I can't create an external link (href) that open itself without the localhost:8080 in front of it

I'm trying to create a link (href) that open itself in a new page. Should be "simple".
That's the focus code:
if (propertybox.getValue(CandidatoLink.LINK) != null) {
Anchor anchor = new Anchor(propertybox.getValue(CandidatoLink.LINK),
propertybox.getValue(CandidatoLink.LINK));
anchor.setTarget("_blank");
return anchor;
}
This is to get the link from the database, like "www.google.com":
propertybox.getValue(CandidatoLink.LINK));
This is to get the link opening in a new tab of the browser:
anchor.setTarget("_blank");
It works all just fine: I can get the link opened in a new tab. The only problem is that the system think that's an intern page of the website and sees it as a Route! That's the problem. It will open a new tab with this link: http://localhost:8080/www.google.com
I can't remove the first part (http://localhost:8080/). Can someone help me?
I use Java 11.0.15, Vaadin 14 (Maven/Spring Boot) and my IDE is Eclipse 2022-06 (4.24.0).

How to get active Google profile name when I get the active Url from google chrome browser using C#

iam using this code to get the currently active tab open URL from Google Chrome browser.
public static string GetActiveTabUrl()
{
Process[] procsChrome = Process.GetProcessesByName("chrome");
if (procsChrome.Length <= 0)
return null;
foreach (Process proc in procsChrome)
{
// the chrome process must have a window
if (proc.MainWindowHandle == IntPtr.Zero)
continue;
// to find the tabs we first need to locate something reliable - the 'New Tab' button
AutomationElement root = AutomationElement.FromHandle(proc.MainWindowHandle);
var SearchBar = root.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));
if (SearchBar != null)
return (string)SearchBar.GetCurrentPropertyValue(ValuePatternIdentifiers.ValueProperty);
}
return null;
}
is there any way that I can return the current Profile name too? the profile name which I mean is found on the upper right part of the google chrome browser so it maybe has more than a profile with different names I want only to get the current name with the URL it comes from this function. I can open or use many profiles at the same time in google chrome, so I want to get the active Tab URL and the profile name with it or the email of that profile.
this an image of the profile name i want it from chrome to be sent with the currently active tab URL.
so i expect something like that for example to be done in c# to get the profile name
var SearchBar = root.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "profile email"));
last thing it can be c# or java codes if it can be better do in it also any solution that can get it in any programming language, please help with any information.
Thanks in advance.

You are going to have to dive into the HTML a little bit. Use chrome's developer features and inspect the HTML. You will find what class the username is under and the text is stored as the title find an example below.
<a class="gb_b gb_ib gb_R" href="https://accounts.google.com/" role="button" tabindex="0" title="Google Account: FillerFirstName FillerLastName (fillerEmail#gmail.com)" aria-expanded="false"><span class="gb_db gbii"></span></a>
You can accomplish this in many different ways with C#. I would recommend Selenium.

Cannot go to "chrome://downloads/" in a newly opened tab with Selenium in Chrome

I am using Selenium and Java to write a test for Chrome browser. My problem is that somewhere in my test, I download something and it covers a web element. I need to close that download bar (I cannot scroll to the element). I searched a lot and narrowed down to this way to open the download page in a new tab:
((JavascriptExecutor) driver).executeScript("window.open('chrome://downloads/');");
It opens that new tab, but does not go to download page.
I also added this one:
driver.switchTo().window(tabs2.get(1));
driver.get("chrome://downloads/");
but it didn't work either.
I tried:
driver.findElement(By.cssSelector("Body")).sendKeys(Keys.CONTROL + "t");
and
action.sendKeys(Keys.CONTROL+ "j").build().perform();
action.keyUp(Keys.CONTROL).build().perform();
Thread.sleep(500);
but neither one even opened the tab.

It is because you can't open local resources programmatically.
Chrome raises an error:
Not allowed to load local resource: chrome://downloads/
Working solution is to run Chrome with following flags:
--disable-web-security --user-data-dir="C:\chrome_insecure"
But this trick doesn't work with Selenium Chrome Driver(I don't know actually why, a tried to remove all args that appears in chrome://version, but this doesn't helps).
So for me above solution is the only one that works:
C# example:
driver.Navigate().GoToUrl("chrome://downloads/")
There is another trick if you need to open downloaded file:
JavaScript example:
document.getElementsByTagName("downloads-manager")[0].shadowRoot.children["downloads-list"]._physicalItems[0].content.querySelectorAll("#file-link")[0].click()
Chrome uses Polymer and Shadow DOM so there is no easy way to query #file-link item.
Also you need to execute .click() method with JavaScript programatically because there is a custom event handler on it, which opens actual downloaded file instead of href attribute which point to url where you downloaded file from.

