隨著JPA得到眾多廠商和開發人員的認同, 如同 Resin 的新聞中所說的那樣:

2007-07-18 Resin 3.1.2 adds significant features

Resin 3.1.2 now includes an implementation of the Java Persistence API, which is a major feature of the Enterprise Java Beans 3.0 standard. New features have also been added to the Hessian 2.0 web services protocol that allow for better security and message compression. Resin's JAX-WS support continues to improve with better support for WSDL handling and handler chains. Both Resin and the Quercus Java-PHP engine also underwent major reliability tests making them even more solid than before.

"Before JPA, developers had to choose from an array of non-standard, incompatible API's to do object persistence. JPA standardizes this fundamental task and makes it easier for developers to get their applications written faster. Resin's JPA implementation is efficient and reliable, so our customers can start using this exciting new standard right away," said Emil Ong, Software Engineer at Caucho Technology.

Resin 的最新版也開始支持內置的 JPA 了. 像上面這段話上所說, JPA 最大的優點就是把開發人員從各種各樣的包和API中解放出來, 例如你的程序不再需要導入 org.hibernate.*** 或者 com.oracle.***, 而且便于隨時切換底層引擎. 這就像 JDBC 所起的作用那樣.

PS: Resin 是另一款性能和易用性上都超過 Tomcat 的 Java Web 服務器, 同時也支持 Java 實現的 PHP. 雖然 Tomcat 是標準的實現, 但是 Resin 在很多地方都比 Tomcat 優秀.
