User development, A new message was posted in the thread "Network boundaries in JCA?": http://community.jboss.org/message/525750#525750 Author : Laird Nelson Profile : http://community.jboss.org/people/ljnelson Message: -------------------------------------------------------------- Ah, OK, now I get it.  That means the specification is +very+ badly under-specific about the contract that a connection handle must have with the caller.  It also means the specification is +very+ badly under-specific about the return values from methods on the connection factory.   What I mean is, if an application server is always going to provide a connection factory proxy (I assume you mean a java.lang.reflect.Proxy?), then any operations that the client performs +on+ that Proxy that return values +must+ return Serializable values.  That would, presumably, include the connection handle implementation.   This certainly follows, but it is not mentioned in the specification.  (Then again, neither is it mentioned that application servers will construct Proxy instances of the ConnectionFactory and ConnectionManager classes.)   I am talking about an application client, which is a "jee component" in a fully managed environment.   If only I could find Rahul Sharma and ask him these questions directly!  :-)   Best, Laird -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525750#525750
