The usage of DeploymentManager should be

deploymentManager.distribute(name, isCopyContent);
deploymentManager.start(name);
deploymentManager.stop(name);
deploymentManager.remove(name);

instead of:

DeploymentProgress distribute = getDeploymentManager().distribute(name, getManagedURL(name), copyCon
tent);
distribute.run();

if (copyContent)
{
DeploymentProgress start = getDeploymentManager().start(name);
start.run();
}

DeploymentProgress stop = getDeploymentManager().stop(names);
stop.run();

if (copyContent)
{
DeploymentProgress undeploy = getDeploymentManager().undeploy(names);
undeploy.run();
}
