Creating dynamic html in java with itext best way to approach

Im using an example i found on stackoverflow to explain my problem.
Java code :
/**
* Example written by Bruno Lowagie in answer to the following question:
* RowSpan does not work in iTextSharp?
*/
public class ParseHtml {
public static final String DEST = "results/xmlworker/html_table_4.pdf";
public static final String HTML = "D:\\Users\\Documenten\\NetBeansProjects\\ItextTest\\recources\\xml\\table2_css.html";
public static void main(String[] args) throws IOException, DocumentException {
File file = new File(DEST);
file.getParentFile().mkdirs();
new ParseHtml().createPdf(DEST);
}
/**
* Creates a PDF with the words "Hello World"
* #param file
* #throws IOException
* #throws DocumentException
*/
public void createPdf(String file) throws IOException, DocumentException {
// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
// step 3
document.open();
// step 4
// XMLWorkerHelper.getInstance().parseXHtml(writer, document, null, null);
XMLWorkerHelper.getInstance().parseXHtml(writer, document,
new FileInputStream(HTML));
// step 5
document.close();
}

Can you create a dynamic table like this:
<table border="1" style="width: 100%">
<tr>
<td style="background-color: lightblue" height="15" >Srno</td>
<td style="background-color: lightblue">Particulars</td>
<td style="background-color: lightblue">Quantity</td>

<td valign="top">service.getsomevalue</td>
<td valign="top">service.getsomevalue</td>
<td valign="top">service.getsomevalue</td>
<td valign="top">service.getsomevalue</td>
<td valign="top">service.getsomevalue</td>
</tr>
}
As work around im using a stringbuilder. Where i create a temporarily html page then load the html page inside itext. But there has to be a better way ? Can someone give me some direction where to start ?

i am trying to do as like this http://www.shutterfly.com/ image upload.
any help will be appreciated, thank you friends...

You are navigating away using javascript, function CloseAndRefresh on clicking submit button.
What actually happens is that the uploading request is being submitted while the CloseAndRefresh function is being executed at almost the same time using different thread. If the upload request is not fast enough, the web page will get refresh first and your upload request get terminated immediately. There is no easy way to prevent this using your existing code.
You should use advanced method of uploading like jQuery uploading plugin to send the request. The plugin provide an binder to execute function on successful/failed submittsion.

Thank you gigadot, i solve the issue as like below,
The html form have the same code as i posted earlier, in the previous js code i have the CloseAndRefresh() method i remove it now from js as well as from the submit button onclick event.
When the form action called the controller, in which i have the code
#RequestMapping(value = "/upload", method = RequestMethod.POST)
public String UploadReceipts(#RequestParam("files[]") List<MultipartFile> file, Model model) throws IOException {
boolean status = false;
try
{
for(int i=0; i< file.size(); i++)
{
if(!file.get(i).isEmpty())
{
CommonsMultipartFile cm = (CommonsMultipartFile) file.get(i);
status = simpleUploadService.uploadFileandSave(cm);
model.addAttribute("status", status);
}
}
}
catch (IOException e) {
status = false;
model.addAttribute("status", status);
}
return "pages/simpleUploadStatus";
}
Now i redirect it to another page in which i throws the appropriate messages for the user.
that's all...

How to fetch from a jquery datatable an array of second colum cells subject to checkbox in first column

I have a table as follows
<table id="vainTbl6" class="dtable" cellpadding="3" cellspacing="1" border="0">
<thead>
<tr><th>check</td><th>Morphosal</th><th>goat </th><th>the other</th></tr>
</thead>
<tbody id="tbdy">
<tr class="gradeX">
<td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%">-Approve the femuneration Gommiqee purpirt</td>
<td>pontpose</td></tr>
<tr class="gradeX">
<td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%">-Declare a final truce</td>
<td>More</td></tr>
<tr class="gradeX"><td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%">-Amend the articles of asscotonation</td>
<td>Four</td></tr>
<tr class="gradeX"><td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%">-Re-elect Bandanna la banana for warden</td>
<td>Floor</td></tr>
</tbody>
</table>
and the first column is a checkbox. I need to fetch all the second column cells where the checkbox in the first column is set to true
I tried using this, but to no avail.
function extractRowCell(divNode){
alert(divNode.id);
$('#tbdy tr td').each(function() {
alert('hello');
var aRowData = this.cells
alert(aRowData[1].firstChild.value);
return aRowData;
});
}
The call is as follows:
<a id="la" href='#' onclick='extractRowCell(this.parentNode)' style="position:absolute; top:280px; left:350px;">Votes & Concerns</a>
The alert in the function triggers though with the correct value.
TIA

To iterate over the td's simply do the following.
$('#tbdy tr td').each(function() {
alert( $(this).text() );
});

You can do this
<table><tbody id="tbdy">
<tr class="gradeX">
<td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%" class="item">-Approve the femuneration Gommiqee purpirt</td>
<td>pontpose</td></tr>
<tr class="gradeX">
<td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%" class="item">-Declare a final truce</td>
<td>More</td></tr>
<tr class="gradeX"><td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%" class="item">-Amend the articles of asscotonation</td>
<td>Four</td></tr>
<tr class="gradeX"><td><input type="checkbox" class = "chcktbl" /></td>
<td style="width:55%" class="item">-Re-elect Bandanna la banana for warden</td>
<td>Floor</td></tr>
</tbody>
</table>
<button>Get</button>
<script>
$("button").click(function(){
var ret="";
$("#tbdy tr td:first").each(function()
{
if($("input:checked").length!=0)
{
ret=$("input:checked").parent().parent().find("td.item").text();
}
});
alert(ret);
});
</script>

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.
