Spring-Thymeleaf How to invoke with EL an action method from a Bean

I am using Spring/SpringMVC 5.x version, with Thymeleaf and Bootstrap on Tomcat server.
I need to ask something that maybe it might look to you very "st#pid" question.
In my html view I have the following button or a link:
<input type="button" .../>
<a .../>
I don't need to submit something, so I just use a simple button, so I think I don't need any form for it (except if I need for this).
In this html view (because of the thymeleaf library I added in the html tag), I need to add somehow,
(but I don't know how), to this button or in the link, an expression of Spring EL or Thymeleaf EL, so I can invoke a method from a
Spring bean, that I passed in the view, via a model which I added in my controller, e.g.:
${myBean.doSomething()
// or
${myBean.doSomething(parameters)
If this is not understandable I can update my question with some code (I believe that Spring developers
understand what I am talking about).
I don't know how to pass this expression. What attribute of button or link tag to use?
I used "action" attribute for the button:
<input type="button" th:action="${myBean.doSomething()".../>
or "href" attribute in the link tag:
<a th:href= "${myBean.getStringUrlAndDoSomething()"/>
Very significant info
When I started my tomcat running the page, the actions in the EL are run successfuly on the load of the page. When I pressed the button or the link nothing happened.
I know that I cannot use "onclick" attribute because there we write JS code.
But I need to run Java Spring code.
Any ideas about solving my problem?
Thanks in advance

I followed the advice of the #M.Deinum, #Wim Deblauwe, and I did not use
a button for this job. Button needs a form to work.
That is why I used a link, where the method from the bean is called like a charm, like
the following snippet:
<div class="blabla">
<div class="blablabla" th:text="|#{change_lang} EN/GR:|"></div>
<a class="bla" th:href="${localeService.switchLocale()}">
<div th:class="|${localeService.loadCss()}_blabla|"></div>
</a>
<span th:text="${#locale.getLanguage()}"></span>
</div>
And next is a snippet from the bean:
public String switchLocale() {
locale = LocaleContextHolder.getLocale();
if (locale.getLanguage().equals("en")) {
LocaleContextHolder.setLocale(EN_LOCALE);
return "?lang=el";
} else if (locale.getLanguage().equals("el")) {
LocaleContextHolder.setLocale(GR_LOCALE);
return "?lang=en";
} else {
return "";
}
}
So, the code from the bean IS invoked successfuly. I guess this is the solution to my issue.
Thanks a lot from the 2 people #M.Deinum, #Wim Deblauwe, who advised me.

Java Selenium how to select child elements if they exist from multiple same parent elements

I'm trying to get contact information off a webpage. Each contact is listed within an info class. The information I want is found in an n, adr, and primary phone class. What I want to do is iterate through each info element, check if it has those 3 child elements, and if all 3 exist add it to an ArrayList.
Heres an example of the basic parent-child relationship in the html
<div class = "info">
<h2 class = "n">Header</h2>
<div class = "info-section info-primary">
<p class = adr> address here </p>
<ul class = "phones> phone# </u>
</div>
</div>
Thanks to those that helped me I was about to get only the child elements that I want. However, I need to check and make sure each parent element contains those child elements then add them to my list.
For Example: one contact could be
<div class = "info">
<h2 class = "n">Company Name</h2>
</div>
</div>
Since there is no phone or address listed I don't want to get them from the webpage, and move to the next contact.

Since all information you need is present on html by tags and classes, you just need to write a selector that be able to filter it to you, and not only using a Java code to do that.
Without a full HTML, is hard to imagine or think the better way to write a selector for you (CssSelector or XPath still looks the better options here). So, you can try the following CssSelector, or adapt it for what you need:
driver.findElements(By.cssSelector(".info > h2 .info .adr, .info > h2 .phones"));

Filling out a HTML-form with complex name (dot-notation in input-tag) with Java and Jaunt API

-
hey folks,
i am building a Java-tool, trying to automatically fill out some form input elements in an HTML-Page using Java and Jaunt API.
the HTML-Code is like:
<fieldset class = "fieldsetlong">
<legend>searchprofile</legend>
<label for="reference">reference:</label>
<input maxlength="50" name="reference" id="reference" type="text" />
</fieldset>
<fieldset class = "fieldsetlong">
<legend>searchcriteria</legend>
<label for="surname">surname:</label>
<input name="searchprofile.surname" id="surname" type="text" />
</fieldset>
The Java-Code for filling in the "normal" Input-field reference (it works) looks like:
form.set("reference", "123Test");
Unfortunately, I am not able to fill out the fields that use the dot-notation searchprofile.surname in the name
Here's a sample of what i've tried (without success):
form.set("surname", "TestPerson");
form.set("searchprofile.surname", "TestPerson");
form.set("name=\"searchprofile.surname\"", pers.getSurname());
form.set("id=\"surname\"", pers.getSurname());
For each of these commands I get a NotFoundException and don't know whether I can do this with Jaunt.
It would appreciate any kind of help in this regard.
Thanks in advance
Edit - is there a way to reach the dot-notated input-field searchprofile.surname with JSoup?
HTML allows dots in the name-Attribute, but does Jaunt accept this abc.name?

