[iText-questions] Concat pdf

[J�r�me Keirse]

Hi,   I was using IText java API with sucess for several months. I have to concatenate a lot of pdf files and I'm getting an error I can't resolve :   I have got to scan several folders which contains pdf files and I have to concatenate all the pdf files for each folder. After some concat-pdf were sucessfull created I'm randomly get the following exception (but it seems to be after around 1000 concatenations) :   java.io.FileNotFoundException : folder100/afile.pdf (too many open files)     at java.io.RandomAccessFile.open(Native Method)     at java.io.RandomAccessFile.<init> (RandomAccessFile.java : 200)     at java.io.RandomAccessFile.<init> (RandomAccessFile.java : 94)     at com.lowagie.text.pdf.RandomAcessFileOrArray.<init> (Unknown Source)     at com.lowagie.text.pdf.PRTokeniser.<init> (Unknown Source)     at com.lowagie.text.pdf.PdfReader.<init> (Unknown Source)     at com.lowagie.text.pdf.PdfReader.<init> (Unknown Source)     at com.test.PDF.concatPDF (MyFile.java : 200)   I tried to release my IText object by several ways (obj.close(), obj = null, System.gc()), but without any results.   Is there a limit with the concat ? (I don't think ...) but are the files opened by the PdfReader object closed correctly ?   Any ideas? Thanks - J�r�me
