Tomcat server not working anymore after a stop and restart

I've got an error related to tomcat server. I shut down my server (took a while) and then when a start the server back, an error appears :

org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [com.amadeus.security.CCDVAccess@2a9cce4a] with key 'CCDVAccess'; nested exception is javax.management.InstanceAlreadyExistsException: com.amadeus.security:name=CCDVAccess

I know that the error is not related to the code, because nothing change. I try

  • to stop and restart many times,
  • to change the version of the WAR I was using.
  • to delete the logs and the folder work/catalina

I do not know what else I should try, so I hope some of you has I idea about that. I really think the issue is coming from tomcat but I'm not sure.

Thank for your help Sébastien

Edit: I solved my issue it was a stupid mistake. I did a backup of my WAR file without changing the extension... Therefore tomcat was launching 2 identicals servers. Thanks guys for your help

Solution

  • it seems you have two Spring Boot apps in the same JVM so you need to segregate the MBean namespace. the first log error tell you that.

    org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [com.amadeus.security.CCDVAccess@2a9cce4a] with key 'CCDVAccess'; nested exception is javax.management.InstanceAlreadyExistsException: com.amadeus.security:name=CCDVAccess
