JBoss Deployment war error on startup - No content hash available

In this post, we are going to discuss the deployment problem that prevents JBoss Server to start properly.

Error starting Java JBoss server (in domain mode)

The JBoss Server logs, in this case, looks like below:

10:16:57,337 INFO [org.jboss.modules] JBoss Modules version 1.1.3.GA-redhat-1
10:16:57,498 INFO [org.jboss.msc] JBoss MSC version 1.0.2.GA-redhat-2

10:16:57,686 INFO [org.jboss.as] JBAS015899: JBoss EAP 6.0.1.GA

10:16:58,340 INFO [org.jboss.as.server.deployment.scanner] JBAS015003: Found abc.war in deployment directory. To trigger deployment create a file called abc.war.dodeploy

10:16:58,348 ERROR [org.jboss.as.controller.management-operation] JBAS014613: Operation ("add") failed - address: ([("deployment" => "abc-ABC.0.0.21.war")]) - failure description: "JBAS018717: No deployment content with hash 28c2ce34057a6bd5ebf2c28f9d114814faa66b8a is available in the deployment content repository for deployment 'abc-ABC.0.0.21.war'.

This is a fatal boot error. To correct the problem, either restart with the --admin-only switch set and use the CLI to install the missing content or remove it from the configuration, or remove the deployment from the xml configuraiton file and restart."

10:16:58,351 ERROR [org.jboss.as.server.deployment.scanner] JBAS014654: Composite operation was rolled back

10:16:58,351 FATAL [org.jboss.as.server] JBAS015957: Server boot has failed in an unrecoverable manner; exiting. See previous messages for details.

10:16:58,358 INFO [org.jboss.as] JBAS015950: JBoss EAP 6.0.1.GA (AS 7.1.3.Final-redhat-4) stopped in 3ms

This error also occurs when we delete directory standalone\data.. and then try to redeploy the same application war. The JBoss server unable to delete entries defined in standalone.xml with the same hash for the deployed application.

The standalone.xml looks like below:

<deployments>
    <deployment name="abc-ABC.0.0.21.war" runtime-name="abc-ABC.0.0.21.war">
         <content sha1="28c2ce34057a6bd5ebf2c28f9d114814faa66b8a"/>
    </deployment>
</deployments>

Removing the entries manually for the application having defined hash solved this problem and JBoss server will start successfully without error.
