Comaprison of Liferay ServiceBuilder to other Code generation tools like AndroMDA

阅读更多关于 Comaprison of Liferay ServiceBuilder to other Code generation tools like AndroMDA

I started digging into the liferay 6.x ServiceBuilder framework and really liked its code generation approach. A simple service.xml file can generate ready to use powerful services without even writing a single line of code. I also tried looking into AndroMDA which can generate similar services from the UML model, which sounds even more interesting since it will link my business model directly without me needing to learn a new xml config for service.xml (in case of liferay ServiceBuilder) now I am in the process of deciding which tool should I use. Based on your experience with any of these

How to use Liferay's permission system in other applications?

阅读更多关于 How to use Liferay's permission system in other applications?

问题 I'm considering using Liferay's permission system to implement access security in an external Java application (not a portlet). Liferay has robust features for managing users, groups, roles, permissions and resources. It would be great if I could leverage those instead of re-inventing the wheel in our external app. Liferay and our external application are configured to use the same CAS and LDAP for authentication, so they share the same users. So far I've successfully used Liferay's JSON-WS
