You can use org.apache.fop.apps.Driver to get the
org.xml.sax.helpers.DefaultHandler and fire sax events on that. The
initialization code is highly order dependent.
// THIS IS JUST SOME SET UP CODE
// set up Logger
Hierarchy hierarchy = Hierarchy.getDefaultHierarchy();
PatternFormatter formatter = new PatternFormatter( "
[%{priority}]:%{message}\n%{throwable}" );
LogTarget target = new StreamTarget(System.out, formatter);
hierarchy.setDefaultLogTarget(target);
Logger log = hierarchy.getLoggerFor("fop");
// get output stream one way or
FileOutputStream out = new FileOutputStream( "filename.pdf" );
// HERE's THE CODE YOU NEED
Driver driver = new Driver();
driver.setOutputStream(out);
driver.setLogger( log );
driver.setRenderer( driver.RENDER_PDF );
DefaultHandler handler = (DefaultHandler) driver.getContentHandler() );
handler.startDocument();
...
handler.endDocument();
out.close();
After seeing Yuri's implementation I'd go with his. The above avoids
having to create a XML data file but you wind up with quite a bit of
wrapper code and loose the XSL template cache. However it is another
direct way, it also gives you a little more control since you are fireing
SAX events from Java rather than XSLT. Then again that kind of stuff
should probably be done in an extension.

Subject: RE: Question on XSLTInputHandler
Please respond to fop-dev
Before I go on, let me say I turned my XSLT-transformed document into a
string and then handed it to Fop.
XML tree -> Xalan transform handler -> serialize -> string -> Fop
However, this is silly.
It would be more intelligent to be able to send Sax events to Fop. I
found a class in the Fop source that handles it, but it seems to care
about Jim Clark's XML handlers. I use the Apache XML code and would
rather stick with those. I plan on looking into the Fop content handler
that claims need of Clark's stuff and see if it really cares, or
finding another content handler, or creating a regular Sax content
handler that can talk to Fop. Perhaps Cocoon has one since you can have
PDF generated at the end of a Cocoon pipeline. Does anyone know of one
that already exists?
