Extend the Self Signing Certificate date of jar-files in Forms11gRelease2

Re-Sign Expired Jar-Files and Extend the Self Siging Certificate. réf Oracle (Doc ID 760815.1)
When you launch the java-control panel, you will see that the forms’certicate date is expired on july 6, 2013

Remove the old jar file’ signature of Self Signing Certificate

First, begin by setting some local environment variables, we will do the test on WindowsXp machine
set JAR_PATH=C:\Oracle\Middleware\Oracle_FRHome1\forms\java
set UNSIGN_JAR_PATH=C:\LineCode_Projects\UnsJar
set JAVA_PATH=C:\Oracle\Middleware\Oracle_FRHome1\jdk\bin

• Copy each jar file from your %JAR_PATH% into a new folder let’s say C:\LineCode_Projects\UnsJar
• Run the command :          jar xf jarfilename.jar

# Remove the formsGraph.jar’ signature
Run the command :         %JAVA_PATH%jar xf formsGraph.jar

 This, will extract META-INF folder and com folder

• Remove the META-INF folder and the jar file
• Recreate your jar file by running the command jar -cvf jarfilename *.*
• copy the new jarfilename jar-file into your %JAVA_PATH% folder

# Read the MANIFEST.MF -file
type META-INF\MANIFEST.MF

Repeat the steps for each jar-file refrecend if your formsweb.cfg configuration file

# Forms applet archive setting for other clients (Sun Java Plugin, Appletviewer, etc)
archive=frmall.jar,FormsGraph.jar

Sign the jar-files and extend the expired self certificate referenced in the formsweb.cfg configuration file
Add the following environment variable to point the sign_webutil.bat script location
set FORMS_ORACLE_INSTANCE=C:\Oracle\Middleware\asinst_1

Edit your sign_webutil.bat-script and change the following values to generate new certificate.
Change the values as in the following example:

SET DN_CN=LineBCode Management
SET DN_OU=SalemBDevTools
SET DN_O=LineCodeBOracle
SET DN_C=CA
REM
REM Give your keystore file
SET KEYSTORE=”%HOMEDRIVE%%HOMEPATH%/.keystore”
REM
REM If KEYSTORE already exists, old KEYSTORE_PASSWORD for the keystore file must
REM be correctly given here. If KEYSTORE does not already exist, any password
REM given here will be taken for the new KEYSTORE file to be created.
REM
REM *** Remove the text after the ‘=’ below and replace with your password. ***
SET KEYSTORE_PASSWORD=yourpassword
REM
REM Give your alias key here.
REM
SET JAR_KEY=linecodeKey
REM
REM Key Password for the given key to be used for signing.
REM
REM *** Remove the text after the ‘=’ below and replace with your password. ***
SET JAR_KEY_PASSWORD=yourpassword
REM
REM Number of days before this certificate expires
REM
SET VALIDDAYS=2160

Issue to the following command to sign the specified JAR file.

cd %JAR_PATH%
%FORMS_ORACLE_INSTANCE%/bin/sign_webutil.bat jacob.jar

Verify the status the jar files.

# Run the following command
cd %JAR_PATH%
%JAVA_PATH%/jarsigner -verify appicons.jar

 Verify the end date of the signed jar-files

Let’s extract the frmwebutil.jar into the %UNSIGN_JAR_PATH% folder
%JAVA_PATH%/jar xf frmwebutil.jar
# META-INF folder’s content

# Print the L_WEBUTI.DSA content
%JAVA_PATH%/keytool -printcert -file META-INF/L_WEBUTI.DSA > META-INF/result.txt
