Oh,my God.I use in Chinese.Sorry. I think you can use cos.COSDocument for cache。
cache in memory: new COSDocument(new pdfbox.io.RandomAccessBuffer()) if you use PD,you can use PDDocument.load( new RandomAccessBuffer()) default is filesystem, at you temp dir or you set dir. called scratchFile in PDFBox,I think is cache mechanism . -- nisen(English Name)/倪森(Chinese Name) Blog: http://nisen.javaeye.com
