Hi,

did you define the class-path in the MANIFEST.MF of EJB-Main.jar like this?

Class-Path: EJB-MainClient.jar

If this does not work, you could move the EJB-MainClient.jar to a lib/ folder in your ear, so that you would have this layout:

EJB-MainEAR.ear

        JPA-Main.jar (JPA Project)

        EJB-Main.jar (EJB Session Beans Project)

        GWT-Main.war (Web Project)

        lib/

                EJB-MainClient.jar (EJB Interfaces Project)

JEE5 defines that jars inside the lib/ folder have to be included in the class path for the contained modules.

Imho this would be the best way anyway to distinguish modules from utility jars.

Kind regards,

Robert

Subject: [jboss-as7-dev] Classpath problems in EAR project

Hi!

I am migrating a project from JAS 6 Final to JAS 7.0.2 Final.

Here is the structure of my application:

EJB-MainEAR.ear
        JPA-Main.jar (JPA Project)
        EJB-MainClient.jar (EJB Interfaces Project)
        EJB-Main.jar (EJB Session Beans Project)
        GWT-Main.war (Web Project)

I read the article https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7 and i am aware of the property ear-subdeployments-isolated.

I tried to add this property to the file C:\jboss7\standalone\configuration\standalone.xml setting it to FALSE.
<subsystem xmlns="urn:jboss:domain:ee:1.0">
        <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
</subsystem>

But i get this error message whe starting JBoss.
"SistemaSession" is the EJB interface inside EJB-MainClient.jar.

Then i tried to add a jboss-deployment-structure.xml file to the EAR, defining all the dependencies.

<jboss-deployment-structure>
  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
  <deployment>
    <dependencies>
      <module name="com.keyworks.k3" />
    </dependencies>
  </deployment>
  <sub-deployment name="JPA-Main.jar">
  </sub-deployment>
  <sub-deployment name="EJB-MainClient.jar">
    <dependencies>
      <module name="deployment.EJB-MainEAR.ear.JPA-Main.jar:main" />
    </dependencies>
  </sub-deployment>
  <sub-deployment name="EJB-Main.jar">
    <dependencies>
      <module name="deployment.EJB-MainEAR.ear.JPA-Main.jar:main" />
          <module name="deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main" />
    </dependencies>
  </sub-deployment>
  <sub-deployment name="GWT-Main.war">
    <dependencies>
      <module name="deployment.EJB-MainEAR.ear.JPA-Main.jar:main" />
          <module name="deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main" />
    </dependencies>
  </sub-deployment>
</jboss-deployment-structure>

And the error message when starting JBoss was:

10:43:37,194 INFO  [org.jboss.as.server.controller] (DeploymentScanner-threads - 2) Deployment of "EJB-MainEAR.ear" was rolled back with failure message {"Services with missing/unavailable dependencies" => ["jboss.deployment.subunit.\"EJB-MainEAR.ear\".\"GWT-Website.war\".CONFIGURE_MODULE missing [ jboss.module.information.service.\"deployment.EJB-MainEAR.ear.JPA-Main.jar:main\".main, jboss.module.information.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main\".main ]","jboss.deployment.subunit.\"EJB-MainEAR.ear\".\"EJB-Main.jar\".CONFIGURE_MODULE missing [ jboss.module.information.service.\"deployment.EJB-MainEAR.ear.JPA-Main.jar:main\".main, jboss.module.information.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main\".main ]","jboss.deployment.subunit.\"EJB-MainEAR.ear\".\"JPA-Main.jar\".POST_MODULE missing [ jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar\".main, jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-Main.jar\".main ]","jboss.module.service.\"deployment.EJB-MainEAR.ear\".main missing [ jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar\".main, jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-Main.jar\".main ]","jboss.deployment.subunit.\"EJB-MainEAR.ear\".\"EJB-MainClient.jar\".CONFIGURE_MODULE missing [ jboss.module.information.service.\"deployment.EJB-MainEAR.ear.JPA-Main.jar:main\".main ]","jboss.deployment.subunit.\"EJB-MainEAR.ear\".\"TST-Main.war\".CONFIGURE_MODULE missing [ jboss.module.information.service.\"deployment.EJB-MainEAR.ear.JPA-Main.jar:main\".main, jboss.module.information.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main\".main ]","jboss.deployment.unit.\"EJB-MainEAR.ear\".POST_MODULE missing [ jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.GWT-Website.war\".main, jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar\".main, jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-Main.jar\".main, jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.TST-Main.war\".main, jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.GWT-Main.war\".main ]","jboss.deployment.subunit.\"EJB-MainEAR.ear\".\"GWT-Main.war\".CONFIGURE_MODULE missing [ jboss.module.information.service.\"deployment.EJB-MainEAR.ear.JPA-Main.jar:main\".main, jboss.module.information.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main\".main ]","jboss.module.service.\"deployment.EJB-MainEAR.ear.JPA-Main.jar\".main missing [ jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-MainClient.jar\".main, jboss.module.spec.service.\"deployment.EJB-MainEAR.ear.EJB-Main.jar\".main ]"]}

What i need to do for my modules (JAR and WAR) to see each other and get this working?
