Standard MBean Deployment to JMX console problems
Greetings,
Currently for development I'm using JBoss 3.2.2, and I am trying to deploy a very simple MBean to the JMX console. Eventually, we will use it to view the log file of the JBoss server from the jmx console, but right now I am just trying to get a skeleton "Hello World" to work.
Step 1: I wrote the MBean interface class
package mil.navy.erm;
public interface PlainViewerMBean {
//the public interface for the Plain Viewer JMX plugin.
/**
* Returns a String that is the entirety of the JBoss logfile
*/
public String getLog();
}
Step 2: I wrote the implementing class skeleton "Hello World" version
package mil.navy.erm;
public class PlainViewer implements PlainViewerMBean {
public String getLog() {
return "Hello World";
}
}
Step 3: After compiling into a jar file, I initially tried several things to attempt to get JBoss to recognize and deploy the MBean to the jmx console following the directions of many tutorials. Some said to create and modify a file jboss-service.xml inside the META-INF directory of my jar file. Others mentioned this, but said to use a .sar file instead. Here is the content of my jboss-service.xml inside of the META-INF of my .sar file.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE server>
When starting JBoss I recieve the following error
Incompletely deployed packages:
[org.jboss.deployment.DeploymentInfo@52cc391f { url=file:/C:/jboss-3.2.2/server/default/deploy/LogViewer.sar/ }

So something is wrong with the registration of the MBean, but I can't figure out what it is. Any help you guys can offer would be greatly appreciated.
