i am using GWT/EXTGWT. on click of submit button i get list of records from db. i need to export them to pdf. please suggest me how to do this?
if data to be exported is more then that should be exported to multiple pages.
Thanks!
There's little in context of GWT here, apart from the fact that you have a GWT based application. What you are really looking for is a tool that generates PDF, given data.
There are hosts of them available :
iText
jPDF Writer...
Obviously, iText has been the most widely known and successful one! Here's a good tutorial - http://www.vogella.de/articles/JavaPDF/article.html
Try some tools like itext pdf generator Searching online will give you many more options.

The obvious primary reason for using iText being , our company already have a license.
Requirement:
Generate a report that includes pie chart.
Our UX gave us a HTML, And I'm using html2pdf plugin to generate pdf.
We're using tlx-chart for its simplest code.
Issue:
PDF doesn't render/show piechart. No errors seen in logs.
HTML is being created perfectly (Althought iText conversion seems to be not so good), and When I load it with chromedriver as provided in KB article below, it renders overlapped 2 piecharts instead of 1.
So, This knowledgebase article from iText doesn't help.
Infact, I've thought I cannot keep on updating chromedriver,selenium on prod server.
I've to provide a loosely coupled (OS>PDF>PIE) to generate PDF.
Code Snippet:
HtmlConverter.convertToPdf(reportHtml, pdfWriter, new ConverterProperties());
"<tlx-chart id=\"mychart\" chart-type=\"PieChart\" chart-editable=\"true\" chart-columns=\"${['Element','Percentage']}\" chart-data=\"${${pieData}}\" </tlx-chart>"
Please Help!
So the issue is to embed piechart in PDF since JavaScript tags were not being rendered by iText library. And I resolved this in my case using jFreeChart.
Generate an image using jFreechart and embed that image in HTML
iText perfectly renders this as per HTML CSS

Can someone supply an example or a link to an example that signs an existing pdf using itextsharp 5.4.4? Ideally keeping pdf/a conformity of the pdf? Thank you.
Edit: I understand the question looks as if I did not use google etc. BUT, new versions of itextsharp contain completely rewritten code for signing as well as other functions, making the existing examples non-functional. Also, itextsharp started using different names for methods eg. instead of createSignature one has CreateSignature, instead of getSignatureAppearance one seems to have SignatureAppearance etc. making the port from java examples a real nightmare. Also the samples in the source code itself are in java not c#. There is really nowhere else I can go.
Please read http://itextpdf.com/book/digitalsignatures
The examples are in Java, but they were also ported to C#. You can find the C# examples here. I didn't vote your question down, but... the first place to go when you have a question about iText should probably be http://itextpdf.com
The book I refer to (I'm the author) as well as the new examples are on the learn page.
I need to update some cells in google doc spreadsheet on iPhone app.
I've downloaded GData source and example projects (not iphone specific) but I can't seem to get it to work. Does anybody know of any good (or any at all ;)) tutorials out there?
Best regards.
The file SpreadsheetTableSampleWindowController.m has examples of using tables and records in spreadsheets. The method randomizeSelectedTable shows how to fill cells with randomly-selected strings.
Have you looked at the introduction? Or maybe you could post the error message your getting or the problem your running into.
I am working on a small app, which can open a pdf. My question is, if it is possible to access a hyperlink from a pdf? Because when am trying to click on hyperlink nothing is happening and it's not redirecting me to the link. I tried searching a lot but didn't got any luck on this. Am expecting a quick response as my work is getting delayed because of this issue. If it's possible then what would be the approach? Right now am using UIWebView to open the pdf. Any sample app or code will be of great help.
Thanks for your time .
The only way I know is to use a third party library (or perhaps parse the PDF yourself), find the links, get their rects and catch user taps and compare that to the list of link/hyperlinks/gotos for that particular page.
Unfortunatelly - nothing in the SDK that can help. You can search for a opensource pdf library, like muPDF for instance.
There is a reason why not many applications have that functionality :D
Not that it is all that entirely practicle, I have a particular customer that is wanting to turn off the title pages in their PDFs that are getting generated. I looked and looked through the DocBook FOP parameters and documentation and couldn't find a way to disable the titlepage. I found ways to customize however.
Use a PDF filter and strip away the first page?
I ended up changing the document type from a book to an article. This removed the title page and everything else not needed.
I've just started looking into docbook and this is also what I'm trying to do at the moment. As far as I've read it is suggested to create a custom titlepage xsl (which could be genereted from your own titlepage.xml file - sample could be found under docbook-xsl-ns-1.76.1\template)
It's explained here : http://www.sagehill.net/docbookxsl/HTMLTitlePage.html
You simply have to add this to your stylesheet:
<xsl:template name="book.titlepage.recto"/>
<xsl:template name="book.titlepage.before.verso"/>
