Oracle Forms 11g - Security Warning:

Block potentially unsage components from being run?

Application: oracle.forms.engine.Main

Java has discovered application components that could indicate a security concern. Contact the application vendor to ensure that it has not been tampered with.

The application contains both signed and unsigned code.

Warning Reasons: When the jar file is NOT signed, then the following warning message will appear at time of Oracle 11g forms RUN.

Solution: Properly sign the JAR files.

Signing JAR file Procedure:
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

What is your first and last name?

  [Unknown]:  bishwanath das

What is the name of your organizational unit?

  [Unknown]:  development

What is the name of your organization?

  [Unknown]:  medi

What is the name of your City or Locality?

  [Unknown]:  dhaka

What is the name of your State or Province?

  [Unknown]:  dhaka

What is the two-letter country code for this unit?

  [Unknown]:  BD

Is CN=bishwanath das, OU=development, O=medi, L=dhaka, ST=dhaka, C=BD correct?

  [no]:  yes

Enter key password for < MediAlias>

        (RETURN if same as keystore password):

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
