What example were you referring to? You might want to try the
"weather" web service example in the Sandbox, which calls a web
service directly with an XForms submission, which is what we now
recommend. See:

Alex,

The examples on this site:
http://www.orbeon.com/ops/doc/integration-webservices
And also:
http://www.orbeon.com/ops/doc/processors-delegation#web-service

I tried it via the xforms submission method but I think I maybe be
having problems with Orbeon trusting the certificate that the webservice
serves. I use
https://admin:xxxx@172.20.178.130/iControl/iControlPortal.cgi as the
URL. The log file shows:

2008-07-16 08:04:09,060 http-8080-Processor19 ERROR

.

Is there a truststore that orbeon can use?

And regarding the issue with the delegation processor, this looks like
an integration issue with Liferay. I am not sure why the Liferay class
com.liferay.util.axis.SimpleHTTPSender can't be initialized in this
case. Hopefully you'll get around this by using an xforms:submission,
which we would recommend anyway independently of this issue with
Liferay.

Hello all,

I know there is a pdf template processor but I was keen to investigate
this path to create a pdf, so I tried a submission which would run the
xpl:

        <p:processor name="oxf:xslfo-converter">
                <p:input name="config">
                        <config/>
                </p:input>
                <p:input name="data">
                        <fo:root>
                                <fo:layout-master-set>
                                        <fo:simple-page-master
master-name="A4-portrait" page-height="29.7cm" page-width="21.0cm"
margin="2cm">
                                                <fo:region-body/>
                                        </fo:simple-page-master>
                                </fo:layout-master-set>
                                <fo:page-sequence
master-reference="A4-portrait">
                                        <fo:flow
flow-name="xsl-region-body">
                                                <fo:block>Hello,
Bob!</fo:block>
                                        </fo:flow>
                                </fo:page-sequence>
                        </fo:root>
                </p:input>
                <p:output name="data" ref="data"/>
        </p:processor>

In the page flow:

<page path-info="/demo/pdf" view="print-pdf.xpl"/>


I wasn't sure what to put for the view or model so I just added this and
I get a page with what seems to me is the binary representation. I am
not sure how to serve this back to the client though as a pdf.

Does anyone have an idea?

Thanks,
Naman

It's probably the mime-type - not sure, but maybe outputting via a page-flow
view is upsetting the mime-type somehow.

You could instead have your print-pdf.xpl as a model in the page flow.

Then pipe the output through a oxf:http-serializer - in the config input of
that processor you can specify the mime-type for a pdf as application/pdf.

You don't need to run the xslfo-converter yourself (and if you do, you
should do it in a model which takes care of the HTTP serialization,
not in the view). Instead, just let your view produce XSL-FO. The
epilogue will detect that, run the xslfo-converter and serialize the
output as appropriate.

Alex,

Sorry to be a pain, but I am a little confused when you say "let your
view produce xsl-fo". What I wanted to do was:
        1. Press a button 'mViewHome.xhtml' which would convert the xml
in that instance into pdf
        2. 'print-pdf.xpl' would use XSLT to produce XSL-FO code which
would create a PDF which would be served back to the client.

I have attached my understanding of the implementation. I also tried
using xsl-fo serialization but wasn't sure how to use it.

You might want to give a try to what follows:

1. Change your page-flow.xml to use view="print-pdf.xpl" instead of
model="print-pdf.xpl".
2. Change print-pdf.xpl to remove the oxf:xslfo-serializer and connect
the output of the stylesheet directly to the "data" output of the
pipeline.

The epilogue will be looking at what your view generate: if it
generates XHTML with XForms, it will do its XForms processing, but if
it generates XSL-FO, then it uses oxf:xslfo-serializer to generate a
PDF and sends that back to the browser with the HTTP serializer.

Makes sense.

I changed the page-flow to make it a view.

I changed the view to:

        <p:processor name="oxf:xslt">
                <p:input name="data" href="#instance"/>
                <p:input name="config">
                        <xsl:stylesheet version="2.0">
                                <xsl:template match="/">
                                        <fo:root>
                                                <fo:layout-master-set>
       
<fo:simple-page-master master-name="A4-portrait" page-height="29.7cm"
page-width="21.0cm" margin="2cm">
       
<fo:region-body/>
       
</fo:simple-page-master>
                                                </fo:layout-master-set>
                                                <fo:page-sequence
master-reference="A4-portrait">
                                                        <fo:flow
flow-name="xsl-region-body">
       
<fo:block>Hello, Bob!</fo:block>
                                                        </fo:flow>
                                                </fo:page-sequence>
                                        </fo:root>
                                </xsl:template>
                        </xsl:stylesheet>
                </p:input>
                <p:output name="data" ref="data"/>
        </p:processor>

And it just returned "Hello, Bob" on a simple XHTML page with page title
"XML Document".....??

  The drawback is that you are then stuck to oxf:xslfo-serializer
and you can not set any option of FOP.  If you want for example to
configure the fonts you want to use, you have to create your own
custom processor.

That's right. If the default settings don't work for you, then you can
in an XPL referenced from the page flow model="..." do the XSL
transformation generating XSL-FO, run the oxf:xslfo-converter and the
oxf:http-serializer. But in this case again, the XPL needs to be
referenced from the model, not the view.

Strange: if your view generates a document with fo:root as root
element, then it should go through the oxf:xslfo-converter. You can
investigate this by adding debugs in config/epilogue-servlet.xpl,
which does this. You will find it in orbeon-resources-private.jar.
Just copy it from there to your resources/config. The version you copy
in that directory will have precedence over the one in the jar file.

  Ok, thanks for the precision.  So let's say we have two pages in
the page flow, one with only a view, and the other with only a
model.  Is it correct to say that in the former case the epilogue
and so on will be called, and not in the later?  And that this is
why it is possible to do things like HTTP serialization right in the
model, but not in the view?

Alex,

Sorry about the lat reply to this. I should mention that I am using
Orbeon within Liferay so actually epilogue-portlet.xpl gets called
rather that epilogue-servlet and I notice there is no if case to detect
xsl-fo in that file.

What do you recommend?

then it should go through the oxf:xslfo-converter. You can investigate
this by adding debugs in config/epilogue-servlet.xpl, which does this.
You will find it in orbeon-resources-private.jar.
Just copy it from there to your resources/config. The version you copy
in that directory will have precedence over the one in the jar file.

I might be wrong about this but I would think portlet are designed to
generate HTML, and that if you need to have a dynamically generated
resource (PDF, image, zip...), you would just link to that resource
from your portlet and the link would go to a servlet that an
dynamically generate this resource.

Yes, you can. Because the HTTP Serializer writes to
ExternalContext.Response, which is an interface having different
implementations (in particular for servlets and portlets). But normally,
if you are producing content (HTML) which is part of the portlet and to
be included in the larger page, you would just use a view that produces
content and epilogue-portlet.xpl will do the serialization for you.
