[JBoss JIRA] Commented: (JBAS-7818) RMIAdaptor replacement based on JSR160

by Scott Marlow (JIRA)

[ https://jira.jboss.org/browse/JBAS-7818?page=com.atlassian.jira.plugin.sy... ] Scott Marlow commented on JBAS-7818: ------------------------------------ Shelly, JBAS-7828 was considered low priority, it could be done but doesn't have to be. For IPV6 support, that deserves a separate jira. Lets talk about it on Monday or create a new jira and assign to me. JMXServiceURL wants square brackets around the IPV6 numeric address and that will help (as per http://www.ietf.org/rfc/rfc2732.txt). > RMIAdaptor replacement based on JSR160 > -------------------------------------- > > Key: JBAS-7818 > URL: https://jira.jboss.org/browse/JBAS-7818 > Project: JBoss Application Server > Issue Type: Task > Security Level: Public(Everyone can see) > Components: JMX > Reporter: Scott M Stark > Assignee: Scott Marlow > Fix For: TBD-6.x > > > A replacement for the proprietary RMIAdaptor is needed that supports authentication, authorization and SSL. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

If I don't report the issues correctly, pls help correct me. I develop a stateless session bean, in which EJB2.x and EJB3 interfaces coexist. In short, it works, but with two issues. 1. unable to override 2.x local home jndi name. In jboss.xml (jboss_5_0.dtd), the local home jndi is NOT allowed, so you have to refer to the default local home jndi -- beanName/local 2. when calling method on remote business interface, it works, but EJB exception is thrown by javax.ejb.EJBLocalObject.isIdentical. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
