Drawing piechart in HTML email using Apache Commons Email - java

I would want to send statistical information to my clients showing the number of transactions processed on every terminal or branch. I am using Apache Commons Email to send HTML emails.
I would like to send a pie-chart data like this one on the site.
My java code is basic extracted from.
It goes like:
public void testHtmlEmailPiechart()
throws UnsupportedEncodingException, EmailException, MalformedURLException {
HtmlEmail email = new HtmlEmail();
email.setHostName(emailServer);
email.setSmtpPort(587);
email.setSSLOnConnect(true);
email.setAuthentication(userName, password);
email.setCharset(emailEncoding);
email.addTo(receiver, "Mwesigye John Bosco");
email.setFrom(userName, "Enovate system emailing alert");
email.setSubject("Conkev aml Engine Statistics");
URL url = new URL("https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcROXe8tn1ljtctM53TkLJhLs6gEX56CvL0shvyq1V6wg7tXUDH8KRyVP30");
// URL url = new URL("http://www.apache.org/images/asf_logo_wide.gif");
String cid2 = email.embed(url, "logo.gif");
email.setHtmlMsg("<html>\n" +
" <head>\n" +
" <script type=\"text/javascript\" src=\"https://www.gstatic.com/charts/loader.js\"></script>\n" +
" <script type=\"text/javascript\">\n" +
" google.charts.load(\"current\", {packages:[\"corechart\"]});\n" +
" google.charts.setOnLoadCallback(drawChart);\n" +
" function drawChart() {\n" +
" var data = google.visualization.arrayToDataTable([\n" +
" ['Task', 'Hours per Day'],\n" +
" ['Work', 11],\n" +
" ['Eat', 2],\n" +
" ['Commute', 2],\n" +
" ['Watch TV', 2],\n" +
" ['Sleep', 7]\n" +
" ]);\n" +
"\n" +
" var options = {\n" +
" title: 'My Daily Activities',\n" +
" is3D: true,\n" +
" };\n" +
"\n" +
" var chart = new google.visualization.PieChart(document.getElementById('piechart_3d'));\n" +
" chart.draw(data, options);\n" +
" }\n" +
" </script>\n" +
" </head>\n" +
" <body>\n" +
" <div id=\"piechart_3d\" style=\"width: 900px; height: 500px;\">Piechart Data</div>\n" +
" </body>\n" +
"</html>");
email.setTextMsg("Your email client does not support HTML messages");
email.send();
}
My guess is that the JavaScript is not recognized because the code works like sending images,styling fonts and I have sent to my email address some sample mail. I would like your help or recommendation of any material I can read to achieve this as long as am using Java.The processes is automated running in the background so no user interface is involved.
Thanks.

Spring cloud contract: using URL as response body parameter

In spring cloud contract (groovy) file I have issues with extracting a segment of request URL to use it as a parameter of in response body, e.g.
package contracts
import org.springframework.cloud.contract.spec.Contract
Contract.make {
description "Should return OK "
request {
url "/discovery.svc/something(\'${value(consumer(regex(".*")),producer('defaultSomething'))}\')"
method GET()
}
response {
status 200
body :
value(
consumer(file("response/defaultSomething.xml").file.write(
String.format("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<entry xmlns:metadata=\"http://docs.oasis-open.org/odata/ns/metadata\" xmlns:data=\"http://docs.oasis-open.org/odata/ns/data\" xmlns=\"http://www.w3.org/2005/Atom\" metadata:context=\"http://localhost:8082/discovery.svc/\$metadata#Environment/ContentServiceCapability\" xml:base=\"http://localhost:8082/discovery.svc\">\n" +

"</entry>", fromRequest().url().split('/')[-1].split('\'')[-2]))),
producer(file("response/defaultSomething.xml")))
)
}
}
the problen is that fromRequest().url() doesn't seem to be working and when I try to insert
print fromRequest().url()
in response section (in order to debug) I get as a result:
DslProperty{
clientValue={{{request.url}}},
serverValue={{{request.url}}}}
instead of plain string URL. .toString() doesn't help neither. Do you have any ideas how can I get request.url as a plain string?

Using javamail how do I send integer value 0

I have a utility which creates daily reports as Excel sheets containing the file processed details the failed ones and then sends out a mail to users and this code is written in Java.
When the value of the failed files is 0 the mail has a blank sent instead of 0.
This is the sample code
//sample piece of code
String bodyText = "<html>"
+ "<body style =\"font-family: Calibri; font-size:11pt; background-color:white \">"
+ "<table style =\"border:1px solid black;background-color:#DBE5F1;width:100%\">"
+ "<tr style = \"background-color:#DBE5F1 ;text-align-left; font-size:11pt\">"
+ "<br>"
+ "&nbsp Hi All,"
+ "</br>"
+ "<br>"
+ statusLine
+ "</br>"
+ " "
+"<br>"
+ "</tr>"
+ "<td style = \"text-align:right;width:10%;border-right:1px solid black\">"
+ caseCreated
+ "</td>"
+ "<td style = \"width:10%;border-right:1px solid black;text-align:right\">"
+ Failure
+ "</td>"
+"</html>";
//and for composing the mail message
message.setContent(bodyText, "text/html");

How to set the multiple attributes of objectClass for UnboundID & OpenLDAP via Java 7

