Handle IPv6 link-local addresses correctly when used as bind addresses or multicast addresses
---------------------------------------------------------------------------------------------
Key: JGRP-977
URL: https://jira.jboss.org/jira/browse/JGRP-977
Project: JGroups
Issue Type: Feature Request
Affects Versions: 2.6.10, 2.4.6, 2.8
Environment: IPv6 addresses being used
Reporter: Richard Achmatowicz
Assignee: Bela Ban
IPv6 has two types of IP addresses: global addresses and non-global addresses.
Global addresses are unique across the internet (via judicious allocation of network prefixes by authorities). They make up the range 2000::/3 (2000:: to 3fff:ffff:ffff:ffff:ffff:ffff:ffff:ffff). Global addresses generally require no special treatment.
Non-global addresses, like link-local (fe80::/10) and site-local addresses (fec0::/10) are not guaranteed to be unique - in the extreme case, two interfaces on the same host can have the same link-local address. This means that they cannot be used on their own when binding to a socket, but must have extra information (a zone id or sometimes called scope) added to them to disambiguate them. The zone id is basically the interface you want the message to go out on.
A scoped link-local address is one which has a scope appended to it. The way to notate this is to append the scope to the link-local address after a % sign:
<link-local IP address>%<zone id>
where the zone Id can be numerical or simply the next name of the interface. For example, fe80::215:58ff:fec8:81a8%eth0.
A JGroups user may make use of link-local addresses when binding. In that case, we need to make sure that the scope is present, and if not, take some action. Otherwise, when binding to a socket with an unscoped link-local address, a SocketException will be raised.

[JBoss JIRA] Created: (JBAS-6820) MDBs are hard-coded to use jms-ra.rar

MDBs are hard-coded to use jms-ra.rar
-------------------------------------
Key: JBAS-6820
URL: https://jira.jboss.org/jira/browse/JBAS-6820
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: EJB3, JCA service
Affects Versions: JBossAS-5.1.0.Beta1
Reporter: Clebert Suconic
Assignee: Carlo de Wolf
Priority: Critical
We may have to deploy several resource-adapters for JBossMessaging. (Say.. remote servers, backup-servers and other configurations).
It seems that the JNDI for Inbound is simply ignored at some level. Instead of getting the spec Inbound from the JCA configured factory, EJB3 is hard-coding the dependency to the resource adapter and this is not acceptable for JBoss Messaging.
