From 4ce2fbc415f2fae57842b2e13a0817bb63594434 Mon Sep 17 00:00:00 2001 From: tknall Date: Mon, 11 Jan 2010 10:58:48 +0000 Subject: - check implemented: responses are validated upon valid SL content (ErrorResponse, Create|VerifyXMLSignatureResponse) (ErrorCode 340) - new errorcode added (340: unable to receive suitable response) - default signature validation links changed (-> http://www.signaturpruefung.gv.at) - recognition of non-textual objects: static switch implemented allowing to configure behaviour (at compile time) in case of signatures (default behaviour: skip detection of all signatures as non-textual objects) - minor bug fixed: invalid evaluation of response charset resulting in invalid warn debug message - configuration updated - Default configuration updated git-svn-id: https://joinup.ec.europa.eu/svn/pdf-as/trunk@542 7b5415b0-85f9-ee4d-85bd-d5d0c3b42d1c --- .../wag/egov/egiz/pdf/AdobeSignatureHelper.java | 13 ++++++++++--- .../knowcenter/wag/egov/egiz/pdf/ObjectExtractor.java | 17 ++++++++++++++--- .../wag/egov/egiz/sig/connectors/bku/BKUHelper.java | 19 ++++++++++++++++--- .../egiz/sig/connectors/bku/BKUPostConnection.java | 9 ++++----- 4 files changed, 44 insertions(+), 14 deletions(-) (limited to 'src/main/java/at/knowcenter/wag') diff --git a/src/main/java/at/knowcenter/wag/egov/egiz/pdf/AdobeSignatureHelper.java b/src/main/java/at/knowcenter/wag/egov/egiz/pdf/AdobeSignatureHelper.java index db5b082..1db1de0 100644 --- a/src/main/java/at/knowcenter/wag/egov/egiz/pdf/AdobeSignatureHelper.java +++ b/src/main/java/at/knowcenter/wag/egov/egiz/pdf/AdobeSignatureHelper.java @@ -110,7 +110,14 @@ public class AdobeSignatureHelper { // Standard filter // sig.setLocation("location is not visible");
