hi all, i have a SFSB(v3.0) running in JDeveloper embedded oc4j ejb container. it runs fine with multi-user enviroment. but when it runs timeout or the @remove method gets called explicitly, it always throw NoSuchObjectException, even i try to create a new SFSB object by access the server on another client. my environment is JDev 10.1.3 with embedded oc4j from the debug window, i can see at any circumstances every client gets the same object (i did see it from its id property), would it be anything i need to set in the configuration? anyone familiar with this problem? Thanks, Edward P.S. the same code will run well in JBoss with default config
