how to know which button is clicked in jsp foreach loop - java

I have a JSP page that's attached to a list of objects I need to loop through using a JSTL loop. Basically, I want it to display different information about the book and a submit input view (send to another jsp page to see more details about the book).
My question is how can I know which button was clicked and how can I recover the corresponding book.
<table class="table table-striped">
<thead>
<tr>
<th scope="col">N°</th>
<th scope="col">Title</th>
<th scope="col">ISBN</th>
<th scope="col">Author</th>
<th scope="col">Year</th>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row"></th>
<c:set var="count" value="${1}" scope="request"/>
<c:forEach items= "${requestScope.booksList}" var="b">
<tr>
<td>${count }</td>
<td> ${b.getTitle() } </td>
<td> ${b.getISBN() } </td>
<td> ${b.getAuthor() } </td>
<td> ${b.getYear() } </td>
<td><input type="submit" value="View" name="View${count }"></td>
<td><input type="submit" value="Mark" name="Mark"></td>
</tr>
<c:set var="count" value="${count + 1}" scope="request" />
</c:forEach>
</tr>
</tbody>
</table>

Setting HTML content to JTextPane messes up System.out redirection

I am using the MessageConsole class to redirect System.out and System.err to a JTextPane named jMessageConsoleTextPane.
I am configuring it in my constructor like this:
jMessageConsoleTextPane.putClientProperty(JEditorPane.HONOR_DISPLAY_PROPERTIES, Boolean.TRUE);
MessageConsole mc = new MessageConsole(jMessageConsoleTextPane, true);
mc.redirectOut(null, null);
mc.redirectErr(Color.RED, null);
mc.setMessageLines(100);
and also in NetBeans I have it set to contentType text/html.
It prints everything fine with System.out and System.err but here comes my problem. I try to set the text of jMessageConsoleTextPane to an html table (which contains two other html tables) that I have created based on some variables, so I do:
String htmlTable = WordCounting.getHtmlTable(wordsArrays, hashtagsArrays);
jMessageConsoleTextPane.setText(htmlTable);
Here is how the htmlTable String can look like (taken straight from the debugger):
<html>
<body>

Here is how it looks in the jMessageConsoleTextPane:
Then I try to use System.out which should print bellow text:
[23:19:32] Getting driver...
[23:19:32] Connecting to database...
[23:19:32] Executing query...
5.6.16
and this happens:
Basically everything is getting added on the last cell of the second table. Even if I do jMessageConsoleTextPane.setText("") there is a sole table cell remaining like this (top left):
So what is going on? Why is there a cell left and how do I fix it?

The MessageConsole class was not designed to be using with HTML. All the class does is add the text to the end of the Document, which in your case appears to be the last cell of the table.
You can try adding an empty HTML tag to the Document when you first create the HTML. Then maybe the text will be added to this tag instead of the table cell.
Maybe something like:
</table>
<p></p>
</body>
This all depends on how the Document parses the text that is inserted into the Document.

My target is to click on second Pearl text related input field
Selenium code is the following:
driver.findElement(By.xpath(".//td[contains(text(),'Pearl')][1]/preceding-sibling::td")).click();
Problem:
Above code always working with first table that contains Pearl text
Observations:
That case when im modify first Pearl text to something else the code working fine
That case when im working with another text ect:"ravenclawn" its working fine without any modifications
Thanks for any advice

You just include index for table also.
For 1st table
By.xpath("//table[1]//td[contains(text(),'Pearl')]/preceding-sibling::td")
For 2nd table
By.xpath("//table[2]//td[contains(text(),'Pearl')]/preceding-sibling::td")

Web Flow problems from GET Jsp to a POST JSP (Form) - Spring MVC Annotated

i have a JSP with hyperlink
<table>
<tr>

<td>${product.name}</td>

<tr>
<td>Description:</td>
<td>${product.description}</td>
</tr>
<tr>
<td>Price:</td>

<table>

<td>Logout

And the controller
#Controller
#SessionAttributes("basket")
public class ShopBasketController {
private BasketManager basketManager;
private CustomerManager customerManager;
private CategoryManager categoryManager;
#Autowired
public ShopBasketController(BasketManager basketManager, CustomerManager customerManager, CategoryManager categoryManager) {

this.customerManager = customerManager;
this.categoryManager = categoryManager;
}
#RequestMapping(value="/basketItems", method=RequestMethod.POST)
public String removeProduct(#ModelAttribute("basket") Basket basket, BindingResult bindingResult, Model model) {
Basket newBasket = ShoppingBasketUtils.removeFromBasket(basket, basketManager);
basketManager.update(newBasket);
model.addAttribute("basket",newBasket);
model.addAttribute("customer", "Sonx"+" Nkuks");
model.addAttribute("totalItems", basketManager.getTotalNumberOfItems(basket));
model.addAttribute("totalPrice", ShoppingBasketUtils.currencyFormat(basketManager.getTotalProductPrice(basket)));
return "basketItems";
}
#RequestMapping("/populateBasket")
public String populateBasket(#RequestParam("code") String productCode, #RequestParam("name") String categoryName, Model model) {
Customer customer = customerManager.getCustomer("Sonx", "Nkuks");
if(customer != null) {
Basket shopBasket = ShoppingBasketUtils.addToBasket(productCode, categoryManager.getCategory(categoryName),
basketManager.getBasket(customer.getReferenceNumber()), basketManager);
basketManager.update(shopBasket);
model.addAttribute("basket",shopBasket);
model.addAttribute("customer", customer.getFirstName()+" "+customer.getLastName());
model.addAttribute("totalItems", basketManager.getTotalNumberOfItems(shopBasket));
model.addAttribute("totalPrice", ShoppingBasketUtils.currencyFormat(basketManager.getTotalProductPrice(shopBasket)));
return "basketItems";
}
model.addAttribute("customer", "test".concat(" test"));
return "/error";
}
}
Then the form ...

When i press the link from the first JSP "" the controller succesfully execute the method populateBasket and loads the Form. But when i submit the form, i want it to call the POST method (basketItems)... But it doesn't, pressng the submit button always executes the GET method (populateBasket) .. This doesn't happen if i load the form directly from the index page, it loads successfully . Problem is when coming from that JSP ?

If you want the form to submit to a different URL from the one that was used to retrieve the page, you need to explicitly set the action on it. Otherwise Spring is going to just fill it in with the current URL.
