MalformedObjectNameException: Unterminated key property part

[raoul schmidiger]

Hi,

I have a problem with registring beans in the rmiregistry. I am using Spring 2.1, Java 1.6, Tomcat 5.5 and all on windows xp.

I have the following JMX related spring setup

	<bean id="registry"
		class="org.springframework.remoting.rmi.RmiRegistryFactoryBean">
		<property name="port" value="1099" />
	</bean>

	<bean id="serverConnector"
		class="org.springframework.jmx.support.ConnectorServerFactoryBean"
		depends-on="registry">
		<property name="objectName" value="connector:name=rmi" />
		<property name="serviceUrl"
			value="service:jmx:rmi://localhost/jndi/rmi://localhost:1099/myconnector" />
	</bean>

	<bean id="exporter"
		class="org.springframework.jmx.export.MBeanExporter"
		lazy-init="false">
		<property name="autodetect" value="true" />
		<property name="beans">
			<map>
				<entry key="bean:testBean1" value-ref="userService" />
			</map>
		</property>
		<!-- property name="server">
			<bean class="platform.package.MBeanServerLocator"
				factory-method="locateMBeanServer" />
		</property -->
	</bean>

I first start an rmiregistry by hand (the one spring starts is too slow and I get a ConnectException).
Then the MalformedObjectNameException: Unterminated key property part appears, as spring tries to export the MBean "userService" to the registry.

(If i leave the line <property name="autodetect" value="true" /> away, no exception is thrown, but also none of my MBean's appear in JConsole.)

Here is the trace:

I read all about JMX I could find, but nothing could hint me into the right direction.

Any help appreciated...

It looks like the bean mapping key in your MBeanExporter configuration is not a valid MBean ObjectName:

<entry key="bean:testBean1" value-ref="userService" />

Try changing the key in this mapping to:

<entry key="bean:name=testBean1" value-ref="userService" />

See here for more details on the format of JMX ObjectNames:
