Oracle Forms 11g: Signing JAR file

Step-1: Create Keystore (keytool)
Before sign a JAR file we need a keystore. we can create it using the keytool utility. The keytool utility is normally found under the JDK bin directory.

1.1 Navigate the Directory-

C:\>cd C:\Oracle\Middleware\Oracle_FRHome1\jdk\bin

1.2 Generate keystore
C:\Oracle\Middleware\Oracle_FRHome1\jdk\bin>keytool -genkey -alias MediAlias -keyalg RSA -keystore MediStore

Enter keystore password:  medipassword

Step-2: sign JAR file(jarsigner)

Once the keystore is created, we can use the jarsigner utility to sign the JAR files. The jarsigner utility is normally found under the JDK bin directory.

C:\Oracle\Middleware\Oracle_FRHome1\jdk\bin>jarsigner -keystore MediStore -storepass medipassword C:\ Oracle\Middleware\Oracle_FRHome1/forms/java/clientinfos.jar MediAlias
