Below I will show how to display PDF file download dialog to the user using REST JAX-RS.
My implementation below will NOT create PDF file in user's directory until the user choose "save as" in the dialog box.
To achieve this, I used ByteArrayInputStream class.
ByteArrayOutputStream baos = new ByteArrayOutputStream();
//This is just PDF generation API
JasperExportManager.exportReportToPdfStream(jasperPrint, baos);
byte[] entity = baos.toByteArray();
return Response.ok(entity)
.header("Content-Disposition", "attachment; filename=MyAwesomeJasperReportDownload.pdf")
.type("application/pdf")
.build();
Open2Test is add-on style keyword-driven framework which aims to replace test script with excel defined set of keywords.
http://www.open2test.org/
Today, I will explain how to define the keyword. The reason I'm posting such information is because Open2Test documentation is the worst documentation I've ever read. I know it's open source but lacking responsibility to guide users to the point that they can actually "use" it.
NOTE: Open2Test does not provide the forum to discuss about the framework but instead they have support email which you don't get response at all. (I sent 2 emails regarding to keyword definition etc and it has been a week since)
Since I used QTP to do my research, I will show how the keyword should look like.
I assume you have basic knowledge of how QTP works.
Object Repository
What makes QTP powerful tool is that it has Object Repository where you can store test object and all the test uses the repository. In the test script, you use test object name in the repository to refer to actually object such as DOM Element or Windows Object. Open2Test uses the test object name in the Object Repository.
For instance, in the QTP Object Repository, there is test objects of a website.
Now Open2Test keyword should look like below in order to type into the textbox.
r
wait
2
r
context
browser;myBrowser
page;myPage::frame;view
r
perform
textbox;FirstName
set:hello world
The first row - wait for 2 second
The second row - move focus to frame inside of page inside of browser
The third row - type "hello world" into the textbox.
I had to read source code of Open2Test QTP web to find out this. The documentation does not tell me how I should define context keyword. Anyway, I confirmed that above works just fine. If anyone has an issue please let me know I may be able to help
It is fairly easy to create HTML5 form validation with non-ajax.
But I found out that form validation with ajax is bit tricky. If anyone knows better way please let me know.
The problem was when to call setCustomValidity(). I had to call it inside of onclick event handler which runs
just before form submission.
So, when you click on submit button, onclick is fired and initValidation() is called. The method checks whether input is equals to the string "tt". If so it will set custom error message (i.e. setCustomValidity() )
You have to make sure to kill the submit by event.preventDefault()
NOTE: I tried this without using onclick. I put form validation code inside of submit() but setCustomValidation() is called too late there thus error popup didn't show up. (if you click submit one more time, it will show the popup.)
CODE:
$(document).ready(function() {
$("#myForm").submit(function(event) {
event.preventDefault(); //cancel submit
//your ajax code here...
})
});
function initValidation() {
var mtxt = document.getElementById("myText");
mtxt.setCustomValidity(""); //reset
if($("#myText").val() == "tt") {
mtxt.setCustomValidity("this is my custom error message");
}
}
I've seen countless Strategy pattern described on the web and none of them really get me so far.
They use Dog, Cat, Coffee, even worse, JComponent.. sure I can "programming to interface not implementation."
Still not getting it without writing my own strategy pattern with my own words. (Doesn't matter what terms I use, the point is I get the concept!)
Here is my version of strategy design pattern:
public interface Console {
public void launchGame();
}
public class XBox360 implements Console {
public void launchGame() {
System.out.print("I see the ring of death!");
}
}
public class PlayStation3 implements Console {
public void launchGame() {
System.out.println("SONY is being hacked by a kid");
}
}
public class Wii implements Console {
public void launchGame() {
System.out.println("I think my Wii controller is in my neighbor's backyard");
}
}
public class Me {
private Console console = null;
public Me(Cosole console) {
this.console = console;
}
public setConsole(Console console) {
this.console = console;
}
public void turnOn() {
if(console != null) {
console.launchGame();
}
}
}
public class Test {
public static void main(String[] args) {
Me me = new Me(new XBox360());
me.turnOn(); //"I see the ring of death!"
me.setConsole(new PlayStation3());
me.turnOn(); //"SONY is being hacked by a kid"
me.setConsole(new Me(new Wii());
me.turnOn(); //I think my Wii controller is in my neighbor's backyard")
}
}
I know there are many HTML5 form validation on the web but I made my own test demo so let me share.
The important thing is I wanted to create my own custom validation rule and custom error message.
I have 2 input text fields. Left field value has to be smaller than right field value. (like to-from date if u will)
Then my javascript compare each value and triggers custom validation error.
Note that you must remember to put empty string in setCustomValidity() otherwise after error is thrown, second time input will still cause custom error message to be shown.
