[jboss-jira] [JBoss JIRA] Commented: (JGRP-818) JChannelFactory fails to parse configuration and gives a contradictory error message

    [ https://jira.jboss.org/jira/browse/JGRP-818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12428971#action_12428971 ] 

Vladimir Blagojevic commented on JGRP-818:
------------------------------------------

There is no such class as JConfigurationFactory; I believe you are referring to JChannelFactory, correct? JChannelFactory was not designed to use file that accepts file format that contains <protocol_stacks> as a top element. In 2.6 release configuration file that used <protocol_stacks> as a top element was a multiplexer channel setup. In order to use this file format you have to invoke one of the JChannelFactory#setMultiplexerConfig() methods. JChannelFactory , as is, is designed to use a file format that has a <config> as an enclosing element and contains only one channel configuration. 

I agree with you that this is all a bit confusing. Will consult within our team how to resolve this in 2.7 release.

> JConfigurationFactory gives the following error message when parsing the attached configuration file:
> {noformat}
> invalid XML configuration: XML protocol stack configuration does not start with a '<config>' element; maybe the XML configuration needs to be converted to the new format ?
> use 'java org.jgroups.conf.XmlConfigurator <old XML file> -new_format' to do so
> {noformat}
> The attached file does indeed start with a 'config' element.  Looking at the code, JConfigurationFactory is actually looking for a 'protocol_stacks' root element.
> the error message in JConfigurationFactory should be fixed.  
> Furthermore, the -new_format argument doesn't appear to be accepted by XmlConfigurator.  XmlConfigurator also seems to like the XML file if it starts with <config>.  So which is the right format?  All of the examples provided with the distribution start with <config>.
