I'm a novice Grails Programmer.I have 2 use case :
render image file show on GSP Page.
render PDF file and show on PDF Viewer integrate with GSP Page.
Can anyone provide examples of how to do this?
Please provide some more details for your actions but roughly I suspect you might want the following:
<img src="${createLinkTo(dir: 'images', file: '1.jpg')}" alt="Image"/>
I don't know of any PDF viewers that could be integrated with an HTML page let alone a one that would be specific to grails. Your best bet is to redirect people to the PDF file and let their own browser handle the file.

My requirement is just to show the DVT hierarchyView in a HTML format in PDF, I don't want to embed the flash content in to PDF.
Also, the above links seems suggesting use of FLEX which we are not comfortable of.
Do you have any other pointers please
I am usieng PDFBox to fill a template with some data and I wish to render it in Chrome, so that I can give the user the possibility to preview it before printing it from the web page.
Does anyone knows if PDFBox supports to render the created PDF in a browser?
Thanks.
PDFbox not directly, since it just creates the pdf. But you can simply include the pdf in your webpage through varying methods, depending on your architecture.
One simple example is:
<embed src="http://example.com/file.pdf" width="500" height="500" type='application/pdf'>
More options have been discussed in this question: Recommended way to embed PDF in HTML?
I am developing a Java Web Application (jsp/servlet) using tomcat. I need to display pdf file from local machine. can you suggest what is best way to display it?
I used iframe to display pdf file.
<iframe src="resume.pdf" width="100%" style="height:60em">
[Your browser does <em>not</em> support <code>iframe</code>,
or has been configured not to display inline frames.
You can access the document
via a link though.]
</iframe>
I think you can try a Library called XPDF , I think you can convert from PDF to HTML page , or the second option is just let the user open a link to the page (www.yourwebsite.com/pdffolder/somepdf.pdf)
If you need display a pdf file using tomcat, you can access directly to the file using the specific url where the file is located in your navigator, depending on the path where you put the file, so you can access using 127.0.0.1/files/test.pdf for example. If you need generate a pdf, the best tool I think is iText, this is an easy example how to use id: Introducing PDF and iText
I developed a report (without and independent of any db datasource) only with iText. I know that with JasperReports this is easy. But in my case I just storage the report in pdf file or I used acrobat for java beans to show the report to user. Now I need to change my implementation code to show this report in web browser instead to save in the file.
How I can do this?
You need 2 thinks, first the browser plugin installed on the browser and second to set the content disposition header as inline in the respose, otherwise the browser will try to download it.
response.setHeader("Content-Disposition","inline; filename=\"file.pdf\"");
I assume that you've already set the Content Type to application/pdf and know how to convert an iText document to a bytearray and transmit it to the user.
A word of caution: if people outside your organization will use this app, the might not have the pdf plugin installed, in which case, the browse will download the pdf instead of displaying the pdf.
if the browser has the appropriate add-on installed, you can just drag and drop a pdf-file into the browser and it will show it.
Or if you have a site on which you want to present the pdf, you just put a link to it:
link to your pdf
Or did you mean you want to generate html-output for your report instead of pdf?
We have Flex on the front end and Java on the back end. When a user will request for a PDF file, request will go to the Java backend, where a PDF file will be generated using Jasper Reports. What we dont know is how to display this PDF file in browser; since we dont want to use JSP/Servlets etc - It has to be flex only. Any suggestions?
Flash Player cannot natively render PDF files. This is possible using Adobe AIR but not in a Flex application. Your best bet is to call navigateToURL() and open a Servlet in a new browser tab/window. The Servlet can simply write contents of the PDF file to the OutputStream and set the appropriate HTTP headers.
i think this question is old, but it may help others, there's a new library developed by Jasper Forge them selves, which deals with JasperReports directly, i mean it's not a PDF viewer, but a JasperReport exporting tool, you can download it from here
i tried it through using JasperServer, when viewing reports you can choose from different options to export it, one of them is flash, and it's working nice
Well for starters, PDFs don't always display in the browser. It depends on the user's settings. You essentially header them the pdf file and either they download it or a program like Acrobat Reader opens in the browser to display it.
Not sure how this is done in flex, I would imagine if you're using Java one simple servlet could do it.
