JFox Feature1.following ejb 2.0 sessionbean specification, not supporting entitybean temporarily, recommending scheme of using SessionBean + DAO/OR to implement data persistence. 2.adopting improved jmx kernal which is suitable for development of middleware product , simplfying old kernal and doing some enhancement in expansibility and maintenance of develop logic. 3.supporting JTA1.01specification and 2pc completely. 4.supporting data source 5.switching remote invocation and local invocation automaticly . When invocation occurs between ejbs in same application server, local invocation would be selected. It is not neccessory to implement local interface. 6.adopting automatic proxy invocation framework. 7.automatic delivering only need copy. When deploy new ejb module , work only be done is copying jar package of ejb into %JFOX_HOME%/deploy directory. The automatic deliver processor will deloy eib into appplication server soon. 8.using meta as deploy description file. Deployment using meta on longer need complex step and corperation among all part . deploy description can be done by programer . 9.post-determine invocation mode post-determine invocation mode means invocation protocol can be determined dynamicly in invocate process. User can get home stub which isn't pinned with protocol through jndi.lookup. when client invocate method using this stub, a suitable protocol will be selected. Local invocation can be selected for invocation in same jvm while JRMP protocol can be selected for remote invocation. User can also determine using JRMP for invocation in same jvm through Home.setProtocol method. 10.a refined invocation interceptor chain will be used to promote velocity of process on server. Otherwise，JFox include other characteristic： 。有很多可以单独使用的部件:如JMX,JNDI,EJB等,又有一个完整的J2EE解决方案:JFox. 这样用户就可以自己组装所需要的解决方案,而不是一定要选择大而全的J2EE应用服务器,并可将这些部件整合进自己的产品和项目中. 。System Kernel:JFoxKNL ,can 可作为很多J2EE应用的核心加以扩展 。可扩展互操作框架 。可以预先装载所有服务或提供按需装载的方式。 。JFox采用层次化的设计结构 。JFox的服务通过JMX进行统一管理。 。Integration Orbas Kernel,will released with JFox2.0 。Integration Tomcat,Jetty,will released with JFox1.0 |
