是的你可以 对于在JDK 5或更高版本上运行的任何app-server / Tomcat，它都是可移植的。
功能
* Fully certified JAX-RS implementation
* Portable to any app-server/Tomcat that runs on JDK 5 or higher
* Embeddedable server implementation for junit testing
* Client framework that leverages JAX-RS annotations so that you can write HTTP clients easily (JAX-RS only defines server bindings)
* Client "Browser" cache. Supports HTTP 1.1 caching semantics including cache revalidation

从网站获得的jar是使用Java 1.6编译的（至少是2.1.0.GA版本）。这里的关键术语是“可移植的”，我解释为你必须从头开始重新编译项目以获得1.5版本。
