Hi Bill,
I did what you said and still doesnt work!!! I show my code and how
I've implemented the whole things.
I added in the java/org/apache/catalina/deploy/mbeans-descriptors.xml
the follow code:
...
<mbean name="Kaugures"
className="org.apache.catalina.mbeans.AuguresMBean"
description="Augures environment"
domain="Catalina"
group="Resources"
type="org.apache.catalina.deploy.Augures">
<attribute name="className"
description="Fully qualified class name of the managed
object"
type="java.lang.String"
writeable="false"/>
<operation name="HelloWorld"
description="Prueba de AUGURUS"
impact="ACTION"
returnType="java.lang.String">
</operation>
...
And the file (java/org/apache/catalina/deploy/Augurus.java) to
implement the bean is here:
package org.apache.catalina.deploy;
import javax.management.MBeanServer;
import javax.management.MBeanServerFactory;
import javax.management.ObjectName;
import org.apache.tomcat.util.modeler.Registry;
import org.apache.catalina.mbeans.MBeanUtils;
import org.apache.catalina.mbeans.AugurusMBean;
public class Augurus implements AugurusMBean {
private Registry registry = MBeanUtils.createRegistry();
public Augurus() {
ObjectName name = null;
try {
name = new ObjectName("Application:Name=Server,Type=Server");
registry.getRegistry(null, null).registerComponent(this, name,
null);
} catch (Exception e) {
e.printStackTrace();
}
}
// interface method implementations
public String HelloWorld(){
return "Hola";
}
}
And finally, the interface
(java/org/apache/catalina/mbeans/AugurusMBean.java):
package org.apache.catalina.mbeans;
public interface AugurusMBean{
public String HelloWorld();
}
Could you tell what wrong is? Because I didn't find nothing about my
Bean.
Thanks in advance!!!

To use the mbeans-descriptor.xml method, somewhere in your code you
need to do something like:
Registry.getRegistry(null,
null).registerComponent(this, oname, null );
Where 'oname' is the ObjectName that you want to register your
component under. Since you are using TC6, the correct import is:
import org.apache.tomcat.util.modeler.Registry;

Hi Bill,
Yes, I am implementing a custom class that doesnt extend from any
Tomcat class. But I dont know how to self-register, I tried change
the mbeans-descriptor.xml and others things and looks like that
nothing works!!!
Thanks

Chuck's post works for implementing custom Tomcat components (e.g.
a custom Realm extending RealmBase). If you are implementing a
custom class that doesn't extend any Tomcat class, then your class
will have to self-register itself. Since you say you are using
TC6, the default configuration should give you access to the
Registry class to allow you to do it using the
mbeans-descriptor.xml method that the (forked) commons-modeler uses.

Hi Caldarale,
Yes, I use the current version of Tomcat. Thanks for your link,
but I want to know how to implement MBean, because according the
web you gave, I have to add my MBean to the mbeans-descriptor.xml
and also the folder where is contained.
For example, if I want to implement the HelloWorld in
java/org/apache/catalina/mbeans, first of all I have to add to
mbeans-descriptor.xml in java/org/apache/catalina and then also in
java/org/apache/catalina/mbeans.
On the other hand, I've implemented HelloWorld.java in
java/org/apache/catalina/deploy and HelloWorldMBean as interface
in java/org/apache/catalina/mbeans. This implementation is the
correct way? Other way in the same java/org/apache/catalina/deploy
directory contain another mbeans-descriptor.xml file
Can you say me, if I am right?
Thanks a lots!!!

I am searching how to implement a MBean for a class that I
implemented, which add some new funcionality to Tomcat.
Don't suppose you'd care to tell us what version of Tomcat you're
using?
If it's the current level, have you followed these instructions?
