MBean example for use with Tomcat?

Hi All,

I'd like to use an MBean to configure Hibernate on Tomcat. I can only find examples of MBeans for use with JBoss, so I'm not sure which attributes/values are needed for use with Tomcat. Is there anyone who's done this and could share/explain their Tomcat MBean configuration, or point me to some relevant documentation?

Thanks,
Steve

How will you deploy an MBean without an MBean server?

I'm new to this so maybe I'm misunderstanding it, but doesn't Tomcat 4 support JMX MBeans? I can configure the MBean in my Tomcat server.xml and provide an mbean-descriptor.xml file as is discussed here: http://jakarta.apache.org/tomcat/tomcat ... howto.html

So if that's correct so far, what I'm wondering is what are the appropriate values for the mbean-descriptor.xml when using Hibernate on Tomcat. For instance, a JBoss example shows the following configuration, what values would I use for instance in place of these Jboss specifics:

<mbean code="net.sf.hibernate.jmx.HibernateService" name="jboss.jca:service=HibernateFactory,
name=HibernateFactory">
<depends>jboss.jca:service=RARDeployer</depends>
<depends>jboss.jca:service=LocalTxCM,name=MySqlDS</depends>

<attribute name="MapResources">mappings/Attribute.hbm.xml</attribute>
<attribute name="JndiName">java:/hibernate/HibernateFactory</attribute>
<attribute name="Datasource">java:/MySqlDS</attribute>
<attribute name="Dialect">net.sf.hibernate.dialect.MySQLDialect</attribute>
<attribute name="TransactionStrategy">net.sf.hibernate.transaction.JTATransactionFactory</attribute>
<attribute name="TransactionManagerLookupStrategy">net.sf.hibernate.transaction.JBossTransactionManagerLookup</attribute>
<attribute name="UseOuterJoin">false</attribute>
<attribute name="ShowSql">false</attribute>
<attribute name="UserTransactionName">UserTransaction</attribute>
</mbean>

Frankly, I don't know. I also fail to see why this is better than the traditional (much more flexible) configuration.

A couple of months ago I tried to deploy MBeans on Tomcat 4.1.x. Couldn't get it to work. I finally decided to use JBoss 3.2.3 with Tomcat 5.0.16 running as a SAR. Works like a champ. Just deployed our first installation ten minutes ago. :)

I haven't checked to see if Tomcat 5's MBean support is any better than 4. Doesn't matter. JBoss does it all...
