KB-1221 "Operation ("add") failed... JBAS014802: Cannot resolve expression '${appian.home.ear}'" error returned during JBoss startup

Symptoms

In a new installation, after starting JBoss application server, the following message is returned in the beginning of the deployment:

ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 6) JBAS014612: Operation ("add") failed - address: ([
("subsystem" => "deployment-scanner"),
("scanner" => "appian")
]) - failure description: "JBAS014802: Cannot resolve expression '${appian.home.ear}'"

The deployment then fails.

Cause

The installation was not properly done. The Configure Script should have deployed standalone.conf to <JBOSS_HOME>/bin with the Appian specific parameters. A possible reason is that the repository was accidentally modified, making the folder structure erroneous.

Action

Follow the steps to configure JBoss using the Configure Script again.

Ensure the .configure file is pointing to the correct JBoss location by editing it. Steps on how to do this can be found in KB-1054

Affected Versions

This article applies to all versions of Appian using JBoss application server.
