expected "OK" message

Answer 1

The error indicates your war was deployed, but failed to start. Check your tomcat logs for more detailed errors.
Also to verify this issue is not related to your Jenkins job configuration, could you verify whether manually deploying the war works? If manually deploying works, then the issue is likely in the Jenkins job configuration. If manual deployment fails (with same error), the problem can be found in the tomcat logs.
