I don't have any issue. I've just finished signing 1000 docs, each 10M
in size without any problem. I used this code:
for (int k = 0; k < 1000; ++k) {
KeyStore ks = KeyStore.getInstance("pkcs12");
ks.load(new FileInputStream("c:\\certvery2.pfx"),
"password".toCharArray());
String alias = (String)ks.aliases().nextElement();
PrivateKey key = (PrivateKey)ks.getKey(alias,
"password".toCharArray());
Certificate[] chain = ks.getCertificateChain(alias);
PdfReader reader = new PdfReader("c:\\smith.pdf");
FileOutputStream fout = new FileOutputStream("c:\\smith_sig.pdf");
PdfStamper stp = PdfStamper.createSignature(reader, fout, '\0');
PdfSignatureAppearance sap = stp.getSignatureAppearance();
sap.setCrypto(key, chain, null,
PdfSignatureAppearance.VERISIGN_SIGNED);
sap.setReason("I'm the author");
sap.setLocation("Lisbon");
sap.setVisibleSignature(new Rectangle(100, 100, 300, 200), 1, null);
stp.close();
System.out.println("Sign " + k + " Mem " +
Runtime.getRuntime().freeMemory());
}
Using Sun's jdk in windows 1.4.2_05b with -mx128m.
Unless you produce code and a pdf so that I can reproduce the problem I
believe the case is closed.
