Inject SY service into @Named bean

l.sroka Jul 24, 2013 8:48 AM

Hello

I was trying to test CDI in simple app. I have one SY service which i want to inject into CDI bean and use it in JSF(richfaces) application.

During deplyoment i have got following stacktrace.

kcbabo Jul 24, 2013 12:06 PM (in response to l.sroka)

The switchyard.xml that's packaged in your WAR is empty in classes/META-INF/switchyard.xml. Try putting the switchyard.xml in src/main/resources in your project and using a pom config like this:

Rob and I had a quick discussion on IRC about this and he brought up an important correction. Your switchyard.xml can be included in the WAR in one of the following two locations:

- WEB-INF/switchyard.xml
- META-INF/switchyard.xml

The version in WEB-INF/classes/META-INF/switchyard.xml is ignored.

I played around with your app a bit more and was able to keep the switchyard.xml in src/main/webapp, so that doesn't have to move. I think your issue might be the fact that the current pom configuration bundles the dependencies in WEB-INF/lib. Add an exclusion similar to the one in the pom I linked to or mark the associated dependencies as provided.

You may want to look at one of the quickstarts that are packaged as war, e.g.: demos/orders or demos/helpdesk

These quickstarts keep switchyard.xml in src/main/resources/META-INF, which is where the tooling will look for the file. I'm not sure how well the SwitchYard tools will work if the file is located in src/main/webapp/.

Something to consider.

In the helpdesk quickstart pom.xml, you can see that the build moves the switchyard.xml into the right place:

<plugin>    
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>
        <packagingExcludes>
            WEB-INF/lib/*.jar,
            WEB-INF/classes/META-INF/switchyard.xml
         </packagingExcludes>
        <webResources>
            <resource>
                <directory>target/classes/META-INF</directory>
                <targetPath>WEB-INF</targetPath>
                <includes>

l.sroka Jul 29, 2013 10:45 AM (in response to l.sroka)

Hello again, let me continue in this topic.
This time i'm really stuck with injection. Let me introduce what is the problem: To my test app hellosy.war i am traying to inject service from another SY project, lets name it switchyard-example.

In hellosy app i have switchyard.xml like this.

                <?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:sca="http://docs.oasis-open.org/ns/opencsa/sca/200912" name="hellosy" targetNamespace="urn:com.example.hellosy:hellosy:1.0.0-SNAPSHOT">
  <sca:composite name="hellosy" targetNamespace="urn:com.example.hellosy:hellosy:1.0.0-SNAPSHOT">
    <sca:component name="InternalTestServiceBean">
      <bean:implementation.bean class="com.example.hellosy.InternalTestServiceBean"/>
      <sca:service name="InternalTestService">
        <sca:interface.java interface="com.example.hellosy.InternalTestService"/>
      </sca:service>
      <sca:reference name="ExternalTestService">
        <sca:interface.java interface="com.example.switchyard.switchyard_example.ExternalTestService"/>
      </sca:reference>
    </sca:component>
    <sca:service name="InternalTestService" promote="InternalTestServiceBean/InternalTestService">
      <sca:interface.java interface="com.example.hellosy.InternalTestService"/>
    </sca:service>
    <sca:reference name="ExternalTestService" multiplicity="0..1" promote="InternalTestServiceBean/ExternalTestService">
      <sca:interface.java interface="com.example.switchyard.switchyard_example.ExternalTestService"/>
    </sca:reference>
  </sca:composite>
</switchyard>

Like you see in switchyard example i have service ExternalService which is injecting into InternalService form hellosy.war app

When i want to deploy this 2 projects (war and jar) i have following error.

I have atached this 2 projects.

Thanks for any help.

Or maybe this is not posible to inject service from another project into other web project.

You can only wire services between applications with a binding (either a service or reference binding). If you know both applications are both deployed side-by-side, you can use binding.sca to allow for in-memory message passing between them. Please check out quickstarts/demos/multiApp as an example.

Aside, in the future, please start new forum threads for new questions, rather than "piggy-backing" on an existing thread. Thanks!

Hi David, sorry for interventing the thread. You said

you can use binding.sca to allow for in-memory message passing between them

but AFAIK, sca-binding use HTTP as a transfer layer, doesn't it? Or you've already changed something in latest release?

kcbabo Sep 12, 2013 11:39 AM (in response to synclpz)

There are two scenarios where HTTP is used for communication with binding.sca:

1) Using the RemoteInvoker client to speak to a service with binding.sca.
2) When clustering is enabled on a binding.sca reference to speak to a service located on another instance with binding.sca on a service (also with clustering enabled).

When clustering is not enabled and the applications communicating with binding.sca are located in the same instance, then all communication is in-process/memory. Here's an example application which uses binding.sca between multiple apps package in an EAR which will not involve any out-of-process communication via HTTP:
