In accordance with an embodiment, described herein is a system and method for multi-tenancy enablement of enterprise Java™ applications using resource proxies and application tenancy context. In according with an embodiment, the system and method can provide a plurality of deployable resources which can be used within the application server environment, and one or more application deployments, wherein each application deployment includes at least one of tenant-specific code and shared-tenant code. The system and method can further determine an application tenancy context of a thread, and point to one or more resource proxies, each of the one or more resource proxies being configurable to communicate with a tenant specific resource. Each of the one or more resource proxies can use the application tenancy context of a thread to communicate with a tenant specific resource.
