JCA ??

[ruhail akhtar]

Hi all,
Can JCA adaptor be a tcpip client? That means that it should have connection to the tcpip server and connection should always be up. I get confused when they talk about JCA adapter is standard for connecting to legacy systems such as Databases and yet it can implement any propietery protocal. Additionally can JCA adapter have inbound queue and outbound queue listening to same socket connection and yet serving one client (session bean). If there is alternative to JCA please write.
Thanks,
