YaHP is a java library which permits to convert an html document into a pdf document.

YaHP is licensed under the LGPL (GNU).

YaHP use a pluggable renderer system. It has currently 3 renderer, each of them carrying advantages and disadvantages.

The swing renderer, most stable, good rendering, can set header/footer, choose page size.
The OpenOffice.org renderer, average rendering, cannot set header footer nor page size.(worst renderer)
The firefox renderer, best rendering, can set header/footer, choose page size, must patch and compile a version of firefox, tested only on linux. Download pre-compiled version of the patched firefox (compiled on ubuntu dapper)mozila-print.tar.gz (08/04/2006)

To use the openoffice.org renderer, you must first launch openoffice in listen mode like this:

oowriter "-accept=socket,port=8100;urp;"

(with the quotes), then set the correct properties (see CSimpleConversion.java).

To use the firefox renderer, you must first download the firefox source : firefox-1.5.0.1-source.tar.bz2 at http://www.mozilla.org/ , then patch it with the files "layout.printing.nsPrintEngine.diff" and "layout.printing.nsPrintEngineH.diff", then compile it by issuing :

"./configure --prefix=/yourchoosenpath/mozilla-print/ --disable-logging --disable-tests --disable-oji --disable-view-source --disable-accessibility --disable-composer --disable-ldap --enable-canvas --disable-gnomeui --enable-application=browser --with-user-appdir=.print.mozilla --enable-system-cairo", then "make install"

Copy the sh script "fireprint" in /yourchoosenpath/mozilla-print/, modify the path inside the script, then set the correct properties (see CSimpleConversion.java). --script refer to the path /yourchoosenpath/mozilla-print/fireprint.

You also need ps2pdf installed and in the path.
