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.
> BlazeDS 4.7.0 incompatible replacement for BlazeDS 4.6
> ------------------------------------------------------

> Key: FLEX-34886
> URL: https://issues.apache.org/jira/browse/FLEX-34886
> Project: Apache Flex
> Issue Type: Bug
> Components: BlazeDS
> Affects Versions: BlazeDS 4.7
> Reporter: Robert Hunt
>
> 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/
