Rookie Question about View

[bitapple]

Hi,

I need to manage a lot of pdf documents in my system.

Can i just do something like this?

<bean id="pdfViewResolver" class="org.springframework.web.servlet.view.Intern alResourceViewResolver">
<property name="prefix" value="/WEB-INF/templates/"/>
<property name="suffix" value=".pdf"/>
</bean>

so when my action controller received the request by document id like doc901, I just return "new ModelAndView("doc901")"
a pdf document at /WEB-INF/templates/doc901.pdf should be displayed to the user.

I have tried this, but it fails to display the pdf document.

Anyone can help me.

thanks,
victor

Why don't you simply put the .pdf in some directory on your webapp's root and let it be served by your appserver?

http://yourhost:8080/contextroot/pdf/doc901.pdf

No need to configure anything.

Do you want to open a link or do you want to stream the pdf to the client? It might be nessary to change the header. Have a look at the abstract pdf view.

To return a PDF to a browser I simply use the AbstractPdfView Class

There's a example in the countries example included in the distribution.

You should try to have a look

here's a very simple example :

my controller:
public class Send2Page implements Controller {



public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
return new ModelAndView(new HelloPdfView());
}

}


Here's the abstractPdfView

public class HelloPdfView extends AbstractPdfView {

protected void buildPdfDocument(Map model, Document document, PdfWriter writer,
HttpServletRequest request, HttpServletResponse response)
throws DocumentException, NoSuchMessageException {


document.add(new Paragraph("Hello World"));
document.add(new Paragraph("Salut, hello in french"));
Paragraph paragraph = new Paragraph();
paragraph.add("je suis vraiment hot");
paragraph.add("Sans Modestis ");
paragraph.add("une cellule ca fait quoi?");

document.add(paragraph);

}


}


And the config

web.xml

<servlet-mapping>
<servlet-name>springapp</servlet-name>
<url-pattern>*.pdf</url-pattern>
</servlet-mapping>


springapp-servlet.xml

<!--you will need you create a beanNameUrlHanlderMapping, if you are not
creating a SimpleUrlHandlerMapping-->

<bean id="defaultHandlerMapping" class="org.springframework.web.servlet.handler.Bea nNameUrlHandlerMapping"/>

<bean name="/showme.pdf" class="web.Send2Page">
</bean>


good luck man

Now I'm trying to open the pdf in a new window(new browser), so the user
don't have to click back in order to get back to application.
Do you where I can find the information?

hi,

i have static pdf documents created already (all are located under /WEB-INF/templates/pdf/). what i need to do is to collect pdf name from user, then return the specified pdf document to the user.

thanks

You understand your need now,

I don't know how to do it, but I guess will be to
render the pdf that user asked in a AbstractView and
then return it in a controller.

You should take a look at the class abstractPdfView and
AbstractView.

try to look a the source that comes with spring

try to look at how the people of Spring did extend AbstractPdfView
from AbstractView.

Also I remember that when I did that kinda stuff in the old fashion
way (servlet) I need to use
that line of command

response.setContentType("application/pdf");
read a pdf file,
and write it to the output stream (response.getOutputStream()

can't find example right now. sorry

But my advice before returning to the servlet mode,
try to a have a peek on the spring code. It comes with the
distribution, lot's a interesting stuff in.
