Issue fixed in MI master branch after 1.0.0 is released.

EnricoDamini commented 4 years ago

Hello, I've the same problem with the same code of the first thread. I've download the microintegrator 1.1.0 (community edition) from this link https://github.com/wso2/micro-integrator/releases/tag/v1.1.0 and when I deploy the .car I have the same error:

Caused by: org.apache.synapse.SynapseException: Unknown mediator referenced by configuration element : {http://wso2.org/carbon/rules}rule at org.apache.synapse.config.xml.MediatorFactoryFinder.getMediator(MediatorFactoryFinder.java:218) at org.apache.synapse.config.xml.AbstractListMediatorFactory.addChildren(AbstractListMediatorFactory.java:46) at org.apache.synapse.config.xml.SequenceMediatorFactory.createAnonymousSequence(SequenceMediatorFactory.java:70) at org.apache.synapse.config.xml.rest.ResourceFactory.configureSequences(ResourceFactory.java:107) at org.apache.synapse.config.xml.rest.ResourceFactory.createResource(ResourceFactory.java:50) at org.apache.synapse.config.xml.rest.APIFactory.createAPI(APIFactory.java:94) at org.apache.synapse.deployers.APIDeployer.deploySynapseArtifact(APIDeployer.java:47) ... 64 more

If i use wso2ei-6.6.0 the API work.

pavanandhukuri commented 3 years ago

Has the fix for this been released? If not, is there an alternative to work with for now?

guidospadotto-profesia commented 3 years ago

The Rule mediator is not included in Mi runtime. See "Features removed" from https://ei.docs.wso2.com/en/latest/micro-integrator/overview/about-this-release-7.1.0/

pavanandhukuri commented 3 years ago

Is there a workaround for this? Like a connector which is made available to replace this feature?

pavanandhukuri commented 3 years ago

I think this is severely mishandled. The rule mediator is removed from the runtime but it is available on the Tooling and the documentation also includes its usage.

https://ei.docs.wso2.com/en/latest/micro-integrator/references/mediators/rule-Mediator/

It is misleading..

gspadotto commented 3 years ago

I have created a Documentation issue some time ago about this: https://github.com/wso2/docs-ei/issues/2219

One might use Integration Studio to write Integration Projects for EI6.x too, where the Rule mediator is still available. This is the reason - I think - why that mediator is still available in Integration Studio.

I do not work for WSO2.
