Java EE @Resource没有映射到web.xml

Question

I am trying to develop a web application with a java back end but I need to track if the tasks are complete and I am using the ManagedExecutorService for this.

I am trying to use the @Resource annotation to inject a ManagedExecutorService as follows.

@Resource(name = "myExecutionService")
private ManagedExecutorService mExecutionService;

web.xml:

<resource-env-ref>
    <resource-env-ref-name>myExecutionService</resource-env-ref-name>
    <resource-env-ref-type>javax.enterprise.concurrent.ManagedExecutorService</resource-env-ref-type>
</resource-env-ref>

but I keep getting an error saying that I am missing the "Services with missing/unavailable dependencies"

13:52:31,207 INFO  [org.jboss.as.server] (management-handler-threads - 158) JBAS015870: Deploy of deployment "tbm-core-1.0.war" was rolled back with failure message {"JBAS014671: Failed services" => {"jboss.deployment.unit.\"tbm-core-1.0.war\".WeldService" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"tbm-core-1.0.war\".WeldService: org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [TestBedManager] with qualifiers [@Default] at injection point [[field] @Inject private com.shenick.teravm.core.ws.TestBedManagerWebService.testBedManager]"},"JBAS014771: Services with missing/unavailable dependencies" => ["jboss.naming.context.java.module.\"tbm-core-1.0\".\"tbm-core-1.0\".env.myExecutionServicejboss.naming.context.java.jboss.resources.myExecutionServiceMissing[jboss.naming.context.java.module.\"tbm-core-1.0\".\"tbm-core-1.0\".env.myExecutionServicejboss.naming.context.java.jboss.resources.myExecutionService]"]}

Answer 1

I have figured out the problem and it's because ManagedexecutorService is java 7 only apparently and jboss 7.1.1 will not deploy apps that use threads.

to solve this I will need to upgrade to EAP 6.1 (new name for jboss).

If you want just use the default implementation, use

@Resource(mappedName="java:comp/DefaultManagedExecutorService")

In this case, you don't need to specify it in web.xml.

If you want to use your own implementation, I think you should configure your application server resources first (set it with your implementation).

EDIT:

I found this by chance: How to Configure Scheduled Tasks in Wildfly . It could help you, I think.
