Please dont suggest me to use WS to call the service, I want to try the RMI before trying for WS. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/724385#724385] Start a new discussion in JBoss ESB Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
