http://prdownloads.sourceforge.net/itext/itext-1.3.jarAjoutez-le au REPORTS_CLASSPATH.
2) Ajoutez pdfutils.zip au REPORTS_CLASSPATH. Ce fichier zip peut être extrait du fichier joint pdfcontact.zipp (changez d'abord l'extension du fichier de "zipp" à "zip") ou être construit à partir des sources Java fournies ci-dessous.
3) Ajoutez une nouvelle destination dans le fichier de configuration du Reports Server.
<destination destype="pdfconcat" class="pdfutils.PdfConcat">
</destination>
INSTRUCTIONS
Exécutez le rapport avec la syntaxe suivante
rwclient server=pdfconcat report=test.rdf destype=pdfconcat desname=;;; desformat=pdf
Exemple
rwclient server=pdfconcat report=test.rdf destype=pdfconcat desname=D:\ids10g\bin\hello.pdf;D:\ids10g\bin\tt.pdf;d:\ids10g\bin\watermark.jpg;D:\ids10g\bin\final.pdf desformat=pdfMISE EN GARDE : soutien Oracle
