Installation

grails install-plugin license

Usage

• Generate license file:

grails generate-license

• Start app:

grails run-app

• Instal/verify license at http://localhost:8080/your_app/license. If you try to access your app without installing license, you will be redirected to this page.

Components

• /plugins/license-0.1/etc/privateKey.store - private key file. This never gets included in your WAR. (You should generate your own private/public keys with keytool command. see tips section below)
• /plugins/license-0.1/etc/LicensePrivateConfig.properties - holds all necessary configuration to create a license such as issuer, holder, validity etc. Again not included in WAR
• /plugins/license-0.1/conf/publicCerts.store - public key file. This is included in WAR
• /plugins/license-0.1/conf/LicensePublicConfig.groovy - holds all necessary information required for the client. Included in WAR
• /plugins/license-0.1/controller/LicenseController - Install, verify license
• /plugins/license-0.1/services/LicenseService - Install, verify license
• /plugins/license-0.1/conf/LicenseFilter - defines which controllers, actions need to be protected.

Tips

• To generate private key:

keytool -genkey -alias privatekey -keystore privateKeys.store

• To generate public key

keytool -export -alias privatekey -file certfile.cer -keystore privateKeys.store
keytool -import -alias publiccert -file certfile.cer -keystore publicCerts.store

• The system preferences are stored in the registry in windows and file system (/etc/.java/) in Linux. You may need appropriate permissions to be able to do this.