I started with this post and ended up with the solution given below. This one works in Chrome 71. First I highlighted the control and then clicked it.
The window object is actually the IWebDriver, the second method is called after the first one.
internal void NavigateToDownloads()
{
window.Navigate().GoToUrl("chrome://downloads/");
}
internal void OpenFirstDownloadLinkJS()
{
IJavaScriptExecutor js = (IJavaScriptExecutor) window;
js.ExecuteScript("document.getElementsByTagName('downloads-manager')[0].shadowRoot.children[4].children[0].children[1].shadowRoot.querySelectorAll('#content')[0].querySelector('#details > #title-area > #file-link').setAttribute('style', 'background: yellow;border: 2px solid red;');");
js.ExecuteScript("document.getElementsByTagName('downloads-manager')[0].shadowRoot.children[4].children[0].children[1].shadowRoot.querySelectorAll('#content')[0].querySelector('#details > #title-area > #file-link').click();");
}

Use this code (I wrote it in Python, but it should work in Java too with very slight modifications):
#switching to new window
driver.execute_script("window.open('');")
driver.switch_to.window(driver.window_handles[1])
#opening downloads
driver.get('chrome://downloads/')
#closing downloads:
driver.close()

Getting started with developing for Chrome

I have been asked by my friend to make an application for Chrome and it requires me to have context-sensitive menus as below:
I have never really made anything for Chrome before and I have a few questions regarding it:
I will have to develop a plug-in, right ?
If so, is there a specific set of rules I have to follow ?
I know I can use GWT to compile Java to JavaScript
3. This context sensitive menu is the same as JPopupMenu ?
The application I want to develop is simple:
Copy some text,
right-click, click on the context sensitive menu
apply simple Caesar's cipher to the text
open a new JFrame with JtextArea in it to display the encrypted text.

What you're creating is called an "extension", not a "plug-in". A browser extension is written using HTML, CSS and Javascript, and got access to APIs for direct interaction with the browser.
Plug-ins, on the other hand, are compiled binaries such as Flash and Java.
Drop the idea of using GWT for Chrome extensions. It makes development of the extension harder, not easier (open issue).
Especially because you'll find plenty of vanilla JavaScript examples and tutorials in the documentation and Stack Overflow.
You just have to know the relevant APIs:
Copy some text,
right-click, click on the context sensitive menu
Use chrome.contextMenus. There's no need to copy, the selected text is available in the callback (examples).
apply simple Caesar's cipher to the text
Create a JavaScript function to achieve this.
open a new JFrame with JtextArea in it to display the encrypted text.
Create a new window using chrome.windows.create. You could include an extra HTML page in your extension, and use the message passing APIs to populate the text field, but since you appear to be a complete newbie, I show a simple copy-paste method to create and populate this window:
function displayText(title, text) {
var escapeHTML = function(s) { return (s+'').replace(/</g, '<'); };
var style = '*{width:100%;height:100%;box-sizing:border-box}';
style += 'html,body{margin:0;padding:0;}';
style += 'textarea{display:block;}';
var html = '<!DOCTYPE html>';
html += '<html><head><title>';
html += escapeHTML(title);
html += '</title>';
html += '<style>' + style + '</style>';
html += '</head><body><textarea>';
html += escapeHTML(text);
html += '</body></html>'
var url = 'data:text/html,' + encodeURIComponent(html);
chrome.windows.create({
url: url,
focused: true
});
}

Java SE: Open Web Page and Click a Button

I have a Java 7 program (using WebStart technology, for Windows 7/8 computers only).
I need to add a function so that my program clicks a button on a page with known URL (https).
Some people suggest WebKit SWT, but I went to their site and they say that the project was discontinued. (http://www.genuitec.com/about/labs.html)
Other people say that JxBrowser is the only option but it looks like it's over $1,300 which is crazy. (http://www.teamdev.com/jxbrowser/onlinedemo/)
I'm looking for something simple, free, lightweight, and able to open HTTPS link, parse HTML, access a button through DOM and click it. Perhaps some JavaScript too, in case there are JS handlers.
Thanks for your help.

You may be looking for HtmlUnit -- a "GUI-Less browser for Java programs".
Here's a sample code that opens google.com, searches for "htmlunit" using the form and prints the number of results.
import com.gargoylesoftware.htmlunit.*;
import com.gargoylesoftware.htmlunit.html.*;
public class HtmlUnitFormExample {
public static void main(String[] args) throws Exception {
WebClient webClient = new WebClient();
HtmlPage page = webClient.getPage("http://www.google.com");
HtmlInput searchBox = page.getElementByName("q");
searchBox.setValueAttribute("htmlunit");
HtmlSubmitInput googleSearchSubmitButton =
page.getElementByName("btnG"); // sometimes it's "btnK"
page=googleSearchSubmitButton.click();
HtmlDivision resultStatsDiv =
page.getFirstByXPath("//div[#id='resultStats']");
System.out.println(resultStatsDiv.asText()); // About 309,000 results
webClient.closeAllWindows();
}
}
Other options are:
Selenium: Will open a browser like Firefox and operate it.
Watij: Also will open a browser, but in its own window.
Jsoup: Good parser. No JavaScript, though.

Your question is kind of difficult to understand what you want. If you have a webstart app and want to open a link in the browser, you can use the java.awt.Desktop.getDesktop().browse(URI) method.
public void openLinkInBrowser(ActionEvent event){
try {
URI uri = new URI(WEB_ADDRESS);
java.awt.Desktop.getDesktop().browse(uri);
} catch (URISyntaxException | IOException e) {
//System.out.println("THROW::: make sure we handle browser error");
e.printStackTrace();
}
}