Not sure about Jaunt, never used it before. However Jsoup seems to be a pretty decent library to be used here. I myself have been using Jsoup for a fairly long time and it has been very successful in scraping web pages, filling input form and submit, and of course, HTML parsing!
I've posted a step by step guide to fill in form input fields and submit to server in the following answer: How to login with Jsoup
Basically it works very similar to your code, a very brief example would be:
Connection.Response response = Jsoup.connect(url)
.data("Name", "Value")
.method(Method.POST).execute();

Today, at work the Jaunt solution with
form.set("searchprofile.surname", "TestPerson");
worked like a charm.
I don't know what the problem was earlier but I am glad that it worked.
The HTML allows to use dots and minus, etc. which I misinterpreted as some kind of nested forms or hierarchies but the dot-notation is just a valid name-attribute in HTML.

I need to fetch :
What I need to fetch from the site:
entry-title. -> document.getElementByClassName("entry-title");
entry-link -> document.select("span.entry-title > a[href]")
summary of the entry. -> document.getElementByClassName("entry-summary");
author's link. -> document.select("span.author > a[href]")
author's name. -> document.getElementByClassName("author");
category. -> document.getElementByClassName("cat-links");
category's link. -> document.select("span.cat-links > a[href]")
posting date -> document.getElementsByClass("published");
I am doing it by this way:
Document document = Jsoup.connect(url).get();
heading = document.getElementsByClass("entry-title");
headingLink = document.select("h1.entry-title > a[href]");
headingSummary = document.getElementsByClass("entry-summary");
author = document.getElementsByClass("author");
authorLinks = document.select("span.author > a[href]");
category = document.getElementsByClass("cat-links");
categoryLinks = document.select("span.cat-links > a[href]");
published = document.getElementsByClass("published");
It is working well but working very slowly. How should I change my code for the same. Please help me.

Some hints from luksch:
From my experience Jsoup is doing a pretty good job speed wise, altough a SAX based approach should be a bit faster. Anyway, I use Jsoup a lot and never found it slow. Network access however can be very slow, depending on a lot of parameters, some of which you don't have much control over. I advise you to check out the connection over which you retrieve the data. Maybe this is the culprit and not JSoup parsing.
your JSoup use seems okay to me. At least I don't see a way to speed that up by much. One thing could be to restrict the search for Elements by not starting at the document level, but at a suitable inner node. element.select(".whatever") will start at element not at the document. If your document is very big, this might help

Vaadin FormLayout formatting

Im new at vaadin 7 and have a little issue with formatting.
I have spend a few hours but no luck.
I have:
2 Form layouts on my vertical Layout.
2 Labels on each form layout.
Better check the screenshot
I want format label test as on the right part of screenshot.
Can you please advice or share thoughts or ideas.

I'm not 100% certain if I get what you're trying to do, but you might be able to achieve this through custom CSS.
It is hard to write out the exact CSS since it would require seeing the HTML generated by Vaadin and testing it with that, but it would be something like this for the labels:
.padded-form-layout v-caption:first-child {
float: left;
padding-left: 30px; /* set desired padding used for each label */
}
Of course, you'll need something similar for the values as well.
Above, padded-form-layout is the class name you define for layouts that need this look. In Java:
formLayout.setStyleName("padded-form-layout");
To figure out what the CSS modifications needed are I recommend you open the page in browser (Chrome or Firefox will do) and use the dev tools to directly modify the CSS to figure out what rules are needed. I usually do this by simply typing a style tag to the element, something like this (in this example, style="XXXXX" would be added manually. This is possible at least with Chrome's developer tools):
<div class="v-formlayout v-layout v-widget v-has-width" style="width: 100%;">
<!-- ... -->
<td class="v-formlayout-captioncell">
<div class="v-caption v-caption-hasdescription">
<span id="gwt-uid-21" for="gwt-uid-22" style="XXXXX">First name:</span>
<span class="v-required-field-indicator" aria-hidden="true">*</span>
</div>
</td>
<!-- ... -->
</div>
To be able to use the CSS, you'll need to either add it to your theme somehow and compile it (see Vaadin documentation about themes), or by using the #StyleSheet annotation
