I have tried the plugin with both grails 1.0.1 and 1.0.2 and works fine. Can you try the plugin with a simple HelloWorld app? If you still have problems, let me know your OS, java ver etc BTW, the plugin has already been added to grails repo. You should be able to install the plugin by <i>grails install-plugin license</i>. - Mano The exception indicates that probably there is a conflicting jar.

However, I basically run into two problems: - If I generate a license with the key pair that comes with the plugin, the license won't be accepted and the following exception is thrown: service.LicenseService License could not be installedde.schlichtherle.xml.PersistenceServiceException: java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserFactoryImpl . Usually, I would assume this is due to conflicting xercesImpl.jarS. However, in my app there is only one, that is the one that comes with Grails 1.0.2 - After having generated my own private / public key pair and changing the config settings accordingly, 'grails generate-license' simply prints out 'null', which seems to originate from line 68 in GenerateLicense.groovy: LicenseManager lm = new LicenseManager(licenseParam). I have double-checked the settings in conf/LicensePublicConfig.groovy and etc/LicensePrivateConfig.properties. -- Best regards, Bjoern Wilmsmann PS: Besides, this plugin should definitely be added to the official Grails plugins page, as it provides a very useful feature.
