessage());
e.printStackTrace();
}
}
