when I deploy a new version (3.0.1) of my webapp on Tomcat 8 [on tomcat is deployed an older version (3.0.0)] i get this exception:

Failed to register LiveBeansView MBean; nested exception is javax.management.InstanceAlreadyExistsException

In web.xml of my application i have this configuration:

<context-param>  
    <param-name>spring.profiles.active</param-name>  
    <param-value>security-base,security-api</param-value>  
</context-param>  
<context-param>  
    <param-name>spring.profiles.default</param-name>  
    <param-value>security-base,security-api</param-value>  
</context-param>
<context-param>  
    <param-name>spring.liveBeansView.mbeanDomain</param-name>  
    <param-value>security-base,security-api</param-value>  
</context-param>

Anyone can help me ?

Since you have two deployments on your Tomcat server for the same application (albeit different versions), you'll need to name your MBeans differently. Since MBeans are accessed per server (via a single JMX endpoint), each MBean identifier has to be separate.

You have a few options to make these unique in your apps:

  1. The simplest solution is to set endpoints.jmx.unique-names to true and let Spring Boot make the MBean paths unique for you, rather than using default names. .
  2. Alternatively, you can change the MBean domain by setting thespring.jmx.default-domain=applicationname for the application

  3. And you might likely not need this, but adding here for completeness; if you're manually loading your beans in Spring Configuration, you can add the EnableMBeanExport specifying a domain as such:

    @Configuration
@EnableMBeanExport(defaultDomain="first")
public class MBeanConfig {...}

In my application 'spring.profiles' were added to get rid of debug log. spring jndi NamingException: Name [spring.liveBeansView.mbeanDomain] is not bound in this Context I fixed this issue by modifying web.xml for each deployed application making param-value unique per web.xml.

<param-value>prod</param-value>

vs

<param-value>test</param-value>

For example:

Production:

  <context-param>  
    <param-name>spring.profiles.active</param-name>  
    <param-value>prod</param-value>  
  </context-param>  
  <context-param>  
    <param-name>spring.profiles.default</param-name>  
    <param-value>prod</param-value>  
  </context-param>
  <context-param>  
    <param-name>spring.liveBeansView.mbeanDomain</param-name>  
    <param-value>prod</param-value>  
  </context-param>

Testing

  <context-param>  
    <param-name>spring.profiles.active</param-name>  
    <param-value>test</param-value>  
  </context-param>  
  <context-param>  
    <param-name>spring.profiles.default</param-name>  
    <param-value>test</param-value>  
  </context-param>
  <context-param>  
    <param-name>spring.liveBeansView.mbeanDomain</param-name>  
    <param-value>test</param-value>  
  </context-param>