I'm not sure how to properly pass the multiple attributes needed for an OpenLDAP insert via UnboundID. I have omitted the objectClass attributes & received a "no objectClass" error. I have also tried comma-separated & the bracket/array route like below & received the "value #0 invalid per syntax" error.
String[] ldifLines = {"dn: ou=users,dc=sub,dc=domain,dc=com", "cn: " + uid, "userPassword: " + pw, "description: user", "uidNumber: " + lclDT, "gidNumber: 504", "uid: " + uid, "homeDirectory: " + File.separator + "home" + File.separator + this.getStrippedUser(), "objectClass: {posixAccount, top}"};
LDAPResult ldapResult = lclLC.add(new AddRequest(ldifLines));
So, the question is, how do I successfully pass these objectClass attributes in the string array included above? Again, I have tried: "objectClass: top, posixAccount" as well. Thanks in advance!
It uses an LDIF representation, so if an attribute has multiple values, then the attribute appears multiple times. Like:
String[] ldifLines =
{
"dn: ou=users,dc=sub,dc=domain,dc=com",
"objectClass: top",
"objectClass: posixAccount"
"cn: " + uid,
"userPassword: " + pw,
"description: user",
"uidNumber: " + lclDT,
"gidNumber: 504",
"uid: " + uid,
"homeDirectory: " + File.separator + "home" +
File.separator + this.getStrippedUser(),
};
LDAPResult ldapResult = lclLC.add(new AddRequest(ldifLines));
Also, the LDAP SDK allows you to use a shortcut and just do it in a single call without the need to create the array or the AddRequest object, like:
LDAPResult ldapResult = lclLC.add(
"dn: ou=users,dc=sub,dc=domain,dc=com",
"objectClass: top",
"objectClass: posixAccount"
"cn: " + uid,
"userPassword: " + pw,
"description: user",
"uidNumber: " + lclDT,
"gidNumber: 504",
"uid: " + uid,
"homeDirectory: " + File.separator + "home" +
File.separator + this.getStrippedUser());

Loading local CSS file in WebView.replaceContent

I'm trying to implement a code editor in JavaFx using
https://gist.github.com/jewelsea/1463485
but the issue is that it downloads the CSS/Javascript from the internet to load CodeMirror. Is there a way to download those files and put them so that it can load them locally on Netbeans? I'm experienced with Java but not so much JavaFX or HTML.
I
Please put the CSS/Javascript in the classpath and use the following code:
private final String editingTemplate =
"<!doctype html>" +
"<html>" +
"<head>" +
" <link rel=\"stylesheet\" href=\"codemirror.css\">" +
" <script src=\"codemirror.js\"></script>" +
" <script src=\"clike.js\"></script>" +
"</head>" +
"<body>" +
"<form><textarea id=\"code\" name=\"code\">\n" +
"${code}" +
"</textarea></form>" +
"<script>" +
" var editor = CodeMirror.fromTextArea(document.getElementById(\"code\"), {" +
" lineNumbers: true," +
" matchBrackets: true," +
" mode: \"text/x-java\"" +
" });" +
"</script>" +
"</body>" +
"</html>";
I am just trying to pick the CSS/Javascript from the classpath instead of the internet

Java vs. Net HTTP Client Performance

We call a webservice from our C# app which takes about 300ms using WCF (BasicHttpBinding). We noticed that the same SOAP call does only take about 30ms when sending it from SOAP UI.
Now we also implemented a test accessing the webservice via a basic WebClient in order to make sure that the DeSer-part of the WCf is not the reason for this additional delay. When using the WebClient class the call takes about 300ms as well.
Any ideas on why Java compared to C# is about 10x faster in this regard? Is there some kind of tweaking possible on the .NET side of things?
private void Button_Click(object sender, RoutedEventArgs e)
{
executeTest(() =>
{
var resultObj = client.getNextSeqNr(new WcfClient()
{
domain = "?",
hostname = "?",
ipaddress = "?",
loginVersion = "?",
processId = "?",
program = "?",
userId = "?",
userIdPw = "?",
userName = "?"
}, "?", "?");
});
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
WebClient webClient = new WebClient();
executeTest(()=>
{
webClient.Proxy = null;
webClient.CachePolicy = new System.Net.Cache.RequestCachePolicy(System.Net.Cache.RequestCacheLevel.NoCacheNoStore);
webClient.Headers.Add("Content-Type", "application/xml");
webClient.Encoding = Encoding.UTF8;
var data = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ser=\"SomeNamespace\">" +
" <soapenv:Header/>" +
" <soapenv:Body>" +
" <ser:getNextSeqNr>" +
" <!--Optional:-->" +
" <clientInfo>" +
" <!--Optional:-->" +
" <domain>?</domain>" +
" <!--Optional:-->" +
" <hostname>?</hostname>" +
" <!--Optional:-->" +
" <ipaddress>?</ipaddress>" +
" <!--Optional:-->" +
" <loginVersion>?</loginVersion>" +
" <!--Optional:-->" +
" <processId>?</processId>" +
" <!--Optional:-->" +
" <program>?</program>" +
" <!--Optional:-->" +
" <userId>*</userId>" +
" <!--Optional:-->" +
" <userIdPw>?</userIdPw>" +
" <!--Optional:-->" +
" <userName>?</userName>" +
" </clientInfo>" +
" <!--Optional:-->" +
" <name>?</name>" +
" <!--Optional:-->" +
" <schema>?</schema>" +
" </ser:getNextSeqNr>" +
" </soapenv:Body>" +
"</soapenv:Envelope>";
string result = webClient.UploadString("http://server:8080/service", "POST", data);
});
}
Am I missing something here? Any idea would be helpful... ;-)
Kind regards,
Sebastian
I just found the reason for this.
It's the 100-Expect Continue HTTP Header and the corresponding implementation in .NET. The .NET client wait 350ms as default on the server. This causes the delays. Java seems to have other default values here...
Just add the following line of code very early in your code:
System.Net.ServicePointManager.Expect100Continue = false;
Cheers!
