Jette un coup d'oeil à http://jasperreports.sourceforge.net/

Cela te permet de générer des rapports en PDF. C'est basé sur des
template que tu "remplis" ensuite avec tes données. Il existe plusieurs
outils GUI te permettant de générer ces templates.

Je trouve que c'est plus pratique à utiliser que XSL-FO mais ça ne
respecte pas de norme.

Depuis word 2003 on peut mettre un document word au format XSL-FO (n'ayant
pas word 2003, je n'ai pas encore essayé)
http://msdn.microsoft.com/office/default.aspx?pull=/library/en-us/odc_wd2003_ta/html/OfficeWordWordMLtoXSL-FO.asp&print=true

perso, j'ai choisi d'ecrire du docbook (a l'aide de org.jdom)
le docbook on peut pas faire plus simple (genre html 2.0).
de transformer le docbook en xsl-fo par les feuilles xslt qui existent.
ensuite le fo est soit :
- affiche a l'ecran
- transforme en pdf
- transforme en html 3.2
...

voici ce que j'ai ecrit, la seule chose a changer est l'appel a
limsPreferencesFacade, et l'appel a la feuille xsl est chez moi :
/usr/share/xml/docbook/stylesheet/nwalsh/current/fo/docbook.xsl

note : ca gere aussi les codes barres avec chrysalis.
un petit truc fatiguant c'est le lien entre les fichiers generes :
un fichier html (ou plusieurs), les images ...
il faut donc faire des liens relatifs.
par contre pour faire le pdf (ou tout est dedans), il faut des liens
relatif. le but de code qui gere les codes barres gere ce probleme.

Merci, ça a effectivement l'air très intéressant.
Pour l'instant, j'en suis à la phase de conception de l'application et je
n'ai donc pas vraiment le temps d'approfondir mais je prépare le terrain
pour la réalisation et je ne manquerai pas d'étudier ça.

Merci beaucoup pout tout ça, je regarderai très en détail dans quelques

La deuxième solution est utilisée par l'administration de mon canton dans le
logiciel de saisie des impôts pour imprimer la déclaration. Je trouve que
c'est une excellente solution mais elle m'inquiète techniquement.

La première solution n'est pas valable pour du print, et il n'existe pas
de solution standard robuste et gratuite pour la troisième (voir quand
meme POI d'Apache- http://jakarta.apache.org/poi/ -, mais je crois
l'implémentation du format MS Word est super limitée, le support d'Excel
est bon par contre).

Le plus efficace sera la génération d'un fichier PDF à partir d'un
XSL:FO généré par transformation à partir de données XML (voir FOP
d'Apache : http://xml.apache.org/fop).

Si tu as de bonnes bases en XML/XSL, ça ne devrait pas te poser de
problèmes, c'est assez facile à implémenter, surtout pour de petites
éditions de quelques pages.

Pas vraiment le choix pour faire ça gratuitement avec Java. A moins de
recourir à une fusion de fichier RTF, qui reste super limitée et peu
portable.
