jboss: why does deployment fail?

Question

Java

Good day. When deployed to a remote server through the control panel (port 9990), the following error occurs

Unexpected HTTP response: 500

Request
{
    "address" => [("deployment" => "education.war")],
    "operation" => "deploy"
}

Response

Internal Server Error

    "outcome" => "failed",
    "failure-description" => {"JBAS014671: Failed services" => {"jboss.undertow.deployment.default-server.default-host./education" => "org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./education: Failed to start service

    "rolled-back" => true
}

As I understand it, the problem is in Impl classes, like DAO and services, but everything works fine on the local server. How to decide?

As far as I understand from your piece of log, JBoss cannot initialize the field
'sessionFactory'due to an error java.lang.IncompatibleClassChangeError.
Perhaps the problem is in different versions of the libraries. Are the versions of JBoss the same? Compare the contents of the folder %JBOSS_HOME%/moduleson the local machine and on the remote machine.
Usually, when JBoss fails to deploy a WAR, there are Stack Trace errors in the log. It would be nice to have a look at it.
