JMX in Weblogic 9

[dan19460]

Can anyone provide a configuration excerpt for Weblogic 9 and JMX?

I'm having a really frustrating time trying to connect to the embedded MBeanServer in WL9. Here is what I have so far but the exporter fails at startup because it says it can find an MBean Server...

<bean id="exporter" class="org.springframework.jmx.export.MBeanExporte r">
<property name="beans">
<map>
<!-- there is a bean named 'repository' defined elsewhere -->
<entry key="bean:name=repository1" value-ref="repository"/>
</map>
</property>
</bean>

<!-- expose weblogic server's runtime mbeanserver connection -->
<bean id="runtimeMbeanServerConnection"
class="org.springframework.jmx.support.MBeanServer ConnectionFactoryBean">
<property name="serviceUrl"
value="service:jmx:t3://${WS_HOST}:${WS_PORT}/jndi/weblogic.management.mbeanservers.runtime"/>
<property name="environment">
<props>
<prop key="java.naming.security.principal">${WS_USERNAME }</prop>
<prop key="java.naming.security.credentials">${WS_USERNA ME}</prop>
<prop key="jmx.remote.protocol.provider.pkgs">weblogic.m anagement.remote</prop>
</props>
</property>
</bean>

Basically, I need to know how to set the "server" property on the exporter. Thanks, in advance.

Dan.

Have you looked at WebLogicMBeanServerFactoryBean?

His example is taken from the BEA dev2dev site, so I imagine its what BEA recommends for Weblogic 9.

The problem with that example is there is a typo:

         <prop key="java.naming.security.principle">
            ${WS_USERNAME}</prop>
         <prop key="java.naming.security.credentials">
            ${WS_USERNAME}</prop>

should read:

         <prop key="java.naming.security.principle">
            ${WS_USERNAME}</prop>
         <prop key="java.naming.security.credentials">
            ${WS_PASSWORD}</prop>

Unless of course your username and password values are the same for your server.

Of course the various variables would have to inserted into the appliation context using a PropertyPlaceholderConfigurer, something they don't mention in the BEA example.

Also, shouldn't it be

java.naming.security.principal

The WeblogicMBeanServerFactoryBean utilizes the weblogic.management.Helper class to locate the MBeanServer (via the MBeanHome interface). This interface has been deprecated for 9.0. According to the docs:

"Deprecated. 9.0.0.0 Replaced by standard JMX design patterns in which clients use the javax.management.MBeanServerConnection interface to discover MBeans, attributes, and attribute types at runtime."

That is why I used the example from the article by Rod and the BEA folks at this url:

http://dev2dev.bea.com/pub/a/2005/09...ic_server.html

(Notice the configuration on page 4).

However, what the article doesn't tell you is how to configure an "exporter" in this environment. Setting the "server" property on the MBeanExporter to point to this MBeanServerConnectionFactoryBean yields a class cast at startup. What am I missing?

Thanks all.

BTW,

In my development environment, the username and passwords are the same so the fact that the property placeholders reference the same property don't make a difference to me. Also, I did catch the typo on 'principal'. It will error if you use 'principle'.
