Wildfly 9.0.1.Final: EAR deployment failed

I am trying to deploy my struts based web application on Wildfly 9.0.1.Final.

I am deploying as an .ear file that contains .war/.jar(EJB) files.

But it gives me an error during deployment.

Error Stacktrace:

Failed to define class AuditMDB in Module "deployment.webapp.ear.EJB.jar:main" from Service Module Loader: java.lang.LinkageError: Failed to link AuditMDB (Module "deployment.webapp.ear.EJB.jar:main" from Service Module Loader)

Please help

You have to make sure your datasource is defined. In your standalone-full.xml you need to include the definition, something like:

<datasource jndi-name="java:datasources/WEBFDMS" pool-name="WEBFDMS" enabled="true" use-java-context="true">
    <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
    <driver>h2</driver>
    <security>
        <user-name>sa</user-name>
        <password>sa</password>
    </security>
</datasource>

"java:datasources/WEBFDMS" might have to be "java:jboss/datasources/WEBFDMS"

Of course, this datasource definition will simply create an in-memory datasource. In order to connect to a running database (mysql, oracle, etc) you will have to configure it differently.
