Subject [jira] [Commented] (FLEX-34886) BlazeDS 4.7.0 incompatible replacement for BlazeDS 4.6
Date Tue, 30 Jun 2015 15:31:05 GMT

    [ https://issues.apache.org/jira/browse/FLEX-34886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14608496#comment-14608496
] 

Alex Harui commented on FLEX-34886:
-----------------------------------

Apache Flex's version of BlazeDS switched to ActiveMQ because it is under an Apache-compatible
license.  The Adobe versions of BlazeDS used a Sun-licensed dependency which is not allowed
under Apache rules.  It might be possible to abstract the dependency in order to allow folks
to easily switch back to the Sun version.  Patches to make that happen are welcome.

>             Project: Apache Flex
>          Issue Type: Bug
>          Components: BlazeDS
>    Affects Versions: BlazeDS 4.7

> I've recently noticed that Apache BlazeDS 4.7.0 has become available and have attempted
to migrate a project currently using Adobe BlazeDS 4.6.
> Although the release notes state that there are no changes from Adobe BlazeDS 4.6 there
seems to be some significant differences. I am encountering an exception related to the messaging
system:
> java.lang.NoClassDefFoundError: javax/jms/InvalidSelectorException
> 	at flex.messaging.services.MessageService.testSelector(MessageService.java:1182) ~[flex-messaging-core-4.7.0.jar:4.7.0]
> 	at flex.messaging.services.MessageService.manageSubscriptions(MessageService.java:930)
~[flex-messaging-core-4.7.0.jar:4.7.0]
> 	at flex.messaging.services.MessageService.serviceCommand(MessageService.java:339) ~[flex-messaging-core-4.7.0.jar:4.7.0]
> 	at flex.messaging.MessageBroker.routeCommandToService(MessageBroker.java:1573) ~[flex-messaging-core-4.7.0.jar:4.7.0]
> 	at flex.messaging.endpoints.AbstractEndpoint.serviceMessage(AbstractEndpoint.java:1016)
~[flex-messaging-core-4.7.0.jar:4.7.0]
> ...
> The exception seems to be getting thrown from the "testSelector" method on line 1182
in flex.messaging.services.MessageService.java when it tries to instantiate a new flex.messaging.services.messaging.selector.JMSSelector
> I've noticed that the JMSSelector class has dependencies on org.apache.activemq in BlazeDS
4.7.0 where as the version in 4.6 did not. These dependencies are missing from my project
which is probably why I get an exception, they must be an optional dependency of BlazeDS.
> Does the Apache Flex team have any idea which verison BlazeDS 4.7.0 was built on top
of when it came from Adobe? The Original BlazeDS 4.6 nightly builds are still around: http://sourceforge.net/adobe/blazeds/wiki/download%20blazeds%20trunk/
