FOP and strus
Hi, I am looking into FOP in generating PDF in
struts... the examples so far that I have seen are
only taking static XML files and XLS files. Can
someone tell me how to use FOP to generate pdf with
dynamic XML string (generated by some java objects) on
the fly?
I would apprecaite if you could even provide me with
some sample code.
Thanks
John

John,
We wrote a servlet that took the name of a URI as a parameter.
That URI, essentially mapped to a JSP, whose output was FOP.
The servlet:
requested the URI, got the FOP, formatted the FOP, then sent that back to
the browser. This may not be ideal for all situations, but it worked nicely
for us.
You could look at using something like webmacro/velocity as it would be
neater than a JSP for
this. It depends on what you are doing.
Regards,
Nick

Re: FOP and strus (IE problem)
Posted by Tadashi Ishikawa <is...@wink.tis.co.jp>.
I had the same problem.(Not IE problem)
FOPServlet works fine under Tomcat3.2.3 and OC4J(Orion).
IE has a URL problem. but this is not the case.
FO -> FOP -> PDF works fine under WebLogic6.1sp1 as well.
XML + XSL ->Xalan ->FO -> FOP ->PDF won't work.
PDF file size was 0 in NN also.
I thought Xalan failed. I noticed FO wasn't created. but I got no exception.
I changed server's CLASSPATH. but nothing was changed.
I think this problem is specific to weblogic. and I couldn't solve it.

RE: FOP and strus (IE problem)
Posted by Robert <rm...@bull-enterprises.com>.
I realize I'm jumping in this one late, so forgive me if I restate what
some others have, but:
a) no, you shouldn't have to do anything with your web/app server at
all.
b) This is a bug with IE, in that it tends to ignore content types if it
thinks it 'knows' what the content is (by what the URL ends with), so as
others have said, you should be able to set the content type and either
set the URL to end with a '.pdf' or NOT end with it (then IE checks the
content type) The Cocoon site mentions this as well, as they have a FOP
example in their distro that out of the box doesn't work in IE because
the URL actually end in .xml so IE thinks it's an XML document even
though cocoon sets the content type.
c) What _exactly_ is happening? Are you getting a browser full of funky
text, nothing at all, crashing, etc.?

Oh, what a world of pain.
IE in this regard is a pile of *@!# and NS is the absolute honey :)
This is off-struts, but I know the pain you go through to get IE going
properly.
Here's what I had to do to get it running reliably...
// START CODE --==>>
// set the response type
response.setContentType("application/pdf");
// set the content details
response.setHeader("Content-Disposition", "inline;
filename=ConfirmationLetter.pdf; ");
// creating a temporary output stream
ByteArrayOutputStream bout = new ByteArrayOutputStream();
// this class takes teh xml document and runs it through the FOP process
// and pumps it into the output stream created.
OnlineSalesPDFGenerator pdf = new OnlineSalesPDFGenerator(xmlDoc);
pdf.run(form,request,bout);
byte[] content = bout.toByteArray();
// set the exact content length from our temp output stream
response.setContentLength(content.length);
// write the content
response.getOutputStream().write(content);
// flush the stream
response.getOutputStream().flush();
// <<==-- END CODE
I went through a lot of pain to get all the alternatives people were
doing to get this. Important parts are...
a) The response type.
b) The Content-Disposition details. This sets filenames and stuff for
the file saving dialog boxes etc.
c) Setting the exact content length. Made possible by writing to the
ByteArrayOutputStream and getting its resulting size.
And if you're pessimistic (most likely you are by now :), make sure you
flush and close the output stream, and you can also throw in what Gregor
says below with your URL. After the above though, you shouldn't have any
problems.
Hopefully this will get you where you need to be.

One approach would be to convert java objects to xml using Castor and then
pass the XML to FOP.
