Hi Bruno,
Thanks a lot for your quick reply.
I am generating 2 separate files USING iText. I am merging them later.
The first file is always getting generated. But the second file gets
generated MOST OF THE TIMES..but sometimes it gives the error.
I am closing the documents and also not adding any junk.
I am using page event which puts page numbers and some footer labels.
I am enclosing the file which has the code for generating both the files and
also the method which merges.
method, downloadLicencePdfInline - calls the PDF generation methods
separately and merges
method, generateNoticeOfDecisionPdf - second PDF which GIVES ERROR SOMETIMES
method, generateLicencePdf - first PDF which DOES NOT GIVE ERROR
Regards,
Archana
