Class Oc4jConnectionProvider

java.lang.Object
  org.mc4j.ems.impl.jmx.connection.support.providers.AbstractConnectionProvider
      org.mc4j.ems.impl.jmx.connection.support.providers.Oc4jConnectionProvider

public class Oc4jConnectionProvider
extends AbstractConnectionProvider

This Node acts as a connection to an OC4J MBean Server via a MEJB. The MEJB connection is ontained using a J2EE ApplicationClient. This involves a workaround which requires a META-INF/application-client.xml to be present in one of the JAR files which the client is loading. The application-client.xml file can be completely empty, it just needs to be present.

Accordingly, an empty application-client.xml has been added to the src/etc directory and is included in the mc4j_core.jar file when it is created.
