RESTEasyPublishException

[anikulin]

Hello

In my project I have a switchyard bean with a reference to another bean, and when I'm trying to add RESTEasy binding to this reference at deployment I have such exception:

23:44:52,614 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC00001: Failed to start service jboss.deployment.unit."metaKonnector.jar".SwitchYardService: org.jboss.msc.service.StartException in service jboss.deployment.unit."metaKonnector.jar".SwitchYardService: org.switchyard.component.resteasy.RESTEasyPublishException: java.lang.NullPointerException

My switchyard.xml is:

<?xml version="1.0" encoding="UTF-8"?>
<switchyard xmlns="urn:switchyard-config:switchyard:1.0" xmlns:bean="urn:switchyard-component-bean:config:1.0" xmlns:resteasy="urn:switchyard-component-resteasy:config:1.0" xmlns:sca="http://docs.oasis-open.org/ns/opencsa/sca/200912" xmlns:soap="urn:switchyard-component-soap:config:1.0" xmlns:transform="urn:switchyard-config:transform:1.0" name="metaConnector" targetNamespace="urn:com.magick:metaConnector:0.0.1-SNAPSHOT">

        <resteasy:contextPath>metaConnector</resteasy:contextPath>
      </resteasy:binding.rest>
    </sca:service>
  </sca:composite>
</switchyard>

SwitchYard scheme in Eclipse looks like this:

And after adding RESTBinding component I also have such error in Eclipse:

cvc-complex-type.2.4.a: Invalid content was found starting with element 'resteasy:binding.rest'. One of '{"http://docs.oasis-open.org/ns/opencsa/sca/200912":binding, "http://docs.oasis-open.org/ns/opencsa/sca/200912":callback, "http://docs.oasis-open.org/ns/opencsa/sca/200912":requires, "http://docs.oasis-open.org/ns/opencsa/sca/200912":policySetAttachment, "http://docs.oasis-open.org/ns/opencsa/sca/200912":extensions}' is expected.

Can you help me please to solve these issues?

Thanks

Have you enabled RESTEasy component inside the AS7 configuration? If you use standalone.xml then it should have subsystem defined like this

 <subsystem xmlns="urn:jboss:domain:switchyard:1.0">
    <modules>
        <module identifier="org.switchyard.component.bean" implClass="org.switchyard.component.bean.deploy.BeanComponent"/>
        <module identifier="org.switchyard.component.soap" implClass="org.switchyard.component.soap.deploy.SOAPComponent"/>
        <module identifier="org.switchyard.component.camel" implClass="org.switchyard.component.camel.deploy.CamelComponent"/>
        <module identifier="org.switchyard.component.rules" implClass="org.switchyard.component.rules.deploy.RulesComponent"/>
        <module identifier="org.switchyard.component.bpm" implClass="org.switchyard.component.bpm.deploy.BPMComponent"/>
        <module identifier="org.switchyard.component.bpel" implClass="org.switchyard.component.bpel.deploy.BPELComponent"/>
        <module identifier="org.switchyard.component.hornetq" implClass="org.switchyard.component.hornetq.deploy.HornetQComponent"/>

        <module identifier="org.switchyard.component.remote" implClass="org.switchyard.component.remote.deploy.RemoteComponent">
            <properties>
                <cache-name>
                    cluster
                </cache-name>
            </properties>
        </module>
        <module identifier="org.switchyard.component.resteasy" implClass="org.switchyard.component.resteasy.deploy.RESTEasyComponent"/>
    </modules>
</subsystem>

Also ensure that the jaxrs susbsytem is also enabled

 <extension module="org.jboss.as.jaxrs"/>

Yes, I have such configuration, and on another project RESTBinding works, but here it doesn't.

[mageshbk]

Could you tell us the version of AS7 in this environment? Is there any upgrade done to the RESTEasy subsystem? Could you attach the logs? When you say another project, is it just another deployment in the same server or a complete server+application combination?

[anikulin]

I use SwitchYard 6.0 Final and  RESTEasy jar in module is also 6.0-Final version.
Yes, I mean just another project deployed on the same server with the same configuration.

[mageshbk]

Looks like you are trying to bind a WebService as well as the RESTEasy service onto the same context path: metaConnector

http://localhost:8080/metaConnector/StrategyService

I have created a JIRA to fix the NPE and throw an appropriate message. Please use a different context path for the REST endpoints

https://issues.jboss.org/browse/SWITCHYARD-1206.

[anikulin]

Yes, that's working with another context path. Thanks a lot.

Hi Anton,

You are welcome! Did your Eclipse (tooling) issue also got re-solved? If it isn't I will ask the tooling specialists to have a look.

You should change the class definition of the identifier below, from "atom" to "rss" and then restart the server.

Current:

<module identifier="org.switchyard.component.camel.rss" implClass="org.switchyard.component.camel.atom.deploy.CamelRSSComponent"/>

New:

<module identifier="org.switchyard.component.camel.rss" implClass="org.switchyard.component.camel.rss.deploy.CamelRSSComponent"/>
