pdf output from java code
Hi,
I'm using JasperReports, which generates PDF and other reports from XML
descriptions.
I'm able to run it inside cocoon, to produce reports that I save to files.
However I want to display them on-line.
My general question is, I want to run java code inside a XSP, but instead
of returning XML, that code generates binary info that I want to stream to
the browser.
Is XSP the way to go ?
thanks
Ricardo

Hi ,
It will be helpful to others if you can give the configuration required to
work with JasperReports in Cocoon.

well, I wondered the same and didn't find an explanation for it... could you
spare some time to investigate the matter ?
I apologize for not being of much assistance... right now I'm horribly
busy... this will be the second working-weekend in a row :(

Many thanks, Luca.
It was the problem ! But I really don't
understand why the sql namespace declaration and
the namespace prefix don't appear in the resulting
XML code (I mean, if I take a snapshot before the
XSLT transformation). Does Cocoon hide it ?

David,
may you try prefixing the elements produced by SQLTransformer with the
"sql:" namespace in your XSL (like in: <xsl:template
match="table/sql:rowset">) ?

CIncludeT-SQLT- XSLT
Posted by David LAGARDERE <dl...@yahoo.fr>.
Hello.
I got more details about what I thought being
an error with Xalan and XPath.
What I'm doing is getting data from a main XML file
including other XML files containg SQL requests with
the cinclude::include. These requests are processed in
another pipeline and SQL data is retrieved thanks to
the SQL Transformer and xml serialized. I finally get
the resulting data from the "SQL pipeline" in the
first pipeline (thanks to the CInclude transformer)
which is passed to an XSLT transformer and html
serialized.
My problem is that the resulting XML is not processed
by XSLT as expected :
==> Main XML page <==
<?xml version="1.0" encoding="UTF-8"?>
<search
xmlns:ci="http://apache.org/cocoon/include/1.0">
<ci:include src="cocoon:/sql/table.xml"/>
</search>
==> Resulting XML <==
<search>
<table>
<rowset>
<!-- Some data fetched by the SQL transformer -->
</rowset>
</table>
</search>
==> XSL applied <==
<xsl:template match="search">
<!-- Some HTML -->
<xsl:apply-templates select="table/rowset">
<!-- Some HTML -->
</xsl:template>
<xsl:template match="table/rowset">
<!-- Some HTML -->
</xsl:template>
The (bad) result I get is that the "table/rowset"
template is never reached !
Here is the sitemap :
<map:pipelines>
<map:pipeline>
<map:match pattern="sql/**.xml">
<map:generate src="xml/sql/{1}.xml"/>
<map:transform type="sql">
<map:parameter name="use-connection"
value="personnel"/>
<map:parameter name="show-nr-of-rows"
value="false"/>
</map:transform>
<map:serialize type="xml"/>
</map:match>
</map:pipeline>
<map:pipeline>
<map:match pattern="**.xml">
<map:generate src="xml/{1}.xml"/>
<map:transform type="cinclude"/>
<map:transform src="xsl/{1}.xsl" type="xslt"/>
<map:serialize type="xml"/>
</map:match>
</map:pipeline>
</map:pipelines>
NB:the same happens if I use one pipeline
and three matchers
I really some help to get around this...
Thanks in advance
David LAGARDERE

Do you want to buffer whole PDF in memory? What if it is huge? Reader
will allow you to send parts of PDF as soon as this part is done.

Hi,
Wouldn't it still make more sense to use the action to generate it and the
reader to display it ?
I'm assuming actions can place stuff somewhere that's accessible to
readers... the pipeline ??

RE: pdf output from java code

ok,
I think I'll follow the action + reader path. Do I have to implement a
custom reader ?
I never want the PDF to exist as a file, I want to generate it and deliver
it on the fly.
I'll give back any code I write.

No.
XSP must generate XML. You could generate XHTML with link to required
PDF or do a redirect with META or Javascript.
Better way will be to code an action, and have map:read nested into it
which will serve generated file.
