From 03875a41dd5b065c8ab0c04268ac9371f51a8639 Mon Sep 17 00:00:00 2001 From: tknall Date: Wed, 4 Feb 2009 09:10:02 +0000 Subject: Some more log messages (e.g. encoding related issues). Updating web application (in external invocation mode) enhancing support for being used within an iframe. Two new (optional) parameters for external invocation mode: locale: defines the locale being used for webapp (e.g. locale=de or locale=de_DE), invoke-app-error-url: can be used to declare a callback url to the calling web application in order to transfer error messages from pdf-as. In case of error pdf-as redirects the user to the error-page-url (if given) providing the error and the cause in url encoded parameters ("error", "cause"). Formatter for mocca signature params enhanced. git-svn-id: https://joinup.ec.europa.eu/svn/pdf-as/trunk@323 7b5415b0-85f9-ee4d-85bd-d5d0c3b42d1c --- .../java/at/gv/egiz/pdfas/utils/ConfigUtils.java | 3 ++ .../egiz/pdfas/web/helper/SignServletHelper.java | 39 ++++++++++++++--- .../java/at/knowcenter/wag/egov/egiz/PdfAS.java | 2 +- .../wag/egov/egiz/cfg/SettingsReader.java | 1 + .../egov/egiz/sig/connectors/bku/BKUHelper.java | 1 + .../mocca/LocRefDetachedMOCCAConnector.java | 6 +-- .../egiz/sig/sigid/DetachedMOCIdFormatter.java | 2 +- .../wag/egov/egiz/web/ExternAppInformation.java | 6 +++ .../knowcenter/wag/egov/egiz/web/FormFields.java | 2 + .../wag/egov/egiz/web/SessionAttributes.java | 5 +++ .../wag/egov/egiz/web/servlets/DataURLServlet.java | 2 +- .../egov/egiz/web/servlets/ProvidePDFServlet.java | 2 +- .../wag/egov/egiz/web/servlets/SignServlet.java | 3 +- src/main/webapp/css/pdfas-styles.css | 1 + src/main/webapp/jsp/error.jsp | 44 +++++++++++++++++-- src/main/webapp/jsp/null_request_page.jsp | 51 +++++++++++++++------- src/main/webapp/jsp/redirect_to_parent.jsp | 24 ++++++++++ src/main/webapp/sitemesh/standalone.jsp | 14 +++++- src/site/changes.xml | 14 +++++- 19 files changed, 187 insertions(+), 35 deletions(-) create mode 100644 src/main/webapp/jsp/redirect_to_parent.jsp (limited to 'src') diff --git a/src/main/java/at/gv/egiz/pdfas/utils/ConfigUtils.java b/src/main/java/at/gv/egiz/pdfas/utils/ConfigUtils.java index a7bca3f..34de789 100644 --- a/src/main/java/at/gv/egiz/pdfas/utils/ConfigUtils.java +++ b/src/main/java/at/gv/egiz/pdfas/utils/ConfigUtils.java @@ -260,6 +260,7 @@ public final class ConfigUtils { String infoConfiguration = " configuration path = \"" + SettingsReader.CONFIG_PATH + "\""; String infoCertStore = " certstore path = \"" + SettingsReader.CERT_PATH + "\""; String infoTempPath = " temporary path = \"" + SettingsReader.TMP_PATH + "\""; + String encoding = " file.encoding = \"" + System.getProperty("file.encoding") + "\""; if (logger != null) { logger.info(separator); @@ -267,6 +268,7 @@ public final class ConfigUtils { logger.info(infoConfiguration); logger.info(infoCertStore); logger.info(infoTempPath); + logger.info(encoding); logger.info(separator); } else { StringBuffer buffer = new StringBuffer(); @@ -275,6 +277,7 @@ public final class ConfigUtils { buffer.append(infoConfiguration).append(SystemUtils.LINE_SEPARATOR); buffer.append(infoCertStore).append(SystemUtils.LINE_SEPARATOR); buffer.append(infoTempPath).append(SystemUtils.LINE_SEPARATOR); + buffer.append(encoding).append(SystemUtils.LINE_SEPARATOR); buffer.append(separator); System.out.println(buffer.toString()); } diff --git a/src/main/java/at/gv/egiz/pdfas/web/helper/SignServletHelper.java b/src/main/java/at/gv/egiz/pdfas/web/helper/SignServletHelper.java index 6fc7a1a..113169c 100644 --- a/src/main/java/at/gv/egiz/pdfas/web/helper/SignServletHelper.java +++ b/src/main/java/at/gv/egiz/pdfas/web/helper/SignServletHelper.java @@ -12,10 +12,12 @@ import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; +import javax.servlet.http.HttpSession; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; +import at.gv.egiz.pdfas.api.commons.Constants; import at.gv.egiz.pdfas.framework.SignatorFactory; import at.gv.egiz.pdfas.framework.signator.Signator; import at.gv.egiz.pdfas.impl.output.ByteArrayDataSink; @@ -33,6 +35,7 @@ import at.knowcenter.wag.egov.egiz.sig.connectors.bku.SignSignatureObject; import at.knowcenter.wag.egov.egiz.web.FormFields; import at.knowcenter.wag.egov.egiz.web.LocalRequestHelper; import at.knowcenter.wag.egov.egiz.web.PDFContainer; +import at.knowcenter.wag.egov.egiz.web.SessionAttributes; import at.knowcenter.wag.egov.egiz.web.servlets.ProvidePDFServlet; /** @@ -148,7 +151,7 @@ public class SignServletHelper si.output = TempDirHelper.createTempDataSink(si.filename + "_signed.pdf"); signator.finishSign(si.si, si.output); - returnSignResponse(si, response); + returnSignResponse(si, request, response); log.debug("finishSign finished."); //$NON-NLS-1$ } @@ -158,12 +161,13 @@ public class SignServletHelper * * @param si * SessionInformation. + * @parem request The servlet request. * @param response * The servlet response. * @throws IOException * The IO Exception. */ - public static void returnSignResponse(SignSessionInformation si, HttpServletResponse response) throws IOException + public static void returnSignResponse(SignSessionInformation si, HttpServletRequest request, HttpServletResponse response) throws IOException { // SignResult sign_result = si.sign_result; @@ -194,7 +198,13 @@ public class SignServletHelper } else { - // TODO @tzefferer: what is this code? + /** + * The following code handles an external invocation of pdf-as.
