Summary: MBeanProxy attributes

Initial Comment:
The <depends> element in a -service.xml
now supports the configuration of an MBeanProxy to
reference the dependent service.

This is copied from jboss-service_3_2.dtd

<!-- The proxy-type attribute specifies the interface name
that should be exposed on an MBeanProxy pointing at the
dependent
MBean specified by the JMX ObjectName

The special value proxy-type="attribute" will use the
class declared in the MBeanAttributeInfo as the interface
for MBeanProxy.

e.g.
   <mbean code="org.jboss.example.Helper"
name="domain:name=helper"/>
   
   <mbean code="myBean" name="domain:name=x">
      <depends optional-attribute-name="Helper"
               proxy-type="org.jboss.example.HelperMBean"
      >domain:name=helper</depends>
   </mbean>
   
   <mbean code="myBean" name="domain:name=x">
      <depends optional-attribute-name="Helper"
               proxy-type="attribute"
      >domain:name=helper</depends>
   </mbean>
-->
<!ATTLIST depends proxy-type CDATA  #IMPLIED>

And here is an example from the testsuite:

package org.jboss.test.jmx.proxy;
import org.jboss.system.ServiceMBean;
public interface ProxyTestsMBean
   extends ServiceMBean
{
   TargetMBean getProxy();
   void setProxy(TargetMBean proxy);
}

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE server
    PUBLIC "-//JBoss//DTD MBean Service 3.2//EN"
    "http://www.jboss.org/j2ee/dtd/jboss-service_3_2.dtd";>

<server>

   <mbean code="org.jboss.test.jmx.proxy.Target"
          name="jboss.test:name=ProxyTarget"/>

   <!-- simple reference with explicit interface type -->
   <mbean code="org.jboss.test.jmx.proxy.ProxyTests"
          name="jboss.test:name=ProxyTests">
      <depends optional-attribute-name="Proxy" 
              
proxy-type="org.jboss.test.jmx.proxy.TargetMBean"
      >jboss.test:name=ProxyTarget</depends>
   </mbean>

   <!-- nested mbean -->
   <mbean code="org.jboss.test.jmx.proxy.ProxyTests"
          name="jboss.test:name=ProxyTestsNested">
      <depends optional-attribute-name="Proxy" 
              
proxy-type="org.jboss.test.jmx.proxy.TargetMBean">
         <mbean code="org.jboss.test.jmx.proxy.Target"
                name="jboss.test:name=ProxyTargetNested"/>
      </depends>
   </mbean>

   <!-- implicit interface type -->
   <mbean code="org.jboss.test.jmx.proxy.ProxyTests"
          name="jboss.test:name=ProxyTestsAttribute">
      <depends optional-attribute-name="Proxy" 
               proxy-type="attribute"
      >jboss.test:name=ProxyTarget</depends>
   </mbean>

</server>

Adrian
