MBeanServerConnectionFactoryBean reconnect

[davidr]

We are trying to use MBeanServerConnectionFactoryBean in our application to make a JMX call to validate connectivity. If the server he is connected to goes down, we do not see anyway to force the bean to reconnect. Are we missing something?

Thanks,
David

<bean id="jmxConnection" class="org.springframework.jmx.support.MBeanServer ConnectionFactoryBean">
<property name="serviceUrl" value="service:jmx:rmi:///jndi/rmi://localhost:10123/jmxrmi" />
</bean>

<bean id="smppJmxController" class="org.springframework.jmx.access.MBeanProxyFa ctoryBean">
<property name="objectName" value="com.myname:name=MyClassJmxController"/>
<property name="proxyInterface" value="MYCLASSNAME"/>
<property name="server"><ref bean="jmxConnection"/></property>
</bean>

Now I can connect to the MYCLASSNAME however if for any reason the jmx server goes down and is then restarted or available again I cannot connect to it. It is a MVC webapp by the way the following is the error i get on the controller trying to use the mbean

org.springframework.jmx.access.InvocationFailureEx ception: JMX access failed; nested exception is java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused

I want ot be able to somehoe have the server reconnect so that my calls will be successful am I doing this totally wrong?

Any pointers appreciated.

Thanks
Paul

I am now trying to reconect by call refresh in the webapplicationContext but I get the following message.

[org.springframework.beans.factory.support.Disposab leBeanAdapter] - Couldn't invoke destroy method of bean with name 'jmxConnection'
java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:

Needless to say I am not getting anywhere fast with this issue please help

We subclassed the Spring class and put the reconnect in ourselves.

We subclassed the Spring class and put the reconnect in ourselves.

Would you be willing to share? This would be a fantastically useful feature for me.

Could someone tell me if this code really works? Seems like some nub (like me) first shot.

I didn't use it. Instead, I rely on Spring to handle the server-based JMX connector, but use a custom, non-Spring client that connects for each method invocation.
