Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Hello Sirs
I am using serious issues with Charset Encoding in a REST application. I use Spring and the encoding in the bean MessageSource and Tymeleaf resolver  is set to UTF-8.
I get this when I return Json string:
\ufffd replacing special characters like é, or any other letter with accent.
How can I solve this?

Best regards.

is it good to have a ParseException or try catch   which would be much better way handling...

      @RequestMapping(value = "save/", method = RequestMethod.POST, produces = { "application/json" })
      public Map<String, Object> createCounseling(@RequestBody String counselingData) throws Parse{
            JsonObject CounselingObject = Json.parse(counselingData).asObject();
            HibernateDao<Counseling> workerDao = counselingDaoFactory.getNewDao(Counseling.class);
            Counseling counseling = getCounselingObject(CounselingObject);
            Map<String, Object> counseilingMap = new HashMap<>();
            counseilingMap.put("status", HttpStatus.OK);
            counseilingMap.put("data", new ArrayList<>());
            return counseilingMap;

Hey all I am using RFT in order to automate a page on a Pega website page. However, the automation doesn't seem to be able to fire off the change event of the input that I am inserting a string of text into. This input box seems to be located inside an iframe and perhaps this is the reason why its not firing the onchange event when losing focus on that input box?

RFT does use Selenium in their program to interact with the web page.

The html of the input box:


Open in new window

The Selenium code I have tried is this:


WebDriverWait wait = new WebDriverWait(driver, 10);
final WebElement BBOXInputBox = driver.findElement(By.id("BBOX"));


Actions builder = new Actions(driver);
builder.moveToElement(driver.findElement(By.id("FirstName_U")), 5, 5).click().build().perform();


Open in new window

And I am trying my best to find this function above in their 30 or so of .js files for any one page.

So someone more knowledgeable than I in the area of this type of coding in JS please set up and let me know what I should be looking for in the .js source code so that I can fire this change event manually within code.

It seems when I click on the text box, input a few letters and then either tab or click on another input box on that same form it fires some type of event/function that populates a label on the page.

What I have been looking for within the .js source code would be a function called refresh(...) or something along the lines of refresh: function(...)... or _refresh: function(...)... but I haven't been able to find anything that resembles the parameters its sending to that function.
